Dr. Lennon is a principal staff scientist at the Johns Hopkins University Applied Physics Laboratory who applies his expertise in the micromechanics of material deformation to characterization, selection, failure analysis, and design of engineering materials. His current projects include developing additively manufactured shape-memory alloys for use as small, lightweight, and low-power high-force actuators and shape-morphing structures. His primary area of expertise is deformation mechanics of metals, and has also done a considerable amount of work with polymers, ceramics, composites and some biological materials. Dr. Lennon has been teaching in the JHU EP Program since 2009, online since 2015, and previously taught one semester of undergraduate Machine Design in the Mechanical Engineering Department of JHU.
