Gratitude to the Tata Institute of Fundamental Research faculty.

Thank you for a career spent listening to hydrogen across billions of light years with the GMRT, and for leading TIFR with a working astronomer's steadiness.

Thank you for illuminating the deep connection between gravity and fluid dynamics, and for string theory lectures that generations of students treasure.

Thank you for showing how string theory can hold a stable vacuum, and for the years you gave TIFR as its Director while staying a working physicist.

Thank you for charting what neutrinos from a dying star can tell us, and for helping India dream seriously about its own neutrino observatory.

Thank you for proving the existence of Cannon-Thurston maps, and for living proof that deep mathematics and a contemplative life can be one vocation.

Thank you for tracing how early experience sculpts the brain's emotional circuits, and for mentorship that has changed Indian neuroscience as much as your serotonin work changed the field.

Thank you for revealing how a single gene can organise the developing brain, and for speaking up, year after year, for women in Indian science.

Thank you for coaxing quantum behaviour out of atomically thin devices, and for building world-class nanoelectronics in Mumbai.

Thank you for weighing the constancy of nature's constants with radio telescopes, and for finding galaxies in their most private, gas-rich years.

Thank you for statistical physics of rare clarity, and for the years you gave TIFR as Director, keeping India's finest research house both rigorous and kind.

Thank you for founding ICTS and for a life in string theory that gave Indian theoretical physics a global home of its own.
