Tessy Thomas, Gagandeep Kang, Soumya Swaminathan — Saluting The Indian Women In Science
Indian women in science: From Tessy Thomas to Gagandeep Kang, and Vidita Vaidya to Soumya Swaminathan, women scientists have made India proud with their milestones.
India at 75: Indian women have accomplished historic breakthroughs in science since the 1800s. Through their achievements in different scientific fields including physics, astronomy, space, astrophysics, biology, neurobiology, medicine, and computer science, Indian women have earned titles such as the nation's 'missile woman', 'rocket woman', and 'weather woman', among others.
From Tessy Thomas to Gagandeep Kang, and Vidita Vaidya to Soumya Swaminathan, women scientists have made India proud with their milestones.
As India celebrates Azadi ka Amrit Mahotsav to commemorate 75 years of independence, here is a list of inspiring women scientists of the nation.
Tessy Thomas
Tessy Thomas, a scientist at the Defence Research and Development (DRDO), served as the project director for the Agni IV and V missiles. In 2011, she became the first woman to lead missile teams in India.
Dr Thomas is known as the 'missile woman' of India. The Agni IV and V missiles are intercontinental ballistic missiles (land-based, nuclear-armed ballistic missiles with a range of more than 5,600 kilometres) that have very high ranges and are capable of carrying nuclear warheads (explosive head of a missile or a similar weapon).
Dr Thomas' knowledge on the solid propellant systems played an important role in the development of the re-entry system of the missiles, helping them withstand great velocities and temperatures of 3,000 degrees Celsius on re-entering the atmosphere.
According to the Department of Biotechnology, Union Ministry of Science and Technology, Dr Thomas received the 'DRDO Scientist of the Year' Award in 2008, the DRDO Performance Excellence Award in 2011 and 2012, and the Lal Bahadur Shastri National Award for Excellence in Public Administration in 2012, among others.

Kalika Bali
Kalika Bali is a researcher at Microsoft Research India working in the areas of Machine Learning, Natural Language Systems and Applications, and Technology for Emerging Markets. Bali's research interests lie broadly in the area of Speech and Language Technology.
According to Microsoft, Bali is currently working on Project Mélange, where the researchers try to understand, process and generate Code-mixed language data for both text and speech. Code-mixing or use of more than one language in a single conversation is a phenomenon that is observed in all multilingual societies, and though Code-mixing has been studied in the past as a feature of conversational speech, the rapid rise of social media has made it a common phenomenon for text as well.
Bali is passionate about Natural Language Processing (NLP) and Speech Technology for Indian languages, and believes that local language technology, especially with speech interfaces, can help millions of people gain entry into a world that is till now almost inaccessible to them. NLP refers to the branch of artificial intelligence concerned with giving computers the ability to understand text and spoken words in the same way human beings can.
