研究プロジェクト
AI創薬
広大な化合物の「海」からほとんど手がかりなしに目的の化合物を「照らし出す」AI創薬システムLIGHTHOUSE (灯台) を開発 (Shimizu et al., 2022)し、いくつもの新薬を実験的に見つけたことで、NHKなどテレビ各社や朝日・読売新聞、ネットニュースに大きく取り上げられました。
現在はLIGHTHOUSEをさらに拡張させ、物理化学法則を取り込んだ創薬基盤プラットフォームの開発をしています。低分子医薬品だけでなく、中分子・抗体医薬といったより複雑な分子デザインにも挑戦を始めました。
大規模データ時代のシステムワイドな疾患研究
糖尿病やがんなどの多因子疾患では、単独の遺伝子や分子に原因を帰着させることができません。代謝物・タンパク質・RNAなどの多階層のデータを数理科学的に統合することで、多因子疾患の病態の包括的かつ定量的な理解を目指しています。
(Kodama, Oshikawa, Shimizu et al., 2020; Uematsu, Ohno, et al., iScience, 2022など)。
(Kodama, Oshikawa, Shimizu et al., 2020; Uematsu, Ohno, et al., iScience, 2022など)。
AIを使った臨床患者データ解析 (クリニカルインフォマティクス)
医師としての専門的な知見をベースにして、健康・疾患データならではの課題に対処するための解析手法・ツールの開発や、患者さんの層別化に関する研究を行っています。例えば乳がんの遺伝子発現データをAIで学習することで、23の遺伝子のみからTNM分類以上にステージを層別化する手法を開発 (Shimizu et al., 2019) し、NHKニュースや日経新聞で報道されました。

これ以外にもさまざまな研究をしています。ぜひお問い合わせください。
