The Environmental Science and Engineering department is pleased to announce that Dr. Smruthi Karthikeyan will join Caltech in January 2023 as an assistant professor in the Division of Engineering and Applied Science. Dr. Karthikeyan is currently a postdoctoral research scholar at the University of California San Diego where she is developing techniques for studying microbial community dynamics in complex ecosystems. She obtained her PhD in Environmental Engineering with a minor in Microbiology and Microbial Ecology from Georgia Institute of Technology in 2020. Her research interests lie at the interface of microbial ecology, computational biology and engineering. She builds predictive models that integrate physicochemical and transport data with multi-omic (DNA, RNA and metabolome-level) data to make accurate predictions of microbial community responses to environmental perturbations.
