Ken M. Hargreaves, DDS, PhD

Photo Professor and Chair of Endodontics
Professor of Pharmacology and Physiology
University of Texas Health Science Center at San Antonio
Email | UT Pharmacology faculty profile

Education: DDS, Georgtown University, Washington, DC, 1983
PhD, Uniformed Services University of the Health Sciences, Bethesda, MD, 1986

Research project: My primary research interests are in the pharmacology of pain and inflammation. A major focus is on pharmacological regulation of unmyelinated "C" fiber nociceptors, as well as their plasticity in response to inflammation or nerve injury. Investigations are in progress evaluating the effects of cannabinoids, opioids, adrenergics, NPY, sex steroids and other drugs on regulating the activity of these fibers. In addition, we are interested in identifying major classes of inflammatory mediators and associated receptor/signal transduction systems which mediate activation, sensitization and phenotypic plasticity of these primary afferent fibers in response to tissue inflammation. Responses are measured using isolated superfused tissue, primary trigeminal cultures, microdialysis probes implanted in situ, RIA, EIA, real time PCR, Affymetrex analyses, IHC, ISH, confocal microscopy, behavior, etc.

Research laboratory: Video intro to Dr. Hargreaves' lab

Biosketch: Dr. Hargreaves received his BA in neurobiology from the Univeristy of California at Berkeley in 1977, his DDS from Georgetown University in Washington DC in 1983, and his PhD in Physiology from the Uniformed Services University of the Health Sciences in Bethesda, Maryland in 1986. From 1986 to 1990, he was a Staff Fellow and Senior Staff Fellow at the Neurobiology and Anesthesiology Branch of the National Institute of Dental Research (now NIDCR) at the NIH. He completed his residency in Endodontics at the University of Minnesota in 1993 and is a Diplomate of the American Board of Endodontics. Dr. Hargreaves is currently Professor and Chair of the Departent of Endodontics, and Professor in the Department of Pharmacology, Department of Physiology and Department of Surgery at The University of Texas Health Science Center at San Antonio. He also maintains a private practice limited to endodontics.


Martin G. Schwacha, PhD

Photo Professor of Surgical Research
University of Texas School of Medicine San Antonio, Department of Surgery
Division of Trauma and Emergency Surgery
Email | UT faculty profile

Education: PhD, Albany Medical College, Albany NY in 1992

Research project: The Trauma Immunopathology Research Laboratory is a multidisciplinary laboratory devoted to the study of traumatic and burn injury. Studies within the laboratory encompass both laboratory and clinical research and are directed towards improving our understanding of the body's reaction to injury and infection at an immunological, pathological and physiological level. It is our hope that the systematic analysis of the body's response to traumatic injury can lead to the development of improved and innovative therapies for the treatment of burn and trauma patients.

Research laboratory: Trauma Immunopathology Research Laboratory

Biosketch: Martin G. Schwacha is a Professor of Surgery at UTHSCSA in the Division of Trauma and Emergency Surgery. He also holds the position of Research Scientist at the US Army Institute of Surgical Research. He has serves/served on the editorial boards of Shock and International Journal of Clinical and Experimental Medicine as well as an ad hoc reviewer for numerous other scientific journal. Martin has also served as a review committee member for the NIH, Shriner's Hospital and DoD Congressionally Directed Medical Research Programs and is an active member of a number of scientific societies focused on trauma, infection and/or immunology. He has obtained research funding from both the NIH and DoD. Martin received his BS from the University of Rhode Island in 1981. After working for the Veterans Administration in Providence RI as a research assistant he entered graduate school and obtained a PhD from Albany Medical College, Albany NY in 1992. Postdoctoral studies in immunology were completed at the Gamble Institute, Cincinnati, OH and Temple University, Philadelphia, PA. In 1997 he joined the Surgery faculty at Brown University, Providence RI and subsequently joined the faculty at University of Alabama at Birmingham in 2000. In 2008 he joined the faculty at UTHSCSA.


Paula K. Shireman, MD

Photo Professor of Vascular Surgery and
Vice Dean for Research, Dielmann Chair in Surgery, UT School of Medicine San Antonio

University of Texas School of Medicine San Antonio, Department of Surgery
Division of Vascular/Endovascular Surgery
Email | UT faculty profile

Education: MD, Indiana University School of Medicine, Indianapolis, IN, 1990

Research project: Our lab studies the inflammatory-mediated mechanisms of angiogenesis and skeletal muscle regeneration. We are particularly interested in how hematopoietic stem cells, myogenic stem cells and inflammatory cells interact to form muscle after injury. A better understanding of muscle regeneration will be useful in tissue regeneration strategies for limb salvage.

Research laboratory: Dr. Shireman's Vascular Research Laboratory

Biosketch: Dr. Shireman obtained her medical degree from Indiana University School of Medicine in Indianapolis, IN in 1990 and completed her Vascular Surgery training at Loyola University Medical Center in Maywood, IL in 1998. She is currently certified with the American Board of Surgery in both General Surgery and Vascular Surgery. Dr. Shireman joined the Vascular Surgery Division at the Health Science Center in 1999. After arriving at the Health Science Center, Dr. Shireman completed her masters program in Clinical Investigation and received numerous grants for research from the NIH, the Department of Veteran Affairs, Howard Hughes Medical Institute, the American Heart Association, and the University of Texas Health Science Center at San Antonio. In 2004 Dr. Shireman was appointed to the faculty for the Barshop Institute for Longevity and Aging Studies.


Ross E. Willis, PhD

Photo Associate Professor
Director of Surgical Education
Director, Johnson Center for Surgical Innovation
Department of Surgery
Email: willisr@uthscsa.edu | UT faculty profile

Education: PhD, Cognitive Psychology, Texas Tech University, Lubbock, TX in 1999

Research projects: The Surgical Education Research Laboratory is devoted to enhancing surgical education by empirically examining and applying principles of cognitive psychology and learning theory to the surgical education environment. Researchers in the laboratory develop and evaluate curricula, validate evaluation and assessment methods, and discover optimum methods of teaching and learning knowledge and skills.

Research laboratory: Surgical Education Research Laboratory

Biosketch: Dr. Willis holds a master's degree in human factors psychology and a doctoral degree in cognitive psychology from Texas Tech University. After graduate school, he worked with the Air Force Office of Scientific Research at Lackland Air Force Base conducting basic and applied research in the areas computer-based instruction and cognitive task analysis. He left research to co-found an e-learning company, while keeping touch with the academic world by holding a position as an adjunct professor at University of Houston. Dr. Willis chose to pursue his love of academia full-time and joined the UTHSCSA faculty in 2007.
