I am a senior hardware engineer at Luca Medical Systems, a medical device start-up company that develops autonomous platforms for clinical radiation therapy systems.
I lead hardware design and optimization tasks by combining mechanical engineering, nuclear radiation physics, and optical systems design principles.
I enjoy tackling translational projects - I am currently working in close collaboration with researchers at Stanford University to bring research prototypes into the market.
This website is an archive of my past research, in which I pursued with passion during my academic years until 2018. They were geared towards challenging the status quo in popular cancer detection and therapy techniques.
