Research Interest:

My research interests lie in the interplay of physics, nanoscience and biology. I am particularly interested in developing new physical methods for quantitative imaging of nanoscale materials and biological specimens in three dimensions. I have played a major role in pioneering a three-dimensional imaging approach based upon the principle of using coherent diffraction in combination with a method of direct phase recovery called oversampling. I, together with my graduate students and postdocs, will continue to improve the spatial resolution of this imaging technique and pursue its applications in nanoscience and biology by using optical lasers, coherent X-rays and electrons.
