The central premise of Dr. Ghosh’s research is to employ infrared spectroscopy as a means to provide chemical contrast in optical and atomic force microscopy. Research in Dr. Ghosh’s group will seek to extend the unique capabilities of infrared spectroscopy towards molecular imaging, and push the boundaries of existing technology through development and application of novel infrared microscopies towards problems of major societal importance, such as cancer diagnostics and design of better solar cell materials.
