John Marius Rodenburg FRS is emeritus professor in the Department of Electronic and Electrical Engineering at the University of Sheffield.
[3][4] He was elected a Fellow of the Royal Society (FRS) in 2019 for "internationally recognised... work on revolutionising the imaging capability of light, X-ray and electron transmission microscopes".
He moved to the Cavendish Laboratory[6] to complete his PhD on the detection and interpretation of electron diffraction patterns which was awarded by the University of Cambridge in 1986.
[9] His research interests have mostly been in improving the resolution and other capabilities of electron, X-ray and optical microscopy by processing diffraction patterns instead of using lenses.
[10][11][12][13][14][15][16] In 2006, Rodenburg co-founded Phase Focus Limited, which uses ptychography to image live cells to improve cancer drug design.
