个人简介

Professor Tran received his B.S. degree from Kumamoto University in Japan and his Ph. D. from Texas A & M University. He joined Brookhaven National Laboratory as a Staff Scientist in 1982 after spending two years doing post doctoral research at the Royal Institution of Great Britain. He has been on the faculty at Marquette University since 1986.

Analytical Chemistry

Our research involves the development and applications of novel instruments and methods for fundamental studies in analytical chemistry and material science. The overall objective of these studies is to gain insight into complex chemical and biochemical systems and processes as well as to develop novel biomaterials and high performance chemical and biosensors. We are approaching this goal from many different directions. Selected ongoing projects are: Development of an acousto-optic tunable filter (AOTF) as the "New Generation Monochromator" that has fast scanning speed, high throughput and wide spectral tuning range, and use it to develop novel instruments which otherwise are not possible. Synergistically combining spectroscopy and imaging to develop a novel near-infrared multispectral imaging (NIR-MSI) instrument and microscope which can rapidly (milliseconds) records tens of thousands of spectra at tens of thousands of different positions within a sample with spatial resolution of ~10 microns and ~1 micron, respectively. Investigate biomedical application of the NIR-MSI instrument and microscope including their use for noninvasive detection of cancer. Explore the use of the NIR-MSI miscrope to visualize single nano- and microparticles in order to characterize them and to monitor changes induced by either light,heatl or chemicals. Extend applications of the mutispectral imaging instrument to material science, namely, using the imaging instruments to determine chemical inhomogeneity, and correlation between the inhomogeneity and physical properties of a variety of materials including biopolymers, sol-gels and nanocomposite materials, Synthesis and characterization, of novel room temperature ionic liquids, and exploit their unique properties to develop novel methods which otherwise are not possible, e.g., novel chiral selector for capillary electrophoresis (CE), novel stationary phases (SPs) for GC and HPLC. Development of green and recyclable method to synthesize high performance, biocompatible and biodegradable supramolecular composite materials from biopolymers (e.g., cellulose, chitosan, cyclodextrins) and exploit their biomedical, bioanalytical and analytical applications including removal of pollutants, toxins and bacterias.
