works focuses on mathematical, philosophical,
and practical problems with risk and probability, as well as on the
properties of systems that can handle disorder. He
spent 21 years as a derivatives trader and, after closing 650,000
option transactions and examining 200,000 risk reports, he changed
careers in 2006 to become a mathematical researcher, scholar and philosophical essayist.
is currently Distinguished
Professor of Risk Engineering at New York University’s Polytechnic
Institute, co-director and founder of the EXTREME RISK INITIATIVE-NYU
SCHOOL OF ENGINEERING, and co-editor in chief of the scholarly journal Risk and Decision Analysis.
He is the author of a 4 volume philosophical essay on uncertainty, Incerto (Antifragile (2012), The Black Swan (2007–2010), Fooled by Randomness (2001) and The Bed of Procrustes (2010)) as well as a mathematical parallel version, Silent Risk (freely available). His collected scientific papers are here. Most recent activity: collaborated with the Rand Corporation on a project for the early detection of country fragility.
Fields: Decision theory/risk/probability/fragility.
What to do under incomplete understanding ("opacity"), epistemology of probability, mathematical expressions of model errors and metaprobability, ancient heuristics & Mediterranean systems of ethics.
