CRANN, the Centre for Research on Adaptive Nanostructures and Nanodevices, is Ireland's first purpose-built research institute whose purpose is to perform nanoscience research. It is housed in the Naughton Institute on the campus of Trinity College Dublin. Crann is the Irish word for tree.^[1]

The three major research areas are Nano-Biology of Cell Surface Interactions, Bottom-Up Fabrication and Testing of Nanoscale Integrated Devices, and Magnetic Nano-Structures and Devices.

As of 2018, CRANN was led by its director, Prof. Stefano Sanvito, along with deputy director Prof. John Donegan, and executive director Dr. Lorraine Byrne.^[2] Previously,^[when?] the management team consisted of Prof. John Boland (director), Prof. Mike Coey (deputy director), Dr. Jussi Tuovinen (executive director).^{[citation needed]}
