CMU Geosciences News - New Geo Faculty!

Welcome Marion McKenzie, PhD!

We’re delighted to welcome Dr. Marion McKenzie to the CMU Geosciences faculty! Dr. Marion McKenzie is primarily interested in subglacial processes and the ways in which records left at Earth's surface can tell us about ongoing process beneath modern ice sheets. She uses a wide range of tools including but not limited to GIS mapping, machine learning, sedimentology, geochronology, and geochemistry in her exploration of Earth's icy history. Her research has taken her to remote polar landscapes in places like Alaska and Greenland. 

In the classroom, Dr. McKenzie brings the same curiosity and sense of discovery to her teaching. She recognizes that students arrive with different experiences and backgrounds, and she sees those perspectives as an opportunity to enrich exploration and learning. By meeting students where they are and connecting course material to the physical world around them, she helps make Earth science accessible, relevant, and exciting for everyone.

 Dr. McKenzie welcomes conversations with our students. "If you’d like to chat about icy science or just want to say hello", swing by her office: Wubben 136A (Dr. Tellez's previous office!).

Welcome Morgan Lewis, PhD!

We’re thrilled to welcome Dr. Morgan Lewis, to the CMU Geosciences faculty! Dr. Lewis brings Earth and planetary science to life through hands-on demonstrations, current events, and real-world examples in courses ranging from groundwater and structural geology to weather and climate. She loves inspiring students to explore the natural wonders of our home planet—and our neighbors across the Solar System.

Her research takes her "all the way to Mars", where she uses data from the Curiosity rover to investigate how rocks fracture, whether groundwater once moved through those fractures, and what they reveal about the Red Planet’s geological and hydrologic history. From Earth to Mars, Lewis explores the fascinating intersection of structural geology and low-temperature geochemistry, uncovering how physical and chemical processes shape the rocks—and stories—they leave behind.
