Speaker: Orit Peleg (University of Colorado Boulder)Title: Emergent Spatiotemporal Patterns in Insect SwarmsAbstract:For the overwhelming majority of organisms, effective communication and coordination are critical in the quest to survive and reproduce. A better understanding of these processes can benefit from physics, mathematics, and computer science – via the application of concepts like energetic cost, compression (minimization of bits to represent information), and detectability (high signal-to-noise-ratio). My lab's goal is to formulate and test phenomenological theories about natural signal design principles and their emergent spatiotemporal patterns. To that end, we adopted insect swarms as a model system for identifying how organisms harness the dynamics of communication signals, perform spatiotemporal integration of these signals, and propagate those signals to neighboring organisms. In this talk, I will focus on two types of communication in insect swarms: visual communication, in which fireflies communicate over long distances using light signals, and chemical communication, in which bees serve as signal amplifiers to propagate pheromone-based information about the queen's location. Through a combination of behavioral assays and computational techniques, we develop and test model-driven hypotheses to gain a deeper understanding of these communication processes and contribute to the broader understanding of animal communication.

Brain-Body Music: Bridging Neuroscience, Physiology, and Human–Computer InteractionThis talk will present new directions in brain–body music research, situated within the broader field of human–computer interaction. I will share interactive systems and experimental studies from the Brain Music Lab that use brain and body signals—such as EEG, heart rate, and respiration—to create dynamic musical feedback. These systems serve as testbeds for embodied communication between humans and machines, and as tools for studying how music mediates empathy, attention, and social connection. Alongside the scientific investigations, I will highlight performances and installations that transform physiological data into sound, demonstrating how creative practice can advance HCI research while opening new avenues for musical expression.Bio: Grace Leslie is a researcher, composer, and flutist advancing the science and practice of music technology at the intersection of neuroscience and human–computer interaction. She is an Associate Professor at the University of Colorado Boulder (ATLAS Institute; College of Music), where she directs the Brain Music Lab.Her research investigates how music interfaces with brain and body, with a focus on sensorimotor synchronization, multisensory biofeedback, and inter-brain coupling. Through experiments and interactive systems, Leslie explores music as a medium for communication, empathy, and regulation. This work has been supported by the National Science Foundation, including a prestigious NSF CAREER Award, which supports her lab’s development of new brain–body music interfaces.Leslie’s publications span music cognition, human–computer interaction, and interactive system design, and her research has been featured in both scientific and artistic venues worldwide. Complementing this scholarship, her performances and installations transform EEG, heart, and breath signals into immersive sonic experiences, translating physiological states into sound.
