Matthew J. Paszek
Smith School of Chemical and Biomolecular Engineering
Matthew began his scientific career as an undergraduate in the School of Chemical Engineering at Cornell University. Upon receiving his B.S. from Cornell, Matthew went on to pursue a Ph.D. in Bioengineering at the University of Pennsylvania under the mentorship of Professors Daniel Hammer and Valerie Weaver. There he conducted experimental and theoretical work that identified increased tissue stiffness and enhanced tumor cell contractility as key driving forces of cancer progression. Matthew then moved to the University of California, San Francisco under the mentorship of Valerie Weaver, where he began his work in glycobiology and developed Scanning Angle Interference Microscopy, a powerful tool for imaging live cells at the nanoscale. In 2013, Matthew returned to Cornell University as a Kavli Fellow under the mentorship of Professor’s Abraham Stroock and Claudia Fischbach, and worked on the development of high speed, custom optoelectronics for nanoscale cellular imaging. In the Spring of 2014, Matthew joined the Cornell faculty as an Assistant Professor in the School of Chemical and Biomolecular Engineering. His current researches focuses on how chemistry and mechanics are coupled in living systems.
The hardware for intracellular signal transduction consists of thousands of membrane receptors and signaling molecules carefully arranged throughout the cell. Notably, the cell expends the majority of its energy maintaining its biomolecules in spatial arrangements outside of thermodynamic equilibrium. The Paszek group investigates how signaling patterns emerge from these spatial arrangements and what role mechanical forces and biophysical interactions play in organizing biomolecules at molecular length scales. In essence, we seek to understand how life works at tiny, nanometer length scales.
An active area of research by our group is in the biological frontier of glycobiology. Every living cell in the body is coated with a sugary film called the glycocalyx. We are currently investigating how these sugars spatially configure the machinery of signal transduction. In cancer, we’ve discovered that these sugars are anything but sweet, and play a major role in the development of aggressive, lethal cancers. Our hope is to understand how these sugars modify signaling in disease specific contexts, such as cancer, and what role metabolism plays in organizing signaling molecules through regulation of these sugars. Our methodology is highly interdisciplinary, and includes approaches from computational biology, molecular biology, cell biology, super-resolution optical imaging, and glycobiology.
