Jonathan Beardsley

My research interests are in category theory, algebraic topology, and homotopy theory. I am specifically interested in using homotopical or “derived” algebra, in the form of operads, spectra, and infinity categories, to understand and classify structures that naturally arise in geometry and topology. Some geometric structures that I have specifically studied in previous work or am currently interested in include: cohomological invariants of topological spaces, the stable homotopy groups of spheres, the relationships between cobordism rings as the structure group is varied, A-infinity categories.

Diana Moss

My research agenda has transitioned from understanding how children make sense of mathematics in classroom settings to investigating pre-service teachers’ learning in mathematics methods courses and mathematics content courses. This transition occurred because I wanted to do research that would make a difference in my own teaching practice. At my first milestone and dissertation, I learned to study children’s learning of mathematics, specifically algebra, in a classroom setting. My second milestone was my third-year review and reappointment at Appalachian State University where I transitioned to learning to study pre-service teachers’ learning of mathematics. My third milestone occurred when I became an assistant professor at Utah State University and reframed my research to study pre-service teachers’ learning of mathematics and methods. My fourth milestone occurred when I became a teaching assistant professor at University of Nevada, Reno in the midst of the pandemic and focused on teaching mathematics content courses in an online synchronous setting and face-to-face setting. I have actively pursued practitioner research with the intention of “providing insights into teaching in an effort to make change” (Dana & Yendol-Hoppey, 2014, p. 9). Since 2018, I have been involved in research projects to help me engage in reflective practice and bring about positive change in my teaching. The projects are separate in nature, but all strive to connect my teaching philosophy, the course learning goals, teaching activity, and evidence of student learning. The purpose of each project is to analyze and transform teaching to create new learning experiences that focus on conceptual understanding based on meaningful reflections on teaching.

My research interest lies in applications of dynamical systems, more specifically, the study of nonlinear ODEs to model complex systems. Of particular interest is the Lorenz system, well-known for the so-called “butterfly effect”. Broadly, I am open to new ideas for applying dynamical systems to model real world scenarios.

My PhD project was concerned with deriving and exploring chaotic properties of new high-dimensional extensions of the Lorenz system, viewed as closer approximations of the Boussinesq fluid model for Rayleigh-Benard convection. Beyond the initial motivation for considering additional physical contexts under specific scenarios such as the presence of vertical gradient in scalar concentrations as in atmospheric aerosols or ocean water salinity, this project evolved into a quest to answer more fundamental questions about the chaotic nature of weather and fluid systems, leading to the derivation of a generalized high-dimensional Lorenz systems capable of furnishing an ODE system that represents a fluid system with arbitrarily high harmonic orders. Some interesting phenomena discovered along the way include a novel type of chaotic attractor, coexisting attractors, and synchronization of chaos, which led to some immediate applications in different fields such as image encryption technology and data assimilation in the context of numerical weather prediction. My ongoing research explores how different network configurations could change the synchronization properties, with certain configurations more prone to rare catastrophic events than others.

As a member of the Mathematics Public Health (MfPH) network at The Fields Institute, I had the opportunity to work on agent-based models for epidemic curves of a rapidly spreading infectious disease such as COVID-19. I focused on developing co-circulation models having two or more viral strains, utilizing both the traditional ODE-based approach (SIR) and the agent-based modeling (ABM) approach. My ongoing research in this area is focused on exploring how the infection network heterogeneity affects the epidemic curves and whether these effects can better be simulated using ABMs rather than ODEs.
