専門は惑星科学、惑星物理学、惑星物質・物性科学、惑星探査科学。特に熱赤外カメラを用いた史上初の小惑星探査により、惑星探査に「熱撮像」の手法を世界で初めて導入に成功し、さらに「太陽系物性科学」の分野を創設。観測機器の開発による惑星探査でのその場観測とサンプルリターンによる帰還試料分析を主な研究手法とする。
主要な開発機器は、蛍光X線分光計、熱赤外カメラ、多波長熱赤外カメラである。また開発中のものはマルチターン飛行時間型質量分析計等である。地上分析においてはハイパースペクトル顕微鏡(フランスIAFとの共同)やロックインサーモグラフィ法による熱拡散率顕微鏡(石崎拓也氏と共同)による帰還試料の分析の他、将来の資料熱物性分析のための多色熱赤外顕微鏡の開発を推進中である。

日本機械学会年次大会講演論文集(CD-ROM), 2019 S13211, 2019<p>This report deals with the improvement of wire-sawing performance in vacuum by applying vibration to the saw wire. The performance of wire-sawing in vacuum has been investigated for future lunar and planetary explorations. Nickel fixing abrasives adhered on a rock specimen in vacuum and the abrasives slipped on it. Consequently, the rock was hardly cut. In the prototype for a high normal load, the cutting performance was investigated both in air and vacuum. The cutting amount was linearly increased under a high normal load even in vacuum. On the other hand, it was found that the saw wire vibrated due to fluctuating tension. The vibration of a tool generally accelerates the removal rate. In the previous machine with a flexural roller guide which natural frequency is 1820 Hz, the vibration of the saw wire at a frequency of 2100 Hz was excited to improve the performance. The cutting depth was proportional to the number of strokes even under a low normal load.</p>
