Chelsea Williams Drives Innovation in Thermoelectric Materials

In a significant move to revolutionize the thermoelectric materials sector, Chelsea Williams has co-founded Mater-AI, a deep-tech start-up focused on harnessing new materials that convert heat into electricity. Williams, who serves as the company’s Chief Technology Officer, emphasizes the gradual evolution of breakthroughs in deep-tech, underscoring that substantial innovations require persistent effort and time.

Williams’ journey began with a passion for mathematics and science, which led her to pursue a degree in physics. After college, she transitioned into quantitative finance, where she applied machine learning principles within investment banking. Despite her success, she felt drawn back to the scientific elements of problem solving. “Around that time, I started exploring quantum computing,” Williams stated in an interview with Silicon Republic. “This was a technology I believed could transform entire industries, which inspired me to pursue a PhD in quantum physics.”

From Finance to Founding a Tech Start-Up

During her PhD studies, Williams participated in venture capital and science fellowships, broadening her understanding of how deep-tech ventures can scale. She discovered that opportunities in this field extend beyond traditional business education, revealing that scientists could also become entrepreneurs. This realization led her to co-found Mater-AI, where she combines her expertise in physics, algorithmic development, and artificial intelligence to tackle complex challenges in materials science.

One of the primary challenges Mater-AI aims to address is the development of thermoelectric materials, which can convert heat into electricity and vice versa. Current materials often have issues, such as toxicity, inefficiency, high costs, and reliance on rare earth metals. “At Mater-AI, we’re developing a physics-informed and AI-accelerated materials discovery engine focused on thermoelectric materials,” Williams explained. “These are maintenance-free materials that can convert waste heat into clean electricity.”

Pioneering Clean Energy Solutions

Mater-AI is on a mission to significantly reduce the time needed for discovering new materials by leveraging data, physics, and predictive models. Williams highlights the vast potential impact, noting that approximately 70% of the world’s energy is lost as waste heat. The company’s technology could help various industries, from manufacturing to data centres, recover some of this lost energy and decrease emissions.

Because Mater-AI’s materials are modular and scalable, they hold promise for creating novel devices tailored to specific industrial needs. Williams believes that their discovery engine could be fine-tuned to identify materials suited for various conditions, including temperature ranges and regulatory requirements. “Over time, our goal is to build a suite of high-performance thermoelectric materials designed for diverse use cases,” she stated, “allowing industries to convert their waste heat into clean energy.”

As the world progresses towards a future where clean energy is the norm, Williams asserts that addressing climate change requires long-term innovation supported by sustained global investment in deep-tech. By merging artificial intelligence with materials science, she believes that significant advancements can be made in the efficiency and commercial viability of materials that recycle lost energy.

Williams emphasizes that these breakthroughs cannot happen overnight. “Real progress will come from a global effort that connects expertise, shares data, and supports breakthrough ideas to achieve real-world impact,” she noted. Her hope is that professionals in the clean tech sector will learn to leverage existing research and technology from the materials science community to create commercially viable solutions for contemporary challenges.

“The potential is there, but we just need to align innovation with specific problems,” she added. Drawing from her curiosity, persistence, and courage, Williams recognizes that while she does not have all the answers, the willingness to challenge conventional limits can foster the creation of new legacies. “I hope my journey demonstrates that it’s possible to combine deep technical work with entrepreneurship and that determination matters more than having all the answers,” she concluded.
