    The Geologist's License: How the FG and PG Exams Get Built — with Keith Rapp

    30/04/2026 | 1h 3 mins.
    In this episode, we sat down with Keith Rapp, senior hydrogeologist, longtime volunteer with ASBOG (the Association of State Boards of Geology), and immediate past president of the organization. We dug into the professional geologist licensure process — what the FG (Fundamentals of Geology) and PG (Practice of Geology) exams actually test, how questions get written and vetted by panels of subject matter experts, why some states require licensure and others don't, and why Keith argues that licensure is fundamentally about protecting public health and safety.
    Keith walked us through his path from growing up in Duluth with a geomicrobiologist uncle, to a master's in hydrogeology at Baylor, to a career cleaning up contaminated sites using microbes — what he calls hydrogeomicrobiochemistry. We talked about his current work on PFAS bioremediation, the idea of "pushing evolution" by engineering biofilm environments where microbes can adapt to degrade forever chemicals, and the role of zeolites as remediation media.
    We also got into the practical stuff students and early-career geologists actually want to know: how to study for the FG exam, why test scores point you toward weak domains, what reciprocity between states looks like, the difference between an ASBOG license and an AIPG Certified Professional Geologist (CPG) designation, and why writing skills still matter in a hiring pile. We closed with a conversation about AI in geoscience — where it helps, where it gets you in trouble when your name is on a signed report, and how the profession should think about it going forward.
    If you're a student preparing for the FG, a working geologist thinking about getting licensed in another state, or just curious about how a professional credentialing system gets built and maintained, this one is for you. The ASBOG annual meeting is in Hershey, PA this October — open to anyone interested in the profession.

    What is a Professional Geologist? An Intro to Licensure

    26/03/2026 | 31 mins.
    Jesse and Dr. Joshua Davis introduce a new series on professional geology licensure, prompted by listener questions, exam study use of their podcast, and continuing-education approvals. Jesse shares starting the U.S. process by taking the FG (Fundamentals of Geology) exam and explains the typical U.S. pathway in 31 states: FG exam, geologist-in-training status, years of work experience under a licensed geologist (with some state-dependent education carve-outs), then the PG exam and references. Josh contrasts Canada and the UK, noting the UK’s Chartered Geologist is less central, while Canadian systems are province-based and may restrict the “geologist” title; Quebec lacks an academic carve-out and requires supervised experience plus an exam. They discuss rationales for licensure—public protection, minimum geology competency amid changing degree names, professional trust, insurance coverage, employability, and continuing education.

    Visualizing the Deep Earth - CEO and Founder Christie Capper

    19/03/2026 | 53 mins.
    Today Jesse talks with Christie Capper, founder and CEO of Deep Earth, which aims to visualize the subsurface by digitizing and unifying scattered underground data into accessible 3D maps. Christie describes her path from a toy-inventor upbringing to studying economics and mechanical engineering (robotics) at Claremont and Columbia, then working at SpaceX, interning at the UN and Boeing, moving into early-stage VC in Europe, and joining a fusion startup. Work in carbon removal and geothermal led her to subsurface problems; mining research highlighted boom-bust cycles and long development timelines, motivating a broader focus on faster-feedback markets like water, geothermal, utilities, and construction. She discusses pre-seed funding, network-driven early hires, first paying customers, lessons on pricing and execution, and how investor rejection sharpened the company’s focus.
