Experience

ExxonMobil Exploration Company, Houston, TX 2016 - Present
Geoscience Associate
Exploration Strategy - Created a geological and commercial decision tree, enabling rapid incorporation of well results into future drilling decisions, and guiding acreage relinquishment decisions for a lease held in Guyana-Suriname basin.

Acreage Capture - Used regional and basin scale petroleum systems analysis (basin modeling, tectonostratigraphy, and play element mapping) to evaluate and recommend pursuit opportunities, resulting in 2 new acreage acquisitions in West Africa.

Hydrocarbon Assessment - Applied hydrocarbon generation and thermodynamic fluid phase modeling concepts to assess hydrocarbon accumulation size and value at field to basin scale for the Niger Delta.

ExxonMobil Upstream Research Company Houston, TX 2013 - 2016
Research Geochemist
Petroleum Chemistry - Integrated geochemical data (including molecular biomarkers, stable isotope composition, fluid inclusion volatiles, source rock analysis, and physical properties) to evaluate reservoir connectivity, fluid migration, and maturity.

Marine Survey Planning - Coordinated between ExxonMobil personnel, contractors, and academic research collaborators, resulting in safe completion of 3 bathymetric mapping and seafloor sampling campaigns.
Research and Development - Worked with an interdisciplinary team to apply isotopic, molecular biology, and water column imaging techniques to seafloor hydrocarbon seeps, leading to adoption of technologies within ExxonMobil and a patent grant.

ExxonMobil Exploration Business Development Houston, TX 2010 - 2012
Exploration Geologist
Global Source Rock Data Management - Initiated and designed a geospatial database of over 250k proprietary and publicly available source rock analyses that are now available to all ExxonMobil geoscientists.

Source Rock Distribution - Supported regional teams by providing consistent, rapid screening of source rock presence and adequacy using regional geological understanding and stratigraphic principles governing organic enrichment.

ExxonMobil U.S. Production Limited Houston, TX 2010 - 2012
Senior Petroleum Geologist
Field Management - Identified bypassed hydrocarbons in Galveston 209 field on the Gulf of Mexico shelf using seismic mapping and geophysical attribute analysis, resulting in extension of field life.

Carnegie Institution for Science/Woods Hole Oceanographic Institution 2007 - 2010
Post-Doctoral Fellow, joint appointment
Research Design - Proposed and completed an investigation of hydrogen partitioning and transport within basalt magmatic systems using laboratory experiments (piston cylinder, cold seal hydrothermal bombs) characterized using secondary ionization mass spectrometry (SIMS and nanoSIMS), infrared and Raman spectroscopy, and electron microbeam imaging.
