For his undergraduate education he studied mechanical and aerospace engineering at Princeton University and graduated magna cum laude in 1989.
After college he joined NASA's Jet Propulsion Laboratory in Pasadena, CA where he worked on a comet nucleus sample return mission.
In 2004 Alleyne was the youngest person[citation needed] in the Department of Mechanical Science and Engineering at the University of Illinois Urbana-Champaign to be promoted to Professor.
His work relies on control theory; a means to evaluate how systems behave with a series of inputs and desired outputs.
[4][5] Alleyne has created several high precision algorithms that include design rules for ILC feedforward trajectories.
[7] He has created ways to dynamically monitor and control thermal management systems for power electronics, which are used in planes, ships and cars.
Alleyne worked with the Air Force Research Laboratory to create the Aircraft Transient Thermal Modeling and Optimization toolbox.
His awards and honors include; In addition to serving in numerous service leadership roles at Illinois and in the broader professional academic community, Alleyne has worked to improve inclusivity and gender balance within science and engineering.
