My research program will focus on studying the molecular pharmacology of G Protein Coupled Receptors (GPCRs; focusing mainly on the Proteinase Activated Receptor family) and Transient Receptor Potential (TRP) ion channels. We use various techniques to understand cell-signaling responses to GPCRs and TRP channel activation at the molecular level and in vivo. These studies have relevance to various human diseases including cancer, cardiovascular diseases and inflammatory diseases such as colitis and asthma..

Techniques in the Lab: The lab will take a multidisciplinary approach and studies will range from understanding receptor/channel function at the molecular level to in vivo models of disease.

  1. Molecular cloning
  2. Calcium signaling/imaging
  3. BRET/FRET, designing and synthesizing novel biosensors
  4. Confocal, TIRF microscopy
  5. PCR, Western Blot, Immunostaining, ELISA
  6. Platelet signaling assays
  7. Vascular tissue assays
  8. Animals models of inflammation
