Professor Salzberg's primary research projects concern algorithms for improving the performance of the database kernel. Currently, she is focusing on spatial and temporal indexing, extending her work to branched and temporal databases, in which old versions of data can be updated to create new database branches. This might be used to track the states of various software system configurations as, for example, users branch from a common initial setting.
Her algorithms for spatial and temporal indexing, and for index concurrency, have been featured in several top-ranked, highly selective conferences, as well as in journals. She has been invited to contribute the chapter on indexing in the Handbook on Computer Science and Engineering and has coauthored a survey article on temporal indexes for Computing Surveys.
Professor Salzberg has also been researching online reorganization and the logging necessary to prevent loss of data consistency if a system failure occurs during reorganization. She and Chendong Zou, her former student, have developed algorithms providing detailed instructions about log information needed to make reorganization safe.
Professor Salzberg chairs the IEEE's Technical Committee on Data Engineering and was an associate editor of its Data Engineering Bulletin.
