Shubha Venkatesha Iyengar

Shubha Venkatesha Iyengar spent 46 years at the National Aerospace Laboratories in Bengaluru, building instruments that keep planes safe in bad weather. In 2026 she was named for the Padma Shri in the field of science and engineering, from Karnataka ^[1].

Training

Iyengar was born on 14 May 1954 ^[2]. She took her BSc in physics in 1972 and MSc in physics with electronics in 1974 from Bangalore University, coming first both times ^[2]. She joined CSIR-National Aerospace Laboratories (NAL) as a junior research fellow in November 1974, earned her PhD from Mysore University in 1981, and retired in 2020 as a CSIR Distinguished Scientist ^[2].

Instruments

Her early work built low-cost instruments for studying materials at high pressures and temperatures, at a time when such tools were not available in India ^[2]. NASA published three of her papers as official reports in 1986 ^[2].

Drishti

Her best-known work is Drishti, a system that measures visibility on runways, and an aviation weather observation system ^[2]. Both are now required equipment at Indian international airports, and Drishti is also used by the Indian Air Force ^[2]. The World Meteorological Organization and the International Civil Aviation Organization have recommended them to other countries ^[2].

She also developed components that withstand very high temperatures for India’s missile and ramjet–scramjet engine programmes ^[2]. She received the CSIR Young Scientist Award in 1989 ^[2].
