Dr. Johlin is an Assistant Professor in the Mechanical and Materials Engineering department at Western University. He received his Bachelors of Science in Mechanical Engineering from the California Institute of Technology in Pasadena in 2009, performing research on the characterisation of electron energy distributions in ion thrusters at the NASA Jet Propulsion Laboratory (JPL) during his time at Caltech. He went on to do his Masters of Science and Doctoral degrees co-advised in the Mechanical Engineering and Materials Science departments at the Massachusetts Institute of Technology in Cambridge, finishing in 2014, with his thesis entitled "Understanding and Improving Hole Transport in Hydrogenated Amorphous Silicon." His post-doctoral work was performed at AMOLF's Center for Nanophotonics in Amsterdam for three years following his PhD, where he worked on fabrication, characterisation, and modelling of nanostructured photovoltaics. He joined Western University as faculty in March of 2018. Dr. Johlin’s research mainly involves creating new devices with a particular focus on clean energy and photovoltaics. He leads the Nanophotonic Energy Materials group, which explores new structures, materials, and systems utilizing nanophotonics for photovoltaics and other optoelectronic devices.
