Q&A with Josh Smith
Q: Can you tell us about yourself and your role at PRI?
A: My research interests revolve around ore deposit formation and applying analytical tools and techniques to mineral exploration programs, especially isotope geochemistry and reflectance spectroscopy. I primarily manage the Isotope Geochemistry Lab for the U of I Department of Earth Science & Environmental Change and serve as a Research Affiliate with the Critical Minerals group at ISGS.
Q: What drew you to your area of work or study?
A: As a college freshman, I took a required geology course and realized it was a pathway into the mining industry. From there, I discovered my interests in mineral exploration and isotope geochemistry through various classes, projects, and field trips.
Q: What tools are indispensable to your work?
A: My work relies heavily on mass spectrometers like our multicollector ICP-MS, quadrupole ICP-MS, and gas source instruments for light stable isotope work. Reflectance spectroscopy is also essential for identifying hydrothermal alteration minerals in the field.
Q: What questions do you get asked most frequently about your career? How do you answer those questions?
A: I often hear, “So, what exactly do you do?” I manage an analytical geochemistry lab on campus, where I prepare and analyze samples and train students and other users to work in the lab. Occasionally, I also teach a course on mineral deposit formation.
Q: What advice would you give to those just starting out in your field?
A: Enthusiasm goes a long way when it comes to getting jobs in the mining industry. Showing genuine interest is just as important as good grades and research experience. Anyone interested in the field is welcome to take my Ore Deposits course, which will next be offered in Spring 2026!
Q: What do you do in your free time?
A: I enjoy woodworking and home improvement projects. Most of my free time is spent with my wife and twin boys. We live in St. Joseph and love taking walks on the Kickapoo Rail Trail and traveling through Illinois and Indiana to visit family.
