Current Research and Scholarly Interests

Research
The history of life on Earth can be studied in the fossil record and in the chemical fossil record. In our research we study molecular fossils, biomarkers that can provide evolutionary and paleoenvironmental information from the organic component of sediments and petroleum. Current research foci include correlating fossil and molecular fossil records, understanding paleoenvironments and global change, determining the degree of thermal evolution of organic matter, and understanding petroleum biodegradation mechanisms. Our interests also lie in applications of organic geochemistry to understanding sedimentary basins, petroleum systems and reservoir architecture, and to environmental problems related to petroleum.

Teaching
I teach courses related to the subject matter of my research. The technology and its application in aspects of petroleum exploration and production, environmental analysis. Petroleum Geochemistry in Environmental and Earth Science. For those students interested in applying molecular geochemistry in their thesis research I teach a follow-up course called Laboratory Methods in Organic Geochemistry. Courses are taught in our facilities in Rohnert Park, CA, or on-site as appropriate.

Professional Activities
I am currently CEO and President of Biomarker Technologies, Inc., a research and services laboratory dedicated to application of advanced geochemical technologies for paterolrum exploration, development and production and for environmental and remediation monitoring.

M., Barbanti, S. M., Fago, F. J., Denisevich, P., Dahl, J., Trindade, L. A., Schouten, S. 2004; 304 (5670): 584-587

    Abstract

    The 18S ribosomal DNA molecular phylogeny and lipid composition of over 120 marine diatoms showed that the capability to biosynthesize highly branched isoprenoid (HBI) alkenes is restricted to two specific phylogenetic clusters, which independently evolved in centric and pennate diatoms. The molecular record of C25 HBI chemical fossils in a large suite of well-dated marine sediments and petroleum revealed that the older cluster, composed of rhizosolenid diatoms, evolved 91.5 +/- 1.5 million years ago (Upper Turonian), enabling an accurate dating of the pace of diatom evolution that is unprecedented. The rapid rise of the rhizosolenid diatoms probably resulted from a major reorganization of the nutrient budget in the mid-Cretaceous oceans, triggered by plate tectonics.

  • THE MOLECULAR FOSSIL RECORD OF OLEANANE AND ITS RELATION TO ANGIOSPERMS SCIENCE Moldowan, J. M., Dahl, J., Huizinga, B. J., Fago, F. J., Hickey, L. J., Peakman, T. M., Taylor, D. W. 1994; 265 (5173): 768-771

    Abstract

    Oleanane has been reported in Upper Cretaceous and Tertiary source rocks and their related oils and has been suggested as a marker for flowering plants. Correspondence of oleanane concentrations relative to the ubiquitous microbial marker 17alpha-hopane with angiosperm diversification (Neocomian to Miocene) suggests that oleanane concentrations in migrated petroleum can be used to identify the maximum age of unknown or unavailable source rock. Rare occurrences of pre-Cretaceous oleanane suggest either that a separate lineage leads to the angiosperms well before the Early Cretaceous or that other plant groups have the rarely expressed ability to synthesize oleanane precursors.

    Abstract

    24xi--Methylcholestane-3beta, 5alpha, 6beta, 12beta, 25-pentol 25-monoacetate has been isolated from an Alyconarian and its structure was established in part through extensive high resolution mass spectral and nmr studies and partly through the nonidentity of one of its degradation products with 24xi-methylcholestane-3beta, 5alpha, 6beta, 12alpha-tetrol synthesized from deoxycholic acid.
