- Education
Electronic
Visualization Laboratory, Dept. of Computer Science, University of
Illinois at Chicago
Ph.D. in Computer Science, August
2003 - present
- Thesis: “Visualcasting: Scalable
Real-Time Image Distribution in Ultra-High Resolution Display
Environments” implemented a high-performance image multicasting service
for scalable heterogeneous tiled displays using high-performance PC
clusters, 10Gbps networking, and various software tools (C++, OpenGL,
SDL, Pthread, TCP/IP and UDP sockets). Visualcasting is based on the
Scalable Adaptive Graphics Environment (SAGE), a scalable graphics
architecture supporting scientific visualization and collaboration on
ultra-high-resolution tiled displays. SAGE Visualcasting has supported
international collaboration among partners in the OptIPuter project (a
major NSF-funded initiative to design advanced cyberinfrastructure for
data-intensive science using optical networks).
- Course Works: GPA 4.0/4.0

Mining and Text Mining
School of Electrical Engineering, Seoul National University, Korea
Master in Electrical Engineering,
March 1997- February 1999
- Thesis: “Hardware-Software
Partitioning and Scheduling for Reconfigurable Architecture” presented
an efficient heuristic algorithm of hardware-software partitioning and
scheduling for embedded system design including run-time reconfigurable
Field Programmable Gate Arrays (FPGA).
B.S. in Electrical Engineering,
March 1993- February 1997
- Research and Work Experience
Electronic Visualization
Laboratory (EVL), University of Illinois at Chicago (Aug 2003 -
present)
Main developer of Scalable
Adaptive Graphics Environment (SAGE):
http://www.evl.uic.edu/cavern/sage
- Designed and implemented SAGE’s high-performance graphics
streaming architecture to support real-time streaming of extremely
high-resolution graphics and video over high-speed networks from remote
clusters to high-resolution tiled displays.
- Developed SAGE’s desktop manager that enables users to run
and interact with multiple visualization applications on a tiled
display and to freely move and resize application windows.
- Extended SAGE to support distance collaboration with multiple
endpoints by implementing Visualcasting.
- Extensive collaboration experience with SAGE project members
at EVL and with international collaborators at University of
California, San Diego, University of Michigan, SARA Computing &
Networking Services in The Netherlands, NTT in Japan, and Korea
Institute of Science and Technology Information (KISTI) in Korea.
Imaging Media Research Center,
Korea Institute of Science and Technology (Nov 2001 - Dec 2002)
- Developed an image processing hardware using a FPGA and DDR
(double-data-rate) RAMs. It pre-processed input images to make them
look correct when projected on a cylindrical screen in an immersive
display environment.

- Professional Activities
“Global Lambda
Visualization Facility”, iGrid 2005:
Demonstrated simultaneous
real-time streaming of a wide variety of high-resolution graphics from
Korea (over KREONet2), The Netherlands (over SURFNet), and Chicago
(over National LambdaRail) to a 100-Megapixel high-resolution tiled
display in San Diego. 10Gb/s was allocated for the demonstration, which
ran for a total of 6 hours over 3 sessions. 9Gb/s of sustained
throughput was achieved.
“Scalable Visualcasting”,
Supercomputing 2006:
Demonstrated inter-booth
collaboration using Visualcasting and tiled displays. Three booths in
the convention joined this demonstration: Calit2/CEOA, SARA/Dutch
consortium, and University of Michigan/Research channel. The
Visualcasting service enabled participants to share their visualization
applications on each other’s tiled displays while seeing each other by
HD camera live feed.
“Collaborative Visualization Architecture in Scalable Adaptive Graphics Environment”,
IBM Visualization and Graphics Student Symposium 2007:
Presentation about the graphics streaming architecture and capabilities of SAGE and Visualcasting.
