Pushan Ayyub was a Senior Professor and the Chairperson of the Department of Condensed Matter Physics at the Tata Institute of Fundamental Research till his retirement in 2019. In the general area of nanoscience, he has over 160 publications in international journals and has given invited talks at over 60 international conferences and many more national meetings. Prof. Ayyub was a member of the International Committee on Nanostructured Materials during 1998-2008, the Nanoscience Advisory Group (2008-14) and the Nano Mission Council of the Govt. of India (2014-18). His awards include the National Research Award in Nanoscience and Technology (2010). He is a Fellow of the Indian National Science Academy.
Pushan Ayyub completed his M.Sc. (Physics) from Jadavpur University (Kolkata) in 1980 and Ph.D. from TIFR in 1986 on the physics of nanomaterials. He carried out post-doctoral studies at the University of Florida and re-joined TIFR in 1990.
His research interests concern the size dependence of physical properties such as superconductivity, ferroelectricity, ferromagnetism, and optoelectronics in the nanometer regime. He showed that size-induced changes in crystal symmetry produce significant deviations in important properties, and may also stabilize novel crystal structures. His studies have helped to define a lower limit to the miniaturization of ferroelectric devices and led to a deeper understanding of size effects in conventional superconductors. His research on one-dimensional nanomaterials has uncovered novel nanotech applications such as new electron and x-ray emitters and in environmental remediation. Professor Ayyub has conducted his research almost exclusively in India, and many of his papers are highly cited.
