Light into Life:
The Optical Architecture of the Leaf

November 5, 2025

5 to 6 p.m. | Online

Dive into the microworld of the leaf, where we encounter cells that trap, guide, and scatter light to enhance photosynthesis. In this talk, Aleca Borsuk, Ph.D., will present her work utilizing synchrotron 3D imaging, computer modeling, and laboratory experiments to investigate the optical architecture of the leaf—including what happens when leaf architecture goes awry. She’ll also share how this research could lead to an early-stage detection system for beech leaf disease, a foliar disease rapidly spreading through trees in the Northeastern US.

About the Speaker

Dr. Aleca Borsuk studies plant form and function across Earth’s diverse environments to understand how plant anatomy promotes light absorption and carbon assimilation, provides resilience to abiotic stress, and informs sustainable technologies that derive function from structure. Her approach uses recent innovations in three-dimensional imaging and computer modeling, combined with benchtop experiments, fieldwork, and greenhouse studies, to uncover the mechanistic basis of nature’s “living materials.”
