... After my PhD in 2014, I was offered a research position in Equipment Academy in Beijing, China. (see more)






I completed my PhD research at Instituto de Telecomunicações from November 2011 to October 2013, and was supervised by Professor José M. Bioucas-Dias. I spent the two years studying the topic of interferometric phase estimation via sparse coding in the complex domain. During this period, I addressed interferometric phase image estimation problem. The new sparse-coding-based approach to interferometric phase estimation, termed the SpInPHASE, was proposed with the help of Professor Bioucas. I also attended two courses in IT, “Inverse Problems in Imaging” by Professor Bioucas and “Nonlinear Optimization” by Professor João Xavier.

With the supervision of Bioucas, IT provided me the chance to learn much more beyond my research. I also got the meticulous scholarship from Bioucas and the conditions to enter the research field of interferometric phase image estimation during my studies.

After my PhD in 2014, I was offered a research position in Equipment Academy in Beijing, China. I continued my research in phase denoising by the complex valued dictionary learned from the group sparsity vectors and the research of training multiresolution complex valued dictionaries. Actually, all of my research now is based on my gains in IT. No words can express my grateful thanks to IT.
