Surface and Trace Chemical Analysis Group

Welcome

The Analytical Microscopy Group conducts research on the chemical and structural properties of matter by applying various ion and photon based microscopies whose resolution range from micrometers to nanometers; Researches the fundamental aspects of the excitation process, quantification, standards development, instrumental improvements, and data analysis challenges associated with these analytical methods; Conducts research on autoradiography and nuclear track methods; Conducts research in generation and size-calibration of particles; Develops and applies methods for the concentration, separation, and isotope measurement of trace atmospheric gases and particles; Researches fundamental aspects of trace detection of explosive and narcotic particles using ion mobility spectrometry; Applies analytical microscopy methods to problems in materials science, semiconductor technology, bioscience, environmental science, and homeland security.
