The University of California, Riverside's Chemical and Environmental Engineering Department is offering a PhD position focused on experimental research in non-exhaust emissions measurement and chemical characterization from mobile sources. The successful candidate will join the Sustainable Mobility and Environmental Laboratory, directed by Professor Georgios Karavalakis, and work primarily at the Center for Environmental Research and Technology (CE-CERT). Research activities include designing and implementing sampling systems for in-use vehicle emissions testing, collecting and analyzing data on brake-wear and tire-wear emissions, and performing chemical analysis using chromatographic techniques and Scanning Electron Microscopy (SEM) with EDX detectors. The candidate will also conduct comprehensive data analysis using statistical models and contribute to scientific publications. Applicants should have a background in Mechanical, Environmental, or Chemical Engineering, with experience in air quality, combustion, laboratory work, and familiarity with real-time particle equipment or chromatographic methods. Solidworks proficiency and a valid US driving license are required. The position offers the opportunity to collaborate with a diverse team of graduate students and research faculty on various projects. Interested candidates should apply by submitting a resume and cover letter via email. Funding details are not specified in the announcement.
