• Responsible for ensuring the successful product delivery of Cisco's Optical Modules to Tier-1 webscale customers, focusing on key metrics like yield, cost, time to market, performance, and reliability • Managed and balanced competing product delivery metrics, including yield, performance, reliability, cost, and capital expenditures, while overseeing FA (Failure Analysis) activities. Collaborate effectively with diverse personalities within highly competent cross-functional engineering teams • Lead and facilitate multiple DfX (Design for Excellence) activities for HVM (High Volume Manufacturing) in collaboration with cross-functional teams, including Marketing, Engineering, Process, Test, Reliability, Supply Chain, Cisco’s Technology-and-Quality Organization, Suppliers, and Contract Manufacturers • Demonstrated significant contributions to Cisco Optics, highlighted by receiving a recognition award for resolving a critical thermo-mechanic issue on a key product, resulting in on-time delivery to a crucial webscale customer in June 2023

• Lead FEA/CFD team for state-of-the-art optical transport products from component-level (e.g. LCoS, MEMS) to modules (e.g. optical switch, Lidar) to system-level with stringent performance/qualification requirements • Solved many technical challenges in the design of new products resulted in multiple Recognition Awards • Patented thermal/mechanical designs during new technology/product development • Innovated/invented technologies used in market-leading telecommunication products sold to Tier-1 customers • Responsible for thermal, mechanical, thermo-mechanical and opto-mechanical design of wavelength selective switch (WSS) products with challenging design/cost/size requirements. • Continuously developed best-in-class products/technologies by performing in-depth: o Thermal CFD analysis to predict thermal behavior, heatsink optimization, TEC design, TIM optimization, etc. o Thermal stress analysis to make sure products survive temperature cycling NEBS tests o Shock response spectrum analysis for impact survivability o Explicit dynamic analysis using LS-DYNA (passing drop tests) o Harmonic response / random vibration analysis to ensure passing operational vibration tests o Opto-mechanical analysis – Structural, Thermal and Optical Performance (STOP) analysis o Stress-optic and Thermo-optic effect in optical performance o Epoxy selection (DMA/TMA)

Lumentum was formerly known as JDSU. JDSU split into Lumentum and Viavi in Sep 2015.

Invented an opto-mechanical system to measure mechanical properties of compliant materials (resulted in a US Patent) Designed and developed novel optical sensors for robotic graspers (published in highly-reputed journals) Designed a mechanism for robotics that won the Canadian Institute for Photonics Innovation Award Prototyped silicon-based sensors at McGill Micro-fabrication facilities. The project was selected among the best examples on the Micro-fabrication website of McGill University Developed hyperelastic/viscoelastic material modeling (won Canadian Precarn National Scholarship)
