About
Engineer-researcher with a Ph.D.\ from Seoul National
University of Science and Technology (2020,
Information & Communication Media Engineering),
working at the intersection of
digital signal processing,
broadcasting / streaming media,
wireless mesh / disaster communications,
sports performance analytics,
wearable health sensing,
IoT sensor networks, and
computer vision.
Track record across these areas: 16 granted
patents, 6 government-funded R&D
projects, and peer-reviewed publications in
IEEE EMBC, IJASC, and the Korean Society of Broadcast
Engineers (KCI). Doctoral thesis on the design of a
reactive, distributed, microservices framework and its
implementation as a digital signal-processing system.
Currently leading R&D at VENDIT Inc. Personal
research interest: software-defined radio, low-cost
reproducible measurement systems, and turning legacy /
poorly-documented protocols into open code --- see the
recent T-DMB receiver work
(below).
Current R&D focus at VENDIT
Disaster communications for deeply enclosed
spaces. Underground utility tunnels,
construction sites, hospitality facilities --- the
kind of environments where the conventional wireless
coverage collapses on the first concrete wall, and
where in every recent Korean disaster (소공동 화재,
광명 붕괴, 포항 침수, 이천 물류센터 화재) the common
thread has been the same: communication lost, location
unknown, evacuation guidance absent. We are building a
self-healing dual-band wireless mesh
(BLE 2.4 GHz + LoRa 920 MHz) that survives infrastructure
loss, paired with an integrated smart-mask form factor
(toxic-gas sensing, sub-5 m indoor positioning, on-device
AI evacuation guidance). Government-funded R&D,
2026.06 onward, with Prof. Mooyoung Yoo at Daejin
University Department of Architectural Engineering ---
a reunion of the 2017--2019 "safety dream team" whose
MSS Yeonguhmaul work (programme C0505520) produced the
patents KR 10-2034554 and KR 10-2033118 that anchor this
next-generation effort.
Selected open-source projects
End-to-end open-source software receiver for Korean
Terrestrial DMB on low-cost SDR hardware.
Pure-Python pipeline: ETI parsing → Fast Information
Channel decode → Reed-Solomon (204, 188) + Forney
convolutional deinterleaver outer FEC → MPEG-4 SL packet
demux → H.264 elementary stream reconstruction → ffmpeg
decode. Verified on a 30 MB on-air capture of YTN DMB
(channel K8B, 183.008 MHz) with an Airspy Mini and an
indoor antenna: 87.3 % of Reed-Solomon blocks decode
cleanly and ffmpeg renders QVGA H.264 frames containing
recognisable Korean broadcast content.
Papers (preprint + Korean companion) are in the
paper/ directory.
