About

Geraldine A. Hamilton is a pioneering figure in the field of organ-on-a-chip technology, where her work has fundamentally advanced the ability to model human physiology outside the body. Her primary research focuses on developing microfluidic devices that replicate the structure and function of human organs, and critically, on creating automated systems to link these chips together into a "body-on-a-chip" platform. Hamilton’s major contributions include the design of a robotic "Interrogator" instrument that can fluidically link up to ten different Organ Chips, enabling automated culture, perfusion, and real-time microscopic imaging. This breakthrough, detailed in a 2019 paper (8 citations), laid the groundwork for her most impactful work: a 2020 study on robotic fluidic coupling of multiple vascularized organ chips, which has garnered over 400 citations. By solving the challenge of integrating and automating multiple organ models, Hamilton has opened new avenues for drug testing, toxicity screening, and personalized medicine, reducing reliance on animal models. Her achievements represent a leap toward a truly interconnected human-on-a-chip system, making her a leading voice in the future of biomedical research.
