David J. Malan is a prominent figure in computer science education, serving as the Gordon McKay Professor of the Practice of Computer Science at Harvard University. He is best known for teaching CS50, Harvard's introductory computer science course, which has become one of the university's largest and most popular offerings. Malan's teaching extends beyond Harvard, as CS50 is also taught at Yale University and is available as a massive open online course (MOOC) on edX, attracting millions of learners worldwide. His expertise spans various areas of computer science, including cybersecurity, digital forensics, and computer science education. Malan's journey in computer science began as a student at Harvard, where he initially studied government before discovering his passion for programming through CS50. He went on to earn his bachelor's, master's, and doctoral degrees in computer science from Harvard. In addition to his work at Harvard's School of Engineering and Applied Sciences, Malan is a member of the Faculty of Education in the Graduate School of Education and teaches at Harvard Business School, Harvard Law School, Harvard Extension School, and Harvard Summer School. His innovative teaching methods, engaging lectures, and commitment to making computer science accessible to all have earned him recognition as a leading educator in the field.

Doug Lloyd is a Senior Preceptor in Computer Science at Harvard University's Division of Continuing Education. He earned his A.B. in Computer Science from Harvard in 2009 and has since become an integral part of the CS50 team. Lloyd currently serves as CS50's Head of Online Education Initiatives, coordinating all thirteen CS50 courses on edX and acting as the Head Teaching Fellow for the program's courses at Harvard's Division of Continuing Education. His involvement with CS50 dates back to 2007 when he began as a teaching fellow. Lloyd has also taught his own courses, including web programming and software engineering, at various Harvard schools. Known for his distinctive style of wearing shorts and polo shirts, he has become a familiar face to many CS50 students both on-campus and online. Beyond his academic work, Lloyd is a licensed attorney, a private pilot, and has appeared on the game show Jeopardy

Brian Yu is a Senior Preceptor in Computer Science at Harvard University's Division of Continuing Education, a position he assumed shortly after completing his undergraduate studies. Yu graduated from Harvard in 2019 with an A.B. in Computer Science and Linguistics, demonstrating his expertise in both fields. Despite his relatively recent graduation, Yu has quickly established himself as a valuable member of Harvard's computer science education team. He is particularly known for his involvement with CS50, Harvard's popular introductory computer science course. Yu's contributions to CS50 include developing course materials, delivering lectures, and creating educational content for both on-campus and online learners. His dual background in computer science and linguistics allows him to bring a unique perspective to his teaching, often incorporating elements of natural language processing and computational linguistics into his work. Yu's rapid ascent from student to educator at one of the world's most prestigious universities underscores his exceptional talent and dedication to computer science education
