    Craig McClain: Deep-Sea Biology, Dollar General, and the Finger of God

    Deep-sea biologist Dr. Craig McClain grew up in the Arkansas Ozarks, the son of a barbed-wire factory worker and a waitress-turned-teacher. His bedroom walls were papered with National Geographic maps. Today he studies some of the strangest animals on the planet, from giant isopods to furry-armed yeti crabs, and runs a lab at the University of Louisiana at Lafayette that deliberately recruits students from working-class backgrounds. Amy and Craig met on a panel at the Association of Science Communicators conference and bonded instantly. In this conversation, they dig into why a stint as an assistant manager at Dollar General might be the best preparation for grad school, how Craig's Southern accent became a science communication asset, and what it really looks like to monitor the Deepwater Horizon site a mile and a half below the surface. They also cover why scientists need to stop treating the public like empty vessels, why every profession has jargon (six stack, anyone?), and whether aliens are hiding in the deep sea. Spoiler: the deep sea doesn't need them to be weird. Craig closes with a plea: the deep ocean may be our last chance to get one habitat right, and that chance is shrinking every year.

    Commercial Diving in Alaska with Jo Hartwig of Highmark Marine

    Jo Hartwig didn't grow up dreaming about commercial diving — she was working three jobs and going nowhere fast when her dad's old stories about naval shipyard divers stuck in her head. Nine months later she was underwater for the first time. Nearly a decade after that, she's the Dive Supervisor and Project Manager for Highmark Marine Group, running dive crews out of Kodiak, Alaska. In this episode, Jo takes us inside a trade most people have probably never thought about, let alone understood. She explains why an ROV still can't replace a human diver, what it's actually like climbing a ladder in a 30-pound helmet after your dry suit springs a leak, and how she reads her divers' breathing to know when hypothermia is setting in before they do. We get into the physics of the bends, the electrochemistry keeping steel boats from dissolving in saltwater, and — because we couldn't let her go without asking — how underwater welding actually works. Even after her explanation, Amy's brain can't handle it. Highmark's work reaches further than most people would guess, from patching Coast Guard vessels mid-emergency to building platforms for SpaceX's Alaska launches. Jo also opens up about breaking into a male-dominated trade, the mindset it takes to stick with a hard-to-master skill, and what she wishes people understood before writing off a career underwater.

    Behind the Glass: Life support systems at Tennessee Aquarium

    Twelve thousand animals. Four buildings. One crew that monitors all of it, 24/7. This week we're talking to TWO staff members from Tennessee Aquarium in Chattanooga, Sean Hill and Kyle McPheeters. They represent the aquarium's Life Support Systems team. In other words, the folks behind the scenes keeping the habitats of alligators, penguins, sharks, and thousands of fish healthy and safe. We dig into what "life support systems" really mean in an aquarium setting, why saltwater is brutal on equipment, how sharks breathe (spoiler: not all of them have to keep swimming), and what goes into designing a 6,000-gallon reef exhibit from the ground up. We also talk about the Aquarium's Lake Sturgeon reintroduction program, what it's like getting the 2 a.m. alarm call when something's wrong with a tank, and the moment Sean became one guest's hero for "rescuing" an upsidedown — (and according to Kyle, very sleepy) — touch tank animal. It's a great look at the blue-collar backbone behind an institution most people only see from the visitor side of the glass.

    Blue Collar jobs at NASA? Veteran Chad Cleary's Story

    Blue Collar White Coat is back for Season 2 — and we're kicking things off on location with NASA Ames Facility & Maintenance Manager Chad Cleary, who oversees operations for the massive boiler system creating space-like conditions at NASA Ames Research Center's Arc Jet Complex in Mountain View, California. The work done by Chad's team facilitates the researchers testing spacecraft thermal protection systems (heat shields) by blasting materials with plasma streams reaching temperatures over 10,000°F — simulating the extreme heat of atmospheric re-entry. This work directly supports NASA's Artemis II mission, plus commercial partners like SpaceX and Blue Origin. In this episode, Chad breaks down how the somewhat archaic technology of boilers power the state-of-the-art Arc Jet chamber and what it actually takes to certify a spacecraft component as flight-safe. But the real story is how he got there. Chad's path to NASA didn't start with an engineering degree — it started in a Navy boiler room. Ruled out for pilot training and special warfare due to color blindness, he became a machinist mate, operating boilers and propulsion systems on the USS Boxer in 130-degree engine spaces. After leaving the Navy, he worked in industrial steam/electric cogeneration, then pivoted into IoT smart-building lighting systems for high-rises like the Salesforce Tower — before landing a "boiler operator" contractor role at NASA Ames that he almost overlooked because he didn't think skilled trades experience was a way into the space program. He could not have been more wrong! This episode is for: Skilled tradespeople and veterans wondering if a technical trade background can lead to a career in aerospace or science Anyone navigating a military-to-civilian career transition Listeners curious what "working at NASA" actually looks like outside of the astronaut and PhD-engineer stereotypes STEM and space enthusiasts who want the human, hands-on side of spacecraft testing Also in this episode: the Navy's most misunderstood job (machinist mate vs. mechanic), invisible high-pressure steam leaks, transferable skills after military service, and how Chad built a hot sauce brand from his kitchen during COVID. This episode launches a Season 2 arc focused on ocean, aerospace, and skilled-trades careers — including a commercial diver and the life support technicians who keep the Tennessee Aquarium's exhibits alive and thriving.

    The History of Skilled Trades: You won't believe where it all started

    Special crossover episode with Seemingly Unrelated What do medieval guild halls and the first mechanized loom have to do with modern science? In this special crossover episode, Blue Collar | White Coat teams up with Seemingly Unrelated host Andrew Johnstone to explore how knowledge has always been built, shared, and preserved through skilled, often invisible labor. From guild halls and tradespeople to archives and technicians, this conversation traces the human infrastructure that makes discovery — and history — possible. Andrew brings his archivist's perspective (and a talent for sneaking history lessons into great stories) to a wide-ranging conversation about how ideas move through time, who decides what gets preserved, and why so much of the work that underpins science and culture goes unseen. If you've ever wondered how history survives, how trust in institutions is built, or why blue collar work has always been essential to progress — this one's for you.   This episode is a crossover with Seemingly Unrelated, hosted by Andrew Johnstone. Seemingly Unrelated explores surprising connections between history, culture, and the present day — often starting from one small question and spiraling into something much bigger. Andrew is also an archivist, bringing deep firsthand experience with the behind-the-scenes work of preserving history. Andrew also provided historical research support and fact-checking for this episode.

    From Lab to Legislation: Training Scientists to Influence Policy

    In Episode 9 of Blue Collar | White Coat, Amy sits down with Robin Garcia, a former federal worker and now a professional science communications trainer with Compass Science Communication. Robin's career has taken her from marine biology labs to NOAA to Capitol Hill workshops — and in this episode, she breaks down exactly why communicating science effectively to Congress, policymakers, and everyday non-experts is more crucial than ever. We cover everything from shrimp-on-a-treadmill headlines to the realities of federal budgets, policy briefings, fellowships, science education, burnout in research, and why scientists so often struggle to translate their work outside of academia. Robin also shares a behind-the-scenes look at how she prepares scientists to speak with members of Congress and what policymakers actually need from experts when making funding decisions. If you've ever wondered how science moves from the lab bench to the halls of Congress — or why it sometimes doesn't — this episode is for you. What We Talk About in This Episode: How Robin went from marine biology to science communication Life as an aquarium intern, REU fellow, and grad student Crabs on treadmills, blue crabs, and climate impacts on marine species Why many scientists struggle with teaching and communication Working at NOAA, federal contracting, and "the power of the purse" How congressional staffers process scientific information Why scientists need simpler messages — not "dumbed down," just translated How Compass trains researchers to work with policymakers Why people assume science communication equals "media training" The rise of science communication careers in the U.S. Structural barriers to entering science (money, access, equity) Why the loudest anti-science group is not actually the largest What gives Robin hope for the future of science and policy Chapters / Timestamps 00:00 — Intro Amy sets the scene: what Congress funds, why science communication matters, and who actually understands scientific concepts on Capitol Hill. 03:42 — Reconnecting After 10+ Years Robin and Amy share the backstory of how they first met at the National Aquarium. 04:30 — "Shamu Showed Me the Light" Robin explains her early love for the ocean and the path to marine science. 06:30 — College, Chemistry, and Choosing Marine Biology Studying at the University of Miami, double-majoring, and surviving organic chemistry. 07:54 — REUs, Crabs on Treadmills, and Real Field Work A deep dive into research internships, metabolic studies, and why crustaceans need treadmills. 10:47 — Climate, Oxygen, and Estuary Life How environmental change impacts blue crabs, clams, oysters, and coastal ecosystems. 12:12 — The Hardest Job in Science: Teaching Why teaching assistantships are challenging and the difference between "knowing" and "teaching." 14:56 — From Educator to Environmental Research Robin's time teaching beach ecology and working in animal husbandry at NIH. 19:13 — Burnout in Research & Rethinking the Path Why the "aha moments" in science are so rare — and why she pivoted away from research. 20:58 — Discovering Science Communication Volunteering, building a portfolio, and learning how to translate research for non-experts. 23:47 — Joining Sea Grant & NOAA Federal contracting, budget stress, agency priorities, and working with coral reef programs. 26:28 — Palau, Coral Reefs & International Science Policy Behind the scenes of NOAA travel, jurisdictional meetings, and multi-agency collaboration. 27:51 — Who Really Works for the Government (And Why They Stay) IT staff, biologists, and federal workers choosing mission over money. 31:10 — What Compass Science Communication Does Training scientists, preparing fellows, and the key differences between experts and non-experts. 33:26 — Communicating With Policymakers How congressional offices operate, what staffers need, and why one-pagers matter. 36:12 — Bringing the Hill to the Classroom Compass' unique model of bringing in actual policy experts for workshops. 39:23 — How Policy Meetings Really Work Who to email, why contact forms go nowhere, and how to find the right staffer. 41:08 — Flip the Script: Start With the Result Why scientists must reverse the structure of academic papers when addressing the public. 43:52 — Simple, Not Simplistic Using a different "language" instead of dumbing down science. 47:37 — The Reality of Literacy Levels in America Understanding why plain language is essential — without judgment. 49:18 — Fellowships, Science Policy Careers & Early Training How fellowships bridge academia and policy, what they offer, and why they're growing. 55:22 — How Science Communication Has Changed From obscure niche to essential skill — and why communication must be baked into research. 59:08 — The Hidden Financial Barriers to Science Why research often requires unpaid labor and how that shapes who gets to become a scientist. 1:03:13 — Why Scientists Can Be Prickly (And How to Work With Them) The tension between communicators and researchers — and how shared goals help. 1:06:35 — Hope for the Future Why the anti-science crowd is smaller than it appears and how solidarity is growing. 1:08:57 — Closing Thoughts Standing up for science, the power of voting and advocacy, and what's next for the show.
