Faculty & Staff
Dr. Marissa Tremblay (she/her/hers)
Marissa is the PI of Thermochronology @ Purdue. She is an Assistant Professor in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue. Learn more about Marissa's background and research interests here.
Devin Blair
Devin is a Scientific Research Associate at Purdue, splitting her time between the Purdue Rare Isotope Measurement (PRIME) laboratory and the Thermochronology @ Purdue noble gas spectrometry facility. She earned her BS in Geology & Geophysics from Purdue in 2022 and her MS in Applied Geospatial Analytics from Purdue in 2025. She has a background in chromatographic vitamin analysis via HPLC and LC-MS methods using chemical assay testing. She is excited to learn more about and contribute to the ongoing research on noble gases and short-lived radionuclides.
Dr. Eric Dziekonski
Eric has a background in home-built and customized mass spectrometry instrumentation and is extremely interested in the various technologies and methodologies associated with isotopic measurements. He is excited to learn how these measurements relate to the materials history and how that impacts our understanding of terrestrial and cosmological evolution.
Dr. Ryan Ickert (he/him/his)
Ryan is a Senior Research Scientist at Purdue who spends most of his time in the Radiogenic Isotope Geology Lab but will occasionally help with projects in Thermochronology @ Purdue. He is extremely excited to add to the growing body of literature on the neon isotopic composition of air!

Wenbo Zhan (he/him/his)
Wenbo is a PhD student in T@P. He is interested in geochemistry, tectonics, and geomorphology. Specifically, he applies apatite 4He/3He and (U-Th)/He thermochronology to study upper crustal tectonics, landscape evolution history, and their correlation to the lower crustal and mantle dynamics. He is also interested in the development of thermochronology methods, such as the study of noble gas diffusion kinetics in minerals.
