Picture of Dr. Pedro Castro.

Pedro joined the group in April 2021, bringing extensive experience with multi-reference calculations on the dynamics of excited states. He got his Ph.D. in Theoretical and Computational Chemistry from the Universitat Rovira i Virgili, Tarragona (Spain) with Prof. Mar Reguero. He then did a postdoc with Keiji Morokuma at Kyoto University. He is focusing on reactions of mercury-containing radicals with ozone and photochemistry of stable Hg(II) compounds. Check him out on ORCHID, Google Scholar, or ResearchGate.

Before joining our Ph.D. program in January 2017, Weiyao obtained an M.S. at Syracuse University studying the interaction of aluminum with organic matter in soil. He is doing computational modeling of electron beam chemistry.




Lyra Sauer   lsauer 

Lyra is a senior in the Chemistry Department. She joined the group in January 2022 and had nearly completed a survey of the atmospheric fate of gaseous urea.

Darshi Tharika  darshihep
Darshi got her B.S. in Environmental Sciences from the University of Peradeniya (Sri Lanka). She is a second-year Ph.D. student using computational chemistry to investigate atmospheric chemistry of mercury. She is writing up her quantum chemical studies of the mechanisms and kinetics of  reactions of HOHgO radical with atmospheric trace gases. She is finishing up studies of NO3-initiated oxidation of Hg(0).
