OverviewAI-generated summary

Narasimhan Rajaram is a professor at the University of Arkansas at Fayetteville. His research program focuses on the application of optical spectroscopy techniques, particularly diffuse reflectance spectroscopy, for biomedical applications. He has investigated the use of these methods for monitoring tumor response to various treatments, including immunotherapy and radiation, and for characterizing the tumor microenvironment. His work also extends to evaluating differences in optical properties between indolent and aggressive murine breast tumors and assessing heat stress-induced changes in biological tissues.

Rajaram has received significant federal funding for his research. He is the Principal Investigator (PI) on an NIH/National Institute of General Medical Sciences grant totaling $2,103,742 for the Arkansas Integrative Metabolic Research Center. Additionally, he is PI on an NIH/National Cancer Institute grant of $251,222 for the determination of functional and molecular biomarkers of treatment resistance with multimodal optical spectroscopy, and an NSF grant of $50,000 for developing a multimodal imaging platform to image bioenergetics in live tissue.

His scholarly contributions are reflected in a publication record of 125 papers, with an h-index of 24 and over 1,855 citations. Rajaram collaborates with researchers at the University of Arkansas at Fayetteville, including Joel Rodríguez Troncoso and Jesse D. Ivers, and at the University of Arkansas for Medical Sciences, including Samir V. Jenkins.
