Major Areas of Research Interest: 
  • Molecular cloning of G-protein coupled receptors: esp. "2-adrenergic, serotonin, PAF and prostaglandin subtypes
  • Functional expression of cloned receptors in mammalian cell lines to study receptor/effector coupling and structure/activity relationships3. Use of recombinant DNA techniques to study receptor structure: such as construction and expression of chimeric receptors and fusion proteins
  • Preparation of anti-receptor antibodies to study receptor structure and localization
