Summary
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, small molecules). 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 from droplets with microfluidics and acoustic levitation and tuning the triggered release of encapsulated materials through capsule microstructure design. I aim to not only address open, fundamental questions within the field of soft matter engineering but deliver translatable solutions to industry and society.
