The 23rd Annual Vincent duVigneaud Memorial Research Symposium, hosted by the Weill Cornell Graduate School of Medical Sciences (WGSMS), was held on May 6. Throughout the day, the Symposium featured award-winning research presentations and poster sessions by Ph.D. students of Weill Graduate School of Medical Sciences. Dr. Douglas Kerr, director of the Johns Hopkins Transverse Myelopathy Center, gave the keynote address: "Neurodegeneration and Regeneration in the Spinal Cord." Dr. Kerr, a neurologist, studies motor neuron diseases and the role of viruses in inducing these diseases. In his lecture, Dr. Kerr spoke of his laboratory studies and their prevention and reversal of neurodegeneration by therapeutic drugs.

Following opening remarks by Dr. David Hajjar, dean of the Graduate School, students presented 85 posters and slide talks during the day. Poster sessions were judged by more than 40 WGSMS faculty on significance of research, innovation, quality of data and overall presentation. The slide presentations, held in Weill Auditorium, gave senior graduate students an opportunity to speak on the culmination of their graduate research work to a panel of senior faculty judges: Dr. M. Flint Beal, Dr. Harel Weinstein, Dr. Lonny Levin and Dr. Joel Pardee.
At the end of the day, the winners of the Vincent duVigneaud Prizes ($1,000), Awards of Excellence ($750), and First-Year Student Awards ($500) were announced by Dr. Joel Pardee, associate dean of the Graduate School, during a reception at the Griffis Faculty Club.
