I come from Northern Poland from a city of Slupsk. In 2003 I earned Masters degree in Physics in the field of theoretical Biophysics at the Warsaw University. I spent last year of my Masters studies at Free University (VU) Amsterdam as part of Socrates/Erasmus programme. At VU, I worked on a particle-based algorithm for spatial-stochastic simulations of biochemical networks (link to thesis). Further on, I pursued my PhD studies at the Centre for Mathematics & Computer Science (CWI) in Amsterdam. The topic of my PhD thesis was a theoretical and computational study of noise in gene expression and cell signaling (link to thesis). After my time in Amsterdam I moved to the Institute of Theoretical Biology at Humboldt University in Berlin and since August 2010 I started as a post-doc here at SBI. My major line of research revolves around theoretical and experimental investigations of cellular processes that contribute to cell-to-cell heterogeneity involved in drug resistance of cancer cells.
