Ensuring a Future With Clean Water

Pengkun Liu was highlighted by NSF’s ACCESS program for creating a virtual water treatment plant using PSC’s Bridges‑2 supercomputer. His simulation enables risk‑free testing of scenarios—from emergencies to equipment upgrades—preserving senior engineers’ expertise and speeding up trainee education. “We rely on powerful GPUs for both VR rendering and AI model training,” Liu notes. This work advances digital‑twin and AI methods for sustainable water infrastructure management.

Human-AI Know-How Share for H2O Treatment

Pengkun Liu leveraged PSC’s Bridges‑2 GPUs to build a virtual water‑treatment plant that learns from veteran engineers’ responses to simulated breakdowns. His AI achieved a 0.712 recall in fault identification (versus 0.851 for experts), and together human‑AI recall rose to 0.885. Next, Liu plans to use this VR environment to train new engineers, creating a scalable human‑AI co‑learning system for sustainable water infrastructure.
