Peter's primary research interests center around synthesis to enable the study of emergent properties from mesostructured electronic and magnetic materials. He also works extensively on in situ synchrotron x-ray characterization of the formation processes for such materials, with the goal of understanding the pathways to structure formation to enable more advanced syntheses.

Most recently, he has focused on exploring the impact of mesoscale ordering on superconductors. Superconductors with gyroidal mesoscale crystallographic order are expected to exhibit several interesting emergent properties, including angle-dependent forces as field lines align with the pore axes of the material, increased critical fields, and potentially novel flux pinning behavior. Exploration of this area has been extremely limited, however, due to extreme difficulty in preparing such materials. In early 2016, Peter and a team of colleagues from Cornell published the first report of a block copolymer-derived synthesis of such materials in Science Advances. He has worked in recent years to expand the synthesis approach to use the commercially available Pluronics family of block copolymers and use understanding from in situ x-ray studies to improve the synthesis in other ways.

Peter is currently on a six-month DOE SCGSR fellowship at the National Renewable Energy Lab, where he is applying his expertise in organic-inorganic synthesis and x-ray characterization to single crystals of organolead halide perovskites.
