From materials science to AI: Dr. Roisul Galib's journey to make materials manufacturable
From materials science to AI: Dr. Roisul Galib's journey to make materials manufacturable
Dr. Roisul Galib is a Materials Engineer at CLEAResult Energetics, where he provides technical and program support to U.S. Department of Energy (DOE) initiatives advancing next-generation energy materials. With a PhD in materials science and a decade of experience spanning metals, polymers, ceramics, composites, and semiconductors, he supports DOE's CABLE program on next-generation electrical and thermal conductors, as well as the Genesis Mission's work applying AI to accelerate materials discovery.
Some engineers spend their careers focused on a single material system. Dr. Roisul Galib has spent a decade focusing on nearly all of them, working across metals, polymers, ceramics, composites, and semiconductors, moving between university research and industry in pursuit of one connecting question: what does it actually take to move a material from a promising discovery in the lab to something that can be manufactured, deployed, and relied on at scale?
Starting with the fundamentals
His undergraduate focus was on materials science and engineering, where he learned the relationship that governs the field: how a material structure determines its properties, and how processing determines both. His earliest hands-on work applied that directly, developing new lead-free zinc-based alloys for high-temperature electronic packaging. The work meant running detailed thermal and mechanical testing to understand how interconnect materials behave, and fail, under harsh conditions. It was hands-on materials science from day one, and it set up a pattern he would follow for the next decade: start with a real engineering problem, understand it down at the level of the material, and push the work toward something that can be manufactured.
The physics of heat and current
That pattern carried him to graduate study, where he earned his Ph.D. studying how materials move heat and carry electrical current at the smallest scales. He examined how two-dimensional materials such as graphene integrate in next-generationmicroelectronics and used ultrafast laser spectroscopy to study how charge carriers move through compound semiconductors in fractions of a billionth of a second. The physics was exacting, and the goal behind it was practical: more energy-efficient, more reliable electronic devices.
From the lab bench to bigger systems
The years that followed took him from the lab bench out toward bigger systems. At a university-affiliated research foundation in western New York, he led development of a passive cooling film for buildings that used radiative cooling and evaporation to cut energy use without drawing any power, and he helped design a membrane technology that could pull carbon dioxide directly from the air using only solar heat. Alongside that research, he worked with an early-stage renewable energy company to help move a low-cost solar water-harvesting system out of the lab and toward production, learning firsthand what it takes to scale a material from a working prototype into a manufacturable product. Later, as a consultant to an energy research lab, he led development of a moisture-based electricity generation system that used engineered hydrogels to draw usable power from humidity in the air, aimed at powering off-grid electronics.
Arriving at CLEAResult Energetics
Taken together, that range gave Dr. Galib something unique: real fluency at every scale of energy technology, from the atomic structure of a material to the realities of manufacturing it in volume. In 2024, he brought that background to Energetics, part of the CLEAResult family, joining as a materials engineer to support the U.S. Department of Energy (DOE) on work his career had been building toward.
Building tomorrow's conductors: CABLE
Today, Dr. Galib provides technical and program support to CABLE (Conductivity-enhanced materials for Affordable, Breakthrough Leapfrog Electric and thermal applications), a DOE initiative focused on next-generation electrical and thermal technologies that remain affordable and manufacturable at scale. He evaluates emerging conductor technologies and manufacturing pathways, tracks program milestones, verifies long-term performance claims, and turns research results into summaries DOE stakeholders can act on. The work touches nearly every corner of the energy system these conductors could transform, including grid modernization, data center power and thermal management, and electric vehicles.
Speeding up discovery: Genesis Mission
He also supports the Genesis Mission, a national DOE initiative connecting supercomputers, research facilities, artificial intelligence (AI) models, and scientific data across national labs, industry, and academia to shorten the path from scientific discovery to deployed technology. On this effort, Dr. Galib helps shape project scope, reviews progress against milestones and assesses where AI-driven approaches to materials discovery are ready for real use and where they still need more groundwork, work that sits directly at the intersection of his materials background and his interest in using AI to speed up how new materials move from concept to deployment.
A fitting place to land
From materials a single atom thick, to thin films that cool entire buildings, to national programs reshaping the conductors at the heart of the energy system, Dr. Galib has spent his career connecting the science of materials to the systems they end up inside. He is now applying that range to some of the most consequential energy technology challenges in the country, and to the question that has followed him the whole way: not just whether a material works, but whether it can be built.
