Euan McLeod started as an assistant professor at the College of Optical Sciences in the University of Arizona in 2015. He was previously a postdoc in Electrical Engineering and Bioengineering at UCLA, as well as a postdoc in Applied Physics at Caltech. He received his Ph.D. from Princeton University, and his B.S. from Caltech. Euan’s background and interests lie at the intersection of optics, nanoscience, and soft bio-materials science. His most recent work has been a mixture of experiments and simulation with the goal of improving the sensitivity of lens-free holographic microscopy for imaging virus-sized and smaller particles.
