Research Interest

My group is involved in evaluating (a) the disease ameliorating role of several natural and synthetic compounds and of different nanocomposites, (b) Modulation of immunobiological responses in leishmanial infection.

     (a) Compounds from herbal and dietary sources, synthetic origins are being examined to

  • Study the anticancer activity using in vitro and in vivo murine models like melanoma, sarcoma, hepatocarcinoma and colorectal carcinoma 
  • Evaluate their efficacy to improve the disorders of diseases like leishmaniasis, allergic asthma, septicaemia, liver damage, obesity, type I and type II diabetes, and inflammatory bowel disease 
  • Assess anti-oxidant, anti-inflammatory potency of the active compounds
  • Explore the mechanistic aspects of beneficial effects of  the active compounds
  • Formulate different organ specific improved targeted delivery vehicle of the active compounds/drugs with or without controlled release property
  • Develop specific targeted therapies of bioactive compounds or drugs combined with specific targeted diagnostics (Theranostics) 
  • Biological evaluation of delivery efficacy of the nanocomposites in vitro and in vivo systems

    (b) Leishmanial infection

  • Evaluation of antileishmanial activity of some natural compounds and different nanocomposites
  • Highlights on several imunnobiological changes in leishmanial infection 


  •  Ph.D. on Immunology in 2002 from CSIR-IICB, Kolkata under Jadavpur University
  •  M.Sc. in Biochemistry in 1986 from University College of Science, Ballygunge of Calcutta University
