Geomicrobiology, Assistant Professor, Geology & SREL

My research focuses on exploring life in extreme and unexplored environments with a broader goal of understanding the origin of life, microbial adaptation/evolution, and extraterrestrial life. My research uses multi-omics approaches and machine learning-based models to understand the role of microbes in the Earth system.

My current research activities include looking at anthropogenic impacts on biogeochemical cycles. We are also developing bioinformatics tools and streamlined pipelines for data mining and extracting information from sequence-based data. Some of the research themes that my lab is going to focus on are

  1. Microbial community function in extreme environments
  2. Role of viruses and eukaryotic microorganisms in ecosystem function and service
  3. Astrobiology
  4. Role of microbes in fate and transport of contaminants
