Craig Watson is a biomedical engineer. He received his doctoral degree for his experimental work using microfluidics at Samuel Sanyo's lab at the Department of Biomedical Engineering, Case Western Reserve University, Cleveland Ohio.

This pressure regulator is an integral part of the all in one microfluidics control system developed by Craig Watson. But it is also used stand-alone. It controls pneumatically-driven microfluidic chips. It regulates output pressures by using Honeywell TruStability® Pressure Sensors and Parker Proportional Solenoid Valves for its closed loop PID control system. This system has a very quick response time. It is controllable via USB or by I2C. 

The device is very well suited  for applications with low air requirements and limited air supply (such as a portable device with on-board pump or only a small gas cylinder). However, high flow rates are handled equally well.
