Katherine St. John (Hunter College, CUNY GC, AMNH), Analyzing Evolutionary HistoriesTrees are a canonical structure for representing evolutionary histories. Many popular criteria used to infer optimal trees are computationally hard, and the number of possible tree shapes grows superexponentially in the number of taxa. We choose one popular optimality criteria and address the question of where do turtles fit in the tree of life? The answer is subject to debate. We analyze different hypothesis under the Maximum Parsimony Criteria and discuss why it is computationally hard to find the optimal tree in the general case.

Ethan Akin (City College of New York), Surprising DiceNote the unusual time!
A generalized die is a cube with positive numbers on the six faces, possibly with repeated values. We say that die A beats die B, when the probability that A > B is bigger than 1/2. There exist intransitive dice A, B, C with A beats B and B beats C but C beats A. In fact any pattern of winning and losing can be mimicked using dice although it may require dice with more than six sides.

Heidi Goodson (Brooklyn College), Vertically Aligned Entries in Pascal's Triangle and Connections to Number TheoryThe classic way to write down Pascal's triangle leads to entries in alternating rows being vertically aligned. In this talk, I'll explain and prove a linear dependence on vertically aligned entries in Pascal's triangle. Furthermore, I'll show how this result is related to a problem in number theory. Specifically, I'll explain how a search for morphisms between hyperelliptic curves led to the discovery of this identity.
