Teaching and Research Fields
微分積分学および確率論を中心とした教育研究を行っています.

確率論は,我々を取り巻く環境において起こる様々な偶然(不確実)現象を数理的に考察することによって,フェルマとパスカルによるとされる創始以来およそ350年に亘って発展してきました.確率論における基本的な概念である確率過程は,時間と共にランダムに変動する現象をモデル化したもので,ランダムウォークやブラウン運動はその代表です.確率過程に関する数理的研究は,数学のみにとどまらず,工学,物理学,生物学,金融や保険など,極めて広範な領域において応用されており,時空を超えて日々研究が続けられています.
