Teaching Statement

As a computer science teacher, my goals are to help students develop a strong understanding of the fundamental concepts of computer science, and along with this, an enthusiasm and excitement about the field. I want to help students appreciate the breadth of computer science, and realize the significant impact that they can have on problems from a wide variety of disciplines, from economics through biological sciences to education.  

I am committed to helping students develop problem-solving and critical reasoning skills as well as confidence that they can be active agents of their own learning. I would like them to learn to work effectively in teams, to appreciate the value of interdisciplinary approaches to problem-solving, and to communicate clearly with a variety of audiences, both technical and non-technical. 

I enjoy teaching both core courses in the Computer Science curriculum and elective or advanced courses related to my research interests in robotics, artificial intelligence, and algorithms. I also enjoy working one-on-one with students on their senior theses and other research projects.

Courses taught at Ashesi University:

  •       Programming II
  •       Data Structures and Algorithms
  •       Robotics
  •       Algorithm Design and Analysis

Research Statement

My academic interests are related to the intersection of algorithm design, artificial intelligence, and robotics. Being passionate about education and development, I am also very interested in work that applies these knowledge areas in addressing development challenges.  My PhD dissertation involved developing algorithms for optimal coordination of constrained multi-robot teams.  Other past and current projects, in collaboration with others, include developing path-planning algorithms for robots, studying the potential role of automated tutoring in improving literacy in Ghana, and using machine learning algorithms and mobile devices to determine road surface quality.
