Ron Alexander is a Ph.D. candidate in the Department of Physics at Harvard University's Graduate School of Arts and Sciences working with Prof. Vinothan Manoharan. He is from Baton Rouge, Louisiana, where he also did his undergraduate work majoring in Physics at Southern University and A&M College. At Harvard, Ron is currently designing and building a noninvasive 3D microscope with improved imaging and analysis capabilities through modern statistical inference. He plans to use the 3D holographic microscope in collaboration with other members of the IRG2 to study soft matter and living systems.
