I am a Ph.D. candidate in mechanical engineering at the University of Michigan. I conduct research under the guidance of Professor Jon Estrada in the Experimental Soft Mechanics Lab.

I am broadly interested in the continuum-scale modeling of solid materials and structures that undergo large deformation. In my ongoing projects, I am advancing the theoretical and computational bases of novel experiments to characterize soft polymers and hydrogels: (1) inertial micro-cavitation rheometry (IMR), which uses laser-induced cavitation to assess the viscoelastic properties of soft materials under ultra high strain rates (i.e., >106/s); and (2) magnetic resonance cartography (MR-u), which acquires 3D displacement fields and calibrate hyperelastic models via the virtual fields method.

My side passion is the history of science, mathematics, and engineering. I am the creator of the Twitter series #DailyMechanician, through which I hope to share bits and pieces of how the field has evolved, while putting faces to the names behind important equations and landmark papers.
