Dr. David Needell

Alumni - Academic Postdocs


David Needell received his Ph.D. in Materials Science in the fall of 2021, developing computational techniques and exploring novel application areas for luminescent solar concentrator photovoltaic devices. Becoming infatuated by the thermodynamic limits of light-matter interaction within such devices, David transitioned to more fundamental research questions in photonics — joining Professor Xiaoyang Zhu’s group at Columbia University as a Postdoctoral Fellow investigating photon to magnon (spin-wave) transduction in emerging two-dimensional antiferromagnetic materials. Outside of the lab, David loves backpacking various thru-hikes, banging away at the drums in several rock groups, and doting on his adorably orange cat.
