Current Research Interests

Dr. Cohen has three main areas of research in her laboratory. She has studied the mechanism by which nuclear-encoded translational activators regulate the translation of chloroplast-encoded photosynthetic mRNAs in the unicellular green alga Chlamydomonas reinhardtii for 24 years. She also has established collaborations within the Department of Biological Science to investigate the population genetics of the endangered Santa Ana River Woolly Star (Eriastrum densifolium ssp. sanctorum) using allozyme analysis and RAPDs and identify the roles of different hosts play in the spread the bacterium that causes plague (Yersinia pestis) in prairie dog colonies, using PCR-based analyses and external collaborations to use Chlamydomonas as a bioreactor for the production of eukaryotic proteins. Dr. Cohen is the Director of the NIH-funded MARC (Maximizing Access to Research Careers Program), which provides students with a comprehensive experience that leads to acceptance into high-quality PhD programs and a research career in biomedical or behavioral science.
