My research focuses on biogeochemistry and non-traditional isotopes, and their application to solve problems relevant to earth system sciences and environmental studies.

My research focuses on biogeochemistry and non-traditional isotopes, and their application to solve problems relevant to earth system sciences and environmental studies. Specifically, I am interested in the stable isotope systems of alkaline earth metals (e.g., Ca, Mg, Sr) and redox-sensitive elements, and how these new isotope tracers can be used to further constrain: (1) the isotope evolution of seawater over geologic time, (2) diagenetic processes in marine carbonates, (3) material cycling in the Earth’s outer shell, and (4) paleo-environmental conditions and depositional settings in large sedimentary basins (i.e., Paleozoic and Proterozoic basins in Europe and Australia).

In 2018, I have established 'Metal Isotope Group' (MIG) whose primary research focus is on stable and radiogenic isotope systems of selected metals, and their application to solve problems relevant to earth system evolution studies, geochronology, metallogenesis and environmental issues. For more details on specific research projects, collaborators, and analytical facilities see also the link below for the MIG webpage:

Geochemistry II (Semester 2) - This course focuses on the chemistry of the natural world and the chemical evolution of the Earth and other planets over geological time. It covers practical and theoretical geochemistry, with an emphasis on how chemical principles are used to study problems relevant to Earth and Environmental Sciences 

Earth System History III (Semester 2) - This course studies the fundamental geological and biological processes comprising the Earth System. It focuses on the interactions between the biosphere and the geosphere as the Earth System evolved as recorded in the geochemical and sedimentary record.

Planet Earth I (Semester 2) - This course provides a global perspective of Planet Earth and the dynamic processes that have modified it over its 4 billion-year history. We explore Earth's place in space and time and examine the operation of its internal chemical and physical processes. Fundamental concepts are developed: the formation and structure of the Earth; the driving forces of plate tectonics and continental drift; earthquakes and volcanoes, the formation and identification of geological materials, mountain building and rock deformation; the development of the geologic timescale.
