James M. DeGraff

James M. DeGraff serves as a Research Professor in the Department of Geological and Mining Engineering and Sciences at Michigan Technological University. A Michigan Tech alumnus with BS and MS degrees, he also earned a PhD from Purdue University. After a distinguished career in the hydrocarbon industry with ExxonMobil, he returned to his alma mater to advance research and education in structural geology and reservoir characterization.

His academic credentials include:

• PhD in Geology, Purdue University
• MS in Geophysics, Michigan Technological University
• BS in Geology, Michigan Technological University

Dr. DeGraff's research centers on structural geology, tectonics, and fracture mechanics, particularly in the Midcontinent Rift System. He investigates fracture network formation, deformation timing, and fluid flow, integrating field, geophysical, and modeling approaches. His work bridges fundamental geological processes and practical applications in reservoir engineering, with a growing focus on automated data analysis techniques.

Analysis of his recent publications (2018-2025) reveals a consistent focus on the Keweenaw fault system and Midcontinent Rift, utilizing LiDAR, aeromagnetic, and seismic data to unravel structural evolution and fracture patterns. This research has significant implications for understanding rift dynamics and optimizing hydrocarbon recovery in fractured reservoirs.

Committed to education, Dr. DeGraff trains future geoscientists and has led research teams in industry and academia. His collaborative projects with reservoir engineers at ExxonMobil addressed complex fracture reservoir challenges, demonstrating the value of interdisciplinary approaches.

He currently leads research initiatives at Michigan Tech that integrate field studies, geophysical data, and computational modeling to solve geological problems, continuing his legacy of impactful science and mentorship.
