Dr. Bianchi's general areas of expertise are organic geochemistry, biogeochemical dynamics of aquatic food chains, carbon cycling in estuarine and coastal ecosystems, and biochemical markers of colloidal and particulate organic carbon. He has worked in estuarine systems around the world with particular emphasis on the Mississippi River/Louisiana shelf system over the past six years. Some of this work has focused on the fate and transport of organic carbon source inputs to the Louisiana shelf using chemical biomarkers as source indicators, in addition to recent work on the paleo-reconstruction of hypoxia events on the shelf and relationship between carbon cycling in the Mississippi River plume and hypoxia. A recipient of two Fulbright Awards, Bianchi has published over 125 articles in refereed journals and was lead co-editor (Bianchi, Pennock and Twilley) of a 1999 book entitled Biogeochemistry of Gulf of Mexico Estuaries.
He has sole-authored book entitled, Biogeochemistry of Estuaries published in 2007 by Oxford University Press. More recently he was co-author on book by Dale, V., C. Kling, J.L. Meyer, J. Sanders, H. Stallworth, T. Armitage, D. Wangness, T.S. Bianchi, A. Blumberg, W. Boynton, D.J. Conley, W. Crumpton, M. David, D. Gilbert, R.W. Howarth, R. Lawrence, K. Mankin, J. Opaluch, H. Paerl, K. Recknow, A.N. Sharpley, T.W. Simpson, C. Snyder, and D. Wright, published in 2010 entitled Hypoxia in the Northern Gulf of Mexico (Springer Press), and another book as lead co-author by Bianchi, T.S. and E.A. Canuel, published in 2011 entitled Chemical Biomarkers in Aquatic Ecosystems, published by Princeton University Press. Bianchi is currently finishing two other books, one sole-authored to be published in 2012 entitled River Deltas: Sea-Level Rise and Cities in Peril to be published by Oxford University Press (due date in February 2013), and another by Bianchi, T.S., Allison, M.A., and W. Cai. entitled Biogeochemistry of Large-River Delta-Front Estuaries, to be published by Cambridge University Press. (due date December 2012).
Finally, Bianchi currently serves as an Associate Editor for the journals Marine Chemistry and Geochimica Cosmochimica et Acta, and has just accepted the post as Editor-in Chief of journal Estuarine and Coastal Shelf Science.

Chemical Biomarkers in Aquatic Ecosystems
This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosytems consists of a biogeochemical approach that has been quite successful but underused.
Hypoxia in the Northern Gulf of Mexico
In addressing the state of the science, the book focuses on the strengths and limitations of the science in managing the Gulf hypoxia problem, including available data, models and model results and uncertainty.
Biogeochemistry of Estuaries
Biogeochemistry of Estuaries offers a comprehensive and interdisciplinary approach to understanding biogeochemical cycling in estuaries. Designed as a text for intermediate to advanced students, this book utilizes numerous illustrations and an extensive literature base to impart the current state-of-the-art knowledge in this field. While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries,Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. Estuaries, located at the interface between land and the coastal ocean are dynamic, highly productive systems that, in many cases, have been historically associated with development of many of the great centers of early human civilization. Consequentially, these systems have and continue to be highly impacted by anthropogenic inputs. This timely book takes the foundational basis of elemental cycling in estuarine and applies it to estuarine management issues. Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world.
Biogeochemistry of Gulf of Mexico Estuaries
The fisheries of the Gulf of Mexico make up the largest commercial fishery in the United States. But the ecology of the Gulf is in trouble: much of the Gulf is subject to critical problems with toxic microorganisms. This important book addresses the emergency, providing indispensable research findings and material on sedimentary processes, nutrient flows, carbon, and trace metal cycling. Time is of the essence in examining these problems; this book cuts to the heart of the matter, providing ecologists and biologists with the first coherent treatment of the subject.
