John Ejnik profile picture

Dr. Ejnik earned his PhD in biochemistry from the University of Wisconsin-Milwaukee in 1991. His dissertation topic was entitled “Formation and Reactivity of Metallothionein in Metal and Ligand Substitution Reactions”. For the next six years he served as an officer for the United States Navy. His service with the Navy includes being a Radiobiology Research Chemist at the Armed Forces Radiobiology Research Institute in Bethesda, Maryland; a Production Manager at the Navy Drug Screening Laboratory in Great Lakes, Illinois; and a Research Chemist at the Armed Forces Institute of Pathology in Washington DC. Dr. Ejnik then joined Northern Michigan University where he taught analytical, instrumental, general, forensic, and biochemical courses for five years. He then joined the University of Wisconsin-Whitewater where he continues to teach analytical chemistry courses, serves as program coordinator for the Integrated Science and Business program and serves as the Chair for the Chemistry Department.

               Dr. Ejnik’s research interest includes analytical chemistry involving trace metal analysis in a wide variety of fields. Primary research is done in the area of biological inorganic chemistry involving transition metals, heavy metals and metal speciation interactions with proteins and small organic molecules. However, research also includes trace metal analysis in the fields of geology, environmental science, forensic science and toxicology.
