About

Chia-Hung Su is a researcher specializing in electromagnetic interference (EMI) and its intricate relationship with software and system-level design. His work sits at the critical intersection of hardware and software, exploring how seemingly abstract code decisions have tangible electromagnetic consequences. Su’s major contributions include demonstrating that different compilers and optimization options generate machine code that emits significantly different levels of EMI, a finding with profound implications for embedded system design and regulatory compliance. He has also pioneered a measurement-based method to estimate application-specific EMI on devices running time-sharing operating systems, enabling engineers to isolate the electromagnetic "fingerprint" of individual software tasks. To advance the field, Su developed an automated EMI measurement platform integrating a robotic arm with instruments, allowing for precise, repeatable data collection in response to information leakage concerns. With a growing body of work cited in the field of electromagnetic compatibility, Su’s research is essential reading for engineers seeking to design quieter, more secure, and compliant electronic systems.
