Prof. Prabhu Rajagopal l"Brain drain isn't about salary. We want to be challenged"| Ep. 3

From CFI to commanding robots underwater, from ultrasonic waves to blockchain elections - Shanti Swarup Bhatnagar laureate Professor Prabhu takes us through his extraordinary journey of bridging deep science with entrepreneurship at IIT Madras. As a professor nurturing 7 groundbreaking startups, he's helping transform student experiments into pioneering companies, one innovation at a time. Discover how this former 'Gandhi' of IIT Madras is redefining the boundaries between academic research and entrepreneurship, creating what he calls an 'innovation continuum' - where lab projects evolve into cutting-edge solutions for real-world problems. In this episode, Prof. Prabhu reveals: - How CFI transformed student culture from "repairing fans" to "building rockets" - The untold story behind his 7 startups and the evolution from deep tech to AI - Why PhD students are now choosing entrepreneurship over traditional careers - The unique innovation stack that makes IIT Madras the best place to build 00:00:00 - Introduction 00:02:41 - Shanti Swarup Bhatnagar Prize 00:04:56 - Innovation Stack at IIT Madras 00:10:31 - Changing Academic Culture 00:12:56 - His first three startups 00:21:48 - TRL (Technology Readiness Level) Breakdown 00:23:23 - Solving industry oriented problems 00:25:06 - CNDE Lab and associated Startups 00:29:11 - How Blockchain is critical to AI 00:30:30 - Engineering and Technology have always been cross-disciplinary 00:34:34 - Research at IIT Madras is increasingly product and startup oriented 00:35:13 - His life at IIT Madras 00:41:15 - Poetry and Philosophy 00:45:01- Startup Ventures 00:47:00 - Foundational Robotics Work 00:48:20 - What makes IIT Madras the Best Place to Build?

WHAT IT’S REALLY ABOUT

IIT Madras’ innovation stack fuels deep-tech startups beyond salaries alone

  1. Rajagopal argues “brain drain” is less about salary and more about access to challenging, high-impact problems, which India increasingly offers through stronger ecosystems.
  2. He maps IIT Madras’ “innovation stack” from student making (CFI) through pre-incubation (NIRMAN), commercialization pathways (GDC/IC&SR), and full incubation, enabling both student- and research-led ventures.
  3. He describes multiple CNDE-linked deep-tech startups (robotics, sensors, AI for inspection, blockchain-healthcare), showing how lab-to-field translation bridges the TRL “valley of death.”
  4. He frames non-destructive evaluation (NDE) and guided ultrasonics as inherently cross-disciplinary, naturally evolving toward AI, cybersecurity, and data integrity challenges.
  5. He connects personal foundations—alumni networks, philosophy, and poetry—to a broader worldview of truth, auspicious impact, and beauty shaping his approach to research and innovation.

IDEAS WORTH REMEMBERING

5 ideas

Ecosystems retain talent by offering hard, meaningful problems.

Rajagopal says students left India earlier not only for better pay but to find intellectually demanding, high-impact work; as those opportunities emerge locally through startups and industry-linked research, more graduates stay.

IIT Madras’ advantage is a connected pipeline, not a single program.

He highlights a repeatable flow: student building at CFI, entrepreneurial grooming at NIRMAN (pre-incubation), and industry/commercial support via IC&SR, GDC, and the Incubation Cell—allowing multiple entry points for students and researchers.

Startups are a practical solution to the TRL “valley of death.”

Academic labs usually stop at TRL 1–3 (proof-of-concept), while field deployment requires TRL 7–9; Rajagopal positions startups as the commercialization arm that carries lab IP through tailoring, pilots, and deployment.

NDE is a safety-critical discipline with huge infrastructure relevance.

By “seeing inside” structures without damage (ultrasound, X-ray analogies), NDE prevents catastrophic failures in aging assets like bridges, dams, tanks, and pipelines—making it a strong base for impact-driven ventures.

Robotics becomes valuable when paired with sensing and analytics.

Planys and Solinas show that robots aren’t just mobility platforms; their advantage is carrying inspection sensors into inaccessible environments and turning large inspection datasets into actionable maintenance decisions.

WORDS WORTH SAVING

People used to discuss, ‘Oh, IITians do not get enough package, so they're not staying behind.’ But it is not about, just about the salary. I think a lot of us here want to be challenged.

— Prabhu Rajagopal

CFI is, is at the heart of it… look around here… people building racing cars… Hyperloop… sounding rockets… on their own.

— Prabhu Rajagopal

TRL 3 is actually proof of concept… Traditionally… IIT would be involved in one, two, three… and we stop there… So that's—this is the valley of death, typically.

— Prabhu Rajagopal

I firmly believe… the promise of AI cannot be unlocked without blockchain on the back end… blockchain… protect[s] the fidelity of the data.

— Prabhu Rajagopal

Engineering and Technology have always been cross-disciplinary… none of us today are… practitioners of our core disciplines anymore.
