PhD Position

Posted on : 16/10/2023

Supervisor: Dr. Hare Krishna Mohanta

Topic: Development of Machine Learning and Molecular Simulations Driven Smart Gas Sensors for Toxic Gases

Brief Description of the topic:

There are several pollutant gases that are harmful to human beings and need to be detected. The high-performance sensing materials to be used in gas detection will be identified using molecular simulations, including molecular dynamics simulations and grand canonical Monte Carlo simulations. Machine learning techniques will be used to develop smart gas sensors. Molecular simulations and machine learning techniques together will help to design highly selective and sensitive smart gas sensors to be operated at room temperature.

Essential Minimum Qualification:

The candidate must be a graduate (B.E./BTech.)/post graduate (M.E./MTech.) in Chemical Engineering or allied disciplines or MSc in Physics/Chemistry/Material Sciences/Nanotechnology with at least 60% marks.

Desired Qualification:

Knowledge of programming languages like MATLAB, python, C/C++ will be helpful but not essential. Candidates should be willing to learn new modeling and simulation methods or computational skills.
