* Developed various services that made up a high capacity document processing pipeline for the analysis of public social media and news feeds. Focused on writing applications as services,using a combination of embedded HTTP server libraries, the ZeroMQ library, and low-level TCP socket programming around custom protocols.* Rewrote the NLP engine's lexical analysis components around a faster and more space efficient Directed Acyclic Word Graph data structure.

* Software configuration management: Directed the migration of the company's revision control system from CVS to Git. Directed the migration of the issue tracking system from Bugzilla to Redmine. Gatekeeper for the main Git repository. Build and release manager.* Architecture, maintenance, and development of the company's core information extraction and text analysis engine.

* Managed a team responsible for developing linguistic knowledge resources (annotation rules) used by a proprietary NLP engine.* Primary architect, developer, and maintainer of system components for pattern matching in tree structured and graph structured data, as well as the development tools (compilers, debuggers, pretty printers, etc.) used by the team.* Also served as Principle Investigator on a number of government-sponsored research projects (the most recent of which… Show more * Managed a team responsible for developing linguistic knowledge resources (annotation rules) used by a proprietary NLP engine.* Primary architect, developer, and maintainer of system components for pattern matching in tree structured and graph structured data, as well as the development tools (compilers, debuggers, pretty printers, etc.) used by the team.* Also served as Principle Investigator on a number of government-sponsored research projects (the most recent of which was completed in early 2012). Conceived project plans, wrote proposals, as well as reports. Project topics included extraction and normalization of date and time expressions, real-time text analysis of chat message streams, and domain adaptation to certain types of military message traffic.

* Developed and maintained a rules engine for pattern/action parsing and annotation rules on tree structures, various domain specific languages for specifying such annotation rules, and a suite of development tools for developing linguistic knowledge resources around that engine.* Worked on a number of government-sponsored research projects, with topics including the recognition and normalization of time and date expressions, and the recognition and annotation of events mentioned in… Show more * Developed and maintained a rules engine for pattern/action parsing and annotation rules on tree structures, various domain specific languages for specifying such annotation rules, and a suite of development tools for developing linguistic knowledge resources around that engine.* Worked on a number of government-sponsored research projects, with topics including the recognition and normalization of time and date expressions, and the recognition and annotation of events mentioned in texts.

* Research mainly focused on formal and computational properties of logic-based formalisms for describing human knowledge of language.* Also taught an Introduction to Programming in Prolog course. Mainly worked in the Prolog logic programming language, and studied various kinds of tree automata, which later provided the formal foundation for the annotation rule engine at Cymfony and Janya.

* Research focused on the computational modeling of language breakdown resulting from brain damage, mainly aphasia.* Also researched approaches to natural language parsing based on constraint satisfaction algorithms.
