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 H-1B Visa Sponsorship in Geochemist
Verify your degree maps to SOC 19-2042
USCIS evaluates specialty occupation eligibility against the job's SOC code. Pull the O*NET profile for Geoscientists (19-2042) and confirm your degree field appears in the listed education requirements before applying.
Target energy and mining sector employers
Oil and gas producers, mining companies, and environmental remediation firms file LCAs for Geochemist roles far more consistently than generalist engineering consultancies. Search DOL's LCA disclosure data to identify which employers have active filings in your target region.
Search verified H-1B sponsors on Migrate Mate
Filter by occupation on Migrate Mate to see which employers have filed H-1B petitions for geoscience roles. This surfaces active sponsors you won't find through standard job postings alone.
Check prevailing wage before negotiating salary
Your employer's LCA must certify a wage at or above the DOL prevailing wage for your role, location, and experience level. Run the OFLC Wage Search for SOC 19-2042 in your target metro before entering any compensation discussion.
Get your foreign credentials evaluated early
A three-year geology or geochemistry degree from outside the U.S. may require a credential evaluation to establish equivalency to a U.S. bachelor's degree. USCIS scrutinizes this for specialty occupation petitions, so obtain a NACES-member evaluation before your employer files.

Find Geochemist JobsGeochemist H-1B Visa: Frequently Asked Questions
Does a Geochemist role qualify as an H-1B specialty occupation?
Yes. Geochemist positions qualify as H-1B specialty occupations because the role normally requires at least a bachelor's degree in geochemistry, chemistry, geology, or a directly related field. USCIS uses the DOL's occupational classification and the O*NET profile for Geoscientists to confirm the degree requirement. Roles in environmental consulting, mining, and petroleum geology consistently meet the standard.
Which industries sponsor H-1B visas for Geochemist positions?
Oil and gas extraction companies, hard-rock mining firms, environmental remediation consultancies, and federal contractors in the earth sciences are the most active H-1B sponsors for geochemistry work. Government agencies and national laboratories can also sponsor, though some positions require permanent residency. Use Migrate Mate to browse current openings at employers with verified H-1B filing history in this occupation.
How does the DOL prevailing wage apply to H-1B Geochemist roles?
Your sponsoring employer must file a Labor Condition Application certifying that your offered wage meets or exceeds the DOL prevailing wage for your SOC code, job title, and work location. Wages are tiered by experience level from Level I through Level IV. Run the OFLC Wage Search for SOC code 19-2042 in your target city before finalizing any offer to confirm the floor your employer must meet.
Can fieldwork locations affect my H-1B petition as a Geochemist?
Yes. H-1B status is tied to the worksite location listed on the LCA. If your geochemistry role involves extended fieldwork at sites not covered by your employer's original LCA, your employer may need to file an amended petition or a new LCA covering those locations. Short-term assignments under 30 consecutive days at non-LCA sites may qualify for a short-worksite exemption under USCIS rules.
Does a three-year foreign geology degree qualify for an H-1B Geochemist petition?
It can, but it requires a credential evaluation. USCIS requires proof that a foreign degree is equivalent to a U.S. bachelor's degree for specialty occupation purposes. A three-year degree from countries like Australia, the UK, or India is often found equivalent when combined with relevant graduate coursework or professional experience. A NACES-member evaluator's report submitted with the I-129 petition is the standard way to establish this equivalency.
