Dr. Katrina Menard is an entomologist, so she studies bugs (someone has to, right??). She was in Black Mesa this summer as part of the ExplorOlogy program. She was teaching the students how to develop a scientific study by taking a census of the local insect population.
So why entomology and why insects? Well at the 1:10 mark she explains what led her to a career studying the tiniest of creatures. At the 1:48 mark she talks about the importance of funding for scientific research and why the decision makers need to look at the long term results.
