Systems Biology

Systems Biology was pioneered in the early 2000s by P4Mi’s Founder and Board Chair, Leroy Hood, along with scientists at the Institute for Systems Biology in Seattle, Washington. Today, major universities and research institutes all over the world teach and practice systems biology.

Systems biologists think of biology as integrated systems of networks operating at the levels of molecules, cells, organs, and even social interactions among people. All of these networks, including your genes and your environment, interact to effect health. Visit for more.

P4 Medicine

P4 Medicine—Predictive, Preventive, Personalized, and Participatory—is the clinical expression of systems biology. P4 medical care treats your health as a single, unique, integrated system. It complements and enhances traditional disease-focused care by harnessing the power of 21st century science and technology to predict and prevent disease, to help patients feel good, to slow or even partially reverse biological aging, and to optimize their ability to move, think, and perform at their best in all aspects of life.

P4 medical care is highly personalized, recognizing that individuals respond very differently to lifestyle factors such as food, activity, and sleep, as well as to drugs and other types of medical interventions. These unique responses cannot effectively be inferred from population averages. That is why P4Mi’s medical programs focus on using the latest technologies to construct a dynamic personal data cloud for each patient as a foundation for care.

P4 medical care is highly participatory. It requires patients to work with their physician to understand their health status and how it is affected by their lifestyle and environment. Patients are experts in their own lives. At P4Mi, this expertise is central to the design of experiments used to discover and validate the best health solutions for unique individuals. By harnessing the power of personalized actionable information, P4 patients can make highly targeted, practical, and sustainable adjustments they know work for them.
