Organization: University of Louisville School of Dentistry

Biography Text: Dr. Scott is the Associate Dean for Research and Enterprise at the University of Louisville School of Dentistry. He completed his B.Sc. degree in Microbiology at Heriot-Watt University, Edinburgh Scotland in 1987 and, as a N.A.T.O. Scholar, obtained his Ph.D. in Microbiology and Immunology from McGill University, Montréal, Québec in 1997. Subsequently, David was a Welcome Trust Research Fellow in the Department of Periodontology at King’s College London, under the supervision of Dr. Richard Palmer. He moved to the University of Louisville after 4 years as an Associate Professor in the oldest Oral Biology department in the world at the University of Manitoba. He is a member of the editorial board of Tobacco Induced Diseases, the Journal of Clinical Periodontology and Molecular Oral Microbiology. David studies the interactions of tobacco- and cannabis-derived toxins on the interactions between oral bacteria and the immune system in the context of gingivitis and periodontitis. This is Dr. Scott’s second visit to AAP. Recent Publications include: 1. Stocke K, Lamont G, Tan J, Scott DA*.
