The Keating research group has two major interdisciplinary research themes in the general areas of physical chemistry, colloid and interface science, biological chemistry and materials:
(1) Cytomimetic chemistry, with an emphasis on experimental model systems for subcellular microcompartmentalization, and
(2) Self- and directed assembly of particles, with an emphasis on bridging top-down and bottom-up fabrication approaches for multicomponent functional structures.
Click on one of the areas above, or from the menu on the right, to learn more. Our home is in the Chemistry Department at Penn State University, and we are affiliated with the Huck Institutes for the Life Sciences, the Materials Research Institute, and the Center for Nanoscale Science (an NSF supported MRSEC). Prof. Keating also serves on the graduate faculty of the Bioengineering Department.
