Biography

Eric Choi is team leader of the Instrument Development Lab team in PNNL’s Environmental Molecular Sciences Division and the Environmental Molecular Sciences Laboratory (EMSL) user program. They are a team of engineers, researchers, and technicians, developing novel, cutting-edge software and hardware tools and systems supporting EMSL research. Choi works on both hardware and software development for IDL, while also managing the rest of his team. His primary expertise is in electrical engineering and computer science, involving embedded programming, field programmable gate arrays (FPGAs), user interfaces, digital signal processors (DSPs), printed circuit boards, and analog and digital circuit design. He focuses on multiple projects involving FPGAs, DSPs, and microcontrollers throughout PNNL and EMSL. These projects involve creating a user interface to interact with hardware, making it a simple process to use the hardware’s complete functionality.  

Choi has recently worked on integrating his intellectual property, SerialTap, into facility infrastructure to help monitor and analyze serial communication for vulnerabilities and errors. He also helped with development of Cymbiote, a multi-source sensor fusion platform. His efforts contributed to design the sensor board and its embedded programming. With the Juvenile Salmon Acoustic Tracking System (JSATS), another project involving FPGAs, DSPs, and microcontrollers—the system captures acoustic signals in water and converts them to digital signals for analysis. Choi monitors analog signals converted to digital signals and checks for possible salmon acoustic tags. Based on captured information, saved files are analyzed for possible tags, hereby tracking salmon through dams. He is also utilized as a subject matter expert in electrical engineering to help evaluate, design, and integrate different hardware to improve vulnerable cybersecurity situations.
