Ayanjeet Ghosh

Dr. Ghosh is an Assistant Professor in the Department of Chemistry and Biochemistry. He is focused on bridging the gap between spectroscopy and imaging,  and exploring chemical contrast in biomedical imaging through spectral signatures of molecular assemblies. Seeing is believing, and Dr. Ghosh spends most of his time figuring out how to ‘see’ the chemistry of tissues and biomolecular aggregates. Current research in Dr. Ghosh’s lab (http://irislab.ua.edu) is funded through NSF and NIH R35 MIRA awards.

Research Interests

The central premise of Dr. Ghosh’s research is to employ infrared spectroscopy to provide chemical contrast in optical and atomic force microscopy. Research in Dr. Ghosh’s group seeks to extend the unique capabilities of infrared spectroscopy towards molecular imaging and push the boundaries of existing technology through development and application of infrared microscopies towards problems of major societal importance, such as characterization of amyloid aggregates in neurodegenerative diseases like Alzheimer’s disease.
