Kristof Richmond

Kristof Richmond

Principal Investigator; CTO, Sunfish, Inc.

Kristof Richmond is the Chief Technology Officer of Sunfish, Inc., and the principal investigator for the Our Submerged Past expedition. Growing up in Colorado, he didn't have much experience with the ocean, but caught the marine robotics bug working on automating some capabilities for remotely operated vehicles (ROVs) from MBARI (the Monterey Bay Aquarium Research Institute) during graduate school (despite constant battles with seasickness!). He completed his Ph.D. at Stanford University on a visual mapping, navigation, and control system for the MBARI ROVs and then started working with Stone Aerospace on a variety of robotics projects, almost all with an underwater component. He's taken advanced, highly maneuverable underwater robots into all kinds of places, from caves in Namibia to under the McMurdo Ice Shelf in Antarctica. He has been involved with the development of the highly maneuverable autonomous underwater vehicle SUNFISH® from its beginnings at Stone Aerospace, and now continuing at the spin-out Sunfish, Inc. Dr. Richmond will lead the robotic deployment of the SUNFISH® vehicle during Year 2 of the project, having the vehicle autonomously map and survey any interesting caves or other features to identify high-interest areas to sample some sediments from for further analysis.

Kelly Monteleone

Kelly Monteleone

Co-Principal Investigator; Data Analyst, Mount Royal University’s Registrar's Office; Adjunct Assistant Professor, University of Calgary

Kelly Monteleone is an underwater archaeologist and data analyst at Mount Royal University’s Registrar's Office and an Adjunct Assistant Professor in the Department of Anthropology and Archaeology at the University of Calgary. She completed her Ph.D. in Anthropology in May 2013 from the University of New Mexico and is actively seeking an assistant professorship in Canada. She has a Master’s of Science in Maritime Archaeology from the University of Southampton, United Kingdom, and an Honors Bachelors of Science in Archaeology from the University of Calgary. Her research focuses on locating submerged archaeological sites on the continental shelf of southeast Alaska. The larger research questions revolve around how and when people migrated to North America, whereas local questions involve interdisciplinary collaboration to understand the environment at the end of the Pleistocene and beginning of the Holocene, specifically 17,000 to 10,000 calendar years before present (cal BP). Dr. Monteleone is exploring a Two-Eyed Seeing approach to her research, in which scientific answers are viewed and detailed alongside the local Indigenous Knowledge. In southeast Alaska, she works with the Sealaska Heritage Institute to collaborate and learn from the local Haida, Tlingit, and Tsimshian peoples who have inhabited the region since at least the last glacial maximum.

Jason Gulley

Jason Gulley (Year 2)

Lead Technical Diver and Photojournalist

Jason Gulley is a Tampa-based geology professor, diving instructor, and photojournalist specializing in climate and the environment. Before heading to university in 1998 and accidentally becoming a scientist, Jason spent a year as a photographer, darkroom technician, and reporter for the Harrison Press, a small, weekly broadsheet in rural Ohio. Jason received a Ph.D. in geology from the University of Florida in 2010 and is currently a geology professor at the University of South Florida. When travel restrictions caused by the COVID-19 impacted all of his research projects, he had a lot of time to reflect on his career and had an epiphany of sorts: scientists know more about how humans are impacting the planet than at any other point in history, but fewer non-scientists seem to understand or care about it. Recognizing that more science was not going to help address some of the most urgent issues facing society, he began using his background in journalism to photograph, and occasionally write, news stories that dovetailed with his research. His work has been featured in National Geographic Magazine, GEO France, Wired, The New York Times, The Washington Post, and The Guardian.
