Ruedi Aebersold

Rudolf Aebersold (better known as Ruedi Aebersold born September 12, 1954 ) is a Swiss biologist, regarded as a pioneer in the fields of proteomics and systems biology. He has primarily researched techniques for measuring proteins in complex samples, in many cases via mass spectrometry. He is probably best known as one of the inventors of the Isotope-Coded Affinity Tag (ICAT) technique for proteomics, a technique for measuring the relative quantities of proteins in one sample relative to another sample by using tags containing stable isotopes of different masses.
