Alan G. Marshall is an American academic chemist who has devoted his scientific career to developing a scientific technique known as Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry, which he co-invented. He is the Robert O. Lawton Professor of Chemistry and Biochemistry at Florida State University and Director of the Ion Cyclotron Resonance Program at the National High Magnetic Field Laboratory. He is a fellow of both both the American Physical Society and the American Association for the Advancement of Science, and has received numerous awards, including the 2007 Chemical Pioneer Award from the American Institute of Chemists. Fourier Transform Ion Cyclotron Resonance, also known as Fourier Transform Mass Spectrometry, is a type of mass analyzer (or mass spectrometer) for determining the mass to charge ratio (m/z) of ions based on the cyclotron frequency of the ions in a magnetic field. ...
