I am pursuing my PhD in Library and Information Science from the University of Pittsburgh with a focus on ontological visualization. Social community tagging and classification research is my current research pursuit. I have experience indexing in archives, museums and libraries for over five years and taxonomy and machine learning for 2 years. I have helped reorganize and reestablish taxonomies and indexing practices for a number of projects that include NATO, SAE International, and NASA. I am also actively researching automatic and traditional indexing practices, bilingual taxonomies, and linguistic studies.
