Darryl Hannan

Bio

I'm a Postdoctoral Research Assistant at Pacific Northwest National Laboratory in the Foundational Data Science Group. I received my PhD from Drexel University as a NSF GRFP Fellow and member of the SPARSE and TAIL labs, and my Master's degree from UNC as a member of the MURGe-Lab. My primary research interests are in vision-language modeling, biologically-inspired learning approaches, and few-shot learning. Some of my recent projects have focused on machine unlearning, data augmentation, and robust object detection.
