Dr. Tiffany J. Callahan is currently a Postdoctoral Research Scientist at IBM Research. She recently received her Ph.D in Computational Biology from the University of Colorado Anschutz Medical Campus. Her PhD thesis leveraged graph representation learning and neural-symbolic reasoning of large-scale biological knowledge graphs in order to develop realistic estimates of human disease mechanisms. Her research interests include computational biophysics, multimodal generative AI, representation learning, and probabilistic mechanistic modeling. She is a lover of all things Semantic Web, an advocate of FAIR transparent science, and an avid supporter of open source development. The Health Data Compass, National COVID Cohort Collaborative, and the HuBMAP Consortium are some of the organizations currently utilizing her software.
