Hello, I am Aaron.
Optical System Architect

I am a System Architect at KLA in San Jose, CA, where I lead the development of the imaging path for the flagship Broadband Plasma tool, the centerpiece of KLA's product portfolio.

I have dedicated my career to advancing impactful scientific and engineering breakthroughs through optical technologies. My commitment to innovation has resulted in a patent, over 20 publications, and recognition as a Hong Kong Scholar and Hong Kong IT Scholar.

Who am I?

I am someone who thrives on curiosity, adaptability, and a genuine love for learning.

With a PhD in Biomedical Engineering and Applied Physics from Cornell University, I focused on advancing optical imaging technologies. I have always been driven by a passion for creating innovative solutions to impact and benefit many people, which has guided much of my academic and professional journey.

I also enjoy playing the piano and oboe, going to the gym, and diving into a good book.

Experience

With over 10 years of experience specializing in the design and optimization of optical systems, I bring a blend of academic and industry expertise. Currently, I work at KLA as an Optical System Architect. My Ph.D. was mentored by Dr. Chris Xu, the Director of Applied and Engineering Physics at Cornell University and a pioneer in multi-photon microscopy. My Master thesis was guided by Dr. Kevin Tsia, Director of Biomedical Engineering at The University of Hong Kong and a renowned leader in ultrafast imaging.

This enabled me to make contributions in optics, including wafer optical inspection, scattering biological tissue imaging, ultrafast single-cell imaging, and spectroscopic analysis. My work spans from deep UV (~190 nm) to NIR (~2,000 nm).

Interview with Optica

I’m excited to share my interview with Optica at CLEO! It was a great opportunity to present in the post-deadline section and discuss my work.

Interview

A large field-of-view, single-cell-resolution two- and three-photon microscope for deep and wide imaging

It is featured in MIT Technology Review. The Review

We have improved the fluorescence signal generation efficiency of three-photon microscopy, achieving an imaging field two order of magnitudes larger than traditional three-photon microscopes in deep brain regions with cellular resolution.

Paper

Multiphoton imaging of neural structure and activity in Drosophila through the intact cuticle

“This study reports a way to record neural structures and activity in behaving Drosophila for up to 12 hours, without removing the cuticle. This opens the way to longer and more intact recordings, including post-imaging recovery of the flies.” eLife editor

Paper

Spatially resolved measurements of ballistic and total transmission in microscale tissue samples from 450 nm to 1624 nm

We built a simple and versatile spectrometer to measure tissue ballistic and total transmission with customizable wavelength range, spatial resolution, and sample sizes.
