Introduction to Janelia Research Campus
Part of the Howard Hughes Medical Institute (HHMI), Janelia Research Campus is a world-leading interdisciplinary research center dedicated to advancing neuroscience, cellular physiology, imaging science, and computational biology. Located in Ashburn, Virginia, Janelia was established to create a collaborative scientific environment where biologists, physicists, chemists, engineers, and computational scientists work together to solve some of biology’s most complex questions.
Janelia’s research model emphasizes small collaborative laboratories, long-term scientific freedom, and the development of transformative technologies that accelerate discovery across the life sciences. The campus is internationally recognized for pioneering innovations in microscopy, neural circuit mapping, fluorescent probes, image analysis, and large-scale biological data science.
State-of-the-Art Research Facilities
Janelia provides researchers with access to cutting-edge scientific infrastructure designed to support ambitious, high-impact research. The campus features advanced laboratories, collaborative workspaces, computational facilities, vivarium services, and specialized imaging cores integrated into a highly interactive research ecosystem.
Its support teams work closely with scientists to provide customized instrumentation, software development, tissue preparation, microscopy workflows, and large-scale data analysis. Facilities include:
- Advanced light microscopy and electron microscopy suites
- High-performance computing and large-scale data storage systems
- Anatomy and histology laboratories
- Cell and tissue culture facilities
- Instrument design and fabrication workshops
- Animal research and vivarium resources
The campus itself was intentionally designed to foster creativity and collaboration, combining modern research architecture with residential housing, conference spaces, and community amenities that support scientific exchange and innovation.
Advanced Imaging Technologies
Janelia is globally renowned for developing breakthrough imaging technologies that enable researchers to visualize biological systems with unprecedented speed, depth, and resolution. Scientists at Janelia have pioneered and refined numerous advanced microscopy approaches, including:
- Lattice light-sheet microscopy
- Adaptive optics imaging
- Super-resolution microscopy
- Two-photon microscopy
- Simultaneous multiview light-sheet imaging (SiMView)
- Focused ion beam scanning electron microscopy (FIB-SEM)
- Whole-brain and subcellular imaging technologies
Janelia researchers also develop innovative molecular imaging tools, fluorescent dyes, biosensors, and genetically encoded indicators that are now widely used by laboratories worldwide. Technologies such as Janelia Fluor® dyes, Voltron voltage indicators, and IsoView microscopy have significantly expanded the ability to study neural activity and cellular dynamics in living systems.
Advanced Imaging Center (AIC)
The Advanced Imaging Center (AIC) at Janelia provides scientists from around the world with access to pre-commercial imaging technologies and expert microscopy support. The center enables visiting researchers to perform high-risk, high-impact imaging experiments using instruments developed at Janelia before they become commercially available.
The AIC supports a wide range of advanced imaging applications, including live-cell imaging, developmental biology, neuroscience, and quantitative microscopy. Visiting scientists also receive technical guidance, data analysis support, and training from Janelia imaging experts.
Training, Workshops, and Scientific Community
Training and scientific exchange are central to Janelia’s mission. The campus hosts international workshops, conferences, graduate programs, postdoctoral training opportunities, and hands-on microscopy courses designed to advance the global scientific community.
Programs such as the AIC microscopy workshops introduce researchers to modern quantitative imaging, machine learning-based image analysis, light-sheet microscopy, super-resolution imaging, and computational imaging workflows. Janelia also partners with universities and research institutions to support graduate education and interdisciplinary scientific training.
Through its unique research culture, open-science philosophy, and commitment to technology innovation, Janelia Research Campus continues to shape the future of biological imaging and neuroscience research worldwide.
