Research Interests
My research has a dual focus on: 1) modeling, extracting, and leveraging high quality information from
unstructured text and 2) applying graph algorithms to information extracted from structured text, both to
facilitate knowledge discovery.
Education
Wright State University
Ph.D. in Computer Science

Aug. 2001 – May 2005
Projects
1. Obvio: Semantic Web in Literature-Based Discovery (2010.6 - 2014.12)
I was the lead PhD student on the Obvio project, whose goal is to leverage assertions from biomedical
literature together with statements from structured background knowledge to facilitate knowledge
discovery. These representations enable reasoning and application of graph algorithms such as depth first
search and hierarchical agglomerative clustering, to automatically create subgraphs along multiple thematic
dimensions. Obvio facilitated the recovery of 8 out of 9 existing scientific discoveries using public literature.

2. PREDOSE: PREscription Drug abuse Online-Surveillance and Epidemiology (2011.7 - 2014.12)
I was also the lead PhD student on the PREDOSE project, which is designed to model, extract and
analyze semantic information on prescription drug abuse from web forum discussions. This research utilizes
rule-based and pattern-based techniques to automatically extract diverse data elements from unstructured
text, such as entities, triples, sentiment expressions, frequency and dosage. The project has contributed
new knowledge on prescription drug abuse based on our analysis of informal web forum posts.

Video Demo: http://bit.ly/predemo & http://bit.ly/kasdemo
3. Scooner: Semantic Browser (2009.1 - 2010.6)
I was previously a Web Developer and then lead PhD student (2010.1 - 2010.6) on the Scooner project,
which is a discovery support system for user-driven text exploration. Scooner performs various tasks,
including entity annotation, semantic trailblazing, fact aggregation and collaborative information sharing.

Video Demo(s): http://bit.ly/scodemo
4. SEMEF: SEMantic Expert Finder (2006.6 - 2007.12)
I also developed SEMEF, which is a semantic web application that leverages structured background
knowledge, bibliographic citations and their associated keywords, to find experts, create expertise profiles
and expand collaboration networks. SEMEF was used to suggest unknown experts for membership on
program committees.
