Summary
👤
Senior🎓
Top SchoolJohn Arevalo is a Principal Machine Learning Scientist with 12 years of experience building predictive systems at the intersection of deep learning, medical imaging, computer vision, NLP and multimodal learning. He holds a PhD in Computer Science and has a track record of influential academic work—including ICLR-published multimodal attention research and highly cited CNN applications for mammography—that has been adopted across architectures like CNNs, RNNs, GANs and Transformers. After foundational research roles across academia and industry, he moved from postdoctoral work at the Broad Institute to applied ML leadership at AI Fund and now leads ML science at Genentech in South San Francisco. An active open-source maintainer early in the Theano era, he improved core libraries like blocks and pylearn2 to enhance usability and backwards compatibility, reflecting a pragmatic focus on reliable tooling as well as novel models.
