Daniel Studer is a graduate of ETH-Z (Federal Institute of Technology Zurich, Switzerland) and was collaborator at the central Electron Microscopy facility of ETH from 1982 to 1992. He then became group leader at the Maurice E. Müller Institute of Biomechanics at the University of Bern, where he investigated the ultrastructure of cartilage (1992–2001). Daniel Studer then moved to the Institute of Anatomy at the University of Bern (2001- present) where he worked on characterizing the ultrastructure of osteoblastic cell cultures, in collaboration with Jeff Gorski. He also worked with Michael Frotscher on the ultrastructure of the hippocampus. As a senior lecturer he teaches medical science students.
Daniel Studer was mainly interested in improving cryomethods for electron microscopy. He invented the prototype Leica EM PACT high pressure freezer and the microbiopsy system of Leica Microsystems, Vienna, Austria. In addition he invented, with the help of Diatome, Biel, Switzerland, the oscillating diamond knife for ultrathin sectioning. For the latter he received the Ernst Ruska Prize of the Deutsche Gesellschaft für Elektronenmikroskopie in 2005.
