Ph. D. Candidate
Suleman Jalilahmad Ansari

I am a dedicated researcher specializing in atomistic and coarse-grained molecular dynamics simulations, with research experience in biopolymers, nanoporous membranes, ion transport in electrolytes, and the mechanical properties of 2D nanosheets. My studies cover a broad spectrum, including the dynamics of pectin in saltwater for potential applications in flexible hydrogel electrolytes and saline water treatment (published in J. Mol. Liq. 2024). Another focus is on molecular mechanisms in nanoporous starch-graphene membranes to optimize ion rejection and water transport (J. Mol. Model. 2024). My research extends to understanding ion transport mechanisms in biopolymer-containing solid electrolytes (Nanoscale 2024), and investigating deformation mechanisms in monolayers and bilayers of graphene and h-BN nanosheets. Through these endeavors, I contribute valuable insights for designing innovative materials with applications spanning diverse industries.
Ph. D. Candidate
Sipra Mohapatra

Joining IIT Jodhpur's Ph.D. program in July 2019 under Dr. Santosh Mogurampelly, I bring a passion for unraveling the intricacies of ion transport mechanisms in polymer electrolytes. My academic journey began with an M.Sc. in Physics from Berhampur University, Odisha. Specializing in molecular dynamics simulations, I occasionally incorporate quantum mechanical calculations to refine interaction potential parameters. My research focuses on achieving a fundamental understanding of ion transport at the molecular level, exploring the dynamic interplay in ionic liquids, electrode-electrolyte interfaces, and polymerized ionic liquid systems. Beyond my core research, I have made significant contributions to several collaborative projects, resulting in publications in esteemed journals like Nanoscale, J. Chem. Phy., J. Mol. Liq., and Food Chem. As a member of the PEMG group, I find fulfilment in mentoring fellow researchers, contributing to a collaborative and innovative academic environment.
Ph. D. Candidate
Hema Teherpuria

My work primarily centers on soft matter physics, where I explore topics such as ion transport in battery electrolytes and the influence of patterned substrates on phase-separating binary mixtures through the application of molecular dynamics simulations. MD simulations play a key role in elucidating ion transport at the microscopic level in battery electrolytes because they provide insight into how ions behave in the electrolyte solution. Understanding these phenomena at the molecular level is vital for various applications, including materials design. I am working on the mechanisms of ion transport in different classes of polymer electrolytes including biocompatible and concentrated Li-ion battery electrolytes (Nanoscale 2024 and arXiv:2401.11182). I also focus on understanding the effect of the initial concentration gradient across the film in the phase separation of binary mixtures.
Ph. D. Candidate
Sapta Sindhu Paul Chowdhury

Exploring the mysteries of physics while unraveling the complexities of thermal transport in 2D materials has undeniably fueled my curiosity. My research covers novel insights into thermal conductivity in planar and buckled 2D materials such as graphene, h-BN, silicene, and germanene. To this end, I employ quantum mechanical calculations to develop interlayer interaction potentials, followed by classical MD simulations. My recent work resolved an unusual high thermal conducting behavior of the bilayer silicene (Phys. Rev. B. 2024). In germanene monolayer, we found an anomalous transition in thermal conductivity with temperature. I also work on ionic conductivity (Nanoscale 2024, arXiv:2401.11182) and magnetic proximity effects (Phys. Chem. Chem. Phys. 2019). My enthusiasm for programming has driven the development of several analysis tools for my research, including the PEMG group's website.
