We advance quantum science and nanotechnology through innovative optical manipulation, manufacturing and measurement at the nanoscale. We invent new optical tweezers, lithography and spectroscopy to construct atom-precise nanoscale building blocks into architected nanomaterials and to investigate their exotic quantum and classical phenomena. Machine learning is applied for inverse design, automated experimentation and performance prediction of the nanomaterials for targeted applications.

Many of the basic molecular building blocks of life are chiral species, which are non-superimposable on their mirror images. We develop metamaterial-enhanced chiroptical spectroscopy and tweezers to enable label-free enantiodiscrimination and enantioselective separation of chiral molecules. We further integrate the spectroscopy and tweezers into portable tools, which are applied to detect space life, explore the origin of life, probe planet habitability, diagnose diseases, and enhance drug safety.

We develop optical lab-on-a-chip devices and micro/nanoscale robots to bring healthcare diagnostics and therapy to underserved areas while advancing life sciences. Our devices and robots merge functional materials, optics, fluidics and machine learning at the micro/nanoscale to interrogate, manipulate and dissect biological organs, tissues, cells, bacteria, viruses, organelles and molecules at an unprecedented level.
