TheIndian Institute of Science (IISc) offered Sood the post of an associate professor at the institution in 1988,[5] which he accepted. In 1994, he was promoted as the Professor of the Department of Physics at IISc.[5][7][14] Four years later, he rose to the position of the chairman of the Division of Physical and Mathematical Sciences, IISc, which he held until 2008.[5] Sood has also been holding the position of the honorary professor at theJawaharlal Nehru Centre for Advanced Scientific Research,Bengaluru since 1993.[3][5][6]
Sood, through his experiments in 2003, generated electrical signals by passing liquids over solids or through nanotubes and this phenomenon has now been termed by the scientific world asSood Effect.[5][13][15]
Sood, along with his team of scientists at the Indian Institute of Science, has done experiments onsemiconductorsuperlattices,fullerenes,solid C60,C70[16] and single walledcarbon nanotubes and reported to have unearthed new concepts onoptical phonons.[5][17][18] He was successful in exciting squeezed phonon states in KTa03 crystals, reported to be for the first time, by usingfemtosecond laser pulses and employing impulsive simulatedRaman scattering.[5][19] He has also discovered that liquid flow in a singled walled carbon nanotube induces the voltage and current to flow along the floor direction of the tube.[5][20]
Sood has also experimented withsoft condensed matter likemicelle composedviscoelastic gels which establish adeterministic spatiotemporal chaotic dynamics in the nonlinear flow regime.[5][21] He has also invented an ultrasensitiveimmunoassay by subjecting colloids to an electrical field, thus generating nonequilibrium phenomena,[5] an invention that has relevance to the medical field.[13] He has developed a medical diagnostic kit, too, which is said to be useful for the diagnosis of diseases across the spectrum.[13]
Sood is now working on the modalities of enhancing the viscosity of a material by adding nanotubes without increasing its weight. This will, for example, enable us to make lighter weight bullet proof vests with increased efficiency.[13]
Sood was an executive editor of the international journal,Solid State Communications, with aSCImago Journal Rank (SJR) of 0.874 till November 2020.[4][5][24][25] He is also an editorial board member of the journals,Scientific Reports,Particle[26] andEPL (Europhysics Letters).[27]
Sood is a recipient of many awards and honours. He was awardedShanti Swarup Bhatnagar Prize, in 1990, by the Government of India.[3][4][5] In 2013, the Government of India followed it up with the fourth highest civilian award,Padma Shri.[9]
National Award in Nanoscience and Nanotechnology – [[Department of Science and Technology (India)[5]|Department of Science and Technology]],Government of India – 2006[3][4]
Sood has published over 290 research articles and papers in national and international peer-reviewed journals.[4][7] His articles have been published in book format, too.[28] A random selection of his articles are:
