Compressing the Validation Bottleneck: An Agentic Self-Driving Lab for Scientific Discovery
For researchers using self-driving labs, this work addresses the physical bottlenecks of high experimental cost and low efficiency, though the results are preliminary and domain-specific.
The paper introduces an agentic self-driving lab that reduces both the number of experimental trials (via prior-aware DOE) and the cost per experiment (via cost-aware surrogate predictions), aiming to accelerate scientific discovery in biology and materials science.
Agentic AI-for-Science can automate ideation, planning, and analysis, but final validation still depends on real experiments. A self-driving lab (SDL) can execute those experiments, yet the loop still has bottlenecks: the agent may spend too many rounds on low-value experiments, or each round may require a high-cost experiment. We target these two physical bottlenecks with one agent. First, a prior-aware agentic DOE loop uses domain knowledge and past results to propose feasible and informative next experiments, reducing trials-to-target. Second, a cost-aware surrogate agent predicts high-cost, high-resolution measurements from low-cost, low-resolution measurements. It chooses between a high- and a low-cost measurement based on the predicted uncertainty. We examine these directions in the biology and materials domains, respectively. Together, under a single agent, these components aim to accelerate the SDL loop by reducing both the number of loops and the cost per experiment.
