Right before the World Table Tennis Championship in Düsseldorf, Germany, the 15th ITTF Sport Science Congress was held on the 27th and 28th of May, 2017. It brought together experts from all around the world with the idea of furthering collaboration between players, coaches and scientists to develop table tennis.

During the Congress, Rizal Wan gave two lectures. Rizal Wan specializes in Human Motor Control and learning, with the focus on skill acquisition. He has obtained the Gold Medal Award from Rotary International in 2005. His passion for sports began as a P.E. teacher, a position he held for 12 years. He is currently a Senior Lecturer at Republic Polytechnic, School of Sports, Health and Leisure where he teaches Heath & Wellness, Human Motor Control & Learning as well as Sports Coaching.
