Academic Background: 

  • Whitney Professor of Biochemistry, Butler University (2016 - Present)
  • Professor of Chemistry and Biochemistry, Butler University (2021 - Present); Associate Professor of Chemistry, Butler University (2015 - 2020); Assistant Professor of Chemistry,  Butler University (2009 - 2014)
  • Postdoctoral Research Fellow (American Cancer Society Fellow and HHMI Research Associate), Harvard University (2007 - 2009). Research Advisor: Dr. Erin K. O'Shea
  • PhD Biochemistry, University of Wisconsin-Madison (2007). Research Advisor: Dr. Ronald T. Raines.  

Research Interests:

My laboratory is globally interested in serine hydrolases: their structure, function, enzymatic activity, biological activity, and therapeutic potential. Specifically, we are interested in: 

  1. Serine hydrolases from Mycobacterium tuberculosis: role in the basic biology, diagnosis, and treatment of tuberculosis.
  2. Protein palmitoylation and dynamic control by thioesterases.
  3. Medically relevant bacterial and human serine hydrolases.

I have an active undergraduate research program with 4 - 10 undergraduate students per semester and 2 - 4 undergraduate students during summer research. Summer research students obtain funding through the Butler Summer Institute (BSI), through internal funding from Butler, and through coverage from external grants from the NSF and NIH. I have mentored students with majors from chemistry to biology to pharmacy and starting from first year students to fourth year students. Students working in my laboratory have continued onto top graduate school programs in biochemistry, molecular biology, chemistry, genetics, and inorganic chemistry, onto top medical and dental schools, and into different chemical and business industry positions.
