Professional Experience

Sept. 2008-Present Research Scientist Duke Medical Center, Durham, NC 27710

I am presently serving as a research scientist with the Duke Radiology nuclear medicine group. The focus of our research is in translational stem cell resistance. I am currently working on a number of cancer chemotherapy projects as well as small molecule imaging projects. My duties include synthesis of small molecules and the evaluation of the SAR of these molecules as potential chemotherapeutic agents. It includes optimization of the cellular uptake of selected small and large molecules for tumor cell imaging. This work involves synthesis of small and large molecules (small peptides and antibodies) as well as measuring their cellular uptake in tumor cells. In concert with this work my duties include routinely performing cell assays, cell culture, protein identification and isolation via gel electrophoresis, western blot analysis, silver staining techniques and flowcytometry and others. My responsibilities also include labeling selected molecules with radioisotopes (123I, 124I, 125I, 131I and 18F) via radiosynthetic techniques. Ultimately these compounds are evaluated in mice and humans via PET (positron emission topography) imaging for tumor cells evaluation.

I am also responsible for monitoring exposure to chemical and radioactive materials. This includes Bicron analysis of work sites, Ludlum meters for thyroid analysis and measuring fume hood performance via flow meters.
