Dr. Sterne-Marr earned a B.S. in Biology from UCLA in 1983 and a Ph.D. in Biochemistry from UC Berkeley in 1989.  She carried out post-doctoral work on an in vitro assay to measure nuclear protein import with Dr. Larry Gerace at Scripps Research Institute and cancer research at Merck, Sharp and Dohme Research Laboratories before initiating studies on cell signaling with Dr. Jeffrey Benovic at Thomas Jefferson University.  She joined the Siena faculty in 1995 where she teaches Biochemistry and Molecular Genetics and leads a group of undergraduate researchers in the study of the regulation G protein-coupled receptor (GPCR) signaling. The group focuses on the action of GPCR kinase 2 (GRK2) in regulating hormone and neurotransmitter-induced cell signaling. The role of GRK2 is assessed using mutagenesis, in vitro kinase assays, cell culture, intact cell phosphorylation assays, and BRET-based receptor recruitment assays. In 2016, she joined the Genomics Education Partnership (GEP), and in collaboration with Dr. Tom Giarla, directs students in a course-based undergraduate research project in Drosophila genomics. Another GEP project will use course-based undergraduate research experience (CURE) to carry out a proteomic analysis of Drosophila-parasitoid wasp interaction with Dr. Nate Mortimer of Illinois State University. She is also a member of Bridging Research and Education (BREW) and hopes to develop a CURE using yeast as an experimental system.

Current Research

Promoting Undergraduate Research

I am committed to developing career scientists and providing opportunities for undergraduate research. With the assistance of three National Science Foundation research grants (1997-2014), I have mentored >100 research students in the last twenty-fivea years.  In addition, in collaboration with other Siena science faculty, I have secured funding to support undergraduate research training (NSF STEM/Tech Valley Scholars and Clare Booth Luce Fellowships) and to promote the participation of women and under-represented individuals in science, technology, engineering and mathematics. Twenty-three former undergraduate students are co-authors on papers from my lab published in the Journal of Biological Chemistry, Biochemistry, and Methods in Enzymology.
