I am a research associate within the Polymers & Microfluidics group headed by Professor João T. Cabral. My research focuses on the spontaneous and stimulated assemblies of soft materials, their thermodynamic and non-equilibrium properties and response to external perturbations (flow, temperature, pH, solvents). My research spans multiple length scales; probing conformation of polymers, or shape of surfactant aggregates and mesophases, with small angle neutron scattering (SANS) as well as fabricating micron-scale polymer capsules with microfluidics and tuning the triggered release of encapsulated materials through design of capsule microstructure. I aim to not only address open, fundamental questions within the field of soft matter engineering but deliver translatable solutions to industries and ultimately society.

teaching & Outreach

Outside of the laboratory and office, I have spent 3 years working as a Graduate Teaching Assistant (GTA) within the chemical engineering department and am part of the Royal Society of Chemistry (RSC) local section committee, organising chemistry based events for the general public, students (secondary-university) and RSC members within London. I was heavily involved in the conception and production of "The Chemistry Communicators' Challenge" - a London-based science communication event aimed at bolstering student CVs and re-engaging chemists with the subject (
