John B. Fenn Distinguished Contribution

John Fenn_opt

The ASMS Award for Distinguished Contribution in Mass Spectrometry is named to honor the memory of John B. Fenn who shared the 2002  Nobel Prize for the development of electrospray Ionization. John joined ASMS in 1986 and remained an active member until his passing in 2010. 

The John B. Fenn Award for a Distinguished Contribution in Mass Spectrometry recognizes a focused or singular achievement in fundamental or applied mass spectrometry in contrast to awards that recognize lifetime  achievement. Eligibility is restricted to members of ASMS. Nominations will be held for three years. The award is conferred at the ASMS Annual Conference with the presentation of a $10,000 cash award, a recognition plaque, and the award lecture.

Nominations are due November 30.  Nomination Form (PDF fill-in form).

Evan R. Williams, 2022 Recipient

Fenn_WilliamsEvan R. Williams is the recipient of the 2022 ASMS John B. Fenn Award for a Distinguished Contribution in Mass Spectrometry for the development of ion chemistry in aqueous nanodrops:  fundamentals and applications. Dr. Williams has made pioneering contributions that have improved our fundamental understanding of ion chemistry in aqueous nanodrops both inside and outside the mass spectrometer. His work has had tremendous impact and represents a cohesive and successful sustained effort to understand the chemistry occurring in aqueous solution during the transition in the electrospray process from bulk solution to individual ions or solvated ions. 

He has taken advantage of nanodrop chemistry to: 1) manipulate ion charging and desalting ions during the electrospray ionization process, 2) develop rapid mixing in electrospray droplets to investigate ultrafast chemistry (<1 to 100 microseconds) to track peptides and fast-folding proteins in the act of folding, 3) investigate how the organization of water around ions can pattern the hydrogen bonding network of water to long distance, and how water can affect the structure of ions, and 4) develop thermochemical methods, including blackbody infrared radiative dissociation and ion nanocalorimetry, to probe the thermochemistry of processes, such as electrochemical reductions in mass selected aqueous nanodrops.

This collective theme has influenced not just the field of mass spectrometry and ion chemistry but has also improved our understanding about the role of water on ion chemistry in solution, an outcome which impacts many areas ranging from biomolecule structure and folding to atmospheric aerosol chemistry.

Dr. Williams is a Distinguished Professor of Chemistry and Biophysics, University of California, Berkeley.
