The Department of Chemical and Biochemical Engineering at the University of Iowa invites applications for a Postdoctoral Research Scholar in the research group of Dr. Zhe (Andy) Wang.
The position supports a newly funded, multi-year research program focused on developing an energy-efficient system for producing nitric acid directly from air, water, and electricity. Direct nitrogen oxidation faces a long-standing trade-off between reaction rate and energy efficiency. The program addresses this challenge by integrating non-equilibrium plasma, plasmonic catalysis, thermal conversion, and electrochemical processes for nitric acid formation and concentration.
The Postdoctoral Research Scholar will contribute to experimental research involving plasma reactor operation and diagnostics, plasma–catalyst integration, reactor performance evaluation, and prototype development. The successful candidate will work as part of a collaborative, interdisciplinary research team and will have opportunities to contribute to both fundamental studies and the development of integrated reactor systems.
The initial appointment is scheduled to end on August 18, 2027, with the possibility of annual renewal based on satisfactory performance and the availability of continued funding, for an anticipated total duration of up to three years. Salary and benefits will follow University of Iowa postdoctoral policies.
Responsibilities
- Commission, operate, and troubleshoot plasma reactor systems.
- Characterize plasma conditions using optical and electrical diagnostics and relate plasma properties to reaction performance.
- Integrate plasma sources with catalyst beds and evaluate plasma–catalyst reactor performance.
- Contribute to reactor design reviews, prototype troubleshooting, and the fabrication and integration of scaled-up modules.
- Maintain careful experimental documentation and contribute to technical reports, presentations, and peer-reviewed publications.
- Mentor graduate and undergraduate researchers and contribute to a collaborative and safety-conscious laboratory environment.
REQUIRED EDUCATION
Ph.D. in Chemical Engineering, Chemistry, Materials Science and Engineering, Mechanical Engineering, Electrical Engineering, Physics, or a closely related field, completed prior to the start date.
REQUIRED QUALIFICATIONS
- Substantial hands-on experimental experience designing, assembling, operating, or troubleshooting laboratory-scale reactor, plasma, or related experimental systems.
- Experience working with relevant experimental hardware, such as vacuum systems, gas-handling systems, high-voltage equipment, plasma sources, or electrochemical systems.
- Experience with quantitative measurement and analysis of chemical reaction or reactor performance using at least one relevant method, such as optical spectroscopy, plasma diagnostics, gas analysis, gas chromatography, or mass spectrometry.
- Demonstrated research productivity and effective written and oral communication skills.
- Ability to work independently while contributing effectively to a collaborative research team.
DESIRABLE QUALIFICATIONS
Experience or demonstrated expertise in one or more of the following areas is desirable; candidates are not expected to have experience in all areas:
- Nonthermal plasma systems, including microwave, radio-frequency (RF), dielectric barrier discharge (DBD), or nanosecond-pulsed plasma systems.
- Plasma diagnostics, including optical emission spectroscopy (OES), electrical diagnostics, or Langmuir probes.
- Plasma-assisted catalysis, nitrogen oxidation, NOx chemistry, or related nitrogen-conversion processes.
- Reactor, transport, or plasma modeling using COMSOL Multiphysics, computational fluid dynamics (CFD), kinetic modeling, or related approaches.
- Materials characterization using techniques such as SEM/TEM, XPS, XRD, UV-Vis spectroscopy, or Raman spectroscopy.
- Prototype development, reactor scale-up, or integration of multiple experimental subsystems.
- Collaboration on interdisciplinary projects involving academic, industrial, or national-laboratory partners.
- Prior experience mentoring undergraduate or graduate researchers.

Get Access To All JobsTips for Finding H-1B Visa Sponsorship as a Postdoctoral Research Associate
Verify your degree field matches your research area
USCIS evaluates whether your degree is directly related to the postdoc role, not just broadly scientific. A chemistry PhD supports a synthetic biology postdoc; a general biology degree supporting a computational genomics role may trigger a Request for Evidence.
Target cap-exempt institutions for faster hiring
Universities, affiliated research hospitals, and nonprofit research organizations are cap-exempt H-1B employers. They can file year-round without waiting for the April lottery, so your start date doesn't depend on a single annual selection window.
Search verified H-1B sponsoring labs on Migrate Mate
Filter Migrate Mate by job title and institution type to find postdoc openings at employers with confirmed H-1B LCA filing history. This surfaces labs that have actively sponsored international researchers, not just those that say they're open to it.
Request your offer letter before the LCA is filed
The Labor Condition Application requires a specific wage, start date, and work location. Ask your PI or HR contact for a conditional offer letter with those details locked in before DOL certification begins, since LCA amendments add weeks to the timeline.
Confirm the institution uses E-Verify before accepting
If you're transitioning from OPT or STEM OPT, your new employer must be enrolled in E-Verify to authorize your work through the cap-gap period. Public universities are usually enrolled; smaller private research institutes sometimes are not.
Check prevailing wage for your SOC code and location
Postdoc salaries vary widely by field and institution, but USCIS will reject an H-1B if the offered wage falls below the DOL prevailing wage. Use the OFLC Wage Search to verify the Level I or II wage for your specific occupation code and metro area before your contract is finalized.
H-1B Visa Postdoctoral Research Associate: Frequently Asked Questions
Do Postdoctoral Research Associate roles qualify as H-1B specialty occupations?
Yes. Postdoctoral Research Associate positions qualify because they require at least a bachelor's degree, and typically a PhD, in a specific scientific or technical field directly related to the research. USCIS evaluates specialty occupation on a role-by-role basis, so your employer's job description should explicitly state the degree requirement and field to avoid a Request for Evidence.
Are universities and research institutions subject to the H-1B cap?
Most are not. Universities, affiliated nonprofits, and government research organizations are cap-exempt, meaning they can file H-1B petitions at any time of year without entering the annual lottery. This makes postdoc positions at these institutions particularly accessible for international researchers, since hiring doesn't depend on a single April registration window.
How do I find Postdoctoral Research Associate jobs at employers who actively sponsor H-1B visas?
Migrate Mate lets you filter postdoc listings by employers with verified H-1B LCA filing history, so you can focus on institutions that have sponsored international researchers before rather than those that are uncertain or unwilling. This is more reliable than asking in application cover letters or waiting until late in the interview process.
What documents do I need to prepare before my employer files the H-1B petition?
You'll need official transcripts and degree certificates, a credential evaluation if your degree is from outside the U.S., your current visa documents and I-94 record, and a detailed CV listing your research experience. Your employer's HR or immigration attorney will also need a copy of your offer letter and your passport biographical page to complete Form I-129.
Can I start a postdoc before my H-1B is approved if I'm on OPT?
Yes, if your OPT authorization is still valid when you begin work. If your OPT end date falls before October 1 and your employer files an H-1B petition before OPT expires, the cap-gap rule automatically extends your work authorization through September 30. Your employer must be enrolled in E-Verify to rely on cap-gap, so confirm that enrollment before signing your contract.
