Dr. Ruben is interested in control and system theory. His focus is in design, modeling, control, and application of optimization in mechatronic systems. In addition he is exploring using GPUs for fast embedded numerical implementation of optimization solvers, control algorithms, and computer vision algorithms needed to attain solutions in real-time. Dr. Ruben is especially interested in using robotics, art, and music as a mechanism for technology education. Science, technology, engineering, art, and mathematics (STEAM) educational outreach in K-12 education is a passion of Dr. Ruben's.
