We work with Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS) to design an updated version of their Jaipur Foot, which is the most widely distributed prosthetic foot in the world. The original Jaipur Foot’s success was due to its lifelike look, flexibility, and extreme durability. We aim to create a new version of the foot that is much lighter, can be mass-manufactured, meets international testing standards, is compatible with other prosthetic equipment, and matches the durability of the current foot. Using a novel prosthetic foot design objective called the Lower Leg Trajectory Error (LLTE) we are optimizing the compliance and geometry of our prosthetic foot to deliver lifelike gait mechanics using low-cost materials.

We developed a method to vizualise a hydrodynamic phenomenon. The reflection of an object can be distorted by undulations of the reflector, be it a funhouse mirror or a fluid surface. Here, we used this phenomenon to visualize micrometric surface waves generated as a millimetric droplet bounces on the surface of a vibrating fluid bath. This system, discovered a decade ago by Couder et al., is of current interest as a hydrodynamic quantum analog; specifically, the walking droplets exhibit several features reminiscent of quantum particles.
I explored a strongly non-linear behavior of a soap film undergoing large-amplitude harmonic oscillations in the low frequency range. In such a film, liquid is re-distributed towards its center and the large-amplitude modes lead to the ejection of bubbles of the size of the main wave length from the film. I developed a numerical model and designed an experimental setup to characterize the phenomenon.
We explored the hydodynamic instability of a viscous fluid on a rotating cylinder. Our power law model described the behavior at steady state of a the viscous fluid rotating at low speed on a cylinder. This phenomenon happens for example when you are scooping honey with a spoon. Honey flows down from the spoon and you can "catch" it by rotating the spoon. We then explored some instable behaviors of this hydrodynamic system at higher rotational speeds.
This project was conducted in collaboration with Delair-Tech a drone company. The goal of the project was to optimize the flight plan of a long range drone to use as little energy as possible by taking into account the wind map, the ground topology and the mission requirements. We deveoloped a Java based software that reduced by 14% the energy consumption of this long range drone flights
