Paul Frank Barbara (April 24, 1953 – October 31, 2010) was an American chemist.
His research interests focused on the understanding of the molecular structure and dynamics of complex chemical systems, including organic semi-conductors for photovoltaic applications, proton and electron transfer reactions, the hydrated electron and intermediates in the reverse transcription mechanism of HIV-1.
His laboratory developed and applied novel ultrafast and single molecule spectroscopies to study the complexity of these chemical system.Paul Barbara was a full professor at the University of Texas at Austin.
He held the R.J.V.
Johnson-Welch Endowed Chair in the Department of Chemistry and Biochemistry at UT-Austin.
He was also Director of UT-Austin’s Center for Nano- and Molecular Science and Technology, and Senior Editor for Accounts of Chemical Research.
