Current Projects:

Projects in the lab are focused on understanding the enzyme mechanism and biological function of tRNA processing enzymes, including a unique 3'-5' polymerase that catalyzes diverse tRNA maintenance and repair reactions and an m1G9 methyltransferase with unexpected substrate specificity and multiple roles in higher eukaryotes, including humans.  We use enzyme kinetics, structural, and genetic approaches to answer these questions.
