Research in my group focusses on two exciting frontiers of science.
Silicon nanostructures for next-generation photovoltaics. We are synthesizing Si quantum dots (QD) with different passivants/ligands and studying their electronic and optical properties for insights into the subsequent design of new photovoltaic materials. We are also working on a template-based approach to synthesizing quantum confined silicon nanowire arrays that are oriented perpendicular to a (non)conductive substrate. These projects are supported by the NSF Renewable Energy Materials Research Science and Engineering Center which consists of a team of highly interactive scientists and engineers from CSM and the National Renewable Energy Laboratory.
Development of new analytical instrumentation, methodologies, and metrologies geared towards separating and characterizing nano-size analytes is urgently needed and represents a new frontier in analytical chemistry. My research program aims to establish a fundamental understanding of transport mechanisms leading to the successful separation of nanometer-sized analytes, use this understanding to develop the field-flow fractionation (FFF) family of separation techniques, and apply the developed technologies to high impact problems. Our research has been highlighted in C& E News and American Laboratory and was the subject of a feature article and issue cover of Analytical Chemistry.
