About me:

Where did you grow up?

I grew up in Vermont on the shores of Lake Champlain

What are the specifics of your educational background?

My PhD thesis presented a novel graph-theoretic model called multi-node graphs where edges are activated or deactivated as a function of the state of their incident vertices. Such graphs are useful for modeling biological networks and for optimizing constraints in multiplex PCR assay design.

What is your research focus in a bit more detail?

My current research is focused on the development of scalable multi-objective optimization and decision-support systems using evolutionary algorithms.
