I am a recent graduate of Caltech’s Mechanical Engineering PhD program and am currently working as a postdoc in the department.
My thesis work with Prof. Chiara Daraio focused on developing systematic approaches to the design of shape-changing structures. This entailed studying how a structure’s global mechanical behaviors can be “programmed” by tuning geometric features at the micro/mesoscale, then using these concepts to create deployable devices and soft robots that change shape and locomote in response to environmental stimuli. In addition to my work at Caltech, I was a NASA Space Technology Research Fellow and spent two summers collaborating with researchers at the NASA Jet Propulsion Lab. Before moving to California for graduate school, I earned a B.Sc. in Mechanical Engineering at MIT.

There is a strong connection between a material’s microstructure and its macroscopic mechanical behaviors. With the emergence of advanced manufacturing techniques that allow engineers to tailor microstructures, we have seen the creation of materials that can be “programmed” to display desired functionalities. Examples of this include initially flat sheets that morph into target 3D geometries and soft robots that can locomote through their environment by using temperature-responsive materials that propel the robotic frame. My research studies the connection between the microstructure of materials and their macroscopic shape-morphing behaviors, with the aims of predicting how materials will deform due to applied loads or environmental stimuli and to design structured media that undergo target deformations. Achieving these aims opens doors to new applications in deployable space structures, architecture and soft robots that interact with their environments without carrying onboard batteries and controllers.
