E. Allen Emerson has a longstanding interest in formal methods for establishing program correctness. This was inspired in part by reading in the mid-1970's a CACM paper by Tony Hoare "Proof of Program: Find". Also inspirational was a talk by Zohar Manna on fixpoints and the Tarski-Knaster Theorem given in 1975 at the University of Texas.

Emerson has been recognized as co-inventor of model checking , an algorithmic method of verifying nominally finite-state concurrent programs, proposed in this paper [CE81]. Such ongoing finite state programs correspond to the synchronization skeletons of many concurrent, distributed, or reactive programs comprised of multiple processes that must synchronize or coordinate their behavior. Correct behavior is described using a temporal logic, such as CTL (Computation Tree Logic) permitting specification of behavior along all futures versus some futures. In the past quarter century model checking has become a very popular and successful approach to formal verification. His other contributions include new and improved model checking algorithms, abstractions and reductions to simplify the complexity of model checking, decision procedures, and algorithmic methods of program synthesis. Additional interests include model checking symmetric and nearly symmetric systems, verification of parameterized systems, and reasoning about data structures. Emerson is a recipient of the ACM Turing Award, as well as the ACM Kanellakis Prize, the CMU Newell Medal, and the IEEE LI.CS'06 Test-of-Time Award. He serves on the editorial boards of leading formal methods journals as well as conference program committees. He is an Information Sciences Institute Highly Cited Researcher. Emerson is a member of the ACM.

He received his B.S. degree from the University of Texas at Austin in Mathematics and a Ph.D. in Applied Mathematics from Harvard University.
