PhAST: The fastest Phenotypic Antibiotic Susceptibility Test



PhAST’s mission is to develop innovative diagnostic approaches to help solve the global challenge of antibiotic resistance.

We are passionate and committed to tackle one of today’s greatest threats to human health: antibiotic resistance. We are doing this by developing technology that significantly speeds up both the detection of bacterial pathogens in patient samples and the choice of the best antibiotic for treatment. Our technology leverages the power of single-cell imaging and microfluidic platforms to provide healthcare providers with the right diagnostic information at the right time. This will reduce usage of ineffective or excessive antibiotics, improve patient recovery through faster and more accurate diagnostics, and slow the spread of antibiotic resistance.



Award from the Longitude Prize Committee

“On November 21, 2016, PhAST was awarded the Discovery Award from the Longitude Prize Committee . PhAST is excited to compete in the Longitude 10 million pound Prize for a diagnostic test that contributes to solve the global problem of antibiotic resistance”.


Our team includes world-leading experts in single-cell microbial imaging and microfluidic systems.

Kwangmin Son

Kwangmin Sonm, PhD

CEO & Founder

Kwangmin is co-founder and CEO of PhAST. Kwangmin trained as an engineer working at the interface of mechanical and biological engineering at MIT, where he earned his PhD (2015) and worked as a post-doctoral researcher. Kwangmin brings strong expertise in combining microbial imaging and microfluidics, having worked on some of the most challenging bacterial and viral imaging problems to date. He hopes that PhAST’s diagnostic technology will significantly help reduce the mis-usage and over-usage of antibiotics, thus contributing to fight the spread of antibiotic resistance.

Roman Stocker

Roman Stocker, PhD

CSO & Founder

Roman is co-founder and CSO of PhAST. Roman is a professor of engineering at MIT (2005-present)’ and ETH Zurich (2015-present). Roman pioneered the field of environmental microfluidics, a single-cell imaging based approach to study the response of microorganisms to chemical and physical stimuli. Roman is a world-renowned expert in microbial biophysics, has worked with a broad range of organisms to date, and brings original engineering approaches to microbiological problems. In acknowledgement of his seminal work Roman has received major awards, including an NSF CAREER award and a prestigious Investigator award from the Gordon and Betty Moore Foundation. Roman has published nearly 100 papers, including more than 20 in Nature, Science and PNAS. Roman’s vision is that new, creative engineering technology can make a substantial contribution to the global problem of antibiotic resistance.



Kwangmin Son

Prof. Andrew Onderdonk is the Director of the Clinical Microbiology Laboratory at Brigham and Women’s Hospital in Boston and a Professor of Pathology at Harvard Medical School. His research encompasses several areas related to human microbial flora and its role in health and disease, including the pathogenesis of microorganisms and the in vivo and in vitro efficacy of antimicrobials. Dr. Onderdonk advises PhAST with information and feedback on clinical issues.

Roman Stocker

Prof. Marvin Whiteley is the Director of the LaMontagne Center for Infectious Disease at The University of Texas, Austin. Dr. Whiteley’s research focuses on antibiotic resistance and the development of therapeutics to treat polymicrobial infections. He has received numerous national and international awards and is currently a Burroughs Welcome Pathogenesis of Infectious Disease Investigator, a member of the American Academy of Microbiology, and a Kavli Institute Fellow of the National Academy of Sciences.
