Biography
Since May 2024, Jan ±áö±ô³Ù²µ±ð, Ph.D., has been appointed as an Assistant Professor of Research at the Resilience Research Centre, which is affiliated with the School of Social Work at É«ÃÃÃÃÖ±²¥. His Ph.D. thesis (2015-2018) focused on the resilience and healthy aging of former indentured child laborers in Switzerland and how stressful experiences can support individual-level resilience. During his first postdoctoral scholarship (2019-2021), he studied the underlying multisystemic mechanisms of resilience in youth impacted by volatile industries in Canada and South Africa. During his second postdoctoral scholarship (2022-2023), he studied the resilience of Native Hawaiian youths and adults in the context of their past and ongoing colonization.

Today, his critical, participatory, multidisciplinary, mixed-methodÌýresearch follows a multisystemic understanding of youth resilience to support the comprehensive well-being of youth when faced with adversity. Thus, in contrast to mainstream resilience research, Dr. ±áö±ô³Ù²µ±ð emphasizes and studies the role of the environment for holistic youth resilience. Following a space-based and population approach to resilience, he wants to create communities where multiple dimensions of well-being and development are protected and promoted in all youth. Also, Dr. ±áö±ô³Ù²µ±ð is at the forefront of studying resilience with a systemic perspective by researching how different resource systems, such as biological, psychological, social, institutional, and ecological systems, work together to foster youth resilience. Dr. ±áö±ô³Ù²µ±ð has advanced knowledge in statistical analysis methods to study what works for whom under which circumstances via mixture modelling and decision tree methodology, and to study reciprocal relationships and interdependencies via network analysis and cross-lagged panel modelling.

Dr. ±áö±ô³Ù²µ±ð always welcomes new collaborations that aim to build a world where children and youth can holistically thrive, no matter who they are and what they face.
