To honor the remarkable legacy of Professor Sheng H. Lin, a world-renowned theoretical chemist and a foundational figure in Taiwan’s theoretical chemistry community, the Prof. Sheng H. Lin Lecture has been established. This lecture series not only recognizes Professor Lin’s groundbreaking contributions across diverse fields—from transition state theory and radiationless transitions to femtochemistry—but also aims to inspire future scholars through the example he set in advancing the frontiers of theoretical chemistry.
