In his teaching, Prof Panwar emphasizes concepts of interfacial phenomena, soft matter physics and diffusion in materials. Some courses taught are:
Undergraduate courses: Colloids and Interfacial Science, Kinetics of Processes
Postgraduate courses: Diffusion and Kinetics, Molecular Simulations of Materials
Prof Panwar’s research focusses on utilizing largescale molecular simulation methods to discover fundamental phenomena at the interface of biology and soft matter physics. He uses multiscale molecular simulation techniques and free energy calculation methods to understand how molecular interactions lead to diverse assemblies and phenomena in biology and materials science. In the area of biophysics, his research group explores selfassembly of peptides into amyloid fibrils in neurodegenerative diseases, nanoscale transport between the cell nucleus and cytoplasm and enzymatic processes. Based on the simulations, new pathways for amyloid formation were proposed, which have important implications on the understanding of neurodegenerative diseases. Such insight can accelerate development of novel inhibition and therapeutic strategies for neurodegenerative diseases. In the area of soft materials, his research activities include, examining the role of electrostatic effects in the selfassembly of hybrid nanomaterials and earlystage polymer dynamics in heterogeneous polymer crystallization.
