Lab Members

Postdoctoral and Visiting Researchers

Scott Mulrooney Scott Mulrooney received his Ph.D. from the Hausinger lab at MSU in 1990 and then worked as a postdoctoral fellow and lecturer at the University of Michigan, where his research focused on structure/function studies of flavin-containing enzymes. Returning to MSU in 1999, Scott carried out metal binding studies on the UreE metallochaperone for urease activation, characterized the DNA-binding and enzymatic properties of the AidB flavoprotein, and further characterized the UreG urease-activating GTPase. Scott still attends lab meetings when he can to stay connected to research, but his time is filled by duties as the MMG Director of Undergraduate Studies.

Graduate Students

Joel RankinJoel Rankin graduated from Washington University in 2013 with a Bachelor of Arts in Biology. His undergraduate research project involved studying the pathway used to covalently attach heme to cytochrome c in plant mitochondria and many bacteria. Joel’s current project focuses on the mechanism of lactate racemase and the pathway for biosynthesis of its Ni-pincer cofactor.

CaitlynCaitlyn (VanGelderen) Herr graduated from Kalamazoo College majoring in Biology and Chemistry. Her current project focuses on CsiD, an Fe(II)/2-oxoglutarate dioxygenase that hydroxylates glutaric acid. She also works with an Fe(II)/2-oxoglutarate-dependent ethylene-forming enzyme.
