Dr. Dooley uses her training in combinatorial libraries and fluorescent imaging to research new methods for pain relief, addiction and food regulation, and investigates cells' response to stresses which may lead to a better understanding of pain management, chronic pain, addiction, Parkinson's and Alzheimer's.

Dr. Colette Dooley completed her undergraduate studies with honors in 1987 and earned her Masters of Science degree in Zoology ("Identification of binding sites for Atrial Natriuretic Peptide on Gills of Salmonids"), both at the University College Dublin, Ireland. She joined the Torrey Pines Institute in 1990 as a Research Assistant and her research included developing high throughput radioreceptor screening assays and modifying existing opioid receptor assays for screening with combinatorial libraries. In 1994, she was named a Senior Scientist at TPIMS and supervised five research technicians on projects involving the use of mixture based combinatorial libraries in radioreceptor assays for opioid ligands, melanocortin ligands, melanin concentrating hormone, substance P and orphanin FQ and is now the lead author of a study on compounds that are in clinical trials. These research projects were funded by either NIH or commercial enterprises. In 2000, she pursued her Ph.D. in the Department of Chemistry and Biochemistry at the University of California in San Diego. She trained with Roger Tsien of UCSD who is renowned for discovering calcium sensitive fluorescent dyes and optimizing Green Fluorescent Protein in 1994. She achieved her Ph.D. in Chemistry, with her thesis entitled, "Green Fluorescent Protein Based Indicators of Dynamic Redox Changes and Reactive Oxygen Species" in 2006. Dr. Dooley rejoined TPIMS in their new endeavor in Florida as an Assistant Member.
