The Department of Earth Sciences in the College of Earth, Ocean, and Environment at the University of Delaware invites applications for a 9-month, tenure-track faculty position in Geochemistry at the rank of Assistant Professor, starting in Fall 2026. We seek a motivated scientist who will establish a robust, externally funded research program, teach effectively across the undergraduate and graduate curriculum, mentor graduate students, and contribute to a collaborative and interdisciplinary academic environment. We are particularly interested in candidates with expertise in stable isotope geochemistry, with applications in areas such as environmental geochemistry, critical minerals, carbon sequestration, and other emerging topics in geochemistry.
ROLE AND RESPONSIBILITIES
The successful candidate will have a Ph.D. in Earth Sciences or a closely related field, extensive experience operating mass spectrometers, and the ability to oversee and further develop our existing stable isotope facility. The Department of Earth Sciences at the University of Delaware houses a state-of-the-art stable isotope laboratory equipped with advanced instrumentation capable of measuring isotope ratios and concentrations of hydrogen (H), carbon (C), nitrogen (N), oxygen (O), sulfur (S), and chlorine (Cl). Measurements can be performed on a wide range of materials, including minerals, water, gases, organic compounds, soils, and biomass. The laboratory features multiple Thermo Scientific Delta V Plus IRMS systems, a GC IsoLink II, Trace 1300 GC, EA IsoLink OH and CNS analyzer, Dionex ICS 2100 ion chromatograph, and an LGR Triple Isotope Water Analyzer. A recent addition to the facility is the Thermo Scientific Exploris 240 Orbitrap Mass Spectrometer for high-resolution isotope analysis. The department also maintains a gamma spectrometry system for measuring natural radioactivity.
In addition, the University offers access to the Advanced Materials Characterization Laboratory, a shared core facility equipped with a Thermo Fisher iCAP TQ ICP-MS with laser ablation and chromatography capabilities, and a suite of X-ray diffraction and fluorescence instruments. Electron, confocal, atomic force and other microscopes are housed in the Keck Center for Advanced Microscopy and the Bioimaging Facility. A full list of core facilities and institutes is available at the University’s website.
The successful candidate is expected to integrate the Stable Isotope Laboratory into their research program and leverage its capabilities to support their scientific endeavors. The ideal candidate will build on existing strengths in the Department of Earth Sciences that include geobiology, environmental geochemistry, hydrology, geomorphology, solid Earth geochemistry, and geophysics. The successful candidate will have opportunities to collaborate across the university with faculty in units such as the Department of Geography and Spatial Sciences, the School of Marine Science and Policy, the Department of Civil, Construction, and Environmental Engineering, and the Department of Plant and Soil Sciences. Interdisciplinary efforts may include interactions with the Delaware Environmental Institute, the Gerard Mangone Climate Change Science and Policy Hub, and the Delaware Geological Survey.
Recognized by the Chronicle of Higher Education as one of America's best universities to work for, the University of Delaware is located in Newark, Delaware, a vibrant college town within two hours of New York, Philadelphia, Baltimore, and Washington, D.C. State-assisted, privately governed, UD is a Carnegie R1 Doctoral University and a Land Grant, Sea Grant, and Space Grant institution.

Get Access To All JobsTips for Finding Geochemist Jobs
Target extractive industry employers
Oil companies like ExxonMobil, Chevron, and BP frequently sponsor geochemists for exploration projects. Mining corporations and environmental remediation firms also have established sponsorship programs for geological specialists.
Emphasize specialized geochemical techniques
Highlight expertise in mass spectrometry, X-ray diffraction, or isotope analysis. Specialized laboratory skills and field sampling experience strengthen your case as requiring specialized knowledge unavailable domestically.
Consider environmental consulting pathway
Environmental firms like AECOM, Jacobs, and Tetra Tech sponsor geochemists for contamination assessment projects. Government contracts often require specific technical credentials that international candidates possess.
Location flexibility increases options
Geochemist positions cluster in Texas, California, Colorado, and Alaska. Being open to field assignments and remote locations significantly expands your pool of potential sponsoring employers.
Professional certifications add credibility
Registered Professional Geologist certification or American Institute of Professional Geologists membership shows commitment to U.S. standards. These credentials help differentiate you from other international candidates.

Find Geochemist JobsFrequently Asked Questions
What degree do I need for geochemist visa sponsorship?
A bachelor's degree in geochemistry, geology, chemistry, or earth sciences meets H-1B requirements. Most positions prefer advanced degrees, with petroleum geochemistry and environmental chemistry being particularly valued specializations. Australian and European three-year geology degrees are generally accepted as equivalent to U.S. four-year programs.
Do geochemist roles qualify as specialty occupations?
Yes, geochemist positions consistently qualify as H-1B specialty occupations due to the specialized scientific knowledge required. The role requires understanding of chemical processes in geological systems, laboratory analytical techniques, and specialized software like Geochemist's Workbench or PHREEQC that aren't common knowledge.
How to find Geochemist jobs with visa sponsorship?
To find Geochemist positions with visa sponsorship, use Migrate Mate, which specializes in connecting international professionals with sponsoring employers. Focus your search on mining companies, environmental consulting firms, oil and gas corporations, and research institutions that commonly hire geochemists. These employers frequently offer H-1B, O-1, or other work visas for qualified geological scientists with specialized expertise in geochemistry.
Which industries sponsor geochemists most often?
Oil and gas companies lead in geochemist sponsorship, followed by environmental consulting firms and mining corporations. Petroleum companies need geochemists for reservoir analysis and exploration. Environmental firms sponsor for contamination assessment and remediation projects requiring specialized chemical analysis of soil and groundwater.
Can geochemists qualify for O-1 extraordinary ability visas?
PhD geochemists with significant research contributions, published papers, or specialized expertise in areas like isotope geochemistry may qualify for O-1 visas. Evidence includes peer-reviewed publications, conference presentations, or recognition for developing new analytical techniques. Most entry-level positions stick with H-1B sponsorship.
Are there geographic limitations for geochemist sponsorship?
Geochemist opportunities concentrate in energy and mining regions like Texas, Colorado, California, and Alaska. Many positions involve field work at remote sites. Some employers require willingness to travel internationally for projects, which can complicate visa status but also demonstrates specialized expertise needed globally.
What is the prevailing wage requirement for sponsored Geochemist jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
