Postdoctoral Research Fellow

Dr Samuel Powell


“Followed by itself is this sentence,” followed by itself is this sentence.

Samuel recently finished his PhD in Computer Engineering at Washington University in St. Louis, advised by Prof. Viktor Gruev. His primary focus was on image sensors, polarization, and applications in image processing and machine learning. His dissertation is titled “Underwater Celestial Navigation”.


Samuel is currently pursuing research in applying our knowledge of animal vision systems to sensor design, and image processing applications.
