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 2017, he has been the main supervisor of four PhD students who successfully defended their PhD theses in different areas of graphic technology and color image reproduction.
His current research interests include digital halftoning, image reproduction, color reproduction, appearance printing and 3D printing.
Experienced supervisor
Since 2001, Sasan Gooran has been responsible for and involved in different undergraduate courses in Graphic arts, Computer graphics, Numerical methods, Calculus and Linear algebra. His current courses include Graphic arts, Computer graphics, Image reproduction and image quality, Prepress and printing technology, Foundation course in mathematics and Applied transform theory. He has also been the examiner/supervisor of more than 50 M.Sc. theses.
