Computer Scientist
Phone Number: (
Expertise and Research Interests: 

Mr. Mork is currently the lead developer and technical project lead for the Medical Text Indexer (MTI) project.  The MTI project is a multi-divisional team developing the MTI program to assist indexers and catalogers in assigning keywords to over 600,000 biomedical related articles and books each year.  Mr. Mork’s research interests include information retrieval, natural language processing, and extracting information from biomedical literature.

Mr. Mork received his BS in Computer Science from Central Michigan University in 1984 and his MS in Computer Science from The Johns Hopkins University in 1988.

Mr. Mork’s previous experiences at Rapid Systems Solutions, Inc., Century Computing, Inc., VisionQuest Consulting, Inc., and previous Government employment have covered most aspects of Computer Science and Project Leadership.  His main focus has been on Rapid Application Prototyping.
