PALEOBIOLOGY

Archean sediments of Timmins (Canada):  Are Archaean biomarkers myth or reality?
Collaborating with Luke Handley in the UIC Department of Chemistry, and using his full spectrum laser desorption with laser postionization-mass spectrometer (fs LDPI-MS), we will map organic compounds in Late Archaean samples from the Abitibi Greenstone Belt in Timmins Ontario, Canada. These samples were previously studied by Todd Ventura (see Ventura et al. 2008 PNAS 104, 14260-14265) so we have a good view of the existing contaminants and the compounds having potential for being Archaean. Using fs-LDPI-MS we will will be able to determine what represents original biomarkers and what represents post-depositional contamination in these 2.65 billion year old sediments. This project forms the basis of Joey Pasterskli's Ph.D. thesis.    

PALEOOCEANOGRAPHY

Biomarker reconstruction of water column structure and dynamics: Upper Devonian- Lower Mississippian of North America. This a long running project in the laboratory, with previous studies of the Cenomanian-Turonian Western Interior Seaway, and now a concentration on the frequency of photic zone anoxia in the depositional centers  of intracratonic basins of North America during  Upper Devonian-Lower Mississippian.  

BIOGEOCHEMISTRY

Metabolomics: Metabolomics is the study of metabolites for the purpose of identifying active processes in an ecosystems. This approach is applied to the cold brine (-13.4 ˚C) of Lake Vida (Victoria Valley, Antarctica), in which a very slow growing microbial ecosystem was characterized (Murray et al. 2012). This project will integrate metabolomics, metagenomics. and geochemistry; it is carried out by Luoth Chou as part of her Ph.D. research.   

 ENVIRONMENTAL and FORENSIC

Natural attenuation and toxicity of parking and road crankcase oil stains: This project is led by Muna Zabarmawi and forms the basis of her PhD research.

PALEOKARSTS and SEDIMENT FILLS in the ORDOVICIAN of  ILLINOIS

The Paleokarsts and Sediment Fills project is driven by Roy Plotnick (UIC) and Fabien Kenig (UIC) with the collaboration of Andrew Scott (Royal Holloway, UK) and Ian Glasspool (FMNH at the time; now Colby College). This project led to many publications in the field of paleobotany, stratigraphy, and paleobiogeochemistry because of the excellent, uncompressed preservation of plant fossils and the remarkable preservation of plant and arthropod tissues.  We are continuing to monitor quarries of North East Illinois for paleokarst features.
