About

Dr Chalchisa Abdeta (PhD)

I’m Dr. Chalchisa Abdeta (PhD) — though many know me simply as Dr Chali. I’m a researcher, mentor, and health promotion advocate passionate about turning scientific evidence into practical tools that help families, young people, and communities thrive. My journey began in Ethiopia, where I trained as a physiotherapist before completing a Master of Public Health. More recently, I earned my PhD from the University of Wollongong, Australia, focusing on adherence to the World Health Organisation’s 24‑hour movement behaviours — physical activity, screen time, and sleep — and their impact on young children’s health and development.


Over the years, I’ve led international collaborations, published extensively, and made significant contributions to global research initiatives such as the SUNRISE International Study led by Distinguished Prof. Anthony Okely in Australia and the Active Healthy Kids Global Alliance led by Prof. Mark Tremblay in Canada. I’ve also had the privilege of working alongside influential researcher Prof. John Reilly from Scotland, who is part of the leadership team for both studies. I was awarded an international grant of $5,000 USD for my PhD research translation through the 2022 Patrice L. Engle Dissertation Grant in Early Child Development, USA. Additionally, I received the 2022 Outstanding HDR Proposal Award from the University of Wollongong for the strongest HDR Research Proposal Report, valued at A$200, as well as a Higher Research Degree full scholarship from the University of Wollongong, Australia, to pursue my PhD at Early Start Research. To date, I have achieved an h-index of 10, with more than 1,800 citations. 


Beyond research, I founded DrChali—practical lifestyle insights that empower families, young people, and communities. Outside of work, I enjoy walking with my wife and our two young boys.
