Dr. Karamyan joined the Department of Pharmaceutical Sciences in August 2008. He received his Doctor of Pharmacy (Magna cum laude) from the Faculty of Pharmacy, Yerevan State Medical University, Armenia, and Ph.D. in Biology from the Institute of Biochemistry, National Academy of Sciences, Yerevan, Armenia. He continued his postdoctoral training in the laboratory of Dr. Robert C. Speth at the Department of Pharmacology in the School of Pharmacy, University of Mississippi.

Research Interests

Our group is studying the (patho)physiological function of metalloendopeptidase neurolysin (EC in ischemic stroke and neurogenic hypertension.

Additionally, in collaboration with Dr. Thomas Abbruscato we study the role of opioid receptors for neuroprotection in stroke. This project involves (patho)physiological and pharmacological studies to understand alterations of opioid receptors in pathophysiology of stroke, and development of new opioid ligands (in collaboration with medicinal chemists) to target these receptors.
