“I believed in the power of PhysioPD when I first saw it twenty-five years ago, I’ve had a passion for it ever since, and now we have enough experience that I know it works.”


About Rosa & Co
Rosa was founded in 2002 and remains an employee-owned, science-focused, and client-friendly firm. Today, Rosa is the worldwide commercial leader in PhysioPD-style Research, with comprehensive basic biology and therapeutic experience, industry-leading modeling expertise, and repeat research engagements with a majority of the Top 20 pharmaceutical companies.
Rosa Market Modeling, which offers a credible methodology for determining expected physician uptake for healthcare products, was started by Bill Brastow, Ph.D., in 2005. Our models have helped shape first-in-class markets including novel therapy combinations for HIV and molecular diagnostic tests for Oncology.
Rosa’s staff bring more than a century of aggregate experience in applying modeling to the inherent challenges faced by drug developers and have authored hundreds of scientific posters, conference presentations, relevant patents, and peer-reviewed publications.
