Research Interests

The health of our planet, and our own, is shaped by microbial communities that harbor hundreds of coexisting "species". Their study is a very active and exciting field: an enormous amount of data is now available, with more being collected every day, and yet we still know very little about these microbial ecosystems. The challenge is not just experimental and technological: it is also theoretical. How should we be describing these systems, when even the basic concepts of "species" and "fitness" become ill-defined? How do we link composition to function? And more generally, what if our macroscopic intuition about ecology and evolution is simply wrong at the scale of microbial life? To make progress, data is essential, but not sufficient: we need both theory and theory-driven experiments.

Prof. Tikhonov's research lies at the intersection of statistical physics, bioinformatics and microbial ecology.

Other interests include genetic regulatory networks, developmental biology and information theory.
