Background

About Me

A bit more on who I am and what drives my work.

I'm a graduate student in Mechanical & Aerospace Engineering at Cornell University. I do my research at the Organic Robotics Lab under Prof. Robert Shepherd, where I am currently working on a new subsystem for the PSIB (Poly Sulfide Iodide Battery) fish project currently run by Douglas Palumbo. Nicknamed "RCADE," this project lies at the intersection of heat transfer and acoustics to improve the capabilities of this biomimetic soft-robotic fish.

Before graduate school I completed my B.S.E. at Case Western Reserve University in Cleveland, Ohio. There I studied under Prof. Chase Cao to develop new actuator designs that implemented liquid dielectric elastomers (Peano-HASEL actuators) to create biomimetic and rotational motion. I also studied under Prof. Angela Dixon to create the Modular Microfluidic Incubator that allowed nose-on-chip devices to be stored in safe environments while nasal deposition experiments took place.

Outside of research I spend time playing Dungeons and Dragons, weightlifting, and playing indie video games with friends. I am a Hefeweizen lover and a cilantro hater. I love the outdoors and enjoy hiking and camping when I find the time off to do so. Most of all I love my friends and I am always willing to try something new with someone at my side.

I'm currently applying to Ph.D. programs for Fall 2027 and open to research collaborations and internships in acoustic engineering, embodied energy, and soft robotics.
