PSG Center for Molecular Medicine and Therapeutics was established in May 2009 under the aegis of the PSG Trust. It is located on the fourth floor of the new academic building at the PSG IMSR campus. The center fosters high end molecular research to understand the molecular mechanisms of various diseases.


Our vision is to build a healthier community by bringing active minds and rigorous research together in the crucible of collaborative clime.


We promote health by researching the intersection of fundamental and clinical, health and disease, cellular and community, evidence and practice, translation and treatment.


  • Integrity
  • Vision
  • Sharing
  • Perseverance
  • Lateral thinking
