Hui Sub (David) Shim
Senior Software Engineer, Samsung Electronics Memory Division
I am a PhD student in Electrical Engineering at Stanford University, advised by Professor Philip Levis. My research explores computer systems architecture, with a focus on hardware–software co-design for memory and networking systems.
Before joining Stanford, I spent 9 years at Samsung Electronics in the Memory Division. As a firmware engineer and associate architect, I developed enterprise solid-state drives used worldwide and contributed to landmark products such as the world’s first PCIe Gen5 enterprise SSD and the world’s first 32 TB SAS enterprise SSD.
My professional journey bridges industry and academia. I have worked on high-impact engineering challenges at scale and now study fundamental research questions that aim to shape the future of datacenter efficiency.
