Educational background:
2010 – 2014: B.Tech in Chemical Engineering, National Institute of Technology Durgapur, India
2014 – 2016: M.Tech in Chemical Engineering, Indian Institute of Technology Kharagpur, India
2016 – 2020: PhD, Department of Chemical Engineering, Imperial College London, UK
Research experiences:
PhD thesis titled “Micromechanics of particle-coated bubbles: deformation from quasistatic to millisecond timescales” , as part of the ExtreFlow Project funded by the European Union’s Horizon 2020 Excellent Research program. Main supervisor: Dr. Valeria Garbin; Co-supervisor: Prof. Paul F. Luckham.
Research involved experimental investigations into the dynamics of complex interfaces under extreme deformation, using bubbles as interfacial rheological probes. By observing the evolution of particle-coated bubbles, either undergoing volumetric oscillations in ultrasonic fields, or simply undergoing dissolution, insights were obtained into the micromechanical response of particle-coated interfaces over a broad range of time scales spanning from 104 to 10-4s.
2020 – 2021: Postdoc at Delft University of Technology, Netherlands
Postdoctoral Researcher in Dr. Valeria Garbin’s research group ‘Transport Phenomena in Soft and Biological Matter’, Department of Chemical Engineering.
Developed a model to describe the micromechanics operative in colloid monolayers, subjected to high-frequency areal oscillations. Extended the experimental protocols for ultrasound-induced oscillating bubble to probe the high-frequency rheology of bulk soft matter. Involved in project on investigating the microstructural features governing fracture of colloid monolayers using machine-learning.
2022 – present: Postdoc at École Normale Supérieure
Postdoctoral Researcher with Damien Baigl (ENS Paris) and Cécile Monteux (ESPCI) as advisors.
Objectives include developing microfluidic approaches to reconstitute interfacially active proteins, by acellular route, within emulsions and evaluate their viscoelastic properties, as function of gene expression, within the broader domain of synthetic biology.
