Alexander D. Diehl, PhD, assistant professor of neurology, is contributing his expertise to a UB team developing ontologies—uniform, agreed-upon systems of meaning—related to immunology and infectious disease.
Selected by the National Institutes of Health (NIH), the UB group also will train researchers in the use of these systems.
With the ultimate goal of accelerating scientific discovery, these ontologies will allow scientists investigating immunology and immune-mediated diseases to speak the same language, exchange data and compare research results.
The UB work is part of an international, interdisciplinary effort funded by the National Institute of Allergy and Infectious Diseases through its Bioinformatics Integration Support Contract (BISC).
The five-year contract has a maximum potential value of $30 million.
The immunology ontologies are part of a larger NIH project centered on ImmPort, the Immunology Database and Analysis Portal.
This integrated database aims to broaden the usefulness of life sciences data, creating a more collaborative, coordinated research environment across geographic and disciplinary boundaries.
"The immunology ontology effort brings together work I and
others have done on separate ontologies such as the Cell Ontology,
Gene Ontology and Infectious Disease Ontology over the last decade
to create a unified terminology for describing and analyzing
immunology and infectious disease data," Diehl explains.
"This will enhance access to and reuse of the data by ImmPort users and the scientific community as a whole."
Diehl has worked to develop and apply various types of ontologies for molecular biology, immunology and neurobiology, including ontologies representing neurological diseases, infectious diseases, cells and proteins.
He leads an ontology project to represent in vivo cell types, particularly hematopoietic cells and neurons.
Such scientific ontologies are crucial because “there is no universal, standard terminology in medical and related fields,” explains Barry Smith, PhD, Julian Park Professor of philosophy, who is leading the UB project.
“The way a term is used may be particular to a research area or even a specific research group,” he says. “This makes it difficult for scientists to communicate with one another and share, find or compare data.”
Smith also directs the National Center for Ontological Research and serves as an adjunct professor of neurology and computer science.
The UB team also includes Alan H. Ruttenberg, director of clinical and translational data exchange in the School of Dental Medicine.
The entire BISC project is led by Atul Butte, MD, PhD, chief of systems medicine in the Department of Pediatrics at Stanford University.
Other partners are Northrop Grumman Information Technology and scientists from the Technion Israel Institute of Technology, the University of California, Berkeley, and the University of Vermont.
