Dr. Brian L. Davis
Title: Director of Research, Professor
Dept/Program: Biomedical Engineering
Office: Auburn Science & Engineering Center 209E
Brian Davis holds both a bachelor’s degree in Mechanical Engineering, and a master’s degree in Medicine (Biomedical Engineering) from the University of Cape Town (South Africa), and a Ph.D. from Penn State University. He had a staff-level appointment at the Cleveland Clinic from 1992 to 2010.
In terms of medical devices, Dr. Davis has led a number of initiatives focused on rehabilitation technology and instrumentation for assessing a patient’s risk for diabetic foot ulceration. He is currently the Principal Investigator on a State-funded project aimed at commercializing sensors for diagnosing connective tissue disorders. He is also leading an educational program named “BEST Medicine” that encourages middle and high school students to develop interests in engineering, science and technology, particularly as these relate to designing novel medical devices. Dr. Davis is a member of a number of professional societies, including the International Society of Biomechanics – a society for which he served as President from 2005 to 2007.
During his time at the Cleveland Clinic he was the first investigator to receive a peer-reviewed grant from NASA headquarters on the topic of foot biomechanics in response to impact loading (1996-1998), the first investigator to obtain funding from the Juvenile Diabetes Research Foundation, and the first to obtain a four year grant from the Howard Hughes Medical Institute. He subsequently received funding to develop and test an exercise countermeasure device for astronaut use and was part of a team that developed biomechanical sensor instrumentation that is currently on the International Space Station.
Over the past 18 years, Dr. Davis has served as Principal Investigator and secured external peer-reviewed funding in excess of $25,000,000.
Diabetic Foot Ulceration: The importance of mechanical factors such as pressure and frictional forces has been established as key in the etiology of diabetic foot ulcers. The rationale behind our research is that by quantifying localized skin loads and obtaining noninvasive measurements of tissue properties, factors leading to diabetic skin ulceration will be more fully understood. Diabetic foot research in our laboratory includes development of (i) a device for simultaneous measurement of pressure and shear forces under the feet of patients; (ii) software algorithms for visualizing and interpreting shear and pressure data.
Prosthetic sockets and liners: Improve transfemoral prosthetic comfort by optimizing the thermal properties of the liner and socket polymer components. Our group has funding from the U.S. Department of Veterans Affairs for the development of new materials.
An additional interest and active area of research relates to biomedical sensors. Our group has funding from the Wright Center for Sensors and Systems Engineering to develop five different sensors --- all related to assessing connective tissue disorders.
