Research Interests

I strongly believe in the idea that 'There is no more neutrality in the world. You either have to be part of the solution, or you are going to be part of the problem.'  

My objective is to push the limits of Nanoscience and become part of the solution to real-world problems of the century to effect influential change. 

Our research work is focused on developing sensor array to detect the multiple Volatile Organic Compounds (VOCs) in breath for healthcare diagnostics with potential for miniaturization and facile integration in electronic circuits. Increasing effort is needed in the field of healthcare diagnostics to improve the early and convenient analyses of human health for screening at an early stage of diseases which will eventually improve the cure rate of diseases.

Thesis title - Hydrophobic Interface Analysis of Amyloid β (1-42) Peptide Plaque using Molecular Dynamics Simulation

Supervisor: Dr. Anurag Prakash Sunda

Focused on Hydrophobic interface analysis of Amyloid peptide plaque using Molecular Dynamics simulation. In Alzheimer’s disease, Amyloid peptide-protein fragments are formed in the brain and clump into plaques which destroy the neuron cells, memory cells, loss of brain function and ultimately fatal. We studied the various intermolecular and intramolecular interactions which lead to the formation of the hydrophobic core.
