  • Graduate and Post-graduate level in subjects such as Biochemistry, Cell Biology and Molecular Biology
  • Ayurveda Dietetics
  • Communication in science


  • Fly model for early life malnutrition
  • Program management


  • Communication with local communities on food, health and Ayurveda

Current Interests:


  • MSc Life Sciences (Ayurveda Biology)
  • Developing Ayurveda Dietetics Program


  • Developing a Fly model for early life malnutrition.
  • Exploring the potential of neuropeptides and digestive enzymes as biomarkers of early life nutritional exposure.
  • Study the ability of dietary interventions to reverse early life malnutrition mediated reprogramming of metabolic and immune systems. Focus on nutraceuticals and Ayurveda-based herbs.


  • Engaging effectively with communities to improve public health nutrition outcomes especially for women of reproductive age and infants.
  • Policy issues on capacity building in science education, integrative healthcare and AYUSH-related topics.
