Constructing and Characterizing a Scanning SQUID Microscope for a Cryogen Free Dilution Refrigerator
Superconducting quantum interference devices, or SQUIDs, are highly sensitiveto magnetic flux and can be used to perform magnetic imaging at cryogenic tem- peratures. In this dissertation, I describe the first scanning SQUID microscope in a cryogen-free dilution refrigerator. First, I briefly …

Superior to one of Glass: Natural Gradient index Lenses via Patchy Particle Self-Assembly
… light in order to maintain transparency. In squids, this sophisticated optical design emerges from the properties of a single protein fold, the S-crystallin. In this thesis, I study the material properties and the self-assembly of the squid lens system. I show that squids have evolved graded …
