Alexa Fredston-Hermann

PhD Student, Bren School of Environmental Science & Management

I entered the Bren PhD program in 2014 co-advised by Ben Halpern and Steve Gaines. I study the effect of climate change on species distributions. I am working to predict how biogeography, species interactions, habitat, and abiotic factors may limit or promote the redistribution of species experiencing climate change. To study these dynamics, I'm planning to analyze large datasets on species occurrences with a synthetic approach. I'm also very interested in data science and big data analysis in R.In the first year of my PhD, I also participated in a SNaP (Science for Nature and People) working group at the National Center for Ecological Analysis and Synthesis called "Ridges to Reef Fisheries" that studied the impact of anthropogenic runoff on coastal marine ecosystems. Prior to entering the PhD program I worked for Environmental Defense Fund's Pacific Oceans Team as a High Meadows Fellow, and graduated from Princeton University in 2012 with a degree in Ecology and Evolutionary Biology.
