The Cai lab, part of the Health Technology and Engineering Institute (Tech4Health) at NYUGSOM (recently ranked # 4 in medical schools by ‘U.S. News & World Report​’), aims to build new paradigms of nanotechnology for biological and biomedical applications, including optical metasurfaces for bioimaging and biosensing, and nanoengineered biomimetic surfaces for mechanobiology (learn more on detailed research interests). The Tech4Health Institute serves as a hub for the development of new enabling technologies that will advance basic biomedical discovery and clinical care, with close collaboration with biologists and doctors at NYUGSOM, as well as scientists and engineers from worldwide institutions. Immersed in the unique vibrant and innovative environment of the New York City, and one of the foremost medical schools in the world, this is an ideal place for engineering researchers to design technologies to improve human health (learn more). 

Interested individuals should send their curriculum vitae to Dr. Cai’s email Please indicate the position you apply for in the subject, include a detailed descriptions of research interests, and a full list of publications. The positions will remain open until filled.


Position summary

A postdoctoral position to study Optical Metasurfaces and Nanophotonic Biosensors. We build new paradigms of nanotechnology for use in biological and biomedical applications, including optical metasurfaces for bio-imaging and bio-sensing, tunable metasurfaces, and nano-engineered biomimetic surfaces for mechanobiology study.


Candidates must have a PhD in engineering (electrical, mechanical, etc), optics, physics, materials science or other related fields. Those with expertise in optical metasurfaces (near infrared, visible), nanophotonic/plasmonic sensors, nanofabrication (hands-on cleanroom experience), soft materials, biomedical applications, are encouraged to apply.

Those with a strong background in optics and rich experience in optical experiments, finite-difference time domain (FDTD) simulation, high-resolution nanofabrication (e-beam lithography), integration with tunable/responsive soft materials (e.g., liquid crystalline polymer/elastomer, hydrogel) are preferred. Experience that spans multiple fields is a plus.

We seek candidates who are strongly motivated, open-minded, and capable of both independent and collaborative research work. Demonstrated ingenuity, productivity, communication and writing skills, and an excellent record of publications is preferred.


To apply, send your CV to Dr. Haogang Cai, at Please include a detailed description of your research interests, a full list of publications, and names of at least two references.

Graduate student

Prospective and current graduate students in related programs at NYU, NYUGSOM, Tandon School of Engineering, are all welcome to join the research group. Interested students are encouraged to contact Dr. Cai, and explore the opportunity of advising or co-advising.

Visiting scholar/student

Visiting scholars and outstanding visiting Ph.D. students in related fields are also welcome to apply!
