Dr. Katherine Louise Bouman (born 1989/90) is an American imaging scientist and, starting from June 2019, an Assistant Professor of Computing and Mathematical Sciences at the California Institute of Technology.[1] She researches computational methods for imaging.[2][3][4] She was part of the team who worked on the EHT project of capturing the first image of a black hole.[3]

Early life and education

Bouman grew up in West Lafayette, Indiana, and graduated from West Lafayette Junior-Senior High School in 2007. Her father, Charles Bouman, is a professor of electrical and computer engineering and biomedical engineering at Purdue University.[5] As a high school student, she conducted imaging research at Purdue University.[5] She first learned about the Event Horizon Telescope in school in 2007.[6]

Bouman studied electrical engineering at the University of Michigan and graduated summa cum laude in 2011.[7] She earned a master's degree in electrical engineering and computer science at Massachusetts Institute of Technology, where she also completed her doctorate. Bouman was a member of the Haystack Observatory.[8] She was supported by a National Science Foundation Graduate Fellowship. Her master's thesis, Estimating Material Properties of Fabric through the Observation of Motion,[9] was awarded the Ernst Guillemin Award for best Master's Thesis.[10] Bouman joined Harvard University as a postdoctoral fellow on the Event Horizon Telescope Imaging team.[11][12][13] In 2016, Bouman delivered a TEDx talk, How to Take a Picture of a Black Hole, which explained the algorithms that would eventually be used to capture the first image of a black hole.[14][15] She earned her doctorate in electrical engineering and computer science from MIT in 2017.[16] Her Ph.D. thesis on Extreme imaging via physical model inversion: seeing around corners and imaging black holes was supervised by William T. Freeman.[17]

Research and career

Bouman developed an algorithm known as Continuous High-resolution Image Reconstruction using Patch priors, or CHIRP.[18][15] This algorithm was one of several used to verify the image of the supermassive black hole inside the core of the galaxy Messier 87.[19][20] An algorithm that was used was the CLEAN algorithm[21] which was introduced by Jan Högbom and Andrew Chael.[22]

Bouman was responsible at MIT for an algorithm used in creating the first images of a black hole, published in April 2019,[23] providing computational support to learn about general relativity in the strong-field regime.[8][24][25] The machine learning algorithm fills in gaps in data produced by telescopes from around the world.[2][26] Bouman led efforts in "the verification of images and selection of imaging parameters" for the Event Horizon Telescope.[23]

Bouman will join the California Institute of Technology (Caltech) as an assistant professor in June 2019. She will work on new systems for computational imaging using computer vision and machine learning.[27][24][28]
