Hemamala Karunadasa

Early life and education Karunadasa grew up in Colombo. She attended high school in Sri Lanka and was a student at Ladies' College, Colombo. She thought that she would become a doctor, and eventually decided to apply to university in America. Cava's excitement about research inspired Karunadasa to continue her own academic career. Karunadasa continued her work on water-splitting electrocatalysts with Jeffrey R. Long and Christopher Chang as a postdoctoral fellow. The molybdenum-oxo metal complex synthesized by Karunadasa is around seventy times cheaper than platinum, the most commonly used metal catalyst in water splitting. She then moved to the California Institute of Technology, where she worked on catalysts for hydrocarbon oxidation with Harry B. Gray as a BP Postdoctoral Fellow. Karunadasa is interested in ways to mitigate these shortcomings, and any transient changes that may occur when these materials absorb light. In these systems the organic small molecules are sandwiched between the sheets. In the case of thick inorganic sheets, the inorganic materials act as absorbers, and enhance the stability of the perovskite materials. The organo-metal-halide perovskites created by Karunadasa and her collaborator Michael D. McGehee can be processed in solution. She believes that through careful chemical design it is possible to determine the fate of photogenerated charge carriers. Karunadasa has investigated the lifetimes of acoustic phonons in lead iodide perovskites with Michael Toney and Aron Walsh.
