Prof. Sharon Toker

Sharon Toker is currently an Associate Professor and the head of the Healthcare Management program at Tel Aviv University’s Coller School of Management.

Prof. Toker graduated from Tel Aviv University, completing her B.A. in Psychology and Sociology (1997) and her PhD in Organizational Behavior with distinction (Accelerated Doctoral Program, 2007). In 2008 she completed her postdoctoral fellowship at Stanford University and soon after joined the Department of Organizational Behavior in Tel Aviv University’s Coller School of Management.

Prof. Toker is the associate editor of the Academy of Management Perspectives Journal and the Occupational Health Science Journal. She has published more than 30 papers and book chapters and was awarded the Early Career Achievement Award by the American Psychological Association (APA) and the National Institute of Occupational Safety & Health (NIOSH) in 2013.

Prof. Toker teaches Organizational Behavior and Stress Management courses. She was granted numerous teaching awards including the Tel-Aviv University Rector Award (2013), Tel-Aviv University best 100 lecturers awards, and the Coller School of Management teaching awards in 2013, 2015, 2016, 2017 and 2018.

In addition to her academic activity, Prof. Toker is an active advocate for employees' wellbeing. She is working with the Israeli Ministry of Health and with the Ministry of Law to reduce employees' burnout levels. She is also an illustrator, translating her research findings into visual images. Her illustrations appear in both academic and non-academic outlets.

Prof. Toker’s research strives to discover the extent to which occupational and environmental factors, stress perceptions, and organizational resources affect the physical and mental wellbeing of employees. By combining various areas of knowledge such as occupational psychology, cognition, and medicine, in addition to conducting experimental as well as observational longitudinal studies among thousands of employees, she points to the risk involved in exposure to occupational and environmental stressors (including the fear of terrorism). She also strives to identify effective ways of coping with such risks. Her studies combine new models and constructs that are at the forefront of current psycho-occupational research (e.g., stress perceptions and mind wandering). As an expert in the field of work stress and health, Prof. Toker’s research serves as the basis for policy change on both national and international scales. 

 

Focal topics of Prof. Toker’s research include:

>> Stress, burnout, and employee health

>> Stress theory, perception, and mindset

>> Mind wandering at work

>> Health promotion in organizations

>>  Gender inequality at work

>>  Organizational cynicism
