Madelyn I. Payne

About Me

I am a PhD Candidate in the Department of Materials Science and Engineering (MSE) at the University of California, Berkeley, under the guidance Prof. Andrew Minor and Prof. Mark Asta. My research focuses on understanding the deformation mechanisms in high entropy alloys via electron microscopy. I conduct both ex-situ and in-situ nanomechanical tests to characterize the deformation of alloys for extreme environments. My experiments include in-situ transmission electron microscopy (TEM) tensile experiments and post-mortem structural analysis with high-resolution TEM and four-dimensional scanning transmission electron microscopy (4D-STEM) measurements. Our results help us understand how various mechanisms work together to produce mechanical properties such as fracture toughness, ductility, and tensile strength, and allow us to predict alloy behavior under different stresses and conditions, ensuring safety and efficiency in applications such as jet turbines.

While at Berkeley, my work has been supported by the College of Engineering/Department of Materials Science and Engineering Fellowship and National Defense Science and Engineering Graduate (NDSEG) Fellowship. I keep connected with the greater graduate student community through my roles as the MSE Graduate Assembly delegate and department lead for the Anti-Racist Reading Groups. Off campus, I enjoy playing tennis, social dancing, and practicing Judo!
