Research Opportunity available for Students

Feel free to send me an email if you are interested.

If you are interested in working with me at the University of Michigan, please apply for the REU (Spring/Summer) or Log(M) (Fall, Winter) at the University of Michigan.

REU applications are welcome from students from all schools. You are paid a stipend of approximately $4,800 for 8 weeks during the summer to work with us in Ann Arbor. NSF-funded participants must be U.S. citizens or permanent residents. We may have a limited amount of funding for non-resident non-citizens.

Please click here for more information about the REU program in general as well as other sites.

If you are interested in seeing some of the available research projects, you may do so by clicking here.

Currently, I have one graduate student, three undergrad students from UofM for Log(M), one REU student from Cornell University, one REU from Rice University, and one from the University of Illinois at Urbana Champaign. Please let me know if you are interested in joining our team!
