- 主にM5,6の医学科学生に対して、地域医療における消化器内科としての特性を学んでもらう環境づくりを行っている。具体的には、検査・処置に助手として参加したり、カンファランスで主治医としての意見を述べてもらう等、大学病院では難しい実践的な臨床実習を行っている。一般病院で出会う頻度の高いcommon diseaseを実際に経験することで、国家試験対策としても重要な経験を積んでもらう。

■ 研究者からの一言アピール
- C型肝炎の病態について長年研究を行っています。DAA治療により大半の症例が治癒する時代になりましたが、未だごく少数の治療抵抗例が存在し、病態の解析・新規治療法の開発が責務であると考えています。また、院内連携によるC型肝炎新規症例の拾い上げなどにも取り組んでいます。C型肝炎以外にも、特殊な原発性胆汁性胆管炎例など自己免疫性肝疾患の診療・研究にも力を入れており、学会・論文発表を積極的に行っています。医学部出身者以外でも大歓迎です。是非、一緒に研究を行いたいと考えています。ご興味のある方は、お気軽にご連絡ください。
