PROF. ADAM BOBROWSKI is a well-known specialist in the theory of semigroups of operators and mathematical biology. He has authored and co-authored 36 scientific papers in leading journals including Journal of Functional Analysis, Journal of Evolution Equations, Semigroup Forum, Studia Mathematica, Mathematical Biosciences, Theoretical Population Biology and Journal of Mathematical Biology. He is also the author of the successful book [9]. Along with papers in pure mathematics, he has published extensively on population genetics models involving drift and mutations, and on convergence of operator semigroups involved in various models of mathematical biology, including those of gene expression, gene regulation, and age-structured and space-structured populations.
