Sasan Gooran received his M.Sc. degree in Computer Science and Engineering from Linköping University in 1994. Right after the graduation, he started his PhD study in Graphic arts at the Department of Electrical Engineering, Linköping University, where he later received his Licentiate degree in Electrical Engineering in 1998.
"High Quality Frequency Modulated Halftoning"
After his Licentiate defense, he moved to the Department of Science and Technology, Linköping University, where he later received his PhD degree in Media Technology in 2001. His PhD study was mostly focused on digital halftoning, and in his PhD thesis, titled High Quality Frequency Modulated Halftoning, he proposed a number of novel halftoning algorithms to improve the print quality.
One of the main contributions of his PhD study was the development of a color halftoning method that halftoned a color image by halftoning its color separations in a dependent manner. By doing that, it was shown that not only the print quality was improved, but also the ink consumption was reduced.
Flexographic printing
After his PhD defense in March 2001, he became a senior lecturer in Media Technology at the Department of Science and Technology. Besides teaching, he also continued his research in digital halftoning, developing a novel hybrid halftoning, combining two different halftoning methods, which was useful for Flexographic printing. Teaching undergraduate courses and publishing a number of peer-reviewed papers in international journals after his PhD, helped him become an associate professor in Media technology at the Department of Science and Technology in 2007.
Graphic technology and color image reproduction
Between 2009 and 2024, he has served as the main supervisor for seven PhD students, all of whom successfully defended their theses in various areas of graphic technology and color image reproduction and 3D appearance printing and modeling. His current research interests span digital halftoning, image reproduction, image quality, color reproduction, appearance printing, and 3D printing.
Experienced supervisor
Since 2001, Sasan Gooran has been responsible for and actively involved in teaching a variety of undergraduate courses, including Graphic Arts, Computer Graphics, Image Processing, Numerical Methods, Calculus, Linear Algebra, and Applied Transform Theory. His current teaching portfolio includes courses in Graphic Arts, Computer Graphics, Image Processing, Image Reproduction and Quality, and Programming in Python. Additionally, he has supervised or examined more than 50 M.Sc. theses.
