In 2006, I joined Oregon State University (OSU) in Corvallis, OR as a postdoctoral scholar.
While at OSU, I was a leading developer of the Modular Electromagnetic Inversion Software (ModEM), and supported a growing user base for this code. I contributed to the NSF's EarthScope USArray MT program through quality control, processing and archiving of the data in the years 2006-2015. I also contributed to multiple NSF projects focused in magnetotellurics, global electromagnetics, and development of metadata standards and cyberinfrastructure. I became an Assistant Professor (Senior Researcher) at OSU in July 2014, and joined the USGS Geomagnetism Program in Golden, CO in May 2015.
Composition of the Earth's crust and mantle as inferred from electrical conductivity of the solid Earth; magnetotelluric and other electromagnetic data interpretation and inversion at regional to global scales; water content and processes in global subduction settings; tectonics and magmatism of the North America; joint interpretation of electromagnetic, seismic and geodynamic models of the Earth's interior.
Effects of space weather on electric power grids and pipelines; geomagnetic storms; geomagnetically induced currents (GIC); volcano imaging using electromagnetics.
Physics-based numerical modeling and high performance computing; scientific workflows; semantics and controlled vocabularies for science; databases and frameworks for long-term sharing and storage of numerical models and data.
In the past 5 years, I developed a suite of data sharing tools for magnetotellurics, including a modern XML-based file format for transfer functions, open source tools for data format conversions and the first publicly accessible, searchable database (SPUD EMTF), as well as a strategy for credit attribution with citable Data Object Identifiers (DOIs). Through these efforts, I am hoping to develop the culture of data sharing in the worldwide magnetotelluric community, and thereby enable next generation of scientific analysis. I continue to contribute, solicit external data contributions and provide support for data uploads and generation of citable DOIs for such data sets. If you have historic or recently collected magnetotelluric data in any format, and are willing and able to share your data set with the worldwide scientific community, I'd love to hear from you!
In my current role as a Research Geophysicist at the USGS Geomagnetism Program, I provide technical support to the NOAA's Space Weather Prediction Center (SWPC) Geoelectric Field Maps data product that is currently in development. I provide scientific
