Current R&D/S&T Activities

Computational Chemistry, Biology and Informatics

Currently working in the broad area of research focuses on predictive toxicology, risk characterization, and assessment.

  • Developing innovative predictive approaches to address toxicological issues to fortify health and environmental safety by implementing the principles of 3Rs (Replacement, Reduction and, Refinement).
  • Understanding interactions and predicting the toxicity of biological systems and toxicological pathways using multi-resolution computational approaches.
      • Cheminformatics approaches for toxicity prediction and developing toxicology databases & tools for toxicology data analytics and dissemination.
      • Translational bioinformatics and toxicogenomic for understanding adverse outcome pathway/toxicity and biomarker discovery.
      • Developing In silico platform for safety/toxicity testing of chemicals, APIs, and drugs.
      • Toxicological database development and dissemination.
  • Providing services on computational predictive toxicology to the industries.
  • Fostering translation research and technology development to support entrepreneurship, startups and industries.
