Dr. David Conlon is a Professor of Mathematics at Caltech, Pasadena, California. Dr. Conlon's research interests include Ramsey theory, extremal graph theory, additive combinatorics, pseudorandomness, and random graphs. In 2019, in recognition of his contributions to combinatorics, Dr. Conlon was awarded the Whitehead Prize. In a conversation with students from Simon Fraser University, Manan Sood, Wassim Khelifi, and Connor Marriam, Dr. Conlon talks about his early experiences with mathematics, tells a story of how a group of math students broke a secret door code, and describes his contribution to our better understanding of Ramsey numbers.
