Research Interests
Although I am Knowledgeable in most branches of Earth sciences, my main area of interest is Thermochronology; the use of radioactive isotopic systems to evaluate the thermal and mechanical history of rocks. I use fission-track analysis on different minerals, to determine the thermal and mechanical history of existing and long gone mountain ranges that formed as a result of extensional (rifted continental margins e.g. Red Sea and northern Atlantic margins) and compressional (e.g. Rocky Mountains) tectonics, rift basins along the eastern seaboard of the USA., and dating of meteorite impact events.
