Professor Nathan Sniadecki's research is in the areas of cell biomechanics, mechanobiology, and bioMEMs. Specifically, his lab is developing micro- and nano-scale tools to understand the mechanical properties of cells. His lab uses arrays of flexible silicone posts to measure the contractile forces of cells, computational modeling to examine cell mechanics, and microfluidic devices to investigate the cardiovascular system. The long-term goals of his work are to understand the ways in which mechanics plays a role in tissue growth and cardiovascular disease and how cell mechanics can be used to improve human health through better diagnostic systems and improved tissue engineering. Professor Sniadecki is the CTO and co-founder of Stasys Medical Corporation and scientific advisor for Curi Bio and Micro Phone Lens.

How to do heart research during a pandemic
Researchers at the Institute for Stem Cell and Regenerative Medicine share how they’ve adapted space technology to understand how the heart can be injured by the coronavirus.
Rainbow reporters show heart cell proliferation
The research, co-led by ME professor Nate Sniadecki, could improve cell therapy for heart disease and other conditions.
Hearts in space
Mechanical engineering professor Nathan Sniadecki explains the research benefits of organ and tissue chips and why some — like the heart tissue chips developed in his lab — are sent into space.
