Before taking up her present position as technical director at Intercable GmbH, Italy, she spent about 12 years in industry. Starting from being a senior scientist in Research & Development in the field of polymer engineering, she successfully builts up a new innovative business unit at ElringKlinger Kunststofftechnik GmbH, which she led for several years and thus became general manager at Schlemmer Group. She has authored several scientific publications and three books.
 
Vibunanthan Muralidharan obtained his Master of Science (M. Sc.) in Polymer Technology at the University of Aalen, Germany, after completing his Bachelor of Engineering (B. Eng.) in Mechanical Engineering in Chennai, India. He then went on to do research work in the field of polymer and rubber materials with a specialization on the dynamic behaviour of rubber materials, under the supervision of Prof. Dr.-Ing. Achim Frick for an extensive period of time. He presently holds the position of Testing and Process Optimization Engineer at Vorwerk Autotec GmbH in Wuppertal, Germany, where he is responsible for the testing and evaluation of various elastomer bushings and damping elements for automobiles.
