Johnson Haas

Johnson Haas serves as Associate Professor of Geochemistry and Planetary Science within the Department of Geological and Environmental Sciences at Western Michigan University, maintaining his office in 1129 Rood Hall with direct contact at (269) 387-2878.

His academic foundation includes:

• Ph.D. from Washington University (1993)
• B.S. from Auburn University (1988)

Dr. Haas's research program centers on aqueous geochemistry and geomicrobiology, specifically investigating thermodynamic properties of uranium oxide reactions critical for nuclear fuel cycle management and high-level waste disposal. His work examines bacterial interactions with toxic metals including uranium, arsenic, chromium, and rare earth elements in natural environments, bridging planetary science with environmental remediation challenges.

While leading active research in nuclear geochemistry and biogeochemical cycling of contaminants, the available documentation does not specify grant funding sources, student mentorship activities, or dedicated laboratory facilities.
