Happy to share my article in Optics & Photonics News: www.optica-opn.org/home/article... Thanks to Optica for the opportunity and to my amazing co-organizers (Prineha Narang and Bruce Hay) and colleagues!

Next week, I'll be attending the Exposome Moonshot Forum (exposomemoonshot.org) in Washington, D.C. as a steering committee member, contributing to the development of the Human Exposome Project.

Glad to share our latest paper on optical biosensors for diagnosing neurodegenerative diseases: www.nature.com/articles/s44... @natureportfolio.nature.com @uazbio5.bsky.social

Getting ready for #CLEO2025 in Long Beach! I’m co-chairing the Biomedical Applications sub-committee, giving an invited talk in Environmental Sensing, and speaking at a panel on Smart Optics + AI/Quantum metrology. Excited to reconnect & catch the latest in photonics!

BIO5 member Judith Su @judithsu.bsky.social builds ultra-sensitive optical sensors to detect disease at the molecular level. At Behind BIO5, she shared how a passion for microscopic worlds led to breakthroughs in early diagnosis and cross-disciplinary innovation. Read more: bio5.org/news/meet-sc...

Enjoyed the gathering and discussions on Chemical and Biological Defense at the 2025 Gordon Research Conference in Ventura, California, during our spring break.

I am very excited about visiting Caltech on Sat. 03/29/2025 to speak at the Materials and Process Simulation Center Conference (www.caltech.edu/campus-life-...) in celebration of Bill Goddard's 88th birthday! Looking forward to connecting with fellow researchers and sharing our latest advances.

Glad that our latest paper has generated interest and has been selected to be featured on Nature Protocol's website. @natureportfolio.bsky.social @uarizona.bsky.social @spie.org @optica.bsky.social
