In 2011, I earned my PhD from MIT in the EECS Dept while working in CSAIL as a part of the Marine Robotics Group headed by Professor John Leonard.

About Me


I am truly passionate in seeing physical environments becoming seamlessly enhanced with robotics and autonomous systems. My PhD work involves developing an architecture for an autonomous mobile robot operating in dynamic environments for long periods. The robot is required to operate in large-scale, unknown environments, detect and collect specific data that changes over time, cope with physical changes, and manage large amounts of data. As a result, the robot must construct and maintain a current model of its environment. The model must capture both the physical layout and the specific data in the environment that the robot is tracking. My research focuses on two key challenges. The first is to develop autonomous exploration and mapping algorithms for sustained operation in dynamic environments. The second is to develop a strategy that enables a persistent robot to maintain an up-to-date model of its environment, while coping with physical changes.

In February 2010 I received the MIT MLK Leadership Award and gave my first (and perhaps last)  Impromptu Speech. A couple months prior, I was given an Ambush Makeover by Glamour magazine for dressing like an MIT student while in sunny FL. The Ambush was featured on the Today Show!

We are collectoing computers and related equipment to take over to the Community Technology Center in Laare, Kenya Jan 2007. If you have any equipment or ideas feel free to contact us (see web page).

MIT- Africa Internet Technology Initiative (AITI)

I had the honor to be a part of the MIT-AITI Ghana 2004 team. We taught Computer Programming with Java and Entrpreneurship at the Universtiy of Ghana, Legon.
Life changing experience!

MIT Center For Bits and Atoms (CBA) Fab Labs
I spent a few weeks helping to set up a Fab Lab at the Takoradi Technical Institue in Ghana, West Africa.This project was through the MIT Media Lab Center for Bits and Atoms. Again, another amazing and life changing experience!
