Marek Locmelis is an associate professor in the Department of Earth and Planetary Sciences and the Bureau of Economic Geology in the Jackson School of Geosciences at the University of Texas at Austin. He is an economic geologist with expertise in geochemistry, petrology, planetary evolution and analytical chemistry.

His research focuses on the genesis of magmatic, hydrothermal and sedimentary ore deposits and the development of novel mineral exploration strategies. Locmelis' research also investigates pathways towards increasing the domestic supply of critical minerals, including the enhancement of critical mineral recovery from existing production streams, reprocessing of historic mine waste materials, and through improving economic geology-related STEM education.

Locmelis is a fellow of the Society of Economic Geology (SEG) and the Chair of the SEG Graduate Student Fellowship Program. He received a 2014 NASA postdoctoral fellowship award to investigate the processes that control the toxicity/habitability of planetary atmospheres and a 2020 National Science Foundation (NSF) CAREER award for his research on translithospheric metal transport by magmatic-hydrothermal fluids.

Prior to joining UT Austin in August 2024, he was an Assistant and then Associate Professor at Missouri University of Science and Technology in Rolla, Missouri (2016-2024) and a postdoctoral fellow at NASA Goddard Space Flight Center in Maryland (2014-2016) and the University of Western Australia, Perth, Australia (2011-2014). Locmelis holds a Ph.D. in Earth and Planetary Sciences from Macquarie University, Sydney, Australia, and a Diploma (MSc equivalent) and Pre-Diploma (BSc equivalent) in Geosciences from the University of Hannover, Germany
