Benjamin T. Cecchetto, Ph.D.

Research Interests

I'm interested in reconstruction of various phenomena. My Master's research reconstructs a region of origin from sparse blood stain images. This assumes ballistic trajectories for the blood. My Ph.D. research uses visible light and consumer grade electronics to reconstruct heterogeneous scattering materials. This research focuses on implementing cheap and deployable experimental setups. The reconstruction technique has direct applications in medical imaging.

I find using sparse data, an estimated model, and an inverse simulation-based approach quite interesting. If the data (evidence) has known errors, then the simulated model and/or parameters can be optimized.

Keywords: physics, simulation, reconstruction, computer vision, computer graphics, computational photography, image understanding, visual computing
