Vadim Y. Rygalov, Ph.D. in Physics & Mathematics, is a biophysicist and has worked in the area of Closed Ecological Systems (CES) studies and Bio-Regenerative Life Support since 1979 after his graduation with MS in Ecological Biophysics from Krasnoyarsk State University (KSU), Central Siberia, USSR. He is also an Associate Professor, UND John D. Odegard School of Aero-Space Sciences, Space Studies Department Consultant for KSC NASA Space Life Sciences Lab. During his education in KSU in 1969 – 1977 he was participating in a series of pilot researches related to investigation of human physiological and psychological limits. He received his Ph.D. for work ‘Systems Analysis of Environment/Organism Optimal Interaction: Sea Macro-Algae Growth and Development’ in 1987 from Institute of Biophysics, Siberian Branch of the Russian Academy of Sciences (Krasnoyarsk, USSR) and Pacific Research Institute of Oceanography & Fishery Sciences Ministry of Fishery Industry USSR (Vladivostok, USSR). His current interests involve studies of closed ecological system functioning and their applications for human life support in space; limits of stable human/environment interactions; human factor limits & control algorithms in high risk operations, etc. He is also interested in applications of developed technologies for human life support in unusual (primarily extreme) environments: years 1999 – 2004 he spent at the Space Life Sciences Lab KSC NASA working with Low Pressure Space Greenhouse prototypes.
