I am a third-year APPM graduate student currently working with David Bortz on sensitivity and bifurcation analysis of a differential-algebraic equation model for microbial electrolysis cells. I received a B.S. in Mathematical Biology from Harvey Mudd College in 2010 and a M.S. in Mathematics from Claremont Graduate University in 2014.

I am currently working on sensitivity and bifurcation analysis of a differential-algebraic equation model for microbial fuel cells (MFCs) or microbial electrolysis cells (MECs) using data from Dr. Lu in the Ren Lab at CU.

MFCs consist of an anode and a cathode with associated microbial biofilms performing redox reactions. These devices employ microorganisms to oxidize an organic substrate and transfer electrons to the cell anode. Current is generated through an external circuit due to voltage difference between the cell's anode and cathode. MECs go further by utilizing the current to drive a reduction reaction at the cathode, producing valuable products such as hydrogen. Mathematical modeling and sensitivity and bifurcation analysis provide insight into possible performance improvements and enhanced cell design.


I am a TA for Differential Equations with Linear Algebra (APPM 2360) in Spring 2018.

In the past, I was an instructor for Calculus 3 for Engineers (APPM 2350) in summer 2017. I have also been a TA for APPM 2350 and APPM 2360 several times as well as a coordinator for Differential Equations Lab (APPM 2460) and Calculus 3 Lab (APPM 2450).
