Prof. Qinghua XU http://staff.science.nus.edu.sg/~chmxqh/Homeqxu.html Research Areas: Materials Physics and Chemistry/Biophysics/Optical Spectroscopy The research in our group mainly focuses on understanding the structure-dynamics-function relationship in low-dimensional materials, biological materials as well as fundamental chemical processes, using various novel optical spectroscopy and imaging techniques. Current research interests include conjugated polymers and oligomers, nanocrystalline materials, and DNA. Various state-of-the-art temporally and spatially resolved spectroscopic methods (including single nanoparticle spectroscopy and imaging) are being used or under development for these studies.
