[1][2] Fenyö's research focuses on the development of methods to identify, characterize and quantify proteins and in the integration of data from multiple modalities including mass spectrometry, sequencing and microscopy.
[3][4][5][6] Fenyö studied engineering physics, with a focus on mathematical and numerical methods, at Uppsala University in Sweden.
in 1987, he joined the laboratory of Bo Sundqvist at Uppsala University, and studied the mechanisms of ion–solid interaction both experimentally,[7] theoretically[8] and using molecular dynamics[9][10][11] and Monte Carlo simulations.
He then went on to complete his postdoctoral work at Rockefeller University with Brian Chait where he developed algorithms to analyze proteomics data obtained using mass spectrometry,[13][14] developed a statistical method for protein identification,[15][16] and applied modeling and simulations to optimize proteomics experimental design[17] and study replication in yeast[18] In 1997, Fenyö co-founded the bioinformatics start-up ProteoMetrics, LLC, and served as the President of the company until 2002 during which he developed software systems for automated analysis of large-scale proteomics data.
[19] Subsequently, he served as the Director of Proteomics at Genomic Solutions, and as Staff Scientist and Product Manager at Amersham Biosciences and GE Healthcare before returning to Rockefeller University in 2005 and joining the faculty of NYU in 2010.
