Niranjana Krishnan obtained her PhD in Toxicology from the Entomology department at Iowa State University. Working with advisors Drs. Steven Bradbury and Joel Coats, she assessed the risk of insecticide exposures on monarch butterflies. Prior to that, she obtained her Bachelor's degree in Microbiology from University of Mumbai and Master's degree in Biomedical Genetics from Vellore Institute of Technology, India.

Niranjana's current research interest is to apply in vivo, in vitro, and in silico techniques to estimate risk of chemical exposures on invertebrate species, including species of conservation concern. Techniques of interest include testing of whole organisms, generation of models to extrapolate toxic effects, development of adverse outcome pathways, assessment of toxicokinetic and toxicodynamic factors to elucidate differences in interspecies susceptibility, etc.
