We have a few surprises for our season 1 finale featuring Dr. Kaj Johnson, a geophysicist studying earthquakes remotely. Hear about Kaj's journey into the field, the connection between show choirs and teaching, listen in on a couple of potential new segments he promotes (including a drink of non-choice and a friendly competition), hear from a couple of new voices with familiar names - Cari Metz (our producer) and Betsy Leijas (our technical board operator), and stick around for Walther's Outlaws...

Dr. Arndt Schimmelmann joins us today, a geochemist focusing on organics in both natural systems and when developing lab standards. Listen in to hear about a couple of close calls in the lab, exciting field work in caves and lakes in Vietnam, his well-known reference materials program (including a range of standards from foods to hydrocarbons to caffeine!), and his views on the current state of the public trust in science.

On the show today is Dr. Claudia Johnson, a geobiologist studying ecosystems of the past and present to understand what adaptations things like corals have made to survive environmental changes over geologic time. Hear about coral reefs and coral farming (or growing baby corals to then place in various spots in our oceans), the role of reefs in our daily lives (even when we don't realize it, like for fisheries, hurricane protection, and the global economy), how we are always evolving as learners...

Joining us today is Dr. David Lilien, a glaciologist studying glaciers and ice sheets and how ice moves. Learn about party ice - popping and fizzy glacier ice, how ice flows and moves (and how we measure it!), what goes into a field excursion to study ice (like in Antarctica or Greenland), and mushroom hunting!
Apr 11, 2025•44 min•Ep. 14
Joining us today is Dr. Chanh Kieu, an atmospheric scientist using modeling and machine learning to understand weather phenomena, particularly hurricane intensity and prediction. Listen to learn more about all that goes into weather prediction (and be thoroughly impressed that we can do what we can in that field!), the role of AI (artificial intelligence) in improving weather predictability, how you can think of training a model as building with LEGO bricks, and his transition from growing up in...

On today's show we have Dr. Elizabeth Kenderes, an igneous petrologist interested in the stories that lavas and igneous rocks may tell about how or why a volcano erupted (or didn't!). Hear about some weird volcanoes that drew her into the field as a student, what makes a good gemstone for jewelry, underground mines and drilling blast holes, and fluid inclusions - literal pockets of fluid trapped in solid, crystallized rock!
Mar 28, 2025•43 min•Ep. 12
On the show today is Dr. Simon Brassell, a molecular biogeochemist who specializes in organic matter and isotope geochemistry. Hear about his revolutionary work that has earned him the nickname "the Godfather of alkenones", his experiences at sea (including finding out about 9/11 while on a research cruise), the current uncertainties with US-based research cruises moving forward, and his favorite British cuisines.

We are back for the second half of our first season! Joining us to kick things off is Dr. Paul Goddard, a climate scientist and modeler who looks at how Earth may react to CO2 emissions and how we may combat some of those changes. Hear about geoengineering, or large-scale attempts to counteract anthropogenic climate change, Cincinnati chili (a warm-spiced chili with things from cinnamon to chocolate - but so, so good!), and a new way to think about golf course design. You can find more about Pau...

On our midseason finale we hear from Dr. Brian Yanites, a geomorphologist looking at how changes on Earth's surface can impact or are impacted by people, weather, animals, and even ore deposits. Learn a little bit about the history of topography, how the geosciences incorporates drones and lasers (and a time when the drones weren't very well received by some folks on the ground), and his time pre-geomorphology as a collegiate athlete playing football.
Dec 27, 2024•38 min•Ep. 9
Joining us today is Dr. Cody Kirkpatrick, a meteorologist who is interested in weather phenomena and related events. We hear about the Golden Guide that set his course, some aspects of storm chasing (and storm watching), and his passion and skill for sports analytics and prediction (apologies in advance to any Auburn fans that may listen).
Dec 20, 2024•43 min•Ep. 8
Joining us today is Dr. Jackson Njau, a paleoanthropologist working to understand how early humans evolved and why. Hear about his work in Olduvai Gorge, a key anthropology site in Tanzania, how our brains have grown over time (as hard as that may be to believe sometimes), and a favorite dish of his - Ndizi.
Dec 13, 2024•43 min•Ep. 7
Today we get to know Dr. Travis O'Brien, a climate scientist who looks at and models extreme weather and other climate phenomena that could impact our day-to-day lives. We get to hear about some of his more recent work, including using climate models, his time at a national lab and how that works, and a really interesting time living on an alpaca ranch.
Dec 06, 2024•38 min•Ep. 6
Joining us today is Dr. Ed Herrmann, a microbiologist by training who is a geoarchaeologist by way of the pharmaceutical industry and beer brewing. His geoarchaeology work draws on and builds from his experience and time in both of these seemingly unrelated fields that makes for a really exciting and unique perspective.
Nov 29, 2024•49 min•Ep. 5
Listen in today and get to know Dr. Julia Kelson, a sedimentary geochemist looking at past Earth climates. Julia talks us through how she entered the field (you might say it runs in the family), some of her field experiences, and a bit about what work is like in the lab.
Nov 22, 2024•32 min•Ep. 4
Today Dr. Michael Hamburger, an earthquake seismologist and hazards specialist, joins us. We'll hear about his atypical journey into the geosciences, some incredible field experiences, and his time rubbing elbows with some of the Who's Whos of the climate world.
Nov 15, 2024•46 min•Ep. 3
Today we get to chat with Dr. Andrea Stevens Goddard, a low-temperature thermochronologist (and proud Hoosier!) looking at how sediment is moved and stored in geologic basins.
Nov 08, 2024•35 min•Ep. 2
Welcome to Earth on the Rocks with your host, me - Dr. Shelby Rader! On this episode, we dive in to what to expect for the rest of the season and hear a bit about how I ended up in the field.
