    • Research Scientist
      Jan 2002 - Oct 2009 · 7 yrs 10 mos

      Moved projects into discovery and pre-clinical status by providing evidence for direct binding of small molecules to protein targets. Worked closely with chemists and biologists on oncology, neuroscience, cardiovascular, tissue repair, and infectious disease targets. Performed enzymological / biophysical characterization of proteins for target validation and assay development of early-phase projects. Generated, adapted, and transferred assays to high-throughput screening group, working closely with them to meet process optimization and quality goals. Ran assays in low-to-medium-throughput to measure inhibitor potency, specificity, and test inhibition mechanism. Used automated liquid-handling systems (JANUS) to generate 384-well plates for fluorescence, TR-FRET, and absorbance assays. Responsible for investigating and implementing new technologies for hit-to-lead activities. Prepared and presented talks and posters within the Discovery organization and externally.
