Robert Cava

Princeton University, EPiQS Materials Synthesis Investigator

Materials Synthesis Investigator

Research Description

Dr. Cava directs the Solid State Chemistry Research Group at Princeton University. His group searches for and synthesizes new compounds, grows crystals, determines their crystal structures, and characterizes their electronic and magnetic properties. He has made important contributions to discovery and development of superconductive materials. He was an early worker in “high temperature superconductivity”, determining the chemical formula of the first material to display zero electrical resistance above the temperature of liquid nitrogen (an easy-to-use coolant), and, recently, discovered and developed “topological insulators” – materials whose surface electrical currents appear to be in a unique new quantum state.His research is directed at discovering other novel materials as well, including frustrated magnets, thermoelectrics and transparent electrical conductors.

Dr. Cava has received the Inorganic Chemistry and Materials Chemistry Prizes of the American Chemical Society, the McGroddy Prize in New Materials of the American Physical Society, a Humboldt Research Award, and the John J. Carty Award for the Advancement of Science from the US National Academy of Sciences. He also received a Materials Synthesis Investigator Award from the Gordon and Betty Moore Foundation in 2014.

Dr. Cava earned his PhD from the Massachusetts Institute of Technology.
