Thermal Engineer (R&D) at Infiniflux Ltd (2025-08 – Present)

• Develop advanced two-phase Direct-to-Chip (D2C) liquid cooling systems for high-performance data-centre applications, supporting GPU heat loads approaching 1000 W per chip at operating temperatures around 40 °C.
• Designed and evaluated cold plates, manifolds, and refrigerant distribution architectures for next-generation AI and data-centre cooling systems.
• Performed Design-for-Manufacture (DFM) reviews considering machining constraints, sealing strategies, leak prevention, and assembly robustness.
• Led thermal and hydraulic performance evaluations, balancing heat transfer, pressure drop, reliability, and manufacturability.
• Conducted root-cause investigations on thermal performance and assembly issues using experimental testing and engineering analysis.
• Worked closely with suppliers and manufacturing partners on prototype development, component sourcing, fabrication reviews, and quality verification.
• Developed engineering documentation including test procedures, risk assessments, SOPs, and validation reports.

Researcher (Thermal & Mechanical Systems) at University of Hertfordshire (2021-11 – 2025-07)

• Designed, built, and tested liquid-cooling rigs and biomimetic cold plate heat sinks for high-power electronics and CPU thermal management.
• Developed and validated thermal solutions for Intel Xeon processors under high heat-flux and elevated thermal design power conditions.
• Performed CAD-based mechanical design, experimental validation, data acquisition, and performance optimisation of cooling components.
• Conducted failure analysis and performance investigations to identify thermal bottlenecks and optimise cooling effectiveness.
• Managed instrumentation and calibration (pressure, temperature, flow rate), ensuring accurate measurement and repeatable testing.
