Excited to share our new paper in Nature Communications Physics offering insights for "Egg Drop" competitions and how technical language shapes learning outcomes by detailing what we mean when we say an egg is strong, stiff, or tough:
nature.com
Communications Physics - Common assumption dictates that an egg exhibits greater structural resistance when dropped on its end rather than on its side. To test this supposition, the authors perform...

We're excited to share our work exploring the nonlinear Eshelby inclusion problem for soft materials, revealing how growing spheroidal inclusions approach a non-spherical asymptotic shape under large deformations--the isomorphic limit:

In the late 1950s, Eshelby’s linear solutions for the deformation field inside an ellipsoidal inclusion and, subsequently, the infinite matrix in which it is em...

We’re excited to present our latest work explaining the spread in measurement of PDMS elastic properties. Explore our findings and see what they could mean for future applications of this versatile material. #SoftMatter #PDMS.
I'm pleased to share that the second paper of my PhD has been published in Soft Matter is now available online at If you'd like to see me present this, and the rest of my work from the @CohenMechGroup, I will be defending my thesis *this Wednesday*.

It's almost the start or the semester and that can only mean one thing: the @MIT_CEE FPOP Egg Drop Competition is back! Only one team's egg survived, but everyone learned lessons in strength, energy dissipation, and designing for intentional failure.

What does it mean for frontal polymerization (FP) to be thermo-chemo-mechanically coupled? In our latest article we elucidate how stress can quench the propagation of curing in FP reactions, demonstrating why solid mechanics is vital for FP future work

By merging growth formulations with a nonlinear poroelasticity theory (developed by Prof. @zhigangsuo's group), we show that the theory kinetically captures conventional phenomenological prescriptions for growth dependence on concentration of diffusing species and stress. (2/2).
