Dr Vijaykumar Varma

Senior R&D scientist and team lead in thermal engineering, simulation and advanced materials, hands-on from model to hardware.

R&D leader who builds teams, labs and programmes where thermal engineering, microfluidics and AI-driven materials discovery meet.

Technical co-founder and CTO candidate for deep-tech: I have built labs, devices and data pipelines from nothing, and taken them to industry partners.

16 years of research since 2010, across India, Singapore, Luxembourg and Belgium. I led a five-person team for five years at NTU Singapore, set up two labs from scratch (programmes of ~$1.01M and S$970k), and wrote €3M+ in funding proposals as PI at LIST Luxembourg. Today I deliver high-throughput liquid-cooling simulation for imec’s AI-chip roadmap.

I still run the simulations and build the hardware myself, and I have led the team, budget and partnerships around it. Five years leading a five-person team of scientists, 29 devices delivered, 5+ industry partners, and now 3,000+ AI-chip cooling simulations for imec in under a month.

I build autonomous, AI-guided experimentation platforms and the groups that run them. Five years leading a research team at NTU Singapore, PI at LIST Luxembourg, two labs set up from scratch, 35 publications, and mentees who are now an assistant professor, a principal engineer and a staff engineer.

Thermal and microfluidics expert for AI hardware. I run automated CFD/CHT programmes for next-generation liquid-cooled GPU and HBM stacks at imec, and I have designed, built and validated 18+ cooling devices that beat conventional designs by up to 300%.

16 years turning physics into hardware: two labs set up from zero (~$1.01M and S$970k programmes), a provisional patent, 5+ industry partners, €3M+ in non-dilutive proposals written as PI, a LIST commercialisation project, and an advisory role at M3TRL Consulting.

Illustrative self-driving lab: a Bayesian optimiser picks each next experiment across an alloy-composition space and homes in on the best material in a few dozen runs instead of hundreds.
Illustrative temperature field: coolant crossing a micropillar cold plate above two chip hotspots, the kind of design space my simulation programmes sweep thousands of times.
