Course Overview

Course Description

A self-paced course on the design principles underlying mechanisms of cellular and biomolecular functions such as cell architecture, energy storage and conversion, sensing and signaling, communication, time keeping, molecular synthesis, memory, and motility. Emphasis will be placed on the chemical, physical, and mathematical features that determine the performance of the biological device. Topics cover both cellular/biochemical processes and molecular/genetic circuits. Examples are presented from reverse engineering of natural systems and design of new synthetic systems.

Living cells have unique functions that can be harnessed by engineers to tackle human problems in energy, water, food, and health.

Historically, living cells were considered too difficult to predictably engineer because of their complexity, vulnerability, and continuous change in state. The elucidation of the design principles that underlie cell function along with increasing numbers of examples of hybrid cell based devices are slowly erasing that notion.

In this class you will learn about these established and emerging cellular design principles and begin to view cells as machines. This knowledge can then be applied to non-living devices that mimic and communicate with cells. You will also be introduced to current and emerging living/non-living biohybrid devices such as biohybrid robots and neural implants.

What You Will Learn

  • How fundamental engineering principles apply to living cells.
  • What engineering principles can tells us about how cells function.
  • Established and emerging equations, models, and design curves that can be used to tune, re-engineer, or build new cells.
  • A framework for measuring and controlling cells as microdevices.
  • An introduction to emerging biohybrid devices.


  • A basic knowledge in cell biology and math up to calculus and differential equations.
  • Anyone with knowledge of undergraduate engineering or science could successfully take the course
