My research is focused on the following thrust areas:

Micro-Nano Scale Process Technologies and Biosensors.
Micro-Nano systems and Devices
Intelligent controller development.
Additive Manufacturing.

The process technologies and micro machines are designed such that they could be applied to make micro-nano systems and devices. Few of the process technologies on which I work are micro turning, micro milling, micro EDM and laser micro machining. These includes precise controls and instrumentation strategies. Along with all these I work on development of micro-nano scale devices where flexible electronics and nanotechnology comes in. The focus is on development of some viable commercial product which focuses on indigenous technology development important for Indian market. As an application we develop various nano-biosensors that could aid the healthcare sector.

Technologies developed and licensed by my group:

Multi Fab micro machining center

The developed system is a micro machining platform for manufacturing miniature parts, patterns and surfaces in micro meter scale dimensions. The developed machine has an unprecedented accuracy of 1 micron and can machine over metals and polymers. The machine can conduct operations such as micro turning/ micro milling/ micro drilling/ micro patterning. The controller/ software is developed indigenously. The technology is licensed to M/S NHIT Durgapur and Manbhum Pvt. ITI Purulia West Bengal, India. The technology has immense industrial as well as societal applications. The technology aids the Indian MSME industries involved in surgical tool manufacturing, artificial jewelry manufacturing etc. Since the developed system is affordable the system aids Indian engineering colleges to install their own CNC facilities which are generally of high cost when imported.

Nano Laser micro nano scale laser machining center

This technology was focused on development of a laser micro manufacturing system which could generate patterned structures on surfaces ranging from 300 nm to 300 microns. These patterned surfaces have immense applications in hydrophobic surface generation, bacteria repellent surfaces etc. The technology was licensed to two different Indian industries namely M/S Nag Enterprise, Birbhum, West Bengal and M/S Tequity Ventures, Mumbai, Maharastra. The developed system was covered under various press releases.
