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.

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!

Postdoctoral Researchers

Dr. Hongcheng Guo (he/him/his)

Hongcheng earned his PhD from Lehigh University in 2022, and joined Thermochronology @ Purdue in January 2023. He is interested in tectonics, surface processes, and their interactions with climate. His training has focused on tectonic processes, noble gas geochemistry, and geomorphology with particular attention on low-to-medium temperature (U-Th)/He and ⁴⁰Ar/³⁹Ar thermochronology.

Graduate Students

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.

Matias Romero (he/him/his)

Mati is a PhD student in the Department of Geoscience at the University of Wisconsin Madison and is co-advised by Dr. Shaun Marcott and Marissa. Mati is using cosmogenic nuclides, including cosmogenic ³He, to reconstruct the glacial history on volcanoes in the Southern Volcanic Zone of the Chilean Andes.
