Biography

I am from the state of West Bengal, from a town called Rahara, which is currently a part of “Greater Kolkata”. I joined Prof. Prasad’s Research group as a Ph.D. student in July – 2014. My research interest is to study the photoinduced electron transfer dynamics of (i) conjugated donor-pi-acceptor fluorophores and (ii) graphene quantum dots, using transient absorption spectroscopy.

Education

  • M. Sc in Chemistry , University of Hyderabad, Hyderabad, India 2012-2014.
  • B. Sc in Chemistry, University of Calcutta, Calcutta, India 2009-2012.

Research Interests

  • Photoinduced electron transfer dynamics of (i) conjugated donor-pi-acceptor fluorophores and (ii) graphene quantum dots, using transient absorption spectroscopy.
