Session Synopsis

Qi Zhang

The integration of Artificial Intelligence (AI) into chemical sciences is revolutionizing research, development, and industrial processes, significantly enhancing our capabilities in various areas, from material discovery and reaction optimization to process operations and business decision-making. Recently, advances in generative AI have shown great potential in driving substantial breakthroughs in innovation and productivity, transforming workflows and solution strategies for complex problems. However, developing generative AI solutions in chemical engineering and related fields presents unique challenges, including the complexity of modeling chemical systems and the necessity for high-quality, domain-specific data. This session will explore the challenges and opportunities of generative AI, providing insights into how to effectively and responsibly harness its transformative power. In particular, we consider the use of generative modeling, large language models, and AI assistants for property prediction, reaction optimization, molecule/material discovery, process design and optimization, supply chain management, scientific discovery in general (e.g., an AI co-scientist), and enhancing educational outcomes in core chemical engineering courses.

Abstract

Generative AI is quickly becoming a game-changer in chemical processing and manufacturing, offering optimization and predictive tools that go beyond traditional modeling methods. This presentation explores how large language models (LLMs) are being integrated with specialized workflows to tackle complex process data, interpret images for diagnostics, and perform reliability analytics. We will cover methods that use AI-driven representations to increase efficiency in separation processes, speed up root cause analysis, and improve asset reliability through probabilistic modeling, illustrated by real-world case studies from Dow.

Abstract 

Generative modeling is enabling a shift from fitting surrogate models to data to creating models that can design, reason, and explore autonomously. This talk will trace that transformation, beginning with surrogate models and deep learning frameworks that emulate first-principles equations, and moving toward generative models that invert them. I will discuss how approaches such as differentiable programming and generative models enable inverse design, process optimization, and discovery. I will illustrate how generative frameworks can couple with remote laboratories and structured data infrastructures to achieve scientific autonomy, systems that can propose, execute, and learn from experiments. The talk will conclude by considering what this “generative turn” could mean for the future of engineering, where design, simulation, and experimentation increasingly merge into continuous, closed-loop discovery.
