Dr.Babu Padmanabhan phd

Dr. Babu Padmanabhan is an Entrepreneur and Researcher with the mission to make breakthroughs in the field of Polymer Science.

He founded STEER in 1993 which specializes in Twin-Screw Extruders (TSE) and TSE components. In a short span of just over a decade, STEER and BABU are synonymous in the area of Twin-Screw Elements & Extrusion Technology.

He has done PhD in Mechanical Engineering from Virginia Polytechnic Institute and State University, Blacksburg, VA.

He has presented several papers relevant to the polymer industry in the area of processing section components.

He is also active in social service and feels the need to contribute to Human Development.
