Brief Introduction

Topic 1:    Combating Obesity: Our Current Understanding and Challenges
Speaker:  Prof. Chan Chi Bun
                  Associate Professor, School of Biological Sciences, The University of Hong Kong

Obesity is a widespread metabolic disorder with increasing prevalence across the globe. In Hong Kong, the incidence of obese adults in the population has surged from 21% in 2003 to 33% in 2020. Given obesity might lead to numerous diseases, including stroke, heart attacks, diabetes, and even cancer, the mounting number of obesity cases could significantly strain the healthcare and economic system. This lecture discusses the biological and social causes of obesity, its detrimental impact on health, and the latest research on preventive and therapeutic methods to combat obesity.

Topic 2:    Novel Ultra-Precision Machining Technology Enters Innovation, Technology and Life
Speaker:  Ir Prof. Cheung Chi Fai, Benny
                  Chair Professor of Ultra-precision Machining and Metrology, Department of Industrial and Systems Engineering,
                  Director of State Key Laboratory of Ultra-precision Machining Technology,
                  The Hong Kong Polytechnic University

Ultra-precision machining is a kind of advanced manufacturing technology which is critical for many industries including biomedical, semiconductor, optometry, etc. The lecture discusses the development and application of ultra-precision nano multi-ring machining technology to the development of a novel and high-efficacy nano multi-ring defocus incorporated spectacle lens for myopia control which benefits short-sighted population. This research application demonstrates how technological innovations are transformed through interdisciplinary research and industrial collaboration for the betterment and lasting impact of human life.
