Dr Thies studied the effects of uneven surfaces on gait stability at the University of Michigan (USA), including both experimental and modelling approaches, and the resulting publications (7) have received over 139 citations (ISI) across the last 8 years.

She joined the University of Salford in 2005 to work on the European Union project “Healthy AIMS” where she supported the design of a movement pattern recognition algorithm to trigger functional electrical muscle stimulation to assist stroke patients with hand opening. She has since worked on the EPSRC I’DGO-TOO project that aims to improve urban design to enhance older people's quality of life (; there she evaluated walking stability of older adults when crossing the road and investigated the effect of tactile pavement on their balance.
