Since he joined Drexel in 1985, he has developed a non-Newtonian flow and heat transfer laboratory and has initiated the investigation of a non-chemical water treatment technology to prevent fouling from various heat exchangers. He has been instrumental in developing a number of new technologies such as a new scanning capillary tube viscometer for blood viscosity measurement in clinical environments, and an electronic-descaling technology based on a solenoid-coil concept. Currently, he is developing methods of applying high-voltage plasma technology to wastewater treatment.

He received two NASA Space Act Tech Brief Awards (NPO-17237) and (NPO-16593) for his work on the flow visualization of tip vortex generated by a helicopter rotor blade. He was the recipient of the 1992 Lindback Award for excellence in teaching at Drexel University. In 1993, Dr. Cho was nominated by U.S. DOE and elected as the chairman of the Advanced Fluid Committee under International Energy Agency. In 1995, he was the recipient of the Research Professor of the Year at Drexel University. In 2019, Dr Cho was named a Fellow of the National Academy of Inventors.
