Hey, I'm Leon! I'm a third-year PhD candidate at the Department of Mathematics of VU Amsterdam. My work focuses on machine scheduling and vehicle routing problems motivated by industrial applications. I enjoy tackling large-scale, stochastic and dynamic problems, and building simple methods and software to solve them.
