With more than 60 faculty members, 330 graduate students, and 800 undergraduate students, the Department of Mechanical Engineering is innovating today what will impact tomorrow’s solutions to meeting our energy needs, homeland security, biomedical devices, and transportation systems. We offer B.S. degrees in mechanical engineering as well as resident (M.S., Ph.D.) and online (M.S., M.Eng.) graduate degrees in mechanical engineering. See how we’re inspiring change and impacting tomorrow at

The Ken and Mary Alice Lindquist Department of Nuclear Engineering at Penn State is one of the top ranked nuclear engineering programs in the United States. A strong focus on experimental research distinguishes us from many other programs. Our actively growing program has 8 faculty members and almost 90 graduate students. In the Radiation Science and Engineering Center, nuclear engineering students can take advantage of the Breazeale Nuclear Reactor, the longest operating university research reactor in the country.
