OPEN POSITION: Assistant Project Scientist
Department of Environmental Toxicology – UC Davis
Next review date: Saturday, Jul 23, 2022 at 11:59pm (Pacific Time) – Stays open until position is filled

Final date: Saturday, Jul 8, 2023 at 11:59pm (Pacific Time)
Applications will continue to be accepted until this date, but those received after the review date will only be considered if the position has not yet been filled.


The Nguyen Laboratory through the Department of Environmental Toxicology at the University of California Davis, is currently seeking a Project Scientist, 50-100% time for duration of one year with the possibility of extension dependent upon funding.

The Project Scientist makes significant and creative contributions to a research or creative project in his/her academic discipline. The appointee possesses the subject matter expertise and the creative energy necessary to function at a high level of competence. The appointee will participate in activities to increase, improve, or upgrade competency. Appointees with Project (e.g., Scientist) titles may engage in University and public service. They do not have teaching responsibilities. Although the Project Scientist is expected to work independently under the general guidance of an academic member with an independent research program (i.e., Professor, Professional Researcher, Specialist in Cooperative Extension, etc.), he/she is not required to develop an independent research program or reputation. He/she will carry out research or creative programs with supervision by an individual in an academic title that carries with it automatic Principal Investigator status. The Project Scientist does not usually serve as a Principal Investigator but may do so by exception.


• A PhD Degree in Chemistry, Atmospheric Science, or appropriate related field by start date.

ADDITIONAL QUALIFICATIONS (met by the start date of the position):
• Experience in laboratory research projects involving atmospheric chemistry, aqueous photochemistry, aerosol chemistry, surface chemistry, physical chemistry, analytical chemistry, or related topics.
• Experience in writing research publications (peer-reviewed)
• Aptitude in communicating and extending technical information.
• Interpersonal skills to interact with diverse groups of individuals to facilitate collaborative research, provide information, resolve problems, and increase cooperation among individuals.
• Demonstrated ability to effectively communicate via writing and orally.

• Experience with atmospheric chamber research.
• Experience with gas and aerosol instrumentation, and/or mass spectrometry (high-resolution electrospray mass spectrometry or chemical ionization mass spectrometry).
• Expertise in scripting programs such as Matlab.
• Evidence of collaborative, interpersonal- and communication- skills.

Salary dependent upon candidate’s qualifications/experience.

To apply:


Undergraduate Student Assistant

Undergraduate students (sophomore or junior) who have an A- or better grade in chemistry classes or chemical engineering classes are encouraged to contact Prof. Nguyen for a research internship and/or an Honor’s Thesis project. The undergrads in our lab are valued members. Our undergrads are given opportunities to conduct their own research projects and/or play important roles helping senior members. Our undergrad alumni have been very successful with publishing peer-reviewed papers (as first authors and co-authors), presenting their results at conferences, winning research awards (from UCD and the ACS) and moving on to graduate school, professional schools, or permanent jobs in industry.

We have undergraduate research opportunities in: (1) chemistry in the air, cloud/fog droplets, aerosol particles, (2) chemistry and toxicology of electronic cigarettes, (3) instrumental analysis using gas and liquid chromatography with mass spectrometry, or (4) atmospheric chamber research (chemistry + engineering).
