Our bodies contain trillions of cells. They interact in an intricate network that forms the foundation of our organs and lets our bodies adapt to change. We want to know how it all works by peering inside this hidden world.

Janelia is starting a new 15-year research area, called 4D Cellular Physiology. Our goal will be to understand the function, structure, and modes of communication of cells in organs and tissues with an aim of expanding our understanding of cells and how they collectively give rise to the physiological functions of the body. With its founding mission of connecting biologist and tool builders, we believe that Janelia is uniquely positioned to overcome current barriers and make discoveries at the interface of three classic fields– cell biology, physiology, and anatomy.


4DCP Workshops

Join us as we learn about open frontiers at the nexus of cell biology, physiology, and anatomy. What are the pressing questions? Are there technical barriers blocking scientific progress? Over the coming year, we will hold a series of small, two-day virtual planning workshops with scientists from within and beyond the HHMI/Janelia community. They will be open to the scientific community, so come learn and brainstorm with us!



We look forward to welcoming many new junior and senior group leaders who will set up labs in 4D Cellular Physiology and other research areas at Janelia. We anticipate beginning our recruitment effort in Fall 2021.
