Who Is TM Roh?
Born in 1968, Tae-Moon Roh has been one of Samsung’s most impactful engineering leaders. After earning his B.A. in Electrical Engineering from Yonsei University in 1991, he completed both his M.S. (1993) and Ph.D. (1997) in Electrical Engineering at the Pohang University of Science and Technology.
Over more than two decades at Samsung, Roh built a reputation as a meticulous engineer and a driving force behind the Galaxy smartphone lineup. He played a key role in shaping Samsung’s flagship devices as a development specialist and has long been recognized internally for his hands-on approach to innovation.
Under his leadership, Samsung successfully launched and expanded its foldable smartphone line — a category he championed early on. His strong conviction in foldable form factors helped position the Galaxy Z Fold and Galaxy Z Flip series as the industry standard for premium foldable devices.
Roh’s new role as co-CEO marks a strategic step for Samsung as it focuses on accelerating innovation, strengthening device ecosystems and expanding its leadership in emerging technology categories.
