My collaborators include Mary Harrington (Smith College), Jennifer Evans (Marquette University), Alec Davidson (Morehouse School of Medicine in Atlanta), and David K. Welsh (UC San Diego), among others.
If you are an undergraduate interested in getting involved in research involving mathematics and biology, then please contact me! Several students have worked with me on projects analyzing experimental data on jet lag in mice and on modeling the circadian clock in the brain, including two projects that resulted in a published article. No biology background is necessary, just a willingness to learn!
