Welcome to the Ganapati Lab

We are a research group in the Swarthmore College Engineering Department. Our focus is creating physics-based machine learning algorithms for computational imaging systems. Examples of computational imaging include computed tomography (CT) and LED array microscopy, where hardware and software are co-designed to enable enhanced capability such as 3D imaging. However, these advanced features come at the cost of long acquisition times. In our group, we create data-driven design methods for computational imaging systems to improve temporal resolution, enabling scientific discovery in previously inaccessible regimes.

Our research is interdisciplinary, drawing from physics, optimization, machine learning, and signal processing. We collaborate with the Swarthmore College Biology Department, co-located with us in Singer Hall, using Fourier ptychography to visualize microscopic phase objects such as planarians, sea urchins, and human cells. We also collaborate with Janelia Research Campus on reconstruction methods for X-ray holographic nano-tomography and Lawrence Berkeley National Laboratory to improve micro-computed tomography.

We are always looking for motivated Swarthmore undergraduates to join our team! (more info)
