Our research interests are centered on gaining new understanding of the progression and mechanisms of environmental and climate change in the past 250,000 years of Earth's history. Investigations are often collaborative, bridging multiple disciplines, and combine field interpretations and analytical measurements, with geophysical modeling. This approach underscores the importance of translating site-specific geomorphic or stratigraphic observations or measurements to regional and global contexts on various time scales. We see an endless horizon of exciting and significance science, much, if not all collaborative with students and colleagues from many continents.

The accurate and precise measuring of geologic time is a critical component in the earth sciences. A long-standing research focus is the development and application of luminescence geochronology to decipher the timing of late Quaternary (past 250 ka) climatic and environmental events, such as paleoearthquakes, volcanic eruptions, floods, lake level oscillations, fluvial degradation and aggradation, eolian deposition, burial of paleosurfaces, droughts and periods of human habitation. Analytical approaches employed include recent advances in optically stimulated luminescence using small aliquots of quartz and single grain dating. Recent research is tapping deeper trapped electrons in quartz and feldspar using the thermally-transferred signal which extend dating possibilities to 1 to 2 million years. The research horizons from the vantage point of luminescence physics is broad and deep, with recent collaborations on understanding the source of charge with triboluminescence and electron storage potential for synthetic silica nano-compounds for solar cells.
