Research Team


Jacob Sosnoff, Ph.D.

Professor, Department of Physical Therapy, Rehabilitation Science and Athletic Training
Associate Dean for Research, KU School of Health Professions

Postdoctoral Fellow

Tobia Zanotto, Ph.D. 

Dr. Zanotto joined the Mobility and Falls Lab as a postdoctoral fellow, funded by a mentor-based fellowship, in the spring of 2021. He holds a Ph.D. in Physiotherapy from Queen Margaret University, Edinburgh (UK). His doctoral research examined the relative importance of physical frailty and cardiovascular function as exercise-modifiable predictors of falls in people receiving hemodialysis for end-stage renal disease. Currently, Dr. Zanotto is exploring the impact of mobility impairments on quality of life and clinical adverse outcomes in people living with multiple sclerosis, as part of a mentor-based postdoctoral fellowship funded by the NMSS. Dr. Zanotto is also a judo black belt, and he is investigating the potential benefits of teaching safe-falling strategies adapted from the martial arts to prevent fall-related injuries, such as traumatic brain injury, in older adults.

Graduate Students

Lingjun Chen

Lingjun started her Ph.D. in the Mobility and Falls Lab in the summer of 2021. She received her BSc in rehabilitation therapy from Nanjing University of Chinese Medicine, Nanjing (China). She earned her MSc degrees in Physiotherapy from Cardiff University (UK) and in Kinesiology from University of Illinois at Urbana-Champaign, studying under Dr. Sosnoff. She is interested in balance and postural control in movements. Lingjun believes the multi-disciplinary research would bring opportunities in making differences in clinical practice. Currently, she is understanding the impact of natural aging on head control, as a part of the development of head impact prevention strategy during falls in the older populations.

James Fang

James joined the Mobility and Falls Lab as a Ph.D. student in the fall of 2021. He has his bachelor’s degree in mechanical engineering from Tsing Hua University, Hsinchu, Taiwan and has his master’s degree in dance education from Taipei National University of the Art, Taipei, Taiwan. His research interest is in quantifying motor function in health and disease, and he is currently working on gait analysis, using wearable devices to help people with multiple sclerosis.
