Welcome to the Bio-Optoelectronic Group of the Department of Chemical Engineering of Institute of Chemical Technology Marathwada Campus led by Dr. Somen Mondal. Our research focuses on fundamental understanding of carrier dynamics across the biopolymer for insight the long range i.e, nm-scale to macroscopic electron and proton transfer which are essential for all development of Bio-Optoelectronic devices. Current research areas include:

​

  • Multiple exciton generation and dissociation dynamics for development of optoelectronic devices.

  • Ultrafast carrier dynamics in Quantum Dot based heterostructure (femtosecond transient absorption, Upconversation, TCSPC).

  • Light-induced interfacial electron transfer and proton transfer dynamics across the biopolymer.

  • Conductive biopolymer for protonic and electronic transistor.

  • Guest-host based applications in light harvesting system.

Hello! I am Dr. Somen Mondal, an Assistant Professor in Chemistry at ICT- Mumbai, Marathwada Campus. My current research interest is to explore the photophysics and carrier dynamics in Quantum Dot based heterostructure and also control the conductivity of protein based bio-materials for long-range electron and proton transport and applied towards the protonic and electronic transistor.

After successfully completing my undergraduate studies, I joined Indian Institute of Science Education and Research (IISER) Kolkata as a research fellow and during my research tenure I have tried to explore the excited state donor-acceptor properties of carbon nanoparticles in different confined environments as a versatile photosensitizer. One of the most interesting aspects of carbon dots is that they have very complex photo-physical behaviour that we still struggle to fully understand, such as the origin of the excitation wavelength dependent of the emission peak position. We use a myriad of steady-state and ultra-fast spectroscopy as well as electrochemical measurements for that purpose.

After my Ph.D., I joined at INST-Mohali, India, on 2017 for my first post-doctoral study. During this time, I worked on biexciton generation and dissociation dynamics in nanohybrids system. Before joining ICT, I was a postdoctoral researcher at Technion-IIT, Israel and the my main goal was to control the conductivity of protein based bio-materials for long-range electron and proton transport and applied towards the protonic and electronic transistor.
