Graduate Students

Rachel Pilla Rachel Pilla is PhD student analyzing long-term lake temperature data from around the world in the context of climate change and seasonal changes in abiotic factors such as water transparency, lake temperature, dissolved oxygen, and watershed characteristics. Her research focuses on the ecological consequences of changes in lake thermal structure and the implications for lake ecosystems and services. Rachel is also interested in the effects of lake browning due to increased dissolved organic carbon, and the potential resulting effects on oxygen, temperature, and biota. She completed her Master's degree in the Global Change Limnology Laboratory in 2015.

Nicole Berry
Nicole began her pursuit of a Masters degree in the Global Change Limnnology Lab in Summer 2016. She is interested in the role of DOM as a biotic and abiotic driver of aquatic communities. Browning, or an increase in color-absorbing compounds in the water, can impact communities through shading or by serving as a carbon and/or nutrient subsidy. Nicole hopes to study the ways in which these different mechanisms can facilitate the movement of invasive species or vector-borne pathogens into lakes with changing transparency and dissolved organic carbon inputs.


Lauren Adkins

Lauren Adkins, who began working on her PhD in Fall 2016, plans to study the effects of climate change and changing transparency on lake phenology, mixing, and nutrient regeneration. Lauren is also interested in studying the public health and socioeconomic consequences of those changes on communities relying on the lake for goods and services.
