Biography

Tanuj's research interests broadly lie in the field of Process Systems Engineering with a strong focus on multi-scale modeling and optimization of chemical processes. During his Ph.D., he investigated suitable reformulations to accelerate deterministic global optimization of mixed-integer nonlinear programs. Prior to joining MERL, he was a postdoctoral researcher at TU Delft focusing on integrating physics in machine learning surrogate models to accelerate the solution of nonlinear optimization problems.

- TALK [MERL Seminar Series 2026] Artur Schweidtmann presents talk titled Transforming Process Engineering with generative AI
  Date & Time: Wednesday, September 30, 2026; 11:00 AM
  Speaker: Artur Schweidtmann, Delft University of Technology
  MERL Host: Tanuj Karia
  Research Areas: Artificial Intelligence, Machine Learning
  Abstract
  - Generative Artificial Intelligence (GenAI) has achieved groundbreaking success in domains like computer vision and strategy games, often surpassing human performance. However, its adoption in the process industries remains limited despite immense potential. This presentation focuses on developing GenAI for process engineering. It begins by introducing an AI software tool for digitizing legacy flowsheets, including Process Flow Diagrams (PFDs) and Piping and Instrumentation Diagrams (P&IDs) (https://www.digitization-companion.com). Then, I will highlight innovative AI-driven solutions tailored to process engineering and operations, such as P&ID autocompletion, automated PFD-to-P&ID translation, P&ID error correction, and AI-assisted HAZOPs. The presentation concludes with real-world examples drawn from collaborative research projects with industry partners, showcasing the practical impact of these advancements.
