Welcome to the Marine Molecular Ecology and Physiology Lab

Marine Ecology is the study of marine organisms, their habitat, populations, and interactions among themselves as well as with their surrounding environment including abiotic (i.e. non-living physical and chemical factors) and biotic (living organisms) factors.

The recent advances in the molecular and physiological tools and techniques have enabled us to understand better how ecological processes work in the marine environment. The utilization of molecular methods such as PCR, real-time qPCR, Next gen seq (RNA-Seq, RAD Seq, de novo genome seq.. etc.) has been widely used in recent years to understand the physiological and adaptive response of marine organisms under varying environmental conditions. Similarly, application of molecular phylogenetics and population genomic approach has significantly increased in recent years to answer traditional ecological questions such as assessment of taxon diversity, identification, evolution and so and so on. The ecological questions which are answered using molecular methods come under the category of Molecular Ecology.

Physiological ecology is the sub-category of ecology where we study how biotic and abiotic factors act on the physiological characteristics of an organism and how the organism adapts to the dynamic environment.

We, in our lab, apply molecular and physiological tools and techniques  to investigate:

  • Physiological and Functional Diversity of Marine Organisms
  • Physiological and Adaptive Response of Marine Organisms to Climate Change in particular, Seaweeds and Climate Change
  • Ecology and Biology of Halotolerant microbes


  1. Recent work on metabolic response of seaweeds to ocean acidification is published in Science of the Total Environment (https://www.sciencedirect.com/science/article/pii/S0048969718322526?via%3Dihub).
  2. Congratulations Joji !! for best oral presentation in DBT sponsored National Symposium on the Application of Genomics and Proteomics in Aquaculture, Fisheries and Marine Biology.
  3. Congratulations Joji !! for best poster in ICWEEE conference. 
  4. Our recent work on Temperature stress response on M. rosenbergii larvae got accepted in Indian Journal of GeoMarine Science.. Congratulations Joji and Dr. Vinu!!
