Chinese Military Profiles NUDT Software Reliability Scientist Wang Ji

A profile series by PLA Daily highlights Wang Ji, a senior researcher at the National University of Defense Technology (NUDT) specializing in software reliability and supercomputing verification. Enrolling at NUDT in 1983 at age 13 alongside the launch of China's first 100-million-operation supercomputer (Yinhe-I), Wang spent over four decades developing software testing frameworks for aerospace and military applications. Despite undergoing a high-level amputation following an aortic dissection in 2013, Wang returned to research two years later. The profile underscores state emphasis on secure domestic defense software architecture.

The profile illuminates the development of China's domestic military computing and high-trust software engineering through the story of key researchers at the National University of Defense Technology, underscoring efforts to secure critical software architecture in defense systems.

State media profiles published by PLA Daily have highlighted the decades-long career of Wang Ji, a senior researcher at the College of Computer in the National University of Defense Technology (NUDT). Wang's career underscores Beijing's efforts to build domestic expertise in high-trust software engineering and secure critical computing infrastructure for defense systems. Wang enrolled at NUDT in 1983 before reaching age 14. That same year, the institution unveiled the "Yinhe-I" supercomputer, a milestone machine capable of executing over 100 million operations per second. The breakthrough established China as the third country—following the United States and Japan—capable of independently designing and building giant computing systems. Over subsequent decades, NUDT's research campus evolved into a hub for state computing initiatives, transitioning from the Yinhe series to the Tianhe supercomputing architecture. In 1999, Wang took on software reliability and evaluation assignments for aerospace projects. Working with his research group, Wang developed testing models aimed at verifying code integrity for high-stakes mission software. As China's armed forces accelerated their transition from mechanization to digitalization and informatization, software verification tools became crucial for identifying vulnerabilities before systems were deployed in operational environments. In 2013, Wang suffered an aortic dissection caused by severe overwork, leading to emergency surgery and a high-level amputation. According to PLA Daily reports, Wang returned to his academic and research duties two years after the surgery, focusing on software security and teaching. Official military coverage positions Wang within a broader lineage of NUDT researchers, citing former leaders like Yinhe-I chief designer Ci Yungui and late computer scientist Chen Huawang. The profiles emphasize personal dedication and domestic innovation as central pillars of China's defense modernization and high-performance computing capabilities.
