  • Ph.D. , , University of Delhi
  • M.Sc , , Gauhati University

Dr Mahaswetta Saikia , Associate Professor , Department of Botany, Hansraj College, University of Delhi has done her M. Sc (Botany) from Gauhati University, Assam and completed her Doctoral Research on digestive physiology of Antheraea assamensis from the Department of Botany, University of Delhi under the Guidance of Professor Sudeshna Mazumdar-Leighton. For a brief period, she has also worked as a post-doctoral fellow at the National Institute of Immunology (NII), New Delhi. Dr Saikia has published her research work in Journals of international repute. In 2012, one of her paper in Insect Molecular Biology was among the two papers selected from Asian region, which demonstrated the strength and scope of the research on insect molecular biology emanating from Asia. Her areas of research interest are:

  • Insect- Plant Interactions
  • Structure function and evolution of gene families
  • Molecular strategies for pest control in economically important plants/ food crops

Dr Saikia is also actively engaged in various administrative responsibilities in the college and just completed her term as Superintendent, Practical Exam, Deptt. of Botany in August 2023. She has also undergone a one week  training on Hydroponics at IARI , Pusa.  Presently she is teaching the following course at the undergraduate level (last two semesters):

  1. Biofertilizer, G.E
  2. Cell and Molecular Biology, Lifescience Semester IV
  3. Basic Laboratory Techniques in Plant Biology, Semester I
  4. Microbiology and Plant Microbe Interactions, Semester II
