Career/Teaching

The central theme of my research program involves the use of geochemical proxies (stable isotopes and trace/minor elements) to understand past and present biogeochemical cycles as well as paleo-climatological and paleo-environmental conditions. I focus on the use of biological carbonates as environmental/climatic record keepers, a field known as sclerochronology (analogous to dendrochronology). More precisely, I study how well skeletal chemistry records the environment. All proxies have their own limitations, and one of the main drawbacks in using a biologic carbonate is that the biology of the organism may interfere with equilibrium reactions in the skeleton. Understanding these 'vital effects' is part of my specialty.I am an Assistant Professor of Geology at Union College where I teach Stable Isotopes in Environmental Science, Restless Oceans, The Earth and Life Through Time and Biogeochemistry.

The core of my teaching philosophy revolves around actively including students in research and developing their critical thinking. I achieve this through exposing students to scientific peer-reviewed papers, the peer-review process, class discussion on controversial topics in environmental sciences (both intro and upper level classes) and having students conduct their own research project (upper level classes). I have taken several students to regional and national meetings for them to present their research. I also strongly feel that a field component should be incorporated into all classes. I find that field trips can make learning fun, and help me connect with the students as well as creating a ‘community’ feeling in the class and department.

 

 

      

 

Research

Essentially all we know about past climates and ecosystems is derived from either chemical or physical proxy records stored in solid structures such as tree-rings, ice-cores, or carbonate skeletons. Understanding how precisely these proxies record their environment is of paramount importance to understanding global climate change. It is well known that each proxy has its benefits and drawbacks. For example, ice cores can only be obtained from limited locals; trees only provide terrestrial records. Biological carbonates, however, are found from the poles to the tropics and from shallow freshwater and marine systems to the deep oceans. My research focuses on the use of biological carbonates as environmental/climatic record keepers, a field known as sclerochronology (analogous to dendrochronology). More precisely, I study how well skeletal chemistry records the environment (or sclerochemistry, a term a colleague and I recently proposed [Grocke and Gillikin, 2008]). One of the main drawbacks in using a biologic carbonate is that the biology of the organism may interfere with equilibrium reactions in the skeleton. Understanding these ‘vital effects’ is my specialty. I have worked on trace elements such as Sr/Ca, Ba/Ca, Mg/Ca, and Pb/Ca as well as stable isotopes (see publications bellow). My current projects include estuarine and freshwater biogeochemistry, freshwater mussel shell geochemistry, isotope chemostratigraphy and chemical dendrochronology.
