I’m interested in the possible forms that organisms in a population can take on as the population evolves. Conceptually we organize these forms (or phenotypes) according to their fitness and mutational distance from one another on a fitness landscape. I’m working towards an understanding of the physiological traits and interactions that make up a model fitness landscape: the central carbon metabolism of Methylobacterium extorquens.

Not Research

Python group

I organize a group of my fellow graduate students for an informal introduction to computer programing. I write some of my own material but also use material from Software Carpentry.

Data and source code

I host the source code and data for all my research on an online git repository.


Society for Advancement of Chicanos and Native Americans in Science

I have attended the SACNAS National Conference every year since 2012 representing my department, and encouraging minority students to apply.
