Her work has involved partnerships with colleagues from diverse geographical and disciplinary origins, spanning the northern and southern hemispheres and crossing sociological, criminological, and economic boundaries. Beccy is passionate about developing international and transdisciplinary occupational science partnerships and aims to leverage her experience in this area to help create opportunities for cohesion and innovative partnerships while preserving the diversity that is vital to occupational science.

Rodolfo Morrison 
ISOS Membership Lead

Rodolfo Morrison is the current Director of the Department of Occupational Therapy and Occupational Science at the University of Chile and president of Chilean Society of Occupational Science. He has a degree in Occupational Sciences and an Occupational Therapist from the Austral University of Chile; and Master and Doctor in Logic and Philosophy of Science from the University of Salamanca. In addition, he completed a postgraduate degree in Science, Technology and Society at the Center for Human and Social Sciences of the Higher Council for Scientific Research (CCHS-CSIC) of Spain. His areas of work have focused on the analysis of the history and epistemological currents present in Occupational Therapy and Science, in particular, in the incidence of classical pragmatism in the profession. Other areas of interest for him are feminist studies of science, studies on sexual diversity, occupational science and the uses of body techniques and meditation as therapeutic intervention tools.


Liesl Peters 
ISOS Board Chair

Liesl Peters is an occupational therapist and academic with more than 15 years of experience within community development practice in a South African context. Opportunities to contribute to the health and development of communities across the globe through knowledge and practice related to human occupation has become increasingly urgent. In the interests of this important agenda Liesl has been committed to both the research and enactment of a socially-transformative occupational science that can readily engage with the real needs of communities. Her work and teaching within community development practice has focused on ‘doing occupational science’ where occupational science knowledge is co-critiqued, used and co-generated in order to serve local practice needs. Since 2005, she has been co-developing a framework for OT practice–Occupation-based Community Development (ObCD) (Galvaan & Peters, 2017; 2018)–that seeks to engage a decolonial justice-oriented praxis towards a transformed society. The ObCD has also been used by speech-language therapists working in community contexts in Cape Town, illustrating its developing potential to contribute in transdisciplinary ways – an important imperative for occupational science. For Liesl, occupational science could be a potentially powerful discipline, but occupational scientists have not yet positioned themselves well-enough to contribute in ways that might better serve humanity in different global and local spaces. With this, Liesl wishes to contribute to the strategic growth and positioning of occupational science internationally, in order for the discipline to build its potential. To her, innovative leadership in communities such as ISOS can play an important role in this respect. Liesl views that the insights that she has co-generated with communities and colleagues in teaching and practicing for both the Global North and South could offer valuable insights to such a process.
