Dr. Richard Gaschnig
I am an Associate Professor in the Department of Environmental, Earth and Atmospheric Sciences at the University of Massachusetts Lowell. I specialize in geochemistry, geochronology, and petrology. At UMass Lowell, we have a Q-ICP-MS, laser ablation unit, and ICP-OES, along with a wet lab for sample digestion and column chromatography. With LA-ICP-MS, we regularly perform combined U-Pb and trace element analysis of zircon, monazite, rutile, and titanite and are working on expanding to other minerals.
I was coauthor on a paper in PNAS on the use of vanadium isotopes to understand the evolution of the continental crust. Interview on it here
Grad student Ericka Boudreau and I were interviewed by Nick Zentner on his popular geology explainer YouTube series: LINK
In the summer of 2022, I ran a field geology course in Glacier National Park and eastern Idaho; this was supported by an NSF grant. Read about it here.
I was fortunate to see the 2021 eruption in Iceland. Videos
Congratulations to Cass Stegner, Sam Marshall, Ericka Boudreau, and Dina Mato for successful MS defenses
