Sourabh Dhingra, PhD

About Me

Sourabh joined Cramer lab in June after finishing his PhD at Northern Illinois University. During his PhD, he gained extensive knowledge about molecular biology of Aspergillus spp. Specifically, I studied regulation of secondary metabolism in Aspergillus spp.

Currently, he is investigating the virulence attributes of A. fumigatus. He is interested in the effects of the infection site microenvironment, particularly to changes in oxygen availability, on fungal and host metabolism and how these effects determine the outcome of infection. As hypoxia adaptation has been shown to contribute to the virulence of A. fumigatus, he is interested in testing the hypothesis whether remediation of hypoxia at the infection site can reduce fungal virulence and improve the efficacy of existing antifungal drugs. Along these lines, he is pursuing the identification of transcriptional networks that mediate A. fumigatus adaptation to hypoxia.
