Jihoon Ryoo Ph.D. Candidate of Computer Science Department Stony Brook University Office: CEWIT 255 Phone: 631.216.7255 Mobile: 631.438.2424 Email: [email protected] INTEREST I am looking for a job where I can do the creative thing. I have experience on “design new thing” and ability to “quickly create working demo”. My 3 years of programming experience at Motorola Solutions and Microsoft Research were mostly in C, C#, Matlab and SQL. I have Electrical Engineering degree in Master and Bachelor, and soon to have Doctoral degree in Computer Science. These experiences and degrees make me possible to understand from the very low level to the high level.
