Research opportunities for Undergraduates


Before you join our research group, you need to take Chemistry/Physics 328. The next offering is Fall 2019. The pre-requisites are calculus II and one chemistry or physics class. In addition to signing up for the class, you should also send me an email expressing your interest in joining our group at the end of the class and confirm it near the end of the class so we can begin to choose your individual project. After the class, you can sign up for research in 2 credit intervals. Each two credits represents a full afternoon of computer and/or paper and pencil work plus time outside of that for writing midterm and final papers. Summer opportunities require at least one independent study semester starting on your project after Chemistry/Physics 328.
