Emily Weiss

Adjunct professor of Chemistry, Professor of Materials Science and Engineering (by courtesy)

Ph.D. in Chemistry, Northwestern University, 2005; A.B. in Chemistry, Princeton University, 2000

Research Interests

The Weiss group studies the physical chemistry of semiconductor quantum dots – specifically how we can tune the chemistry at their surfaces in order to control their optical properties. We use ultrafast linear and nonlinear spectroscopies, a range of analytical and structural characterization techniques, and electrical measurements on quantum dots in the solution and solid phases to study the interaction between the nanocrystal core and rationally designed organic ligands on the surface.
