Dr. Subba Rao Chaganti recently joined CIGLR as an Assistant Research Scientist. Chaganti’s research focuses on understanding the structural and functional diversity of the microbial community (bacteria, archaea, and protists) and how they mutually interact within the aquatic, terrestrial and host associated environments, how they are influenced by biotic and abiotic mechanisms and how they are altered by aquatic invasive species and other anthropogenic inputs and its overall impact on the ecosystem process. To answer these questions his research shares a core set of interdisciplinary tools sourced from ecology, environmental biology, molecular genetics, and bioinformatics while viewing microbes as cellular components of the ecosystem body. As a part of CIGLR, he is working on projects distinguishing toxin-producing from non-toxin producing cyanobacterial blooms and improve short-term toxin forecasting by application of omics tools, identification of biotic and abiotic conditions that trigger the toxin genes of cyanobacteria, monitoring rare and aquatic invasive species using environmental DNA and its ecological impact, assessing lower food web dynamics and their importance to fisheries and mapping unknown trophic pathways from microbes to crustacean zooplankton.

  • Identification of biotic and abiotic conditions that trigger the toxin genes of cyanobacteria
  • Assessing lower food web dynamics and their importance to fisheries
  • Monitoring endangered and aquatic invasive species using environmental DNA
  • Role of microbes in host-parasite interactions
