Honored that our work on label-free optical mapping of single 5-nm quantum dots using our photothermal-based FLOWER platform was selected for inclusion in Optics & Photonics News’ Year in Optics 2025 issue.

Each year, the December issue of Optics & Photonics News—the monthly magazine of Optica—highlights the most exciting optics research from around the world in the preceding 12 months.

Labels like fluorescent tags are powerful but often perturb the system. Our work highlights FLOWER, a technique that eliminates this need by using frequency-locked optical microcavities for ultra-sensitive, stable, and portable label-free sensing.

I’m happy to share that our Feature Article is featured on the front cover of Chemical Communications as part of the Pioneering Investigators collection.

 

 

Thrilled to share that our team under the leadership of Pri Narang (UCLA) has been selected as a Stage 1 Winner of the NIH Quantum Sensing Technology Challenge.

This recognition highlights the potential of quantum-enabled technologies to transform biomedical research. We’re looking forward to competing in the second stage.

Grateful to NIH for launching this forward-looking initiative.
