During his Ph. D study, Oscar focused on binary collisions of wetted particles in the pendular regime. He developed a novel method using an electrified Newton’s cradle to measure the contact dynamics of two colliding wetted particles with a time resolution multiple orders of magnitude faster than current high speed imaging techniques. This novel method was coupled with numerical simulations to investigate a promising model which suggests that the interstitial liquid undergoes a glass transition.

At Columbia, Oscar uses both experimental and numerical techniques to investigate complex multiphase systems. He is particularly interested in experiments of highly unstable three-phase (gas/liquid/solid) multiphase flows, and the work we can do to improve our understanding and control of these systems.
