Mathew Debessai

Physicist and co-author of both a 2009 Physical Review Letters paper reporting superconductivity in europium and the 2020 carbonaceous-sulfur-hydride paper (Snider, Dasenbrock-Gammon, Dias et al., Nature) — the paper Nature retracted in 2022. Per Jorge Hirsch's account, Debessai performed the raw susceptibility measurements underlying both studies and taught Ranga Dias high-pressure measurement technique. Matters to this vault as the physical link between Hirsch's confirmed-by-his-own-account precedent case of data alteration (the 2009 europium paper) and the disputed 2020 CSH data: the same hands are said to have produced both datasets.
