Title: From phylogenetics to algebraic geometry
Abstract: Many of the evolutionary models used in phylogenetics can be viewed as algebraic varieties. In this expository talk we will explain the main goals of phylogenetics, introduce evolutionary Markov models on trees, and show how algebraic varieties arise in this context. Moreover, we will see how an in-depth geometric study of these varieties leads to improvements on phylogenetic reconstruction methods. We shall illustrate these improvements by showing results on simulated and real data and by comparing them to widely used methods in phylogenetics.
The colloquium will take place in Mott Lecturer Theatre in the Physics Building at 16.00-17:00 on Wednesday 12th December. It will be followed by a drinks reception in the Maths Common Room.
