Jan Karbowski is currently Associate Professor in the Mathematics Department at the University of Warsaw, but his main scientific interests are in Systems and Theoretical Neurobiology. He obtained his PhD in Condensed Matter Physics in 1996, after which he made a transition to Neuroscience at Boston University during Fulbright Fellowship. He is glad that there has been a growing number of people deciding about jobs and grants who appreciate interdisciplinary work. Thanks to those few people he could work and conduct research with in the "exotic" field of Computational Neuroscience at various departments and institutions in the USA: Boston University (Physics nad Math Depts.), University of Pittsburgh (Math Dept.), and Caltech (Biology Dept.). His current interests include the biophysics of learning and memory in neural systems, evolutionary scaling laws in the brain, and locomotory control in neural circuits of C. elegans. He approaches these problems using powerful methods of Theoretical Physics and Applied Mathematics. Privately, he likes to play football with his two sons, and to talk about everything with his lovely wife Aneta.
