I am an Assistant Professor at the Research Institute for Sustainable Energy (RISE), TCG-CREST, Kolkata, specializing in Electrochemo-mechanics and interfaces/interphases in solid-state batteries (SSBs). My research integrates materials science, electrochemistry, and solid mechanics to address the fundamental challenges limiting next-generation energy storage systems.

With a Ph.D. in Materials Science from JNCASR (Chemistry and Physics of Materials Unit) under Prof. M. Eswaramoorthy, and postdoctoral experience in Germany at Justus Liebig University under Prof. Jürgen Janek, my work has focused on lithium metal anodes (LMA), the role of non-equilibrium defects on fast charging, microstructural engineering of solid electrolytes, lithium insertion-driven solid electrolyte fracture, contact mechanics, and electrochemical impedance spectroscopy (EIS) to enhance the performance of lithium metal-based SSBs.

Our work has been published in leading journals including Advanced Energy Materials, Advanced Functional Materials, Angewandte Chemie, and Matter, and includes a patent on high-surface-area ordered porous carbons (JNC-1/2). We actively mentor Ph.D. and postgraduate researchers and deliver invited talks on energy storage, SSB mechanics, and fast-charging technologies at various national and international forums.

At TCG-CREST, we are actively building state-of-the-art facilities for electrochemical characterization, in-situ spectroscopy/microscopy, and high-precision impedance analysis. Our current research focuses on interface stability, stress evolution, and charge-transfer kinetics in solid-solid systems, supported by competitive grants and collaborations with premier institutions across India.

Current areas of research include:

• Anode-free solid-state batteries
• Solid-solid interface kinetics
• Microstructural engineering of battery materials
• Ni-rich cathode (NCM 811 and beyond)
• Thermomechanical processing history of materials
• Electrochemical impedance spectroscopy (EIS)
• In-situ and operando AFM, XPS, and FIB-SEM
• Interface tribology
• Fracture mechanics, contact mechanics, and creep
• Finite element analysis (FEA)

With a strong emphasis on collaboration and mentorship, our lab serves as a platform for training the next generation of researchers committed to building a sustainable energy future.
