Ralph JimenezView profile
Adjunct Professor
Ralph Jimenez is an Adjunct Professor of Chemistry and Institute Fellow at JILA, University of Colorado Boulder. He holds a Ph.D. from the University of Chicago (1996) and completed postdoctoral work at the University of California, San Diego (1997-1998), followed by research at The Scripps Research Institute (1998-2003). His research focuses on quantum spectroscopy and photophysics of fluorescent proteins, leveraging quantum optics to enhance spectroscopic sensitivity and developing genetically encoded biomarkers with improved photophysical properties. Key achievements include fluorescence-lifetime-based methods to engineer brighter fluorescent proteins and machine-learning approaches to improve photostability. His awards include the Arthur S. Flemming Award (2017) and U.S. Department of Commerce Gold Medal (2017). His group's work integrates quantum engineering with biophysical studies, targeting real-world applications in molecular imaging and materials science. The Jimenez Group operates labs at JILA (B117, B119, B121) and collaborates on projects involving entangled photons, two-photon absorption, and ultrafast spectroscopy. Research themes include quantum-enhanced spectroscopy for complex systems and overcoming limitations in fluorescent protein imaging through physical chemistry strategies. His lab develops novel instrumentation, including microfluidic sorting systems and tabletop X-ray spectroscopy platforms, to advance biomarker engineering and environmental monitoring.
