- GY 5030
Advisor: David Polly
Research project: My research interests include evolutionary morphology, evolutionary rates, species diversification, integration and modularity.

Henry Z. M. Fulghum
M.S. Student
- hfulghum@iu.edu
- GY 5040
Advisor: David Polly
Research interests: I'm broadly interested in the evolution of early mammals, and more specifically the impact of functional morphology and ecological traits upon their evolution.

Jake (James) Gearon
Ph.D. Student (Edmonds Group)
- jhgearon@iu.edu
- 240-620-5681
- GY 4036
Advisor: Doug Edmonds
Research Interests: I am a sedimentologist focused on marrying big-data analytics, remote sensing, geostatistics, and sedimentology.









Matthew Koelbel
MS Student
- mkoelbel@iu.edu
- GY 4041
I'm interested in the evolution of East African hominins, specifically studying the dentognathic morphology of their fossilized skeletal remainsAdvisor: Jackson Njau

Thomas LaBarge
Ph.D. Student
- tlabarge@iu.edu
- GY 5030
Advisor: Jackson Njau
Research Interests: I am interested in the ecology of the large predators of the Serengeti ecosystem (Lions, Leopards, Hyenas, Crocodiles, etc.) and understanding how their diets and habits have changed over geologic time.

Heather Lawson
Ph.D. Student
- helawson@iu.edu
- IGWS
IGWS advisor: Arndt Schimmelmann
Research Project: My research project aims to concisely define the correlations between the material properties of the mined seam and the stratigraphic risk factors for dynamic failure. Dynamic failure is the name used to refer to a dangerous type of ground failure occurring in underground mines that results in mine worker injury.

Tony Li
Ph.D. Student
- twli@iu.edu
Advisor: Ben Kravitz
Research interests: I came to IU in the fall of 2020 as a graduate student in Mathematics. During the past semester, I started taking classes in the Earth and Atmospheric Sciences department, originally intending to minor in EAS.

Advisor: Paul Staten
Research project: I work with Dr. Paul Staten on climate variability and clouds using satellite data from legacy instruments such as AVHRR and HIRS.


Lan Luan
Ph.D. Student
- lanluan@iu.edu
- GY 4053
Advisor: Paul Staten
Research project: My research focuses on studying the structure of tropical tropopause layer.

MS Student
Quaternary Stratigraphy and Geochronology Laboratory Technician
- gmariett@iu.edu
- 812-855-3951
- IGWS 3014
Advisors: Jose Luis Antinao and Henry Loope (IGWS)
Research interests: My research is centered around the geochronology of northern Indiana's glacially derived geomorphic features and the increased precision of OSL/IRSL dating via statistical modeling.

Harrison Martin
Ph.D. Student
- hkmartin@indiana.edu
- GY 4030
Advisor: Doug Edmonds
Research project: I use drone-based lidar to measure changes caused by floods in river landscapes.




Danielle Peltier
Ph.D. Student
- dpeltier@indiana.edu
- GY 5055A
Advisor: Ed Herrmann/Jackson Njau
Research project: I study the East African Rift System climate, volcanism, and landscape change, and how these ecological changes drove hominin evolution and behavior.

Ph.D. Student
- ktquagra@iu.edu
- GY 4037
Advisor: Travis O'Brien
Research Project: Atmospheric Rivers detection, attribution, and morphology using climate models and ARTMIP catalog.
