Four-decade data center pioneer, inventor on more than 160 patents, and member of the U.S. National Academy of Engineering will help DG Matrix build the intelligent power fabric for the AI data center.
DG Matrix, the global leader in solid-state transformer solutions, announced the appointment of Christian Belady, one of the most influential figures in the modern data center industry, to its newly formed Executive Advisory Board. Belady will also serve as a personal advisor to DG Matrix CEO Haroon Inam and work directly with the company’s engineering, solutions and commercial teams as DG Matrix builds the intelligent power fabric for the AI data center — the software- and AI-driven control layer that manages every watt flowing from the utility service through on-site generation, storage and power conversion & protection into the GPU.
Belady has spent more than four decades in the data center industry and is an inventor on more than 160 patents. He spent 16 years at Microsoft, where he served as a Distinguished Engineer. In 2023, he retired from Microsoft after 16 years as Vice President and Distinguished Engineer of Data Center Research and Development in the company’s Cloud Infrastructure Organization where he pioneered innovations in data center cooling and on-site power generation. For a decade prior, he led worldwide data center development across site selection, energy, engineering, construction and operations.
Belady originated the Power Usage Effectiveness (PUE) metric while at Hewlett Packard — a metric that has defined how the industry measures data center efficiency for two decades. He later co-authored Water Usage Effectiveness (WUE) and Carbon Usage Effectiveness (CUE) with The Green Grid, and has shaped standards work at ASHRAE and other industry bodies. His contributions have materially improved global data center energy efficiency over the past 20 years.

“Christian wrote the rulebook for how modern data centers are designed, sited and measured,” said Haroon Inam, CEO of DG Matrix. “He has been warning the industry for years that power is the binding constraint on cloud and AI growth, and that data centers need a power intelligence layer to match AI compute. Having him on our Executive Advisory Board and at my side as a personal advisor will sharpen how we build, deliver and service our solid-state transformer (SST) solutions — and accelerate our path to becoming the intelligent power fabric of the industry.”
Belady’s recent work has centered on the intersection of AI infrastructure, grid interconnection and the power fabric inside the data center — how power is converted, routed, controlled and delivered from the utility service to the GPU. DG Matrix’s AI-enabled Interport™ platform is built to become that fabric: collapsing multi-stage power conversion into a single, software-defined stage, absorbing GPU pulse loads, and actively controlling every watt flowing between the grid, on-site generation, storage, UPS and compute loads. DG Matrix also operates the largest solid-state transformer engineering team of any company in the world, giving the platform a multi-year lead on SST hardware, firmware and AI-driven control software.

“AI has rewritten the power requirements of a data center,” said Christian Belady. “Speed to inference is now speed to power. DG Matrix has built the first commercially available multi-port solid-state transformer by collapsing the data center electrical system of discrete devices into a single device just as semiconductor integrated circuits did with transistors, capacitors and resistors in the 1960s enabling hardware into a software- and AI-driven control layer for the data center power. That is the kind of architectural shift the industry needs, and it is why I am joining. I want to help this team transform data center design and delivery to energize in months rather than years… if not sooner!”
Since leaving Microsoft, Belady has served as an advisor and board member to several of the most prominent firms in digital infrastructure. He was recently elected to the U.S. National Academy of Engineering, one of the highest professional distinctions an engineer can receive. His industry recognitions include the 2017 DataCloud “Data Center Thought Leadership” Award, the iMasons “2020 Industry Luminary” Award, the 2023 Interglobix Titans List, the 2024 Northern Virginia Technology Council Data Center Icon Award, and the 2025 Data Center World Lifetime Achievement Award.
As a member of the DG Matrix Executive Advisory Board, Belady will advise on platform and solutions strategy, customer engagement and modular deployment architectures for AI data center developers. His appointment is the first in a series of planned Executive Advisory Board appointments and comes as DG Matrix accelerates deployments of its AI-enabled Interport™ platform with hyperscale, neocloud and colocation customers worldwide.
