Cecilia Diniz Behn is an assistant professor in the Department of Applied Mathematics and Statistics at Colorado School of Mines. She also holds an appointment as an adjoint assistant professor in the Department of Pediatrics at the University of Colorado School of Medicine. Her research focuses on multiscale mathematical modeling with applications in metabolism, sleep, and circadian rhythms. Recent work investigating sleep in early childhood was done in collaboration with colleagues Victoria Booth (University of Michigan) and Monique LeBourgeois (University of Colorado), and graduate student Kelsey Kalmbach (Colorado School of Mines). Diniz, Behn, and Booth have also developed a freely-available module to introduce high school students to mathematical modeling using a simpler model of the interaction between circadian and homeostatic processes. The module includes guided exploration of the model using an interactive, online simulator.
