The Choi Lab develops new synthetic biology tools to study cell-fate decisions in development. During development, cells differentiate into various cell types with distinct functions. To understand how different cell types are made, we need a tool to observe cells’ previous and current states, as well as the sequence of events they undergo. We focus on developing such new tools through:

  1. Cellular engineering
  2. Molecular circuitry
  3. DNA as an information storage medium, and
  4. Synthetic models for cellular development

These novel tools will provide new insights into understanding cell-fate decisions and facilitate cellular engineering for future therapy.
