Fabrizio Chiti (born in Florence, 7 July 1971) is an Italian biochemist noted for his work on Protein aggregation and amyloid.^[1]

Chiti is a graduate in Biological Sciences of the University of Florence (Italy).^[2] He attained a PhD degree (D.Phil) in Chemistry in 2000 at the University of Oxford in UK.^[2] He then worked as a postdoctoral researcher at the University of Florence, Italy, with Giampietro Ramponi as a supervisor (2000–2002) and at the University of Cambridge, UK, under the supervision of Chris Dobson (2002).^[2]

He was appointed as an Associate (2002) and then Full Professor (2010) at the University of Florence in Biochemistry.^[2] Chiti provided contributions in the field of misfolding and aggregation, particularly in the field of amyloid^[1] He rationalized how amino acid mutations induce protein aggregation and edited an equation to predict the effect of mutations on the aggregation of an unfolded protein,^[3][4] which led to a search by many investigators of algorithms with predictive power on essential aspects of protein aggregation. He also correlated the toxicities of abnormal protein oligomers with specific structural properties of them.^[5] His 2006 review with Chris Dobson on protein misfolding, amyloid formation and human disease,^[6] later updated as a new report,^[7] is a reference paper in the field of amyloid and received, as of October 2019, more than four thousands citations in scientific publications.^[1][8]
