In a recent interview with the Financial Times, Christopher Bishop, head of Microsoft’s AI for Science research unit, discussed the role of artificial intelligence in accelerating scientific discovery. Based in Cambridge, the lab, established in 2022, focuses on applying AI to the natural sciences, including chemistry, physics, biology, and astronomy. Bishop, with a 35-year career that spans physics and neural networks, views this initiative as a significant opportunity to enhance research in fields critical to human progress.

Origins and Purpose of the AI for Science Lab
The AI for Science lab was formed by consolidating various AI-related projects within Microsoft Research. Bishop explained that before its creation, the company had been exploring AI applications in science through separate efforts. Recognizing the potential of deep learning, he proposed uniting these projects into a single unit, augmented by new hires, to centralize and expand the work. “The mission of the lab is to accelerate scientific discovery with AI by science within the natural sciences,” Bishop told Financial Times AI editor Madhumita Murgia, emphasizing its focus on addressing challenges like drug discovery, sustainable energy, and climate change.
Microsoft’s commitment to this effort reflects its strategy to leverage its AI expertise for broader societal impact. Bishop noted that the lab’s work supports the company’s goal of providing tools to researchers and organizations globally, enhancing their ability to tackle complex problems.

A Career Transition from Physics to AI
Bishop’s leadership of the lab stems from a long-standing interest in intelligence, both human and artificial. Initially a theoretical physicist studying plasma physics for fusion energy, he shifted to AI 35 years ago, drawn to the emerging field of neural networks. This move, he acknowledged, was unconventional at the time, as neural networks—then termed connectionism—lacked mainstream acceptance in physics or computer science. Influenced by figures like Geoffrey Hinton, who won the 2024 Nobel Prize in Physics for AI-related work, Bishop saw neural networks as a viable path to understanding intelligence.
He described this career change as a significant risk that later proved fruitful. “When I look back, I must have been very courageous”, he said, reflecting on how the field’s development has since aligned with his early interests.

Key Developments in AI’s Evolution
Bishop outlined three distinct phases in AI’s history. The first involved early enthusiasm for neural networks, driven by researchers like Hinton. He contributed by framing these systems as complex statistical tools. However, their limited performance led to a second phase of reduced interest, as other methods gained prominence. The third phase began around 2012 with the rise of deep learning, which enabled training of multi-layered networks, significantly improving their capabilities in areas like computer vision and speech recognition.
A notable personal experience for Bishop was his early access to Open AI’s GPT-4 in 2023. He found its ability to reason and generate human-like language a marked improvement over previous models. “It was like the hairs on the back of my neck standing up”, he recalled, comparing it to the Wright brothers’ first flight—a modest but transformative milestone.

Practical Applications in Scientific Research
The AI for Science lab is producing concrete results. In drug discovery, AI is used to explore vast molecular spaces—estimated at 10^60 possibilities—to identify viable candidates. One example is TamGen, a molecular generator that developed a potential tuberculosis drug 100 times more effective at binding to its target than earlier compounds. Trained on molecular data, TamGen demonstrates how AI can streamline the experimental process.
The lab also applies AI to materials science, weather forecasting, and climate solutions. AI-driven emulators, which simulate physical systems, are improving weather predictions by processing large datasets efficiently. Bishop referred to this as a “fifth paradigm” of science, integrating computation with traditional research methods.

Microsoft’s Investment in Scientific Progress
Microsoft’s focus on science leverages its extensive AI infrastructure and aligns with its mission to support external researchers. Bishop highlighted potential applications in battery design, carbon capture, and other areas, noting that the company aims to develop tools that benefit a wide range of partners and customers. This approach positions Microsoft to contribute to global scientific efforts while reinforcing its technological leadership.
Looking Ahead: AI’s Role in Science
Bishop anticipates notable advancements in the next two to five years, particularly through AI emulators applied across scientific fields. He acknowledged the current reliance on scaling computational power and data but suggested that alternative methods could emerge. Drawing on AI’s history of adaptation, he expressed confidence in the field’s ability to evolve, citing innovations like TamGen as evidence of ongoing progress.
