Research interests:

Since the start of my studies I was fascinated by the self-organization of living systems: how do molecules interact with each other to form complex, living systems? During my time at the Goethe University Frankfurt and the Free University Berlin I was interested in the very details of biological processes – what are the chemistry and physics of those processes? I considered to do a PhD in Quantum Biology.

But after gaining experience in biophysical modelling and structural biology, my attention turned from the modelling of molecules to the modelling of systems. In the groups of Edda Klipp at the Humboldt University and Joerg Stelling at the ETH Zurich, I became fascinated by the perspective of systems theory and whether it can characterize biological systems (or can’t – which is probably even more interesting).

In the spring of 2015, I joined the project on the interferon lambda signalling pathway. This pathway received a lot of attention in recent years, because several SNPs in the lambda 3 gene were found to interfere with the efficacy of Hepatitis C treatment and influenza vaccination in immunocompromised patients (Egli et al., 2014, Egli et al., 2015). The reason for this and its mechanism are yet to be understood.

In my PhD project, I use both theoretical and experimental approaches to address our hypotheses on how interferon lambda SNPs impact the lambda signaling pathway and how this results in a modulated vaccine response. The goal is to develop a mathematical model that describes the impact of interferon lambda genotypes on lambda signalling and antibody production after an influenza vaccination. An advance in the understanding of these processes will help to develop improved vaccination strategies for immunocompromised patients – for instance to the benefit of post-transplantation patients, which are subject to high risk of influenza-related complications.

Keywords: Interferon lambda signalling, antibody response, single nucleotide polymorphisms, SNPs, ordinary differential equation models, ODEs, nonlinear mixed effects models, NLME, flow cytometry.
