Cadence Miller<\/h2>\n\n\n\n

PhD Student in Environmental Science with a Concentration in Chemistry<\/p>\n\n\n\n

Cadence received his bachelor’s in chemical engineering and chemistry in Spring 2024, and is now a first year Ph.D. student working in the Gru Lab. Their research primarily focuses on fundamental properties of molecules such as quantum tunneling in 3-methylstyrene using microwave spectroscopy. He is also interested in pursuing the identification of relevant molecules in the interstellar medium that can provide insight into the atmospheric chemistry on Earth.<\/p>\n\n\n\n
