Professor Anqi Zhang's group in the Department of Medical Engineering at the California Institute of Technology (Caltech) is recruiting for one postdoctoral position and multiple PhD positions focused on flexible brain-machine interfaces and neuroengineering. The group develops innovative tools for monitoring and modulating neural circuits using electronic, chemical, and genetic engineering approaches, with the goal of translating these technologies from the lab to clinical applications for understanding and treating neurological disorders. The research integrates materials innovation, bioelectronic engineering, and translational neuroscience. PhD applicants should have a background in engineering or science, especially in biomedical engineering, electrical engineering, materials science, mechanical engineering, chemical engineering, neuroscience, chemistry, or physics. A strong experimental background and self-motivation are preferred. Postdoc applicants should have expertise in areas such as mechanical design, microfabrication, surface chemistry, molecular biology, biological sample processing, and/or animal surgery. The PhD application deadline for Fall 2026 is December 15, 2025. Postdoc applications are reviewed on a rolling basis. Interested candidates should contact Prof. Anqi Zhang with a CV and research interests, and follow the application instructions on the Caltech Medical Engineering website. Funding is not explicitly detailed but is typically provided for both PhD and postdoc positions at Caltech.
