Cody Ritt

The Nanofluidic Separations Lab at the University of Colorado Boulder, led by Assistant Professor Cody Ritt, is seeking a postdoctoral researcher to develop novel nanofluidic platforms for advancing the design of selective membrane materials. The research aims to translate molecular-scale insights into practical solutions for resource recovery and sustainability. The position is situated within the Department of Chemical and Biological Engineering and leverages the state-of-the-art ISO 5 cleanroom facilities at COSINC, supporting advanced micro/nanofabrication and interdisciplinary research. Key research areas include nanofluidics, membrane materials, resource recovery, and sustainability, with a focus on the behavior of fluids and electrolytes confined below 10 nm. The successful candidate will work on developing nanofluidic devices and model membrane systems to probe transport phenomena across scales, bridging knowledge gaps between molecular interactions and material design for separations. The lab values collaboration, curiosity, motivation, independence, creativity, and academic integrity. Applicants should hold a PhD in Chemical Engineering, Materials Science, Electrical Engineering, Applied Physics, Mechanical Engineering, or related fields. Preferred qualifications include experience in micro/nanofabrication, micro/nanofluidics, and fabrication of 2D heterostructures. The postdoc will mentor students, collaborate with interdisciplinary teams, and contribute to high-impact publications. The position offers a competitive salary, commensurate with experience, and exceptional working conditions, including access to the new COSINC cleanroom and updated lab space. Boulder provides a vibrant lifestyle with access to outdoor activities and travel amenities. Applications are reviewed on a rolling basis until filled, with a deadline of January 26, 2026. To apply, candidates should email a cover letter, CV, and contact information for three references to [email protected] with the subject line: NanoSep Lab PDA Application.
