This year’s CIFAR MacMillan Multiscale Human (MHU) School will be held on May 5-6, 2026 in Vancouver, Canada. This school brings together trainees of CIFAR’s MHU program, as well as PhD students and postdoctoral fellows across the globe with interests in early embryonic development to delve into the challenges and gold standards of human research, exploring interdisciplinary approaches that bridge experiments and theory to build a virtual twin that accurately captures development. The school will highlight the latest research and tools, discussing necessary collaborations for success in creating these models. Participants will enhance their communication skills to engage with diverse fields and learn to decompose complex biological problems. Participants will also experience debates on topics such as the role of AI in solving problems or discussing the necessity of "real" in vitro systems in the lab. By emphasizing storytelling and collaboration, the program aims to equip students with the tools necessary to navigate discussions on various topics in developmental biology and related fields. CIFAR will cover the cost of travel, meals and accommodation associated with this school.
