How long have you been studying/working on insect cold hardiness?
About two years.

What insect(s) do you study?

 Walnut twig beetle, Pityophthorus juglandis Blackman

What is your main research?

My focus is on two important questions: 1) How does cold effect walnut twig beetle and at what temperature does a majority of mortality occur? 2) How suitable are hosts in the eastern U.S. for walnut twig beetle?
