Interests and Expertise

(1) I am involved in research on biology education, with a focus on the teaching of introductory biology classes.  My lab investigates the impact of pedagogical practices on student success, with a particular focus on how we can increase the participation of historically underrepresented groups in the sciences.  You can read a news article about this work in EMU Today.

(2) I am interested in how breaks in DNA are repaired by homologous recombination.  In particular, my lab studies the break-induced replication (BIR) pathway, with the goal of understanding how BIR can lead to chromosomal rearrangements. This research uses baker's yeast, Saccharomyces cerevisiae, as a model organism. You can view a short TRUEMU video about this work.
