Keeney earned her B.S. in biochemistry from The Pennsylvania State University in 1985 and
her Ph.D. in immunology from Washington University of St. Louis in 1990. Prior to her
arrival at Juniata in 1994, she was a postdoctoral fellow in the Department of Genetics
and Molecular Biology at the Johns Hopkins University School of Medicine. In 1991, she was
awarded a postdoctoral fellowship from the American Cancer Society.
As a four-year college, Juniata has no masters or Ph.D. programs. Thus, research in my laboratory is conducted exclusively by undergraduate students, with a strong emphasis on integration of teaching and research. Students can become involved in the research process as early as the first year. Grant funded summer research fellowships allow our students to spend summers fully immersed in their research projects. Our research focuses on the molecular mechanisms of transposition of the Ty retroelements of the yeast Saccharomyces cerevisiae (bakers yeast). Our main focus involves studying the transposition process by isolation of host genes involved in high temperature transposition. A second project involves deciphering the mechanism of priming of reverse transcription, through mutational analysis of the primer tRNA and Ty1.
