I am super passionate about artificial intelligence and, more specifically, reinforcement learning. In particular, I am interested in designing agents capable of acting in a wide variety of environments. My current research focuses on autonomously learning hierarchies of abstractions that can be transferred between tasks. This parallels the way humans are able to transfer abstract concepts from one task to another in the form of symbolic representations.

Responsible for delivering Android applications related to the insurance industry, and integrating said applications into the existing backend and proprietary hardware systems.
Part of a small R&D team responsible for rewriting components of an ERP suite, including replacing the existing Telnet connection to the server with SSL, as well as providing a mechanism for session recovery should the connection be lost. Also responsible for rewriting the entire front-end in JavaFX to be used on multiple platforms.
Responsible for setting and conducting tutorials and lab sessions, as well as marking test scripts.
