Research Interests

Bystriansky is an environmental physiologist who takes a comparative approach to understanding how animals are adapted to survive in harsh environments. His research program is mainly focused on what limits most fish species to live in either fresh or salt water, while others can tolerate wide ranges of environmental salinity. To do so, Bystriansky studies the role and regulation of the sodium pump in osmoregulation and how the expression of different isoforms of this protein may limit the salinity tolerance of fish. His research focuses on several euryhaline fish groups including the anadromous Salmonids, the catadromous eels, and euryhaline stickleback and killifish.
