Thomas Sears is a Ph.D. candidate in the Department of Electrical and Computer Engineering at Queen’s University, in Kingston, Canada. He is passionate about the exploration of space and connecting people with all things science and technology. Thomas joined the Offroad Robotics research group in September 2019. His research focuses on spatiotemporal environmental modeling during robotic exploration. With the ability to make predictions about the external environment, autonomous vehicles will be able to anticipate, reject, and exploit exogenous disturbances. Thomas is a Vanier Scholar and member of the Ingenuity Labs Research Institute.

Thomas previously studied Aerospace Engineering at the University of Toronto Institute for Aerospace Studies (M.A.Sc.) and Carleton University (B.Eng.). As a member of the Space Flight Laboratory, his research on materials and mechanisms for spacecraft de-orbiting technology was critical to the demonstrated success of the CanX-7 nanosatellite mission. Prior to joining the Offroad Robotics group, Thomas was an Design, Assembly, and Test Engineer at Sinclair Interplanetary (now Rocket Lab) in Toronto, Ontario. In this role, he developed, built, and tested spacecraft attitude determination and control hardware. Thomas has built over 100 devices that are already in or destined for space.

In addition to his research, Thomas works as a consultant in the Canadian space sector, mentors students looking to get involved in the space engineering sector, and volunteers on the advisory board for the Engineers in Residence program. At Queen’s University he supports the CubeSat project with the Queen’s Space Engineering Team and helps facilitate a year-long workshop known as “Space School” for keen students looking to augment their degrees with space systems engineering.

Thomas is a licensed Professional Engineer in the province of Ontario.
