Current Biology Graduate Students
I am a Biologist from Colombia doing my Ph.D. in the GDPE Program at CSU in the Stream Ecology Lab with Dr. LeRoy Poff. I am interested in studying ecological traits in stream communities, particularly how trophic networks are built in aquatic ecosystems. I also want to find out how latitude, elevation and climate change affect this structure, and how this all relates to functional diversity in the community.
I study how grasslands respond to altered precipitation patterns as a result of climate change. Specifically, my research focuses on how more frequent deluges (large rainstorms) will affect ecosystem processes in the shortgrass steppe of Eastern Colorado.
I am interested in biogeochemical nitrogen (N) cycling and the N transformations that generate or consume the potent greenhouse gas, nitrous oxide (N2O). I primarily use stable isotopes to address my research questions, which broadly correspond to better understanding the environmental factors that control microbial N2O emissions.
Fourth year graduate student in Dr. Dan Sloan's lab studying the effects of mitochondrial gene loss by utilizing new RNA sequencing technologies and a biological system that is undergoing rapid mitochondrial tRNA gene loss.
