Knowledge Graphs and Semantic Computing Speaker Series: Tiffany Callahan

Tiffany Callahan

Dr. Callahan, a Postdoctoral Research Fellow in the Department of Biomedical Informatics at Columbia University Irving Medical Center, will present "Learning Deep Translational Patient Representations for Rare Disease Classification and Subphenotyping." 

Dr. Callahan received her Ph.D. in Computational Biology from the University of Colorado Anschutz Medical Campus in 2021 and is currently a Postdoctoral Research Fellow in the Department of Biomedical Informatics at Columbia University Irving Medical Center. Dr. Callahan’s Ph.D. 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. She is currently applying these methods to improve the detection, prediction, and understanding of complex phenomena like phenotyping of pediatric rare diseases and adverse event detection.
