Description of Research Expertise

The goal of Dr. Stoeckert's work is to help make sense of the enormous amount of biomedical data. To that end, he is involved in projects that are developing tools that enable researchers to mine and integrate data from a variety of different sources and types of experiments.

The first step in that process is the development of data warehouses that collect and store information in a useable fashion. In one such project, he has been working with David S. Roos, Ph.D., E. Otis Kendall Professor of Biology at Penn, Jessica Kissinger, Ph.D., at University of Georgia, and others to develop a bioinformatics resource center for eukaryotic pathogens, funded by the National Institute of Allergy and Infectious Diseases. Within the resource center, we have built databases that serve research communities interested in specific pathogens. For example, PlasmoDB, houses information on the parasites that cause malaria. He also works with Li-San Wang at Penn on the National Institute on Aging Genetics of Alzheimer's Disease Data Storage Site (NIAGADS).

We also have been involved in the analysis of genomics datasets particularly in the areas of red blood cell development, pancreatic islet cells, and Plasmodium genomes.

To maximize the utility of data warehouses, we must have ways to represent and store data that enables researchers to make connections between experiments and between data from different types of experiments. Therefore, part of my group is involved in knowledge representation and developing ontologies, which standardizes data through the use of controlled vocabularies and relationships. Our goal is to provide the standards, including ontologies, to allow people to annotate their experiments or mark up their papers in a way that another researcher could efficiently search for and combine particular kinds of results from a variety of sources. We have been applying these to clinical epidemiological datasets available through ClinEpiDB.

We work with a number of groups on ontology projects, including the Ontology for Biomedical Investigations Consortium which is a member of the Open Biological and Biomedical Ontologies (OBO) Foundry.

The TURBO (Transforming and Unifying Research with Biomedical Ontologies) project uses the expressive power of ontologies in graph databases to represent and integrate clinical data. Powerful searches of individual medications and diagnosis codes are made possible through association to ontology classes of drug roles and diseases.
