Beaudry's research is in algebraic topology, homotopy theory and their applications. Her expertise is the study of chromatic homotopy theory (CHT) using techniques from equivariant homotopy theory (EHT). CHT harnesses the algebraic geometry of formal groups to organize information and streamline computations of the stable homotopy groups of spheres. In this context, Beaudry studies transchromatic phenomena and duality. In particular, Beaudry uses and develops techniques in EHT to answer questions in CHT. Beaudry's research also explores more general questions in EHT, beyond the scope of CHT. Finally, Beaudry also works on applications of homotopy theory to the classification of phases of matter in physics. This research is part of a crossdisciplinary project that includes faculty, students and postdocs from the Department of Mathematics and the Department of Physics at CU.
