Originally from India, where I obtained my B.Tech in Chemical Engineering at the National Institute of Technology Durgapur in 2014, followed by an M.Tech at the Indian Institute of Technology Kharagpur in 2016. I did my PhD in the United Kingdom, at Imperial College London until 2020. My PhD research was focused on understanding the interfacial mechanics of particle-coated bubbles undergoing deformation over sub-millisecond and quasi-static timescales. I am currently expanding on this work as a postdoctoral researcher.


I joined Valeria’s group at Imperial College London in 2016, and since then I have been involved with experimental investigations of the dynamics of colloidal monolayers under extreme deformation, using bubbles as interfacial probes. By observing the evolution of particle-coated bubbles, either undergoing volumetric oscillations in ultrasonic fields, or simply undergoing dissolution, we gain insights into the rheological response of complex interfaces over a broad range of time scales. In parallel, we also investigate the rheological response of bulk materials in presence of an oscillating bubble, driven by ultrasound.
