He was the first to detect cosmic shear, or weak lensing by the large-scale structure of the universe. He was also the first to detect a cluster of galaxies through its gravitational effects alone, and the first to combine source redshift information with lensing to probe structure in three dimensions (tomography).

David Wittman at UC Davis. High-redshift cluster of galaxies discovered through its gravitational effects alone, in the Deep Lens Survey.
I was lead author on the discovery of gravitational lensing by large-scale structure and on the first discovery of a galaxy cluster via lensing and the first use of tomography in lensing, and I continue to pursue these topics through the Deep Lens Survey and the planned Large Synoptic Survey Telescope described below.
I developed a passion for bringing relativity to thinkers who happen to have no physics background. This book includes all the best thinking tools I developed over a decade of teaching this topic as a Topics in Physics course as well as through the University Honors Program. Research Articles.
Jun 1, 2018 · David Wittman, a professor of physics at the University of California, Davis, earned his AB in physics from Harvard University and his PhD in astronomy from the University of Arizona. His research focuses on using gravitational lensing to map dark matter and better understand its behavior.
