Principal Scientist @ PhagePro

May 7, 2021

PhagePro is a preclinical global health biotech startup in Boston. We aim to use bacteriophages (phages), which are viruses that specifically target and kill bacteria, to prevent bacterial infections. With the unmitigated rise of antibiotic resistance and the known negative consequences of gut dysbiosis caused by broad-spectrum antibiotics, bacteriophages provide a side effect-free alternative for preventing disease in clinical and community contexts.


As a mission-driven biotech company, we are a small, but growing phage company that prioritizes global health. We believe health is a human right, and our team is dedicated to helping make that a reality through our innovative phage-based products.


Our first product is focused on the prevention of cholera. Cholera is a disease that affects vulnerable communities and is spread primarily through contaminated water sources due to a lack of adequate sanitation infrastructure. Roughly 1.3 billion people around the world are at risk for cholera. The World Health Organization estimates that there are at least 3 million cases annually, approximately 40 percent of which are spread through household transmission. 


Household members often present with cholera symptoms two to three days after the initial patient becomes sick. There is currently an unmet need for a clinical intervention to stop the household and community spread of cholera using a rapidly active prophylactic treatment. PhagePro is seeking to fill this gap with its first phage-based product, ProphaLytic-Vc (PVC).


The Opportunity

PhagePro is looking for a Principal Scientist to lead our preclinical research on PVC as we prepare for clinical trials. The position is located at PhagePro’s lab space at the Tufts Launchpad in Boston, MA and will include domestic/international travel 5-10% of the time.
