Brief biosketch

Skip Garibaldi is a mathematician known for his work on algebraic groups, especially exceptional groups such as E8; the book Cohomological invariants in Galois cohomology with Alexander Merkurjev and Jean-Pierre Serre; and his work on the lottery, which led to changes in state policy and arrests.  Millions of people have seen him talk about his work on 20/20, CNN, and Fox & Friends, and he is a consultant for and part of a museum exhibit about mathematics that has been traveling the country since opening at the Smithsonian in spring 2012.

He has been associate director of the Institute for Pure & Applied Mathematics at UCLA; Winship Distinguished Research Professor in the Department of Mathematics & Computer Science at Emory University; a postdoc at the Swiss Federal Institute of Technology in Zurich (ETH); held visiting positions at Université d’Artois and Université Paris-Nord in France; and been a Gambrinus Fellow at TU Dortmund.

My current position has no classroom teaching.  At Emory University, I taught 3 semester-courses per year, on a wide variety of subjects, ranging in level from freshman calculus to courses for advanced PhD students.  The most popular of these was the freshman course on cryptology that I designed.  For several years, I also co-taught the senior course in mathematical economics.
