Mads Torgersen is the Language PM for C# at Microsoft. He runs the C# language design meetings, takes the notes, maintains the language specification and that type of language lawyer activity. He also occasionally gets to go out and meet real customers, as well as some of the self-established customer spokespeople that populate events like CodeMash. Before joining Microsoft 3 years ago, Mads was almost a real academic, working as an Associate Professor at a Danish university and doing programming language research. During that time he ran a collaboration with Sun Microsystems to design and implement generic wildcards in Java.
