My interests lie at the interface between mathematical and life sciences. I try to formulate interesting questions in areas of biology, medical and social sciences and linguistics, in the language of mathematics. Then I try to find answers to these questions by developing applied math techniques. The main unifying topic is evolution. The general areas of application are:

• Modeling of cancer
• Evolution of resistance to drug treatment
• Stem cell dynamics
• Tumor heterogeneity, Genetic instability
• Other topics in mathematical biology
• Virus dynamics
• Signaling networks
• Alzheimer's disease
• Mathematical modeling of complex social phenomena
• Learning and evolution of language
• Historical dynamics
• Color categorization
