Available Positions

Join the team!

Multiple opennings available!

The Cai lab, part of the Health Technology and Engineering Institute (Tech4Health) at NYUGSOM (recently ranked # 2 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, a mission never more relevant than today (learn more). 

These positions will receive competitive stipend and benefits such as health insurance and university housing. They will remain open until filled. 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.


Position 1

A postdoctoral position to study mechanobiology, biophysics and nano-bio interfaces. We build new paradigms of nanotechnology for biomedical applications, including nano-engineered cell interfaces for mechanobiology study and biosensing. Our recent publications in this field include: Nature Materials, 2019, 18, 1366. Nature Nanotechnology, 2018, 13, 610. Candidates must have a PhD in engineering, physics, biology, chemistry, materials science or other related fields. Those with a background in mechanobiology, biophysics, nano-bio interfaces, biosensing, and expertise in selective surface biofunctionalization (using self-assembled monolayer, biolinkers/ligands, DNA linkers/probes, DNA origami, supported lipid bilayer, etc), soft materials (elastomer, hydrogel, supported lipid bilayer, etc), cell assays, fluorescence microscopy, atomic force microscopy, nanofabrication (soft lithography, block copolymer micelle nanolithography, etc) are encouraged to apply. Experience that spans multiple fields is a plus.

Position 2

A postdoctoral position to study Optical Metasurfaces, Nanophotonic sensors. We build new paradigms of nanotechnology for biomedical applications, including optical metasurfaces for imaging/sensing, and active tunable metasurfaces. Our recent publications in this field include: ACS Photonics, 2021, 8, 2581. Advanced Materials, 2021, 33, 2005275. npj Computational Materials, 2020, 6, 116. Candidates must have a PhD in engineering (electrical, mechanical, etc), optics, physics, materials science or an appropriate field. Those with expertise in optical metasurfaces, plasmonics, Si nanophotonics, micro-optics, nanofabrication, are encouraged to apply.

Those with a strong background in optics and rich experience in optical system design and experiments, finite-difference time domain (FDTD) simulation, hands-on cleanroom experience (e.g., e-beam lithography, RIE, evaporation, etc) 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 three references.

Research associate

The research associate position is open to candidates with a Bachelor’s degree in above-mentioned fields. Research experience on optical microscope, table-top optical experiments, experience in chemical/bio wet lab or clean room, simulation and coding skills, experience in data analysis and scientific paper writing, are preferred.

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. We can recruit students in the NYUGSOM Biomedical Imaging & Technology PhD Training Program, graduate and PhD programs of Biomedical Engineering and other engineering departments at Tandon. Interested students are encouraged to contact Dr. Cai, and explore the opportunity of advising or co-advising.
