Mathematics of the Tree of Life: From Genomes to Trees and Beyond

ABSTRACT: The reconstruction of the Tree of Life is an old problem in evolutionary biology which has benefited from various branches of mathematics, including probability, combinatorics, algebra, and geometry. Modern DNA sequencing technologies are producing a deluge of new data on a vast array of organisms—transforming how we view the Tree of Life and how it is reconstructed. I will survey recent progress on some mathematical and computational questions that arise in this context.

BIO: Sebastien Roch is an Associate Professor in the Department of Mathematics at University of Wisconsin-Madison. He earned his Ph.D. in Statistics from the University of California, Berkeley under the guidance of Elchanan Mossel. From 2007-2009, he was a Postdoctoral Researcher at Microsoft Research. From 2009-2012, he was an Assistant Professor in the Department of Mathematics at the University of California-Los Angeles. He was a Kavli Fellow of the National Academy of Sciences in 2014 and he is the recipient of an NSF CAREER Award and of an Alfred P. Sloan Fellowship. His research interests lie at the interface of applied probability, statistics, and theoretical computer science — with an emphasis on biological applications, notably mathematical phylogenetics.

All QBio sponsored talks take place on Wednesdays at 2:00 p.m. in the 3rd floor Orchard View room of the Discovery Building. Talks are open to the public. Access to the room is via the elevator behind Aldo’s Cafe in the Northeast corner of the building.
