About

Welcome to my website! I am the CEO and Co-founder of Gamma Reality Inc. (GRI), a company that is working to make nuclear technologies safer and more efficient through 3D data fusion.

Prior to my work at Gamma Reality Inc., I was an Imaging Scientist at Openwater, where I focused on developing medical imaging technologies using near infrared lasers, holograms, ultrasound, and high volume consumer electronics manufacturing. My work involved image reconstruction, which was a challenging and exciting modality to work on.

Before that, I worked as a Research Scientist in the Applied Nuclear Physics group at Lawrence Berkeley National Laboratory, where I specialized in gamma-ray imaging and the development of image reconstruction algorithms and real-time data fusion techniques. This work took me all around the world to perform live field measurements and demonstrations.

I am also a musician, specializing in improvised saxophone and the use of a custom music generation program. I studied both Jazz Studies and Nuclear Engineering at the University of Michigan, and these dual passions have informed and inspired much of my work. Thank you for visiting my website, and I hope you find the information here helpful and interesting.
