An advanced degree in Oral Biology and Pathology can lead to various career paths in the biomedical sciences and industry as demonstrated by a few of the graduates from our program highlighted below:

Zegong headshot

Zhang Zegong, PhD

Dr. Zegong currently works at the School of Dental Medicine at Stony Brook University as a Research Scientist.  He received his PhD in 1996 under the mentorship of Dr. Israel Kleinberg. His research focuses on cutaneous microbiomes, reduction of body odorous microbiomes and Staph.aureus infections. The ecology , modeling and metabolism of skin microflora, and the role of skin bacteria in acne, wound healing, atopic dermatitis and like conditions are underway.  Obesity research is in the early stages of study using microflora manipulation methods.

Mark S. Wolff, DDS, PhD

Dr. Mark S. Wolff was named Dean at the University of Pennsylvania School of Dental Medicine July 1, 2018.  Prior to this prestigious appointment Dr. Wolff served as Professor and Chair of Cariology and Comprehensive Care, as well as Associate Dean for Predoctoral Clinical Education at New York University College of Dentistry.  He received his PhD in 1997 under the mentorship of Dr. Israel Kleinberg. He has served as the principal or co-principal investigator on multiple bench top and clinical research projects investigating dental caries, novel remineralizing agents, dental erosion, periodontal disease, dental materials and dentinal hypersensitivity. He has published over 75 scientific papers, text chapters and edited multiple textbooks. Dr. Wolff lectures world-wide and is a frequent consultant to industry. He has been the principal or co-principal investigator on more than $6 million in industrial and National Institute of Health (NIH) funded research.

Bruce J. MacKay, PhD

Dr. Bruce J. MacKay received his PhD in1982 under the mentorship of Dr. Jerry Pollock.  He served as Vice President, Scientific Affairs for Del Laboratories and is the Former Worldwide Director for Johnson and Johnson.  He is currently the Principal for MacKay and Associates. He has launched 80+ new products/product upgrades (excluding cosmetics initiatives) and is the Co-author on 17 papers and 33 abstracts. Dr. MacKay is the Co-inventor on 9 patents and holds a Regulatory Affairs Certification (RAC).

Maria Emanuel Ryan, DDS, PhD

Dr. Maria E. Ryan received her PhD in 1998 under the mentorship of Dr. Lorne Golub.  Dr. Ryan currently serves as Vice President and Chief Dental Officer at Colgate Palmolive Company in New Jersey.  Formerly she chaired the Department of Oral Biology and Pathology at the School of Dental Medicine at Stony Brook University.  Dr. Ryan currently serves on several scientific, dental and medical advisory boards. Dr. Ryan’s research has been funded by the National Institutes of Health (NIH), private foundations and industrial sources.  She holds several U.S. patents and was inducted into the National Academy of Inventors in 2016.  Dr. Ryan lectures frequently and has appeared on multiple media outlets including CNN, NBC, ABC and NPR to discuss newly emerging therapeutics and diagnostics, the connections between oral and systemic health and the need for early detection of periodontal disease and oral cancer.

Jonathan Garlick, DDS, PhD

Dr. Jonathan Garlick received his PhD in 1993 under the mentorship of Dr. Lorne Taichman. Dr. Garlick currently holds the position of Professor of Oral Pathology at the Sackler School of Biomedical Sciences at Tufts University. Dr. Garlick's work focuses on bioengineering human tissues to study stem cells, cancer, and to fabricate tissue platforms for drug discovery. His lab performs studies at the interface of tissue engineering and stem cell biology using 3D, skin-like tissues constructed from cells derived from pluripotent stem cells to study their behavior in a biologically-relevant tissue context in ways that will inform their future therapeutic application.
