I finished my PhD at Tohoku University in Summer 2016. I am now a postdoc at Lyon Observatory (France). This page is no longer being updated, please see my permanent webpage at

Welcome to my web page, I was an Astronomy PhD and M.Sc student in the Tohoku University Astronomical Institute, Sendai, Japan. I began my education and research there in October 2010 (as a master student) and I was working with Takashi Ichikawa on the morphological evolution of galaxies. You can read more about it in my research. The picture above is taken in the beautiful gardens of Chuson-ji temple, in Hiraizumi town, late November 2013.

Fully reproducible research

The arXiv version 2 of the NoiseChisel paper is a fully reproducible scientific paper. All the scripts and configuration files that were used to generate the numbers and plots in this paper are included along with its source files on arXiv for any scientist to check/modify (they are also available on Gitlab). These numbers are recorded as LaTeX variables, so if the configuration files (or any thing else, for example program versions) are changed, the numbers and plots in the paper change accordingly. See the explanations on Gitlab for more explanation. Other similar attempts (that I know of) are also listed there.

Not on Facebook

Not on Facebook

This banner was added in 2014. I left Facebook in 2011. I agree with the arguments presented in the link of this banner, but I also believe that Facebook or any other type of social webpage is devastating to our personal curiosity, personality and integrity. Such social networks wash out of us what makes each of us a unique person from the inside and erode our ideas and personality to the same common shape in the constant flood of stimuli. In this respect I also oppose those social networks that this webpage suggests. Please see these two nice TED talks by Eli Pariser and Wael Ghonim.

Removed all Google analytics tags from all the pages. Visitor information is being recorderd only with Piwik. Unlike Google Analytics, were Google keeps the visitor data and also has access to them, with Piwik, visitor data is only stored on my own server and only I can acces it. To respect visitor privacy, only the first two bytes of visitor IP is stored. I only record visitor data as an encouragement to continue maintaining this webpage.
