“Molecular Markers and Environmental
Geochemistry” Dr. M. Indira Venkatesan Research Geochemist Dr. Venkatesan’s major research interests are petroleum and environmental geochemistry.
Her research at UCLA over two and a half decades has focused on the
characterization of organic carbon compounds in order to identify their
sources and to understand their fate in a variety of oceanic regimes, lacustrine deposits, peat, lignite, coal as well as in
oil seeps. She has conducted extensive studies on the historical trends in
the deposition of contaminants in the Dr. Venkatesan has just
completed a study on the distribution of pollutants such as DDTs,
PCBs and a few other chemical
compounds in the surface sediments of ‘Molecular markers’ or specific organic compounds can provide information about the sources of organic material in the environment. Dr. Venkatesan’s lecture will discuss how these various chemical markers can be used to understand the environment as well as to assess the impact of human activities on it. Case studies will be presented to illustrate the application of this approach.
Lecture: 4:00 PM |
