I am a Research Scientist at Facebook Reality Labs (formerly Oculus Research) in Redmond. I am currently exploring contextual and adaptive approaches for interactions with future augmented reality (AR) devices. I obtained my PhD in Fall 2018 at the Robotics Institute, Carnegie Mellon University working with Stelian Coros and Jim McCann. My research interests lie in applying optimization and data-driven techniques to solve complex real-world problems.
During my PhD, I build computational design tools that enable casual users to build robots, towards increasing accessibility of robotics. In the past, I have also had not-so-brief stints in the area of human motor control and biomechanical simulations. During my Masters, I worked with Hartmut Geyer on understanding human control of leg placement. I have also spent some time trying to understand human balance, and motor skill aquisition in people learning bongoboarding with Jessica K. Hodgins as an intern at Disney Research Pittsburgh. In 2017, I spent a wonderful summer with the User Interface Research group at Autodesk Research, Toronto. I worked with Fraser Anderson, Justin Matejka, and Tovi Grossman on a data-driven design tool for robots.
My PhD research aimed at making robotics more accessible to casual users by reducing the domain knowledge required in designing and building robots. Towards this end, I developed several interactive design tools that enable the design of desired structure and behavior of diverse robots.
Interactive tool for articulated robot design
This tool allows novices to create custom articulated robots such as manipulators and walking robots. It supports both manual and automatic design, and enables design testing using physics-based simulation.
This tool enables novices to create smart IoT devices with embedded sensors using digital fabrication. It automatically finds assembly-aware packing of components within the device, and exports necessary geometries for 3D printing.
Semantic design of expressive robot behaviors
Can we design complex robot behaviors such as robot walking based on the emotion that the behavior evokes?
