Current Research Projects

  • Translational studies of human neuronal nicotinic receptor genes associated with alcohol and tobacco behaviors.

    • Identification of rare, novel SNPs.

    • Dense SNP mapping in large human samples.

    • In vitro functional characterization of human SNPs.

    • Behavioral testing of nAChR knock-out mice.

  • Studies of the effects of voluntary wheel running on alcohol consumption in mice using a genetics approach.

Opportunities for Undergraduates

  • Our lab is currently looking for an undergraduate to assist with ongoing mouse behavioral testing.
  • The requirements for undergraduate students who want a research experience in our laboratory are:

    • A major in Integrative Physiology.
    • Either have completed or be concurrently enrolled in IPHY 2800 Introduction to Statistics.
    • Enroll in Independent Study (IPHY 4860) for 8-10 hours/week for at least one semester.
