Research interests and accomplishments

My research interests derive from an interest in formal reasoning. Specific interests include semantics of higherorder programs with effects; formal modeling and analysis of distributed systems; and foundations of first-order reasoning. Methods I have developed for reasoning about imperative, functional, and concurrent programs are now being used by several research groups in the United States, Europe, and Australia.

In [talcott-96hoots-book] I introduced the notion of uniform semantics for imperative functional programs, providing general conditions for a context lemma introduced in [mason-talcott-89icalp] and establishing a basis for a programming logic [mason-talcott-00feferman]. In collaboration with Professors Agha, Mason, and Smith, I developed a formal theory of components of open distributed systems based on the actor model of computation.

In [talcott-96fmoods] two important notions are introduced: actor theories (called abstract actor structures in early papers) and interaction semantics. Interaction semantics abstracts away from the details of internal computation and provides a means of reasoning about actor system components considered as black boxes.

In collaboration with Prof. Venkatasubramanian at UC Irvine, I developed the TLAM reflective actor model for specifying and reasoning about composable middleware services in open distributed systems. The TLAM framework has been applied to a number of substantial case studies including distributed garbage collection [venk-agha-talcott-92iwmm, venk-talcott-95podc] and QoS-based multimedia service [venk-agha-talcott-01fme].

In collaboration with Prof. Smith of Johns Hopkins University, I developed a graphical notation for specification of actor system components called Specification Diagrams [smith-talcott-99fmoods, smith-talcott-02hosc]. This notation is similar in spirit to some of the event/message diagram notations of UML, and has a rigorous semantic foundation for composition, transformation, and checking satisfaction.

In collaboration with Prof. José Meseguer and others I have carried out substantial case studies developing formal models of network protocols and languages [denker-etal-99allerton, denker-meseguer-talcott-00disex, meseguer-olveczky-stehr-talcott-02dance, olveczky-etal-01fase, stehr-talcott-02wrla]. Meseguer and I have developed a model of distributedd object reflection [meseguer-talcott-02ecoop] that is being used in ongoing projects.

Currently I am using the Maude rewriting logic environment to develop and analyze executable formal models of a variety of systems, including: secure mobile agent systems [talcott-lincoln-03hcss], autonomous goal-oriented agents [denker-talcott-04wrla], and signal transduction systems in biological cells [eker-etal-02wrla, eker-etal-03csmb, talcott-etal-04psb].
