Compound chips are thoroughbred racehorses

Among the luminaries of India's cutting-edge military scientific research and development, Suma Varughese was one of the scientists behind the success of India's home-made airborne surveillance systems.

She is now leading efforts for the development of indigenous compound semiconductors. In an interview, she told THE WEEK that breakthroughs with regard to compound chips are not just technical milestones, but also declarations of technological sovereignty. She also explains how a sensor senses. Edited excerpts:

Q When and how did your journey as a military scientist begin?

It was 1986. I had just cleared my bachelor's in science with distinction from Bangalore University in a year when the pass percentage was 5 per cent. The result filled me with confidence; I was certain I would pursue physics. I applied, but despite my marks, I didn't make the cut.

The disappointment stung. I felt lost, wondering what to do with all that energy and ambition. Then, I spotted an advertisement-the DRDO was recruiting fresh graduates for a unique programme. It wasn't just any job; it was an opportunity to pursue an MSc in computer science-a field barely anyone knew about back then-with full stipend that covered all my expenses and more.

I appeared for the written test, cleared the medical examination and faced a gruelling interview. When the selection letter arrived, it felt like the universe had handed me a better script than the one I had written for myself.

That day marked the beginning of an extraordinary journey. I stepped into the world of defence R&D and cutting-edge technology, never once looking back.
