    T. Sean Vasaitis, Ph.D., M.S. EHS
    Associate Professor and Interim Assistant Dean for Student Affairs


    Dr. Vasaitis completed his doctoral work in Molecular Pharmacology and Experimental Therapeutics at the University of Maryland School of Medicine in 2007.  He holds a masters degree in Exercise and Health Science from Miami University, Ohio and a bachelors degree in Biology from the University of Maryland, Eastern Shore.

    Prior to his appointment at the UMES School of pharmacy, Dr. Vasaitis was a research fellow with Dr. Angela Brodie and Dr. Vincent Njar at the University of Maryland, Baltimore (UMB).  At UMB he was involved in the development of novel inhibitors of androgen action for the treatment of prostate cancer.  He also is involved in clinical research in the Geriatric Research, Education and Clinical Center at the Baltimore Veterans Affairs Medical Center investigating the mechanisms by which exercise, vitamin D and complementary therapeutics affect metabolic function.    

    Dr. Vasaitis’ research goals follow the overarching concept of integrating Western approaches to medicine and pharmacological therapy with evidence-based complementary medicine to further a holistic approach to disease treatment.  In addition to his research in novel drug development and metabolic function, he has taught taijiquan (tai chi) to patients with stroke, cancer, multiple sclerosis, cardiovascular disease and diabetes as part of studies with Johns Hopkins Prohealth, the University of Maryland School of Medicine, and within his own business practice.
