Honored to be invited to speak at MSC² 2026 at Caltech this weekend, celebrating William A. Goddard III’s 89th birthday.

New in Laser & Photonics Reviews: onlinelibrary.wiley.com/doi/full/10.10… Free-space–coupled, frequency-locked WGM microtoroids for gas sensing. 25 ppt detection (2-CEES) 10⁷ Q preserved after polymer coating 3 orders of magnitude improvement No fiber tapers. Real-world comptabile.

Together with researchers submitting manuscripts to Optics Letters and reviewers, I look forward to advancing impactful work across these areas of optical science and engineering.

Beginning today, I am serving as Topical Editor of Optics Letters, with topical areas in optical resonators, biophotonics, and optical sensing.

Congratulations to the 115 members who are now Optica Fellows! Check out OPN's February issue to meet all 115 of them: bit.ly/3OFInaE

The @uarizona has formalized an agreement with @NYCU_official to establish a Talent and Innovation Hub, preparing students for high-tech, globally connected careers through dual degrees, cultural competency and immersive international experiences. More: tinyurl.com/mve6cc2e

Highlighted in OPN's #OpticsIn2025: An #imaging platform that combines photothermal #microscopy with an ultra-high-Q whispering gallery mode microtoroid resonator to achieve extreme sensitivity and high spatial resolution. bit.ly/45grqZM

OPN's special December issue looks at interesting research from the past year. But what about the year ahead? Several “Optics in 2025” contributors share their thoughts: bit.ly/4jd5Ifn #optics #physics #technology

Many thanks to the students and collaborators who contributed to this effort, and to our sponsors, the National Institute of Mental Health (NIMH) and the National Institute on Aging (NIA), for their support.

Happy to share that our team has been awarded U.S. Patent 12,474,272 for a lipid-bilayer functionalized optical resonator biosensor platform that enables ultrasensitive biomolecule detection.

I am honored to have been elected as a Fellow of Optica. I would like to express my gratitude for the support of my peers, my sponsors, and the diligent efforts of my talented group. optica.org/get_involved/a…

This issue highlights 30 of the most exciting peer-reviewed optics papers from the past year. My thoughts on optics in 2026 and beyond were also included. Many thanks to my team and sponsors (NIH and Gordon and Betty Moore Foundation) for making this possible.

I’m honored that our work on label-free optical mapping of single 5-nm quantum dots made the front cover of Optics & Photonics News’ year-end issue. optica-opn.org/home/articles/…

I'm delighted to be giving another talk at @Caltech on October 23. I look forward to sharing ideas and discussion of mutual research interests. Applied Physics Seminar - caltech.edu

I look forward to meeting more people and exploring mutual research interests through discussions.

I’m excited to give a talk at Caltech’s Chemical Physics Seminar on October 21, 2025, at 2:00 PM in Noyes 153! I’ll be discussing our recent and ongoing developments in label-free, ultra-sensitive optical sensing platforms using microtoroid resonators. cce.caltech.edu/news-and-event…

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. doi.org/10.1038/s41377…

I’m excited to be visiting @Caltech in October! I’ll be giving a seminar on Thursday, October 2 at 4 pm in Gates Annex B122. I look forward to meeting people there and furthering mutual research interests through discussion.
