Physiology and Medicine
Our ability to advance medicine is limited by the rate at which we can conduct human experiments and the translatability of our experimental models. Improving medicine by expanding our understanding of and ability to modulate living humans. Aging research requires that we understand what’s happening in humans over long timescales, and that we can identify biomarkers that can proxy these trends.

Current preclinical models of human physiology, including animals and organoids, do not fully capture the complexity of human physiology, limiting the predicting power of preclinical experiments and explaining, in part, the costly failures of drug development in clinical trials. This is especially true for complex disorders including those of aging, neurological disorders, and female reproductive biology. More systematic and representative models—including ex vivo human organ systems or even whole bodies and novel animal species—are needed to improve the predictive power of biomedical research. These technologies also have applications in addressing organ shortages, improving neonatal care, and other unmet medical needs.
Our understanding of human physiology and disease remains incomplete. In the last century, we have developed cures for many diseases with well-defined root causes (polio, smallbox, cholera, SMA, cervical cancer, etc.). However, a wide array of conditions still eludes cures and treatments. We have yet to fully decipher the dynamic interplay between brain and peripheral systems, the bioenergetic processes underlying chronic conditions, and the multifactorial pathways that drive aging. The biological mechanisms driving complex diseases and the aging process are multifactorial, involving multiple interacting pathways.
Although we understand some individual aging mechanisms, we do not yet have line of sight to comprehensively rejuvenating mammals or extending lifespan. To overcome these challenges, we need combinatorial approaches that can modulate multiple mechanisms simultaneously, allowing us to measure multi-system impacts and develop effective interventions.
Drug development is often hampered by failures related to absorption, distribution, metabolism, excretion, and toxicity (ADME/Tox). Improved predictive models for molecular interactions are essential for designing safer, more effective drugs, as well as evaluating the impact of environmental chemicals.
Additionally, there is a significant gap in our knowledge of what exactly is present in foods and how these components affect human biology. A comprehensive mapping of the “foodome” and studies on food component functionality are needed to advance nutrition science and personalized dietary interventions.
