国際博士人材のキャリア支援に向けた新提案――YU氏が博士論文予備審査を実施

2025年6月11日，北陸先端科学技術大学院大学において，YU Zhenranyi氏の博士論文予備審査が実施された．論文タイトルは「人文社会系国際博士学生のキャリア多様化を支援するサービスメカニズムの研究」であり，日本の大学で学ぶ国際博士学生のキャリア課題に対する，理論的かつ実践的な貢献が示された．

　本研究は，「アカデミアへの過剰な期待（cruel optimism）」や，異文化環境におけるスキル変換の困難性など，国際博士学生特有の課題に焦点を当てる．その上で，感情的支援，トランスファラブルスキルの再構築，およびAI技術の活用という3つの観点から，包括的な支援メカニズムを構築している．

　質的調査として3つの研究が行われ，インタビューを通じて，キャリア選択を阻む心理的・制度的要因や支援ニーズが体系的に抽出された．とりわけ，AIを用いた対話的支援の可能性に着目した点は，サービス科学と高等教育実務を接続する新たな知見といえる．

　本研究は，国際人材のキャリア支援をめぐる政策・実践の在り方に一石を投じる意欲的な試みである．予備審査は無事に合格した．

Supporting International Doctoral Talent through Service Innovation: YU's Pre-Defense at JAIST

On June 11, 2025, YU Zhenranyi conducted her preliminary doctoral defense at the Japan Advanced Institute of Science and Technology (JAIST). Her dissertation, titled “Designing a Career Service Mechanism to Support Career Diversification of International Doctoral Students in the Humanities and Social Sciences in Japan,” presents a theoretically grounded and practically relevant response to critical challenges in international doctoral education.

The study focuses on the struggles many students face, including cruel optimism toward academic careers, difficulties in applying transferable skills in cross-cultural settings, and the lack of emotionally and contextually sensitive support. To address these, YU proposes a three-part framework combining emotional support, skill reframing, and AI-enabled career guidance.

Her research comprises three qualitative investigations, drawing on in-depth interviews with current and former doctoral students. It identifies psychological and institutional barriers while exploring the role of conversational AI in personalized support design.

This work makes a timely and original contribution to the field of service science and offers actionable insights for policy makers and institutions aiming to build inclusive, future-oriented career development services for international doctoral talent. She successfully passed her pre-defense.
