Professor Lai is known for his passion in teaching organic chemistry and he is remembered by most of his students for setting challenging examination questions. His decision to take up the position as the principal of the NUS High School of Mathematics and Science was to fulfill a childhood dream. One of his main aim as the principal is to develop a passion in learning in the students. In an interview with the Ministry of Education, he said that "the passion for learning in general would build up a good foundation for learning, qualities such as determination, going the extra mile, doing things outside the curriculum. We would like to look at academic excellence as the outcome of the passion rather than the goal".
