Interests & Expertise

Inga Wang (former Ying-Chih Wang), OTR/L, PhD, is an Associate Professor with tenure at the Department of Occupational Science & Technology. Dr. Wang received a MS in Biotechnology from the Johns Hopkins University and earned her PhD in Rehabilitation Science from the University of Florida. Additional training was completed as a postdoctoral research fellow in the Sensory Motor Performance Program (SMPP) at the Rehabilitation Institute of Chicago (RIC).

In the past few years, Dr. Wang has assisted Dr. Craig Velozo in several outcome research projects, related to computerized adaptive testing (CAT) and score equating, funded by the National Institute on Disability and Rehabilitation Research (NIDRR) and VA Rehabilitation Research and Development (RR&D) and has assisted Dr. Zev Rymer, Vice President for Research at the RIC, to execute projects funded by National Institutes of Health (NIH). The main purpose of the NIH funded Toolbox project is to provide investigators with a brief, but comprehensive, measurement tool for assessment of cognitive, emotional, sensory and motor function of participants in large cohort studies such as epidemiological studies, clinical studies, or clinical trials, as part of the NIH Blueprint for Neuroscience. In 2009, Dr. Wang was funded by a 5-yr NIDRR training center grant as a PI on Sub-Project on enhancing the functional and employment outcomes in individuals who experience a Stroke.

Her current research interests are to (1) Stroke rehabilitation, (2) develop quantitative functional outcome measures and to perform comparative effectiveness research with new rehabilitation technologies, (3) examine the psychometric properties of patient-reported outcomes, and (4) use big data analytics in healthcare to develop norms, trends, and predict risk factors. In particular her laboratory is currently working on developing a quantitative spasticity in routine clinical care, studying the effectiveness of the robotic assisted therapy using the ArmeoSpring in improving motor recovery of the paretic arm, describing the population-based norms of physical functioning across the life span, and understanding the longitudinal trends and overall risk factors in major cardiovascular conditions.
