Research Interests

I received my Ph.D. in Chemistry from University of Kentucky in 2014 (research advisor: Prof. Anne-Frances Miller). My Ph.D. research projects include:

  1. Use of pre-steady- state and steady-state kinetics, kinetic isotope effect (primary and solvent KIE), numerical simulation and 2D NMR to understand the unusual broad substrate repertoire of nitroreductase.
  2. Integrated computational approach (QM/MM) to the analysis of 15 N and 13 C NMR in active site of flavodoxin.
  3. 19 F NMR study on substrate activation by tuning of pKas in flavin-dependent aromatic hydroxylases.
I joined the Kern lab in 2015 and am currently working on the rapid kinetic of drugs binding to Aurora A kinase and the evolutionary studies on circadian rhythm in cyanobacterium.
