Igor Kutnyakov worked 12 years as research scientist at the Scientific Production Association (SPA) “Typhoon,” in Obninsk, Russia. He joined Battelle in 1998 as a visiting scientist. He is a Senior Technician in the Geosciences Group currently, a position he has held since being reclassified from the position of Science and Engineering Associate in 2003. I.Kutnyakov has more than 28 years of experience studying of radionuclide behavior in soil, subsoil, bottom sediment (migration in soil, contaminated soil leaching, transport phenomena, and sorption-desorption processes). Since 2011 he has worked mainly in other groups, supporting such projects as Carbon capture process for post-combustion emissions cleanup, using new generation of CO2 –Binding Organic Liquid(s), CO2-BOL., Metal-organic frameworks (MOFs) synthesis, Fast pyrolysis and bio-oil production, and some others.
