Robert Martin Glaeser (born July 20, 1937) is an American biochemist.
His main research area is electron diffraction and membrane models.
Glaeser is known[1] for his pioneering work in cryogenic electron microscopy (cryo-EM), where he established how radiation damage was a limiting factor for imaging resolution[2] and how freezing hydrated specimens allowed for more tolerance to radiation damage.
[3] He also pushed electron imaging microscopy resolution and contrast by studying the effect of beam-induced movement on the resolution[4] and developed methods for weak-phase imaging.
In 1988/89 he was a visiting scientist at the Max Planck Institute for Biochemistry (MPIB) in Martinsried near Munich, and later a professor at the University of California, Berkeley.
