Climate pic

Dr. Peter Marra, professor and researcher of Environmental Biology at Georgetown, joined other climate change experts at the university in emphasizing the danger that climate change poses to life on earth. In arguing for action on climate change, Marra invoked Pope Francis’ Laudato Si’ encyclical about the moral and spiritual importance of environmental justice. As an expert on the conservation of birds and other animals, Professor Marra’s research makes it clear that habitat loss and climate change will cause irreversible damage to the world’s ecosystems.

Joseph H. Neale, Professor of Biology at Georgetown demonstrates the importance of NAAG, a peptide neurotransmitter that is widely present in our nervous system. He concludes that drugs that inhibit NAAG inactivating enzymes lead to pro-cognitive effects through activation of NAAG. His paper has inspired future research to understand the effect of NAAG and glutamate carboxypeptidase inhibitors on higher cognitive processes such as learning, memory formation, and attention.

Ries butterfly quote

Dr. Leslie Ries, along with researches from Oregon State University, Ohio lepidopterists, and Michigan State University, analyzed more than 24,000 butterfly surveys contributed by trained citizen scientists from 1996 through 2016. They discovered and published in PLoS ONE, the fall of the butterfly population in one Ohio area that provides a baseline for overall trends in the insect population. The data from Ohio estimated population trends for 81 butterfly species and found three times as many species were trending downward as upward. Dr. Ries helps run one of the longest existing systematic insect-monitoring programs in North America.

article on Armbruster research

Davis Family Distinguished Professor Dr. Armbruster has been studying mosquitoes for over 30 years now. His newest project about the insect revolves around studying the genes that make mosquitoes bite in the first place. Armbruster is essentially trying to recreate the natural biting patterns of the yellow fever mosquito, then pinpointing the exact genes for the ‘biting behavior’. His research has the potential to eliminate the spread of deadly diseases that transmit through the bite of mosquitoes.

Niteace Whittington

Everyone has heard of the scientific method. Many scientists have performed the scientific method over and over, designing experiments and analyzing data. However, a major part of the method that many people over look is to report results. Scientists across the world live on reading research and understanding past studies done. Without reporting results, the entire experiment loses its value. Niteace Whittington has mastered the art of reporting scientific results and was recognized for the best poster on her work for her Ph. D. dissertation.

Amy Battlocletti, Grad student
