Biography

Dr. Ralf Sudowe received a M.S. in Chemistry (1995) and a Ph.D. in Nuclear Chemistry (1999) from the Philipps-University Marburg in Germany. He spent two years as Visiting Postdoctoral Fellow in the Nuclear Science Division at Lawrence Berkeley National Laboratory (1999 – 2001) and then became a Staff Scientist in the Nuclear Science and Chemical Sciences Division at LBNL (2001 – 2006).  From 2006 to 2016, Dr. Sudowe was a faculty member in the Department of Health Physics & Diagnostic Sciences at University of Nevada Las Vegas, where he held the titles of Assistant Professor (2006 – 2012) and Associate Professor (2012 – 2016).  He joined the faculty of the Department of Environmental & Radiological Health Sciences at Colorado State University in the summer of 2016.

Dr. Sudowe has extensive experience in the area of nuclear and radiochemistry, in particular in the development of radioanalytical separations for actinide and transactinide elements as well as fission products.  His research focuses on the development and optimization of radioanalytical methods for environmental monitoring, nuclear forensics and safeguards as well as emergency response. In addition he studies the chemical and nuclear properties of transactinide elements and is involved in target preparation and cross section measurements for stockpile stewardship science.  Dr. Sudowe is a member of the American Chemical Society, the American Nuclear Society and the Health Physics Society.
