Savas Tay is a systems biologist and bioengineer working at the interface of biology, physics, and engineering. His overarching goal is to understand how biological systems work from an engineer’s perspective and use this knowledge to manipulate cells and gene pathways to help cure diseases. On the technology front, his lab develops high-throughput and high-content single-cell analysis devices by integrating microfluidics, computation, and optics. Recently, Tay Lab developed a single-cell proteomics method that enables simultaneous measurement of proteins, protein complexes, and mRNA in thousands of individual cells.
A main focus for Tay Lab is to understand the role of molecular pathway dynamics in cellular information processing, pathogen sensing and recognition, and cellular communication. Tay Lab performs precision dynamic measurements on living cells and develops predictive models of complex systems like the immune system. Such models can serve as a rapid test-bed for drug studies and genomic perturbations.
Technologies developed by the Tay Lab create realistic microenvironments that mimic living tissue and measure dynamic processes in individual cells with extreme precision and throughput. Tay is also interested in translating such technologies to real-life biomedical applications.
Dr. Tay's work on NF-κB, a key transcription factor that regulates thousands of immune genes, was published in leading scientific journals such as Nature, Cell, and PNAS. He discovered that cells activate NF-κB in an all-or-none fashion, similar to a digital switch. Recently, he discovered that molecular noise improves cellular signal transmission and showed how oscillatory inputs control transcriptional dynamics by synergizing with molecular noise. His studies showed how local signaling dynamics regulate gene expression in space and time.
