Research Scientist Manager

I support the Business Quality team at Instagram. Our team works on challenging problems in the ads ranking/recommendation systems. We design proper value functions and optimize for users outcomes. We enable delightful commercial experiences for Instagram users in order to sustainably grow advertising on Instagram.

Prior to FB, I started my career in GE global research where I was a site PI leading the area of building imaging diagnostic solutions for breast cancer screening.
