Jana Lasser

Postdoctoral Researcher at Graz University of Technology

I am a PostDoc at David Garcia's Computational Social Science lab at the Graz University of Technology and the Complexity Science Hub Vienna.

Drawing from my experience in nonlinear dynamical systems, my current research activity centres around emergent phenomena in complex social systems. I employ methods from machine learning, data science, sociophysics to understand a diverse range of topics, from emotion dynamics to the spread of diseases and misinformation in the field of Computational Social Science.

For my PhD in physics, I conducted research on pattern formation in salt deserts at the Max Planck Institute for Dynamics and Self-Organization and received my degree from the Georg-August-University in Göttingen, Germany in 2019.

Next to my research I care deeply about how the scientific community functions and dysfunctions. I try to improve reproducibility and transparency of research by following Open Science practices and being an outspoken and active proponent of Open Science practices. During my time as the president of the Max Planck PhD association I learned about the rampant mental health problems of many academics and joined the COST Action on Researcher Mental Health to help change the academic system for the better.

The influence of behavioural factors on measure adherence during the COVID-19 pandemic

Image showing the hypothetical time development of prosiciality, infection rate, and mobility and hygiene behaviour in a population during a pandemic The COVID-19 pandemic is a public health crisis of unprecedented scale in modern times. As long as there is no medical answer, social and behavioural measures are the only available way to curb the spread of the pandemic. The unfolding of the epidemic in a given country therefore greatly depends on its implemented social and behavioural countermeasures and the population’s willingness to adhere to them. There is strong evidence that prosociality drives the willingness to adhere to measures, which is subject to complex social and emotional interaction processes. The aim of this project is to understand how social and emotional interaction processes can sustain prosocial behaviour that prevents the spreading of COVID-19. more...

To do so, I plan to combine large-scale data analysis of social media data with computational modelling of epidemic spreading and human behaviour. To this end I am developing a dynamical model for prosociality which is coupled to a model of epidemic spread. The model of prosociality dynamics is parameterized using empirical measurements of prosocial language on social media and validated by predicting population mobility changes. In collaboration with Allesandro Vespigniani and Viola Priesemann I will combine insights gained in this project with epidemic models, and evaluate if these models can be improved by including behavioural changes and prosocial behaviour. This work has been funded within the scope of a Marie Curie individual fellowship, starting from February 2022.

Here is a recent talk that outlines my research agenda in more detail.

Interventions to prevent the spread of misinformation: scaling up to social media

The rapid spread of misinformation is rapidly becoming a threat to the cohesion of society. While it is still a matter of debate if social media platforms inherently favour the spread of misinformation, the possibilities of rapid online dissemination of information at least exacerbates the problem. A range of interventions to lower a person's tendencie to believe and/or spread misinformation have been shown to work in the laboratory setting. Nevertheless, the big challenge is to scale these interventions up and test whether they also work in the context of a big social media platform. more...

In this project, we collaborate with behavioral psychologists around Stephan Lewandowsky and Sander van der Linden . These behavioural psychologists developed videos in which strategies that are commonly used to help spread misinformation, such as extreme emotionalisation of content, are pointed out to the viewer. We deliver these videos as intervention to social media users and measure the effect of the intervention on a range of behavioural parameters, such as sharing behaviour and emotionalisation of language.

The effectiveness of counterspeech strategies

Hatespeech is an increasingly common phenomenon on social media platforms. Oftentimes, organized right-wing troll groups band together to attack profiles and comments of celebrities or news organisations. Next to content deletion, counterspeech can be an effective means to steer the conversation away from toxicity and hate. In this project, we want to assess the effectiveness of a range of different counterspeech strategies. more...

In this project, we collaborate with Mirta Galesic and her team at the Santa Fe Institute. We use data from a unique natural experiment that occured in Germany several years ago: in this natural experiment, both hate- and counterspeech groups organised their activity on Twitter and self-labelled as members of the respective groups. We automatically identify different counterspeech strategies using multilingual transformer models fine-tuned to a labelled dataset and identify the impact of each strategy on the ensuing conversation on Twitter.

Spread of SARS-CoV-2 in nursing homes, schools and universities

Illustrative image of the spread of an infection through the contact network of patients in a nursing home In this project I created an agent based simulation to explore the spread of COVID-19 in "small" communities, such as nursing homes schools and universities. The model combines the interaction of individual agents with a contact network of people that live or work in the given community. The model offers the possibility to explore the effectiveness of various testing, tracing and quarantine strategies. In addition, non-pharmaceutical intervention measures such as wearing masks and ventilating rooms as well as different levels of vaccine effectiveness and vaccination rates can be explored. Different virus variants can be modelled very flexibly by adapting the epidemiological parameters of the virus. more...

Image showing the risk profile of a farm for certain dairy cattle diseases such as ketosis and lameness The model simulates several types of agents, for example students and teachers in the school context. Agents have explicitly defined contact networks that are defined through their daily interactions. The contact network defines which agents interact with which other agents and different contact venues modulate infection transmission risk. For example infection risk is drastically increased for agents that share a household, as compared to interactions that occur in the school. In every step (day) of the simulation, agents interact according to their interaction rules and can transmit an infection. Depending on their infection state, an agent has one of five states: susceptible (S), exposed (E), infected (I), removed (R) or quarantined (X). In addition, agents can develop symptoms, can be testable and can have a pending test result (tested). The simulation is calibrated using empirical observations of outbreaks in the respective context. After the simulation is calibrated, it allows for the implementation of different prevention strategies and combinations thereof in what we call "scenarios". For every scenario, we then introduce a single infection into the community and observe how far it spreads. By performing many of these simulations, we get an overview of the likelihood of large outbreaks. This can be summarized by the "effective R number" of a scenario, i.e. the average number of people the initially infected person infects. If this number is smaller than one, we call the situation "controlled". This does not mean that there can't be the occasional large outbreak, but on average the risk for further transmission in the given context is small.

“Personalized medicine” for dairy cattle

Image showing cows Personalized medicine holds great promise for the treatment of complex and multifaceted diseases such as cancer and diabetes these days. In this project I use a large collection of data about dairy cattle, ranging from feed information about farm management and weather to diagnoses, to devise a paradigm framework for the integration of many information streams to predict diseases. In this project I hope to both make dairy farming more animal friendly and efficient and gain new insights for personalized medicine in humans. more...

Image showing the risk profile of a farm for certain dairy cattle diseases such as ketosis and lameness The idea behind the buzzword “personalized medicine” is to integrate all available information about a single patient to devise a prediction for possible disease outcomes and treatments. The information that could be used for such an endeavour includes biomedical data such as bloodwork or incidence of previous diseases but also information about the general way of life of the patient, such as living conditions, demographics and exercise. Dairy cattle make a good paradigm for such an endeavour, as these animals live in a highly controlled and monitored environment that is rich in data sources. On the other hand, data about cows is easier to handle in a proof of concept, as it is not as sensible as health data of humans.

In collaboration with Peter Klimek's group at the CSH I employ a mixed methods approach of random forests to predict diseases such as ketosis and lameness and multivariate regression models to explain the influence of single variables. Next to its use as a paradigm for personalized medicine in humans, this project is of course also of great interest to the dairy cattle industry, as it holds the promise of improving the wellbeing of cows and therefore efficiency of farms.


Emotion dynamics and mental health

Image showing three faces: one happy, one sad and one smug Emotions such as happiness, sadness, anxiety and gratefulness accompany us in our daily life. The duration and order in which we experience these emotions can reveal a great deal of insight about the state of our mental health. Using data of consenting users of the emotional health assistant Youper I work with David Garcia to uncover how emotion dynamics influence depression and anxiety. more...

Using the emotional health assistant app Youper, people can track the emotions they experience and their intensity on a regular basis. Using this data for scientific purposes has great value, since it is a rich data set of thousands of users from different countries, with different demographic backgrounds and detailed descriptions of their emotional state. A change in the frequency of switches between certain emotions can herald the onset of a mental health disorder, whereas other emotions are indicative of an improvement in mental health condition. Insights into the influence of emotion dynamics promise new ways to predict changes in mental health state and improve the measures counsellors or emotional health assistant apps can take.


Pattern formation in salt playa (dissertation)

Image showing salt polygons in a salt desert From fairy circles to patterned ground and columnar joints, natural patterns spontaneously appear in many complex geophysical settings. As part of my research at the MPI for Dynamics and Self-Organization in Lucas Goehring's group I shed light on the origins of polygonally patterned crusts of salt playa and salt pans. These beautifully regular features, approximately a meter in diameter, are found worldwide and are fundamentally important to the transport of salt and dust in arid regions. For my PhD thesis I have combined results from direct field observations, analogue experiments, linear stability theory and numerical simulations to show that the patterns are likely caused by buoyancy-driven convection in the porous soil beneath a salt crust. more...

Image showing a sketch of the convective dynamics in the underground below salt polygons at the surface Salt deserts are not dry - oftentimes the groundwater table reaches up until directly under the salt crust at the top. As their environment is commonly very hot and dry, water constantly evaporates at a high rate through the crust at the surface. As the water evaporates, salt is left behind and accumulates below the surface, forming a layer of saltier and therefore denser and heavier water. For certain conditions, this configuration (heavy salty water on top of light fresh water) becomes unstable and starts convective motion: the salty water sinks down while the fresh water rises to the surface. Convective dynamics are known to form hexagonal patterns and we have shown that the underground below salt patterns shows characteristic salinity distributions indicative of a convective process underneath the pattern.

In our research, we were also able to show that a fast coarsening of the dynamics with time makes the length scale of the expressed patterns independent of the environmental parameters such as soil permeability or the evaporation rate. Lastly, the crust itself interact with the evaporation through the surface that drives the convective motion by inhibiting evaporation at the salt ridges. This helps to "pin" the convection rolls in place and stabilizes the dynamics so intricate salt patterns can grow on the surface.


Biological transport networks

Image showing the venation network of a plant leaf Transport networks are ubiquitous in nature: blood vessels, neurons or veins in plant leaves all transport a quantity or signal that is crucial for an organism to thrive. These networks have evolved over time together with their host organisms. They feature optimized properties such as resilience to damage and transport efficiency. To compare network models with real-life network implementations, the availability of high-quality data is of great importance. This is where my research comes in more...

Image showing the extracted tubular network of Drosophila trachea For my bachelor's thesis, I developed NET, the Network Extraction Tool (code). NET is a freely available, fully Open Source program developed in Python. It can be used to turn digital images of two-dimensional networks into a graph composed of nodes and edges. This creatly compresses the representation of the network while keeping the important information about connections, node positions and edge widths intact.

Using transport networks extracted from high resolution scans of plant leaves, it is possible to classify plants based on the topology and geometry of their transport networks. Next to leaf geometry and size, the network architecture constitutes a new dimension in the phenotypic space of leaves. Evolutionarily younger leaves tend to express more reticulate networks that have a higher resistence to damage at the cost of a higher material need to construct the network. Insights into the properties and evolution of these networks can be used to inform the design of human networks such as the Tokyo subway.

Another application of NET was the extraction of network information from microscopy images of Drosophila trachea. In my master's thesis I analysed the trachea networks of fruit fly larvae and developed metrics to quantify the impact of different gene knockouts on network growth in early developmental stages.

Digitization in research

Together with my colleague Hannah Metzler I developed a course to teach "digitization in research" to doctoral and postdoctoral researchers working at the Ludwig Boltzmann Society. The aim of this two-day block course is to teach early career researchers the basics of a number of digital methods in research, ranging from the finding and management of information, over the management of collaboration and implementation of reproducible research agendas to the communication of research through non-traditional means. All course materials are available under an open license for re-use.

Data Literacy

Together with colleagues from the Centre for Statistics in Göttingen I developed a course to teach "Data Literacy" to entry level students at the University of Göttingen. The aim of the course is to teach students basic knowledge and practical skills to be able to handle, explore and analyse data and make data driven decisions. The course is split into an introduction to Python - the programming language that is used to perform data handling and analysis tasks - and case studies for different disciplines. All course materials are available in German and English under an open license for re-use. We have published our experiences with the implementation of a novel Data Science curriculum in a series of three blog posts and a publication.

Programming in Python

Image showing the logo of the programming language Python

During my time as doctoral researcher at the University of Göttingen and the MPI for Dynamics and Self-Organization, I developed and taught several introductory level courses to programming in Python. I also taught such a programming course specifically "from women for women" which was a great experience. All course materials are available in English and German under an open license for re-use.

Live hack sessions

Image showing the distribution of lengths of Tweets from Donald Trump, Russian trolls and normal Twitter users

Programming is one of my favourite activities. One of the appeals for me is that it is actually a rather easy and forgiving process, since it gives instantaneous feedback if something works and has a large and supportive community that can help with every problem imaginable. Nevertheless, it is often very hard to get people who never wrote a line of code to give it a try, since it oftentimes seems scary and too hard to learn. To solve this problem, I have started to host "live hack sessions" where I, together with a handful of programming novices, sit down for a couple of hours and we solve an easy but hopefully interesting problem together, using Python. The first of these sessions about analysis of Tweet data of Donald Trump, Russian trolls and normal Twitter users is available here and free to be re-used.

Open Science

Image showing the logo of the Open Science movement

When I was in my undergrad and I first learned about the process of publishing science, my mind was blown. I could not understand how researchers payed by tax money create research, which is then taken by big, for-profit publishing companies and hidden behind a paywall. This motivated me to get into Open Science and start doing something about the situation. At first my interest was focused on Open Access, but quickly was joined by my habit of Open Sourcing my code and creating Open Educational Resources. During my PhD and as part of my service as president of the Max Planck PhDnet I got interested in research integrity. These days I think that employing Open Science practices in research workflows is a great tool to foster good science and research integrity.

Executable papers

In the years 2019/20 I was an "Open Knowledge" fellow of the Wikimedia foundation, which allowed me to explore a longstanding fascination of mine more deeply: the executable paper. The executable paper is a scientific publication as a dynamic piece of software that combines text, raw data, and the code used for the analysis, that a reader can interact with and that makes the process of the generation of insights transparent. For me it is a way to remedy the problem of non-transparent (and even sloppy) research and support data availability and transparency of methods. I wrote a series of blogposts about how to create an executable paper and what I learned in the process. The result of my work - an executable version of one of my publications about pattern formation in salt deserts is online and ready to be explored .

Open Source

I strive to make all my code openly accessible on my GitHub profile. Most notably I published the software package small community SEIRX , a software package in Python for the simulation of disease spread in small human communities. During my undergrad, I wrote NET , a software package in Python to extract graphs from high-resolution images of networks. Feel free to open issues in the respective repositories if you find bugs or have trouble re-using something I created!

Open Educational Resources

Similar to code I create, I make teaching resources I create openly accessible and re-usable on my GitHub profile. So far, I have created


Max Planck PhDnet - combating power abuse in academia

Image showing the logo of the Max Planck PhDnet During my time as doctoral researcher at the Max Planck Institute for Dynamics and Self-Organization, I served as representative for the doctoral researcher community for many years. In 2018 , I was spokesperson of the Max Planck PhDnet, an organization that represents the over 5000 doctoral researchers of the Max Planck Society. During my time as spokesperson, several scandals about power abuse in academia shook the Max Planck Society. This motivated me, together with colleagues, to write a white paper about power abuse and conflict resolution in academia and give several interviews about the subject.

N² network of networks - surveying doctoral researchers

Image showing the logo of the N2 network of networks After I finished my PhD in 2019, I keep serving as advisory board member for , the network of representations of doctoral researchers of non-university research organizations in Germany. In my function as advisory board member, I am mostly involved in the conduction and analysis of large-scale surveys about the working conditions of doctoral researchers. In the 2017 survey the survey, for the first time, focused on the mental health of early career researchers. The survey revealed rampant mental health problems of doctoral researchers - as shown in the figure below. In 2018 the report focused on good scientific practice and supervision quality. In 2019, we returned to mental health, this time in connection with mobbing and power abuse. Expect the report to be online soon... Bar diagram showing the number of doctoral researchers in the Max Planck Society that suffer from symtoms related to poor mental health
During your doctoral research, have you had health problems with any of the following conditions? Multiple answers possible. Also included are percentages of respondents giving multiple affirmative answers to symptoms listed.

COST action researcher mental health

As part of my efforts to improve the environment in which research is conducted, I joined the COST action "Researcher Mental Health" as national member for Austria. We will start our activities in the fall 2020.
