# Orit Peleg

Orit Peleg (born 1983) is an Israeli computer scientist, biophysicist and Associate Professor in the Computer Science Department and the BioFrontiers Institute at the University of Colorado Boulder in Boulder, CO. She is also an External Professor of the Santa Fe Institute. She is known for her work on collective behavior of insects and the biophysics of soft living systems, including honeybees and fireflies. Applications of her work range from human communication, smart-material design, and swarm robotics. She has won national and international awards and prizes, including a Sloan Research Fellowship in Physics in 2023, a National Science Foundation CAREER Award in 2022, a Cottrell Scholars Award in 2022 and being named a National Geographic Explorer in 2021.

## Education and academic career

Peleg completed her Bachelor's and Master's degrees in Physics and Computer Science at Bar-Ilan University in Ramat Gan, Israel in 2007. She received her PhD in 2012 from ETH Zurich, where she studied competitive interactions in biological systems. Her doctoral research considered the physics of biological nanopores. Peleg then moved to Harvard University, where she was a postdoctoral fellow in the Department of Chemistry and Chemical Biology and then the School of Engineering and Applied Sciences. There she worked on the evolution of protein interactions and the morphology of honeybee swarms.

## Research and career

In 2018, Peleg joined the faculty of the University of Colorado Boulder in the Computer Science Department and the BioFrontiers Institute. In 2019 she was appointed to the Santa Fe Institute. Her research considers how living organisms generate and interpret signals for the purpose of communication.

### Fireflies

Peleg revealed that fireflies synchronize their flashing and that there is a critical density that must be reached before the fireflies can get in rhythm with one another. This work was covered by popular news outlets, including National Geographic, NPR, Smithsonian Magazine, Harper's Magazine, and The New York Times.

### Honey bee communication

Peleg is interested in the communication of honey bees, which can aid the conservation of pollinating insects. She uncovered how swarms of honey bees communicate through scenting to create scent "maps" so that the swarm can locate the queen bee. Peleg demonstrated that honey bees collaborate in clusters to respond to mechanical forces when the swarm is shaken, and that honey bees collaborate to create air ventilation in congested nest cavities. This work was also covered in the popular media, including ABC News, Discover Magazine, and Forbes.
