04/2011-7/2012  Case Report Research—Department of Plastic Surgery—Detroit Medical Center.Principle Investigator: Chenicheri Balakrishnan M.D.
Conducting background research for a case report to be submitted for publication on burn microsomia repair using commissurotomy with a single mucosal advancement flap.
2/2009–5/2012 Research Associate with the Department of Cardiovascular Surgery — Children’s Hospital of Michigan.
Principle Investigator: Henry Walters III M.D.

Conduct research on Cerebral Near Infra-Red Spectroscopy and its effects on acute and long-term outcomes for pediatric patients undergoing cardiac surgery with bypass.  I also conduct research on rare congenital cardiac heart defects including aortic-right atrial tunnel and aortic-left atrial tunnel.
2/2009–8/2010  Clinical Researcher with the Heart and Vascular Physicians-Detroit Medical Center.  Principle Investigators: Taman Muhammad M.D. & Mahir Elder M.D.
Researched the effectiveness of percutaneous stenting therapies versus coronary artery bypass grafting surgery on patients suffering from severe (>50 % occlusion) left main coronary artery occlusion.
3/2007–9/2007  Thesis Research at the UMDNJ-Graduate School of Biomedical Sciences.
Principle Investigator: Venkat Venkataraamen Ph.D.

Researched the effect of inflammation on the blood brain barrier.  Research was directed at demonstrating that chronic and acute inflammation increases the permeability of the blood brain barrier thus reducing the selectivity of transport mechanisms and leading to neuronal dysfunction.  In order to demonstrate this, I utilized in vivo and in vitro experiments and tested the effects of known inflammatory agents.
