Roberto Zenit is the El Jefe (PI) of the lab. He is a full professor and Royce Family Professor of Teaching Excellence in Engineering at Brown University. He did his undergraduate in Mechanical Engineering at UNAM, Masters and PhD in Mechanical Engineering at Caltech, Postdoctoral training in Chemical Engineering at Cornell University, and then joined the faculty at UNAM in 1999.

He spends most of his time watching professional badminton and squash matches, playing competitive badminton with his students, and complaining about not eating enough cookies.




Madeline Federle is a 5th-year PhD student. She obtained her undergraduate degree from George Washington University in Mechanical Engineering. At Brown, she studies the interaction of a droplet and a bubble.

She loves space, bubbles, trying new foods, and playing with her fluffy dog (Comet).






Mithun Ravisankar is a 4th year PhD student. He did his undergraduate studies in Mechanical Engineering at Anna University, India. He obtained his Masters degree in Fluids and Thermal Sciences at Brown University, where he studied the bubble-bubble interaction in viscoelastic fluids. For his PhD, he studies the turbulence induced by the bubbles in viscoelastic fluids.

He never says no to ice creams.





Philip John Gaudio is a 3rd year PhD student from Connecticut who received his Bachelor’s and Master’s from the University of Hartford studying acoustical engineering and music, heat transfer, and fluid systems. He was an engineer at General Dynamics Electric Boat working on data acquisition aboard nuclear submarines. PJ is an experimentalist and studies microfluidics and small-scale fluid flow.

When not in the lab, he enjoys listening to jazz and electronic music, avoiding gluten, and working on cars.





Avery Trevino is a 3rd year PhD student. He earned his bachelor’s degree in mechanical engineering, with an emphasis in applied math and physics, from UC Berkeley. He did undergraduate research at Lawrence Berkeley National Laboratory studying stochastic mesoscale systems and computational fluid dynamics. At Brown, he conducts research in biological flows. Avery was born and raised in the San Francisco Bay Area.

Outside of his academics, he enjoys reading about art and history as well as watching stand-up comedy. He also loves to play golf, and more recently, badminton, conforming to group standards.
