    Dr. Deborah Korenstein is a general internist, clinician-educator and health services researcher and the Director of Clinical Effectiveness at Memorial Sloan Kettering Cancer Center (MSKCC), where she is also Chief of the General Internal Medicine Service. She earned a BA in Mathematics from the University of Pennsylvania and her MD from Columbia University’s College of Physicians & Surgeons and completed internship and residency in internal medicine at Beth Israel Hospital in Boston. Prior to her role at MSKCC, Dr. Korenstein was Editor-in-Chief of ACP Smart Medicine, an evidence-based clinical decision support tool, and the founding director of the Primary Care Residency Program at the Icahn School of Medicine at Mount Sinai. Her main academic efforts, in both education and research, have concerned high value physician decision making with research activities encompassing both educational and health services research. Specifically, she has focused her educational efforts around evidence-based medicine and high-value care and has performed research in the areas of overuse of medical services and the impact of conflicts of interest. She has worked with national organizations including the ABIM Foundation, the American College of Physicians, and the Lown Institute to advance the study of overuse and to foster healthcare value and has been deeply involved in national campaigns including the Choosing Wisely campaign.

    • Hospitalist at United Medical Center

    I completed medical school at Sidney Kimmel Medical College (formerly Jefferson Medical College) in Philadelphia, PA and my residency training in Internal Medicine at George Washington University Hospital in DC.  I then went on to compete a 1-year fellowship in Medical Education, also at GW and am currently practicing as a hospitalist in DC. Specific topics of interest include the development of hospitalists and residents as clinician-educators, mentorship in medical education, and the role of literature/the humanities in medicine.

    I am a hospitalist at Thomas Jefferson University in Philadelphia, PA. I am also a clinical lead at Jefferson's Digital Technologies group that is focused on bridging the gap between clinical medicine and innovation.C I have a strong interest in innovation and leadership in the field of medicine. In the pursuit of these interests, I have held multiple leadership positions such as President of Jefferson's Student Council and CEO of the Community of Health & Innovation Professionals (CHiP) to name a couple, where the sole mission was to revolutionize the medical field for both physicians and their patients. Other interests include being captain of Jefferson's flag football team, Wing Chun kung fu, cooking, and playing bass guitar in a local band. Very interested in networking with anyone who would like to help foster and develop ideas or projects for a better tomorrow, whether that be innovating inside the field of medicine or the individuals affected by it.

    • Pediatric Infectious Diseases
    • Professor of Pediatrics in Infectious Diseases at University of Tennessee School of Medicine

    Dr. DeVincenzo is currently VP of Translational Biology at Enanta Pharmacueticals.  He recently completed a 25 year role as a Practicing Pediatric Infectious Diseases Specialist at Le Bonheur Children’s Hospital in Memphis Tennessee and Professor of Pediatrics and Professor of Microbiology, Immunology, and Biochemistry at the University of Tennessee School of Medicine. His research has focused on understanding the pathogenesis of respiratory syncytial virus (RSV) directly in children and using this understanding to develop therapeutic and prevention strategies against this virus.  He is the author of over 250 original published abstracts and papers on this subject.  Dr. DeVincenzo’s research initially focused on the immunogenetics of RSV disease and the interplay between viral dynamics and RSV disease severity in infants.  Subsequently, his research focus shifted to apply this knowledge of RSV dynamics to the development of novel therapeutics for RSV.  His development of RNA interference-based therapeutics for RSV has shown recent success.  For his groundbreaking proof of concept work applying RNA interference concepts to develop human therapeutics, Dr. DeVincenzo’s study was listed as one of the most influential papers in medicine in 2010 (American Society for Microbiology).  From this work, Dr. DeVincenzo set about developing antivirals and vaccines using a variety of approaches for RSV; from conception to proof of concept clinical trials through several academic, foundation, and industry pathways.  He and colleagues have demonstrated the first evidence that treating an established RSV infection in humans can lower the viral load and result in reduced disease. He has subsequently extended similar proofs of human antiviral RSV-therapeutic efficacy for four other novel antiviral compounds with different mechanisms of action.  He is currently progressing several international RSV antiviral programs into pediatric and adult populations in his new role at Enanta Pharmaceuticals.

    Dr. DeVincenzo received his undergraduate degree in biology from Stanford University, and then attended Vanderbilt Medical School where he became interested in pediatric infectious diseases and earned his MD degree.  His internship and residency were completed at U.C.L.A Center for Health Sciences.  After finishing his pediatrics training, Dr. DeVincenzo studied tropical medicine at Walter Reed and practiced general medicine in Central Africa before starting formal training in Pediatric Infectious Diseases at Boston Children’s Hospital and Harvard Medical School.  During this time, he also completed a research fellowship at the Dana Farber Cancer Institute working with his mentor, George Siber, in developing passive antibody approaches for RSV treatment and prevention.  Dr. DeVincenzo has conducted numerous clinical and translational trials in children refining the pathogenesis of RSV and defining the role of prevention and therapeutic applications of monoclonal antibodies targeting RSV in infants and the immune suppressed.  He ran an active NIH-funded academic laboratory studying RSV and other respiratory viruses for over a decade, and has received numerous honors for his research including honorary induction into Alpha Omega Alpha National Medical Honor Society (2009), the Healthcare Heroes Award for innovation (2008), and the best advance in Therapy and Prevention of a Microbial Disease (ICAAC 2007). Dr. DeVincenzo was also the medical director of the University affiliated Le Bonheur Children’s Hospital Diagnostic Virology Laboratory and the Methodist/Le Bonheur Molecular Diagnostics Laboratory. He is a board certified pediatric infectious disease specialist, has lectured nationally and internationally, and has received awards for clinical teaching of medical students, residents, and fellows.
