Dr. Ganeshkumar has a background in microelectronics, nanofibers, and its applications. His doctoral dissertation focused on synthesis and characterization of lead-free ferroelectric nanofibers for sensor and energy harvesting applications. This involved the facile and cost-effective fabrication of nanostructures in order to construct readily embeddable composites for flexible piezoelectric nanogenerators. He also specialize in using state-of-the-art scanning probe microscopy techniques to systematically investigate ferroelectric behavior and decouple tip-surface interactions in nanostructures.

Dr. Ganeshkumar has developed CMOS-based thermal actuators for optical MEMS applications. Also, he has experience in a wide variety of laboratory applications, including cleanroom fabrication, spectroscopy, dielectric and electromechanical test systems. Additionally, he has taught undergraduate level courses in areas such as design and fabrication of MEMS and Smart Sensors.

In his previous experience, Dr. Ganeshkumar has involved in prototype design, lab sensor testing, competition analysis, reverse engineering and benchmarking of environmental MEMS sensors (pressure and humidity). His responsibilities include prompting solutions to Asia Pacific customers on smartphone camera sensors and modules.
