I utilize the record of ancient sedimentary basins to understand long term changes in climate and tectonics. I utilize geochronology as a tool to determine the provenance and age of sedimentary strata to build a chronostratigraphic framework. This framework can be used to interpret long-term and large-scale tectonic feedback that include mountain building, erosion, sediment transport, and sediment deposition. I apply this method to sedimentary basins located within active convergent margin settings such as southern Alaska and ancient basin deposits of the Devonian Temple Butte Formation in the Grand Canyon.
Active research includes the Cenozoic record of strike-slip basins located along the Denali and Tintina Fault system. Little is known of the younger Cenozoic record of these tectonic scale fault systems and how that record fits into our current understanding of large scale displacement. One way to investigate them further is to look at the record archived within the strike-slip basins formed along them.

My field-based research involves geologic mapping, measurement of detailed bed-by-bed stratigraphic sections, geochronologic sample collection, and paleodirection measurements. I also have experience in working with samples from scientific drilling expeditions such as the Integrated Ocean Drilling Program Expedition 341 that collected samples from the deep marine to continental shelf of the Surveyor Fan system in the Gulf of Alaska.
I have diverse field experience that range from working remotely that includes backcountry work in the Alaskan wilderness of Southern Alaska, working by boat on the Colorado River in the Grand Canyon, and working in Indigenous communities. Field conditions vary and often require long hiking distances to reach study areas in addition to using aircraft such as helicopters and fixed-winged aircraft to reach very remote locations. In each case of field work, field safety of everyone involved is top priority and training (Bear Safety, Gun Safety, Helicopter Safety) are provided depending on each situation.

Indigenous Data Sovereignty and Stewardship in the Geosciences
Indigenous Data Sovereignty and Stewardship in the Geosciences
As a Diné geologist, I am passionate in supporting Indigenous communities to actualize their self determination through Indigenous data sovereignty and stewardship when participating in geoscience research. I am particularly interested in how data repositories implement a data ecosystem that is relevant with FAIR (Findable, Accessible, Interoperable, and Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, and Ethics) Principles in the geosciences.
Additionally, I am interested in the inventory of legacy datasets held by federal agencies and academic institutions that belong to Indigenous communities.
With the Rising Voices Changing Coasts Hub (RVCC), I collaborate with the National Center of Atmospheric Research (NCAR) to produce highly-usable and culturally relevant information for Indigenous coastal communities from Hawaii, Alaska, Louisiana, and Puerto Rico. Implementation of principles such as the CARE and FAIR principles to data repositories in the geosciences is largely unexplored especially in convergence science research settings. There remains an opportunity to construct a data ecosystem for the RVCC that is fit for purpose for Indigenous communities in each region and also to evaluate existing data systems for managing geoscience data that uphold the Indigenous sovereignty for Indigenous communities.
