Presenting our latest work in #CVPR2022 w/ @rahulgk @ai4pathology & team. We discover ViT pretraining techniques scale well to large image resolutions, opening the opportunity for self-supervision of gigapixel pathology images. arxiv.org/abs/2206.02647 github.com/mahmoodlab/HIPT 1/

Sharing our work on Multimodal Co-Attention Transformers (MCAT) in the 12 - 2 PM poster session @PacSymBiocomp 🌊🌊! MCAT is an interpretable, easy-to-use method for early fusion between pathology and genomics, and readily outperforms concat + bilinear pooling fusion. #PSB23

Seconding @JamesADiao tweet. Had the pleasure to work with @AndrewLBeam and @zakkohane on very unique EMR data! Was pivotal in developing my interest in the ML <> health intersection. Came back to do a PhD :^)
