Major Responsibilities: 

My research interest is to study paleoclimate changes during the last deglaciation through examining loess-paleosol, dune-wetland, and lacustrine-marl successions in mainly Illinois, United State. The objectives of my research are 1) to establish intra-chronozonal climate records at places progressively moving towards the retreating ice margin of the Laurentide Ice Sheet; 2) to understand biogeochemical cycles in these successions for paleoclimate proxy studies. I use radiometric (conventional) and accelerator mass spectrometry (AMS) radiocarbon and optically stimulated luminescence (OSL) dating technologies for chronology study and use stable isotope geochemistry and other geochemistry and geophysics techniques for developing proxies.  

Dune-wetland succession at the Manito site in the middle Illinois River Valley and Loess-paleosol succession at the Keller Farm site in the middle Mississippi River Valley reveal climate changes on intra-chronozonal levels.

Top two panels show the Manito dune site and proxy results and bottom two panels show Keller Farm loess and Bon Harbor (proxy only) loess sites in Mississippi and Ohio River Valleys through collaborating with Kentucky Geological Survey. 

We are working on AMS 14C dating on root residue trapped inside of rhizoliths, indicated by arrows, and inner layers of calcified roots or solidified plant-genic CO2, indicated by oval circles, and individual calcified roots in figures below for loess chronology studies.

Rhizoliths

Rhizoliths: cementation of calcified roots; arrows: root residue; oval circles: calcified rootlets. Individual rootlets; SEM: calcified root and fungi cells; EDS: calcium in the matrix of calcified roots; Cathodoluminescence: multi-generations of calcite.
