Our Company

Parse Biosciences is a Seattle-based company with the mission of accelerating progress in human health and scientific research.
At the core of our company is our pioneering approach for single cell sequencing. Single-cell sequencing has already enabled groundbreaking discoveries which have led to new understandings of cancer treatment, tissue repair, stem cell therapy, kidney and liver disease, brain development, and the immune system. At Parse Biosciences, we are providing researchers with the ability to perform single cell sequencing with unprecedented scale and ease. 

Our Team

Our interdisciplinary team is built from top recent college graduates as well as seasoned experts.
We are rapidly expanding, always seeking to add team members who complement each others’ backgrounds at the intersections of cellular biology, computational biology, genetics, business management, and marketing.


Alex Rosenberg, PhD

CEO and Cofounder


Alex cofounded Parse Biosciences and leads the company as the Chief Executive Officer. He earned his PhD in Electrical Engineering from the University of Washington, where he combined synthetic biology, next-generation sequencing, and machine learning to create predictive models of biology. As a postdoctoral and Commercialization Fellow at the University of Washington, Alex co-invented a new scalable approach to single cell sequencing which became the basis for Parse Biosciences. He has been widely published in journals such as Cell and Science and holds a BSE in Electrical Engineering from the University of Michigan.


Charlie Roco, PhD

CTO and Cofounder


Charlie cofounded Parse Biosciences and leads as its Chief Technology Officer. He brings a decade of experience in biology-based technology development. He completed his PhD in Bioengineering at the University of Washington, where he was awarded several fellowships from the NIH and the Fred Hutch Cancer Research Center to develop a new scalable approach to sequencing. This work led to multiple publications in Science and the founding of Parse Biosciences. Prior to the University of Washington, he worked at the Wyss Institute at Harvard and University of Pennsylvania in fields of drug delivery and microscopy. He holds a BSE in Biological Systems Engineering from Virginia Tech.



Our offices and lab are located in the Waterfront Research Center in the heart of downtown Seattle.

Sitting across the road from Myrtle Edwards Park, this 5-story life science building that we call home overlooks Elliott Bay.
