Research:

I am interested in how circadian rhythms of gene expression in the brain affect memory and other cognitive processes. Further, I am examining the effects of a mouse model of non-metastatic breast cancer on a variety of rhythmic physiological processes, as well as the effects of chemotherapy on these rhythms. To answer these questions, I utilize a variety of molecular and behavioral techniques to quantify 24-hour rhythms throughout the body.
