Keith Geiszler has worked in the Geosciences Group since 2002. Prior to that, he worked in the Toxicology group in LSL II since 1996, and worked in an environmental lab in Gainesville Florida upon graduation from college in Florida. Keith moved to the Tri Cities from Florida with his wife and son in 1996. Since joining the Geosciences Group, Keith has been a part of the environmental services lab, from operating the ICP-MS for a wide variety of projects, to overseeing the trace metals group and now co- manages the ESL. Keith has also been active with the tank waste and waste form testing applications, such as characterization of the tank waste, single-pass flow through, and pressurized unsaturated flow reactions. Most recently, Keith has become a key member of the Radiation Portal Project calibration team, which provides a great change of pace as well as lots of travel to domestic seaports and border crossings. In his spare time, Keith participates in the Battelle co-ed softball league as well as the Pasco Men’s softball league. He catches up as often as he can with his son, Jordan, who flies planes in college as he studies to become a commercial pilot. Keith also travels extensively with his wife, Nikki. He can often be found watching or attending Oakland Raider football games, his other passion next to his wife and son!
