System-Immunologie
Das Immunsystem mit Hilfe der Mathematik zu verstehen, das ist das Ziel der Abteilung System Immunologie. Mathematische Modelle sollen helfen, Krankheiten schneller und besser zu erforschen, die mit dem Immunsystem in Verbindung stehen. Erfahren Sie hier, wie die Forscher die Mathematik nutzen, um chronisch-entzündliche Krankheiten, die Steuerung von speziell auf Erreger angepasste Immunantworten sowie die Wechselwirkung des Nerven-, des endokrinen und des Immunsystems zu untersuchen.

Lebenslauf
It was a sunny morning of 1978 when a tremendous thing struck Earth... me! This little guy (hmm...not really) was born in Thessaloniki, the second biggest city in Greece. Soon after, we changed a couple of cities and I landed at my second hometown, Serres, where I spent my school years. Finishing the school in 1996, Thessaloniki was ready to accept me for my university studies in the Mathematics department of Aristotle University of Thessaloniki. In 2001, after five incredible years, I left Greece to enroll in the program of Industrial Mathematics (Technomathematik) in TU Kaiserslautern. I stayed for 1,5 years, and the road brought to the amazing capital of Germany, Berlin. There I spent almost one year doing my master thesis at the ITB under the supervision Prof. H. Herzel. Finally, in 2004, I received a Marie Curie scholarship to accomplish my PhD thesis in the IMC group of A. Deutsch, at TU Dresden. In 2009, Europe was fed up with me and I found myself playing the cowboy in Texas, with my ranch at UT at Houston. Next year (2010), in an attempt to find Heisenberg (from Breaking Bad), I found myself in Albuquerque at University of New Mexico. While searching I ended up again in Germany (2011), and in particular in Brunswick, at the Helmholtz Institute for Infection Research (HZI) collaborating with M. Meyer-Hermann. Although I was trying to keep myself away, the sirens of Dresden called me back and from now on (2013), I will be a group leader in the new excellence cluster of cfAED. Finally, I am back in HZI.
Research
My research is focused on the understanding of cell decision-making and its impact on multicellular systems. Decisions of interacting cells allow for the emergence of higher order organizational structures, such as immune responses, bacteria colonies or tumors. At the same time, the new emergent structures exert selective forces on the cell phenotype decision dynamics. With the aim of understanding the mechanistic connection between single cell decision-making and associated multicellular dynamics, I develop multiscale mathematical models. My main focus is on understanding the cell decision-making in multicellular systems via mathematical modeling.
