Welcome to my online space! I am Mahfuz. I was born in Bangladesh. After finishing high school, I went to the Bangladesh University of Engineering and Technology. During my 1st year, I obtained a Monbukagakusho scholarship from Japan government to pursue my undergraduate study in Japan. I left my university and came to Japan in April 2003. Since then, I have been living in Japan. I received my B.S., M.S., and Ph.D. all from Kyoto University, Kyoto, Japan, in 2009, 2011, and 2014, respectively. Currently, I am a Junior Associate Professor at the Department of Electrical Engineering, Kyoto University. I am married and have two daughters. I like to read books, do gardening, play chess, play cricket, and travel in my leisure time.

I enjoy discussing philosophy and eager to know the great stories of humankind. I believe that most humans in this world are good and decent people with good hearts. I also think that we are all connected together. Humans are one big family where every bit of happiness and suffering affects us one way or another.

In my research, I want to develop original ideas and new interpretations rather than increase papers. I want to work with bright students who can enjoy their own development during the research process. I encourage students to become independent and apply themselves fully. I emphasize developing writing abilities, communication and presentation skills, and thinking out of the box in my group. It is challenging to do something different from others. It may take some time, but in the end, it is so fulfilling and satisfying. If you are interested in joining my group or doing collaborative research, contact me personally.
