Postdoctoral fellows and honourary research associates

Esther Maas

Honourary Research Associate


Dr. Esther Maas worked on a program of research on gender and the evaluation of workers’ compensation policies and programs, with a particular focus on identifying effective and cost-effective approaches in facilitating early and sustained return-to-work after work injury. Esther earned a Master’s degree (hons) in Health Sciences from the University of Maastricht, and a Master’s degree in Epidemiology from the VU University in Amsterdam, both in the Netherlands. She completed her doctoral research at the VU University in the field of Health Sciences, in which she mainly focused on the cost-effectiveness of radiofrequency denervation for chronic low back pain. Her primary research interests include health technology assessment, economic evaluations, gender and health, and epidemiology, mostly related to musculoskeletal health.

Sonja Senthanar

Postdoctoral Research Fellow


Dr. Sonja Senthanar is working on a program of research that examines the return to work outcomes/trajectories, following a work injury or illness, of immigrant workers when compared to Canadian-born workers within British Columbia. Sonja completed her doctoral studies in the School of Public Health & Health Systems at the University of Waterloo in 2019. Her dissertation used a qualitative feminist approach to explore the employment integration experiences of refugee women. Her primary research interests include employment outcomes, gender, and work disability relating primarily to immigrant and refugee populations as well as how these relationships change within the context of new forms of work such as precarious employment.
