Ezra Zimble, ’22, Undeclared
I studied nitrogen fixation in New Jersey forests as an extension of research conducted in Canada by my supervisor, Romain Darnajoux. We applied his work in boreal forests to New Jersey’s temperate forests by investigating whether nitrogen-fixing bacteria were present and, if so, the conditions that favor nitrogen fixation. My jobs included collecting samples such as mosses, tree bark and soil, then analyzing them in the lab. Over the course of the internship, I gained proficiency in using lab equipment such as gas chromatography and learned about the safe handling of chemicals. Additionally, my supervisor and I discussed experimental design at length before our weekly experiments and proper data analysis afterward. I plan to incorporate the sensitivity to detail in experiment design and analysis I learned to my future research at Princeton.
