A major focus of our lab is engineering innovation for analysis of complex biological systems — as is required to address questions important to both fundamental biological systems and applied clinical research. We employ a combination of approaches drawn from bioengineering, chemical engineering, mechanical engineering, and electrical engineering with strong foundations in biology, materials science, and analytical chemistry. In essence, we strive to advance the “mathematization” of biology & medicine.

The Herr Lab at UC Berkeley’s Stanley Hall

We are part of the UC Berkeley Department of Bioengineering and the UC Berkeley/UCSF Graduate Group in Bioengineering. A primary focus of our research is in tools to push the frontier of single-cell biology. To accomplish this, we design and create instrumentation that exploits scale-dependent physics and chemistry. Our work accelerates development of bioanalytical methods, streamlines sample preparation strategies, improves biomarker validation studies, and advances clinical diagnostics.

Graduate student researchers join us from a variety of UC Berkeley & UCSF Graduate Programs: BioengineeringChemical Biology, and Applied Science & Technology, as well as various engineering & chemistry programs.
