Euan McLeod is directing the Soft Nano-Photonic Systems Laboratory, which focuses on the intersection of nano-photonics, soft materials science, and the coordinated interaction of systems of many components. Two main avenues of investigation include 3D optical assembly of devices from nanoscale building blocks, and the use of lensfree holographic on-chip imaging for the high-throughput sensing of viruses and nanoparticles. The research is pursued using a mixture of experimental and computational approaches. The group seeks to provide cost-effective and high-throughput optical methods of fabrication and sensing based on cutting-edge optical phenomena.
