Education and Post-Graduate Work
Dr. Thomas (Tom) Diekwisch received a PhD in Anatomy from the Department of Anatomy and Cell Biology (1988, "summa cum laude"), a PhD in the Philosophy of Science from the Institute for Philosophy (2005, “magna cum laude”), and a DMD from the School of Dentistry at Philipps-University of Marburg, Germany (1986).
From 1994 until 2001, Diekwisch served as an Assistant Professor at Baylor College of Dentistry in the Department of Biomedical Sciences. During this time, he taught General and Oral Histology, developed a developmental biology research program, and directed the award-winning community science education outreach program Habitat for Science.
In 2001, Diekwisch was recruited to the University of Illinois at Chicago College of Dentistry to become the first Director of the Brodie Laboratory for Craniofacial Genetics and the Allan G. Brodie Endowed Chair. Two years later, he was appointed professor and head of the Department of Oral Biology at the UIC College of Dentistry.
Dr. Diekwisch returned to the College of Dentistry in 2014 as Professor and Head, Department of Periodontics and Director of the Center for Craniofacial Research and Diagnosis. Since then, Diekwisch has improved undergraduate and graduate periodontal program performance as well as research productivity in the Department. In 2017, he was appointed the Bernhard Gottlieb Endowed Chair in Craniofacial Research.
From 1987-1990, Tom Diekwisch trained with one of Europe’s pre-eminent periodontists at that time, Dr. Lavin Flores-de-Jacoby, in Marburg/FRG. Ever since his first exposure to periodontal research and clinic in 1987, his work has been dedicated toward understanding the development of periodontal tissues and discovering novel therapeutic aids to improve the oral health of patients suffering from periodontal disease. He hopes that with the current line of work, the practicing dentist and periodontist will be provided with future aids that will help with the biological regeneration of periodontal tissues.
Contributions to the area of periodontal research include a high-impact paper related to the mesenchymal origin of cementum (Diekwisch 2001), the first study demonstrating extensive movements of neural crest derived tissues during the development of the periodontium (Diekwisch 2002), the discovery that the dental follicle contains diverse progenitor populations which may independently give rise to various periodontal tissues (Luan et al. 2006a), a comprehensive analysis of the role of Hertwig’s Epithelial Root Sheath in tooth root development (Luan et al. 2006b), a characterization of the extracellular matrix environment influencing periodontal progenitor growth and differentiation (Dangaria et al. 2009) and studies related to the systems biology and epigenetics of periodontal progenitor populations (Dangaria et al. 2011a, Gopinathan et al. 2013). Our combined periodontal progenitor – surface topography approach to facilitate tooth replantation (Dangaria et al. 2011b,c) has found much acclaim in the popular press. In recent years, Diekwisch’s research has focused on the application of microRNAs and small molecules for the regeneration of periodontal tissues.
