Evolution and fitness of S. cerevisiae in fluctuating environments
I'm interested in the physiological and evolutionary consequences of fluctuating environments.
Check out our paper (led by Clare Abreu) on fitness in two-environment fluctuating cycles out in Nature Ecology and Evolution here!
My ongoing work focuses on characterizing the nature of envionmental memory effects, the length of these effects, and their consequences for evolution in temporally ordered environments. I am also working on testing the generality of these results using a collection of natural yeast isolates.
Natural variaiton and resource Allocation in Fluctuating Environments
Using models and experimental techniques, I am studying how yeast natural isolates allocate resources in fluctuating conditions, particularly in the context of the carbon hierarchy.
Combinatorics of Phylogenetic Trees
In my rotation in the Rosenberg lab we generalized an algorithm to count the labeleld histories (a useful mathematical property of phylogenetic networks) for phylogenetic trees to galled trees, a class of phylogenetic networks.
