Amirhosein (Amir) Riahi
Postdoctoral Researcher, Kroll Institute of Extractive Metallurgy (KIEM), Mining Engineering Department, Colorado School of Mines

Dr. Amirhosein Riahi serves as a postdoctoral researcher at the Kroll Institute for Extractive Metallurgy at the Colorado School of Mines, where he conducts research on a collaborative NASA project titled Multi-stage Oxygen and Regolith Resource Extractor (MORRE). He specializes in Carbon Capture, Utilization, and Storage (CCUS), focusing on post-combustion CO2 capture methods, particularly using porous solid adsorbents and innovative Process Intensification (PI) techniques. Dr. Riahi’s background spans mining and environmental engineering, materials science, surface and bulk characterization, mine closure and reclamation, mass fate and transport, and numerical and analytical modeling. The findings of his research have been published in prestigious journals, presented at international conferences, and recognized with awards. He has collaborated on numerous domestic and international projects, including consulting for the United States Environmental Protection Agency (EPA) on a project related to the pore textural properties of biochar for enhancing environmental remediation. In 2016, he interned at Clausthal University of Technology in Germany, contributing to a collaborative mineral processing project with Mercedes-Benz. He recently co-authored a $2M DST-NSF joint project proposal, Developing Green Bio-Carbon Blends for Sustainable Metal Oxide Reduction and Metal Recovery. Additionally, he co-authored a patent on Resonant Vibratory Mixing for Improved Samarium–Cobalt Magnet Leaching and secured a five-year, $350,000 grant from the U.S. Department of Defense Combat Capabilities Development Army Research Laboratory (ARL) for a project on biomass power generation at Montana Technological University. Dr. Riahi is an active member and speaker in professional organizations, including the Society for Mining, Metallurgy, and Exploration (SME), the American Chemical Society (ACS), the International Association for the Exchange of Students for Technical Experience (IAESTE), and the graduate student advisory board at Montana Technological University.
