The CS STAIRSTEP team members include Hannah Leleux, Timothy Gonzales, Colin Smith and Diego Fernandez. We are always looking to include more students. Please download a STAIRSTEP application and send it to Dr. Wang (or campus mail #10056) to apply.


Research - RobotComputer Science STAIRSTEP students perform research in teams under the direction of Professor Doerschuk. Research areas include robotics, AI, and machine learning.

The long-term goal of the robotics research is to develop teams of autonomous robots that can communicate and cooperate to perform their tasks. The Khepera robot is used as the platform for the robotics research.

Current research in AI focuses on developing more efficient learning algorithms. Current research on Computer Science education centers on developing instructional materials for teaching middle school and high school kids computing concepts using fun applications like robotics, web design, and computer animation.


CS STAIRSTEP outreach activities are designed to expose students to the many way in which computing benefits our society and the incredible range of career opportunities in computing. Team members are involved in outreach at LU's Open House, New Student Orientations,  and Career Days at local high schools.
