Sheetal Shah

Sheetal Shah, PhD


Sheetal Shah, PhD, is the academic director at Webster Leiden Campus, Webster University USA. As an educator and change maker at heart, she is a psychologist with a global orientation. She has had the privilege of applying many psychological theories to different contexts in the real world - for example, in education, public health, leadership, global citizenship and grassroots-level work.

Shah specializes in the field of counseling for chronic illnesses and trauma; her research interests are focused in the field of modern-day slavery and human trafficking. In 2012, she founded the Bijlmer Project, a research project investigating the needs of victims of human trafficking, and now volunteers with the intervention phase of the project, Bridge2Hope that addresses the psychosocial and vocational needs of sexually trafficked women and men in the European Union. This project has also been a successful experiential learning component for many courses that are taught in both the psychology and global citizenship programs at Webster’s Leiden campus.

Part of Shah’s philosophy of teaching has been to connect students to real-world problems, or what she calls the "classroom outdoors" or "classroom in the community" format. This approach focuses on using experiential learning components in the field to build on the theoretical underpinnings that students learn in the classroom. Having studied both in India and the UK, and having worked with an American educational system within a Dutch/European setting, her familiarity with diverse curricula has helped her understand and effectively respond to the evolving needs and dynamics of the international student profile that universities cater to as part of their global network.
