Dr. Roll was a PhD student when the lab opened and has been a long term contributor to the many ongoing research projects at OSU. Dr. Roll is current serving as the PI for the survey research being conducted on the work-related musculoskeletal injuries. Dr. Roll will be working closely with Drs. Evans and Sommerich to develop a national database for sonographers and sonologists health and well-being. Dr. Roll received his OT-BS, MS, and PhD degrees at The Ohio State University. Dr. Roll has been funded multiple times by CDC-NIOSH and National Science Foundation (NSF).
Carolyn M. Sommerich, PhD, CPE, FHFES -Professor, tenure track, has been a long term collaborator and has been highly involved in several of our research projects. As a Certified Professional Ergonomist, her expertise is highly valued in our lab. Dr. Sommerich has been funded multiple times by CDC-NIOSH and has served as a grant reviewer for CDC-NIOSH. She is also a past-President of HFES. Drs. Sommerich and Roll are highly involved in our ongoing survey research to better understand the risk of work-related musculoskeletal injuries in ultrasound users. Ongoing scholarship and lectures are planned by our research group.

Ryan Walsh, PhD
Post-Doctoral Scholar
Ryan Walsh, PhD, OTR/L is a post-doctoral scholar that is working in Dr. Roll’s lab at the University of Southern California. Dr. Walsh has extensive training in statistical analysis and was recently awarded a F32 postdoctoral fellowship grant from the NIH National Institute on Minority Health and Health Disparities, to study social determinants of health and health disparities in emerging work contexts. The project will use quantitative and qualitative data to learn how the effects of emergent work intersect with workers’ ability to lead satisfying, meaningful and productive lives in their communities. Dr. Walsh is completing the complex data analysis for the WRMSD survey project and is also a statistician for the Journal of Diagnostic Medical Sonography.

Christopher Kanner, MD – OSU Radiology
I am also so thankful for the ongoing support of Christopher Kanner, MD -Assistant Professor, Musculoskeletal Radiology. Chris started his career as a research technician in our lab. Dr. Kanner graduated from the University of Cincinnati College of Medicine and completed his Radiology residency at The Ohio State University’s Radiology Department. He continued his skills and expertise by completing a Fellowship in musculoskeletal imaging. As a staff Radiologist, Dr. Kanner is still providing our lab with advice and mentoring opportunities for our pre-med students.

Matt Farrow, PhD
Post-Doctoral Scholar
We are also excited to be working with Matthew Farrow, PhD, as he is a post-doctoral scholar at OSU and being mentored by Dr. Yarar-Fisher. Dr. Farrow earned his MSci Sport & Exercise Science from the University of Bath, in the UK. Upon completing his PhD, he continued his research endeavors as part of the OSU Department of Departments of Physical Medicine and Rehabilitation and Neuroscience, as well as the Beford Center for Spinal Cord Injury. Drs. Farrow and Yarar-Fisher are dedicated to better understanding the effects of diet and exercise to reduce the risk for atherosclerosis in wheelchair bound patients. Our current work together is providing new data on vascular flow in the SMA and the peripheral vascular arterial system.
