A presentation of our newly employed colleagues.

## Victor Ahlquist

### PhD student at the Division of Algebra and Geometry

I am a PhD student in analytic number theory. Specifically, I am interested in the low-lying zeros of families of L-functions.

Start date: 1 June, 2023

## Nina Gantert

### Jubilee professor at the division of Analysis and Probability Theory

I am working in probability theory, in particular on stochastic processes, random media and large deviations. My research topics include the use of random walks to model transport in disordered media, and interacting particle systems as for instance the exclusion process.

I am also interested in applications of probability theory to Physics and Biology.

## Georg Huppertz

### PhD student at the Division of Analysis and Probability Theory

My research will revolve around C*-algebras, in particular Cuntz semigroups. There exist several invariants to distinguish C*-algebras. The Cuntz semigroup is one of them. It has a couple of benefits compared to K-theory. The complex numbers, the Jiang-Su algebra and the suspension of the Calkin algebra, all have the same K_0- and K_1-groups, whereas each of them has a different Cuntz semigroup. Besides, the Cuntz semigroups preserves the closed ideal structure of the C*-algebra, something that K-theory does not in general.

I will work under supervision of Hannes Thiel and Christian Johansson. I hold a MSc-degree from the Radboud University in Nijmegen and a BSc-degree from Leiden University, both in the Netherlands. I wrote my master thesis about the Universal Coefficient Theorem for C*-algebras.

Start date: 1 May, 2023

## Elin Bergström

### Study administrator, Operations Support

will work as an administrator within operations support, mainly with study administration such as examination administration, student office work and results reporting. Previously, I worked as a study administrator at the Department of Chemistry and Molecular Biology at the University of Gothenburg.

Start date: 11 April, 2023

## Eszter Lakatos

### Assistant professor at the Division of Applied Mathematics and Statistics

I am joining the department in a Health Engineering Area of Advance position. My research focuses on developing mathematical models and bioinformatic methods to understand how cancers adapt to their environment.

In this position, I will work on stochastic models of tumour growth and new methods for analysing cancer sequencing data. I will apply these methods to study the cancer-immune interaction and cancer dynamics during therapy.

Start date: 1 April, 2023

## Jan Gerken

### Assistant professor at the Division of Algebra and Geometry

I’m starting a new WASP-funded group at the division of Algebra and Geometry in the area of mathematical foundations of deep learning, in particular geometric deep learning, as assistant professor. I’ve previously been a postdoc at Mathematical Sciences and am happy to be back!

With my group, I will work on equivariant- and wide neural networks. On the theory side, our work is heavily inspired by physics, borrowing from concepts like gauge theory and quantum field theory. On the practical side, we are working on applications in condensed matter physics, autonomous driving, quantum chemistry and want to expand into pure math applications as well.

Start date: 1 March, 2023

## Maria Teresa Moncatar

### HR-partner, Operations Support

I am a substitute HR partner who works strategically and operationally with HR issues through guidance and support to managers at the department as well as works with Chalmers' overall HR issues. I have performed in the same field of work since 2013 at the University of Gothenburg.

Start date: 1 March, 2023

## Hampus Linander

### Researcher at the Division of Algebra and Geometry

Start date: 1 February, 2023

## Arpitha Prasad Bharathi

### Postdoc at the Division of Applied Mathematics and Statistics

Start date: 18 January, 2023

My research interests broadly include optimisation and graph theory. I have a PhD in Theoretical Computer Science from Switzerland and my thesis is about combinatorial polynomial ideal membership problems and how they are useful in optimisation. I have done some work in algorithm complexity, structural graph theory and graph colouring. I am now foraying into artificial Intelligence and its uses in mathematical optimisation, in a research project headed by Axel Ringh and funded by WASP. Some minor projects I’ve worked on include image processing for computer vision and simulation of evolution of cooperation in ecological sciences.

## Isac Boström

### PhD student at the Division of Analysis and Probability Theory

Start date: 9 January, 2023

## Erik Karlsson Nordling

### PhD student at the Division of Applied Mathematics and Statistics

Start date: 1 January, 2023

My main interest is algorithms and machine learning for decision making, both in single-agent and multi-agent systems. The research project which I am working on concerns the development of a model for decision support in health care. The model will be based on Markov Decision Processes (MDPs) and reinforcement learning (RL). The project is part of the WASP programme and is supervised by Marina Axelson-Fisk.

I took my master's degree in Complex Adaptive Systems at Chalmers in December 2022. I also have a bachelor’s degree in Engineering Mathematics from Chalmers.

## Adam Malik

### Postdoc at the Division of Applied Mathematics and Statistics

Start date: 1 January, 2023

My research is in mathematical biology, mainly concerning mathematical models of the growth of cancer tumors. Most recently I have developed a mathematical model of tumors growing in the brain of mice, based on anatomical features of the brain. I am also interested in how AI and machine learning techniques can be used in mathematical biology in new ways.

During my Postdoc at MV I will be focusing more on AI and machine learning as part of Rebecka Jörnsten’s research group.

## Hannes Thiel

### Professor at the Division of Analysis and Probability Theory

Start date: 1 January, 2023

I work on algebraic aspects in functional and harmonic analysis. My main research interests are the structure and classification theory of C*-algebras and rigidity phenomena for representations of groups on Banach spaces.

I will be a Wallenberg Academy Fellow at Chalmers University of Technology.
