In 1985, Lee was elected Member of the United States National Academy of Engineering for his original research on control valve stability, for innovative dynamic measurement instrumentation, and for successful entrepreneurial commercialization of his inventions. Lee has been granted many US patents.
Lee is a notable businessman and founded or co-founded several companies specialized in process control and hydrodynamic instruments. Lee co-founded the Setra Systems Inc. with his brother Y. T.
