Oral Biology PhD Program Faculty

In alignment with the institutional goals, scientific research is the most prominent activity of the faculty in the Division of Biosciences. Within the past few years, the volume and scope of research in the section has increased greatly. All faculty have substantial external funding, and a major NIH-funded training grant for dental, graduate, and post-doctoral students and junior faculty. The myriad of ongoing multidisciplinary research programs focus on: Molecular and Cellular Biology, inflammation and Immunity, Developmental Biology, Chemical Senses, Musculoskeletal Biology, Microbiology, and Biomaterials and Tissue Engineering. The broad range of projects provided ample opportunities for scientific collaborations among faculty as well as offer opportunities for scientific collaborations among faculty as well as offer opportunities for graduate and post-doctoral students to obtain versatile training in modern approaches to biology.

Michael Bailey, PhD

Associate Professor, Department of Pediatrics and Division of Biosciences
College of Medicine

Studies in Dr. Bailey's laboratory focus on determining the impact that the intestinal microbiota have on the local mucosal immune system, and on immune reactivity at systemic sites, particularly during periods of psychological stress. In past studies, they have shown that exposure to different types of psychological stressors change the community structure of microbiota in the intestines. Their goal now is to demonstrate that these changes have significant effects on the health of the host.

Prosper Boyaka, PhD

Professor, Department of Biosciences
College of Veterinary Medicine

Currently, my research interests focus on the regulation of immunity and inflammation in mucosal surfaces.  We also investigate means to utilize mucosal surfaces for provision of immunity against infectious diseases and strategies to control mucosal pathologies such as allergic reactions. For this purpose, we study adjuvants that could be used in mucosal vaccines to induce both mucosal and systemic immunity. Regulation of mucosal immunity by cytokines/chemokines and other innate factors represent the other major area of our research.

Skeletal and renal biology. Most recently, major projects are focused on the role of cytoskeletal proteins in regulating the function of cells responsible for the formation and maintenance of bone, the osteoblasts and osteoclasts. The use of mouse genetic models, coupled with a variety of cell biology techniques, allows us to determine the function of cytoskeletal proteins in skeletal growth and health.

Miaomiao Li, PhD

Miaomiao Li, PhD

Assistant Professor, Division of Biosciences 
College of Dentistry

Dr. Li's research mainly focuses on understanding the role of heparan sulfate in bone health and inflammation, with the goal to develop novel therapy towards osteoporosis, rheumatoid arthritis and periodontitis. Heparan sulfate is an essential polysaccharide universally expressed at the cell surface and in the extracellular matrix. By interacting with hundreds of proteins, heparan sulfate plays significant roles in human health and disease, which makes it represent a class of biomolecule of great pharmaceutical interests. Dr. Li has extensive experience studying how heparan sulfate works with specific proteins like osteoprotegerin, RAGE, and sclerostin, which are important for bone health and inflammation. The long-term goal of the Li lab is to use this knowledge to develop new treatments that can target heparan sulfate–protein interactions and help treat bone and inflammatory diseases.

Hillery C. Schiff, PhD

Hillery C. Schiff, PhD

Assistant Professor, Division of Biosciences
College of Dentistry

The Schiff research program focuses on postnatal development of the neural circuits that underlie taste-based behaviors such as sensation, perception, reward, and feeding. They examine maturation of inhibitory neurons and synaptic transmission, plasticity, and microcircuitry in the cortical sensory region for taste, the gustatory cortex. They are also interested in the mechanisms by which taste and nutrient-sensing modulate one another in the presence or absence of sensory and food experience. They are particularly interested in how these processes shape taste preferences, especially for sugar and other sweet tastes. In the lab, They use patch clamp electrophysiology, animal behavior, neural tracing, and fiber photometry imaging to probe these questions.
