Short Biography

Professor Caram was born in Allentown, Pennsylvania. After high school, Prof. Caram attended Harvard, conducting research with Professors Jim Anderson, studying trace atmospheric radicals, and Vinny Manoharan, studying self-assembled colloidal clusters. He went on to do a PhD at the University of Chicago with Greg Engel, studying quantum coherence using multidimensional spectroscopies.

After a postdoc with Moungi Bawendi as the Robert J. Silbey Memorial Postdoctoral Fellow at MIT, Prof. Caram started his independent career at UCLA in 2017. His group studies how excited states in molecules, molecular aggregates and nanocrystals couple to their environment, using spectroscopies that detect and time individual photons, from the ultraviolet to the shortwave infrared. His group uses these spectroscopic methods to inform chemical design and the synthesis of new materials.

Research Interests

Prof. Caram’s group asks how an excited state couples to its surroundings (its own vibrations, neighboring molecules, ligands, solvent) and whether that coupling can be designed for applications from magnetometry to biological imaging. The group works on three fronts:

Quantum functionality. Molecules whose optical transitions are narrow enough to behave like atoms, such as lanthanide complexes with ultranarrow absorption in room-temperature solution, for sensing and quantum information.

Light beyond the visible. Dyes, self-assembled aggregates and semiconductor nanocrystals that absorb and emit past 1 micron in the shortwave infrared, or in the UV for photoprotection.

Counting photons. Microscopes and spectrometers that detect and time single photons from the visible to the shortwave infrared.

The group is recruiting students who want to develop and apply new spectroscopic methods while making molecules, aggregates and nanocrystals.
