Bostonian turned CA trail lover. During the day I am a Samsung employee, working with startups in AI and cybersecurity to get their awesome technologies integrated into our products (and hopefully make an investment or two along the way). Outside of work you can find me on trails from Silicon Valley to Tahoe as an ultra-marathon runner specializing in the 100k and 100-mile distances. I serve as the president of the Stevens Creek Striders, the oldest trail running club in the SF Bay Area, and I serve as an Aid Station Captain at the Castle Peak 100K and Quicksilver 100k, while volunteering at many other races through PCTR and BaytrailRunners . If I had a tagline it'd be "ultra-marathoner and strawberry aficionado".
