About

I am an evolutionary biologist. My research interests are computing and large-scale data analysis relating to organism’s evolution, so called bioinformatics or phyloinformatics. I studied DNA-based species delimitation and its application to comparative analysis in my PhD. Now, I do virtually anything bioinformatic, from assembly of the next generation genome sequences to phylogenetic inference. Please see Research for details of my research interests.

藤澤知親は進化生物学者です。研究分野は進化に関する大規模データの解析とコンピューティング、いわゆるバイオインフォマティクス/ファイロインフォマティクスと呼ばれる分野です。博士課程ではDNAを用いた種の発見方法とそれらの比較法への応用を学びました。現在は次世代シークエンサデータのアセンブルから系統解析まで、バイオインフォマティックないろいろなことをしています。より詳しい研究内容についてはResearchを見てください。
