We are always looking for enthusiastic graduate and undergraduate students to join the lab. Funding for a Master's degree is available to graduate students in the form of teaching assistantships and various fellowships.In addition, opportunities may be available for undergraduate students to do research in the lab for independent study credit or credit towards the University and/or Departmental Honors program. If you are interested in joining the Karatan Lab please contact Ece Karatan.
