Ontology Development Group

The Ontology Development Group in the OHSU Library is an interdisciplinary group led by Dr. Melissa Haendel. An ontology is a formal representation of domain knowledge in the form of concepts and how they relate to each other within the domain.


The Ontology Development Group (ODG) strives to promote research innovations, service development, and education through semantically enabled technologies for the purposes of data management and publication, research reproducibility, and the building of novel tools for biomedical data exploration.

Who are we?

  • Bench scientists turned ontologists[1] and biocurators[2]
  • Computer scientists turned bioinformaticians
  • Medical practioners turned software developers

[1] Ontologist (on·tolo·gist n.) a domain expert who classifies information in a knowledgebase

[2] Biocurator (bio·cu·ra·tor n.) a professional scientist who collects, annotates, and validates data that is disseminated by biological databases or journals

Upcoming Events:

ODG and the OHSU Library have hosted several working sessions to address data reproducibility and research communication. The goal is to promote interaction between information scientists and research scientists to support enhanced awareness of data stewardship. This event is funded by an award from Force11.

Hands-on data management sessions with OHSU Library Staff

Participants are eligible to receive a $50 gift card.
