Alumna Daphne Guinn (Toxicology, 2011) was awarded a Ph.D. in Biomedical Sciences from Ohio State University earlier this month. Her Ph.D. dissertation research was focused on chronic lymphocytic leukemia. She was specifically concerned with how alterations in Bruton’s tyrosine kinase affect the transcriptional profile and phenotype of chronic lymphocytic leukemia cells. She has contributed to three publications thus far based on her research. Following graduation, Daphne has been offered a postdoctoral fellowship at Georgetown University as a PRSM-PhRMA Fellow in Regulatory Science. Daphne hopes to pursue a career in the clinical regulatory field in the pharmaceutical industry or government.
