I am a graduate student in the Freshwater and Marine Sciences Program at the University of Wisconsin-Madison. Since childhood, I have been shaped by my experiences to appreciate the environment. I grew up exploring woods filled with evergreens, deer, salamanders, snakes, poisonous plants, and wild strawberries. Summers were spent at camp with my sibling where the wilderness was our Terabithia. Now, more of my time is spent wallowing in scientific literature than in the great outdoors, but I strive to maintain that sense of wonder.

The blog

The purpose of definearth is to educate the public about important environmental issues that are applicable to their lives in a clear and concise way. I hope to express the growing world of environmental technology, share current environmental news, and incorporate a little bit of myself into my writing here. The name definearth originates from one of my favorite environmentally conscious movies, Wall-E. 

Current work

My research is centered around wetland gas fluxes measured with the eddy covariance technique as part of Dr. Ankur Desai’s eco-meteorology lab at University of Wisconsin-Madison. As a land grant institution, it is the perfect place to study ecosystems unique to the area such as bog or fen wetlands. You can see one of the field sites that I work on in the blog post titled Allequash Creek Wetland and on the Water@UW-Madison Research Story Map. My job mainly involves dealing with “big data” through data analysis and data visualization with the computer programming language, MATLAB. I am also interested in wetland conservation, management, and cultural value.

Past work

Previously, I worked for the Department of Civil and Environmental Engineering at Syracuse University in Dr. Charles Driscoll’s wet lab. I tested samples from the NSF-funded Ice Storm Experiment in Hubbard Brook Experimental Forest for Dissolved Organic Matter (DOM) and Dissolved Organic Carbon (DOC) with guidance from Dr. Teng Zeng in the Environmental Organic Chemistry lab. I have also done research for the University at Buffalo’s Civil, Structural, and Environmental Engineering Department. There, I studied the efficiencies of solar cookers.

Awards

I was awarded the National Science Foundation’s prestigious Graduate Research Fellowship 2020-2023 to pursue my PhD in Freshwater and Marine Science at UW-Madison. The university press release is here. In 2022, I was selected as an alternate for the Boren Fellowship and a semi-finalist for the Fulbright U.S. Student Program to do independent research in Indonesia. Any opinions, findings, and conclusions or recommendations expressed in this blog are mine and do not necessarily reflect the views of the National Science Foundation.
