Modular AI Agents Are Transforming Scientific Research at Harvard

Artificial intelligence continues to evolve rapidly, with multimodal large language models showing remarkable learning and reasoning capabilities. However, scientific research presents unique challenges (uncertainty, adaptation, and expert judgment) that have limited AI’s practical impact in labs. 

Now, Harvard’s John A. Paulson School of Engineering and Applied Sciences (SEAS) is spearheading an initiative to bridge this critical gap and unlock AI’s transformative potential for science.

APEX+: Building Modular, Collaborative AI for Science

Professors Jia Liu and Na Li are leading the Agentic and Physical AI for Excellence in Science and Technology (APEX+) project. Their goal is to create general-purpose AI platforms that operate across disciplines and connect directly with laboratory instruments and robotics.

Unlike conventional monolithic AI models, APEX+ takes inspiration from real scientific work by combining modular AI agents with expert human judgment in an iterative process.

• Each AI agent is designed for specific research tasks, rather than attempting to address entire workflows at once.
  
  
• These agents integrate domain-specific algorithms with the advanced reasoning and planning abilities of large language models.
  
  
• The approach takes queues from how scientists gradually develop understanding, adapt methods, and carefully curate data.

Real-World Impact: Empowering Research Across Fields

Liu and Li have already demonstrated the effectiveness of their modular approach in areas like neural data analysis, large-scale gene expression mapping, and behavioral research. Their AI agents manage complex workflows by blending algorithmic power with human-like decision-making, delivering robust results in diverse scientific domains.

• AI agents can autonomously search literature, adapt algorithms, and synthesize findings much like a human researcher.
  
  
• Modularity ensures flexibility and adaptability, enabling researchers to address evolving scientific questions with greater agility.

Humans and AI: A Collaborative Future

Central to APEX+ is the vision of augmenting, not replacing, human expertise. The initiative emphasizes augmented reality (AR) and virtual reality (VR) interfaces, allowing AI agents to become true partners in the laboratory.

• Prototypes of AR glasses can identify lab equipment, offer real-time guidance, highlight errors, and document procedures seamlessly.
  
  
• These technologies aim to boost transparency, reproducibility, and efficiency, while ensuring researchers remain at the core of discovery.
  
  
• Continuous AI support transforms scientists into enhanced collaborators, providing unprecedented access to information and analysis.

Reshaping AI’s Scientific Role

Scientific inquiry is inherently complex, requiring adaptability and deep domain knowledge. By designing AI systems that mirror the modular, iterative practices of human researchers, APEX+ is setting the stage for seamless AI integration in research workflows. This initiative is about empowering researchers, driving innovation, and establishing new benchmarks for collaboration and reproducibility in science.

Key Takeaway

The future of AI in science rests on flexible, modular systems that support and enhance human expertise. APEX+ is leading the way, promising to revolutionize discovery and reshape how researchers interact with technology in the lab.
