I graduated, my new website is at: sanjayk.ioSaved below for posterity.
I'm a Computer Science PhD student in the RISELab and AUTOLAB at UC Berkeley researching exciting projects that span from databases to robotics. Basically, I like to think about how to build intelligent learning systems, what are the right theoretical tools to understand these systems, and what are the right design principles to scale these systems to the problems of the future. My CV is linked here.
I've done work throughout the whole analytics stack:
How do we collect data? Sensors, Actuators, Crowds
How do we build systems that continuously learn from real-world interactions? Real-world reinforcement, imitation learning, and control
