Professor Sasha Cai Lesher-Pérez joined the Chemical Engineering faculty at the University of Michigan, as an Assistant Professor in August, 2022. Leveraging his interdisciplinary background in microfluidics, biomaterials, tissue engineering, he leads the team to engineer in vitro models, particularly microphysiological models. Currently one of Professor Lesher-Pérez’s major interests is trying to understand how stress in our lives impacts human health. Particularly he is interested in how manifestations of stress disrupt the levels as well as the biological rhythms of different biomolecules in our bodies (e.g., hormones) and how misaligned biorhythms promote disease. In his free time, Professor Lesher-Pérez enjoys playing with his two kids and two dogs, watching and playing soccer, cooking, gardening and is hoping to get back into rock climbing!

High School Researchers

Tasneem Sunbulli


International Academy Okma, Class of 2025

Tasneem is working to establish a technique to use stickers as molds for microfluidic oscillators using low-cost off the shelf xerography-systems to generate molds. Because of the size limitation of low-cost xerography-systems, she is working to establish larger scale units to verify fabrication capabilities and the corresponding function of her oscillators. The goal of her project is to assess the feasibility of these tools and techniques in a more accessible and adoptable format.  In her free time she likes to figure skate, run, and paint.
