If you ask why my students are dedicated to studying computer science, my response would hark back to President Kennedy's remarks at Rice University in 1962, where he proclaimed—permit me to paraphrase—-- "We choose to pursue the CS degree, not because it is easy, but because it is hard. Because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we’re willing to accept. One we are unwilling to postpone. “

Teaching Focus

Professor Dai has taught ABET-accredited undergraduate and graduate courses in face-to-face, hybrid, and online modalities since 2019 in the USA. In particular, teaching a wide range of courses, from undergraduate-level Algorithms to Deep Learning and Advanced Artificial Intelligence, has made him aware of the needs and interests of a culturally and ethnically diverse student body. His objective as an instructor is to motivate students to develop their own learning interests and critical thinking—to establish a learner-centered environment in the classroom.
