Welcome to the Roberts Group!

The Roberts group develops new nonlinear optical techniques to investigate energy and charge transfer in molecular materials.  Projects currently underway in the group include the development of techniques that can look at dynamics at buried interfaces in thin film electronics and building time-resolved Raman spectroscopies to look at ligand-nanocrystal interactions and singlet fission in molecular films.

December 2020: New funding! The group receives a seed grant from UT's APX program to work with Michael Cullinan's group in Mechanical Engineering to examine how mechanical deformation of molecular semiconductors can be used to tune their electronic properties.

December 2020: Congrats to Jon who defends his PhD thesis focused on how thin film morphology controls singlet fission. Congrats Dr. Bender!

October 2020: Words of welcome are in order for Yan Li, a first year chemistry graduate student who will join the group this Fall. Yan will be co-supervised by Zachariah Page and will investigate photocatalyst dynamics!

August 2020: The group officially joins the Center for Dynamics and Control of Materials via their seed grant program. This award will support the group's work investigating singlet fission materials for quantum information applications!

August 2020: Congrats to Emily and Danielle! A collaborative paper describing their work with the Page and Yost groups looking at triplet forming dyes for photocatalysis is accepted by JACS. Great work!


July 2020: The group, along with Carlos Baiz at UT Austin and James Batteas at Texas A&M are awarded an MRI grant by the NSF to fund development of a transient absorption microscope for imaging femtosecond dynamics on nanometer length scales. The microscope will be developed in collaboration with the CDCM, UT Austin's MRSEC. You can check out UT's Press Release for the award here.

May 2020: Danny's paper examining the structure of perylenediimide thin film interfaces using electronic sum frequency generation is accepted by JPCC. Congrats Danny!

May 2020: Michelle successfully defends her PhD Thesis examining hot electron dynamics within Plasmonic Metal Oxide Nanocrystals. Congrats Dr. Blemker!

March 2020: Congrats to Michelle and Emily! Their collaborative paper with the Milliron Group examining electron heating in indium tin oxide nanocrystal films is accepted by ACS Photonics. Nice work!


October 2019: Congratulations to Emily! Her paper describing triplet fusion photon upconversion using Silicon Quantum Dots is accepted by Nature Chemistry. This paper represents a collaboration between our group and Ming Lee Tang's group and Lorenzo Mangolini's group at UC Riverside. You can check out UT's press release on the work here.
