Biography

Vivek Maheshwari's research focus is on synthesis and assembly of nano-materials. The aim is to develop materials with properties that present applications in development of new electronic devices, sensors and integration of cells with an electronic interface. This presents a threefold challenge: synthesis and assembly of nano material, interfacing of the material to build devices and cellular electronics and finally testing and analysis of the devices for further research and applications.
