Other Scholarly Activities:

  • Mentors at least two undergraduate research students a year during the regular semesters.
  • Motivates both Chemistry & Biology students to apply for various summer internships. Every year, one or two students have been successful in getting NSF-REU fellowship.
  • Most of the research are being performed with a few BCU students during the summer in collaboration with FSU Chemistry faculty and so students have an opportunity to learn efficient techniques at FSU.
  • Reviews a number of research papers from Journal of Organic Chemistry (ACS), Theoretical Computational Chemistry (Elsevier), Canadian Journal of Chemistry, Ethiyopean Journal of Chemistry, Polyhedron etc.
  • Reviews a number of Ph.D. thesis which mostly comes from Universities in India.
