Serguei Popov
Founder of IOTA Foundation
Serguei Popov is a research mathematician working in the field of Probability Theory and Stochastic Processes. He graduated from and attained his Ph.D. at the Moscow State University under the supervision of Professor Mikhail Menshikov. Around 20 years ago he moved to Brazil to do a postdoc, and then progressed to professorship first in the University of Sao Paulo, and then in the University of Campinas. Serguei began his interest in cryptos in late 2013 when, after stumbling upon an article about Bitcoin, he became an avid reader of bitcointalk.org and discovered an innovative project called Nxt. He achieved notoriety in the Nxt community after publishing a short note with calculations on the block generating process in Nxt (a revised and expanded version of these notes can be found here). Together with the founder of the Nxt and other people from the Nxt community, he co-founded IOTA in 2015.
