Major Professional Contributions:

Guided successfully 19PhDs (2more under Progress) & 5 MScs (Research),More than 120 Papers in Int Journals & Conferences'
Successfully carried out several Projects from UGC,DRDO, BARC etc;
Funded by Aeronautical Dev Agency: Designed, got built, commissioned a Comprehensive LIGHTNING TEST FACILITY (LTF) comprising - 4 Million volts Impulse voltage generator, 4 Current Generators (200,000Amps, 100,000Amps, 5000 Amps,200Amps ) to generate WORSE THAN THE WORST REAL-LIFE LIGHTNING.Advised on Lightning-protection schemes for susceptible components of the Prestigeous LIGHT COMBAT AIRCRAFT(LCA) ,successfully evaluated them by subjecting to appropriate Lightning discharges at LTF.An EXPLOSIVE ATMOSPHERE TEST FACILITY has been built
wherin Fuel-carrying components of LCA are filled with highly ignitable vapours &
subjected to appropriate Lightning Discharges. For the FIRST TIME IN THE WORLD A FULL HALF WING HAS BEEN SUCCESSFULLY TESTED.at LTF. Based on these LCA has been declared Lightning-worthy.
Designed Lightning Protection Schemes for the two Satellite Launch Pads at Sriharikota.They have proved successful in avoiding Lightning strokes to the Launch Vehicles (with Satellites).
Successfully designed several High Voltage labs the largest being the Lab of Crompton Greaves capable of testing 1200 kV System apparatus to International Standards.Compares very favourably with the best in the World.
Designed & assisted in building a Nanosecond rise-time, 800 kV Pulse Generator for LRDE.Designed a Less-than a Nano-second rise-time 300kV Generator for BARC.
Guided development of two vegetable seed oils for use in Power Transformers as well as High frequency high High voltage transformers.Patents have been applied for them..
