【卒業研究に対する考え】
  卒業研究とは,現時点の問題点を見つけ(テーマの選定),その解決方法を探り,アプローチして,その結果を解析して,原因究明や新しい発見,さらに次の方針を立て(実験とその解析),それらを周りへ伝え理解してもらう(研究発表)という一連の流れの中で,考える力,人へ伝える力,人と協調し物事を成し遂げる力をトレーニングする場であると考えています。これは,動物の病気をみつけ,臨床検査により原因を探り,診断と治療プランを立てて飼い主に説明する,という臨床現場での獣医療にも通じるものであり,体系的・論理的にものごとに取り組む力を養う活動であると考えます。このような経験は,卒業後,臨床現場や研究分野のみならず,様々な分野で要求されるものです。したがって,卒業研究には積極的に取り組んで欲しいと考えます。

【学生さんへの願い】
 学生さんには,臨床・研究に関わらず繁殖に関するあらゆることを体験・勉強してもらい,獣医繁殖学のプロになってもらいたいと願っています。牛の臨床に興味のある学生さんには、個体および牛群を診ながら、健康かつ効率の良い生産性を保つ飼養管理を構築するために、飼養者と協働できる獣医師になって欲しいと願っています。

Self introduction

I am interested in the education and research of clinical veterinary medicine (Theriogenology), and I am doing my best every day with the contact with students as a source of energy. After graduate school, I worked as a postdoctoral researcher (2 places in Japan and 1 place overseas), during that time I also experienced part-time work at a veterinary hospital, wildlife research. I have been a lecturer for more than 15 years, graduates from my laboratory have various occupations such as clinical veterinarians for cattle and companion animals, civil servant veterinarian, veterinarians at zoos and aquariums, veterinarians involved in wildlife and environmental conservation, and university teachers. It has been my great asset to be engaged in and share a period of their school days. Based on these experiences, my goal is to spend meaningful time with the students.

Introduction

In dairy and beef cattle production, the management to maintain high reproductive performance is essential. However, in the current reproductive management of cattle, various problems have arisen such as, "difficulty to find estrus that is essential for artificial insemination", "the conception rate of artificial insemination and embryo transfer has not reached a sufficient level" and "occurrence of pregnancy loss after pregnancy establishment". There are many challenges to improve reproductive efficiency.
In laboratory of Theriogeneology, we are conducting research to obtain findings about reproductive physiology that can contribute to improving the reproductive efficiency of cattle. These studies focus on approaching challenges from a physiological perspective such as, "what kind of physiological abnormalities are involved in the reproductive problems of cattle", and "what kind of treatments are effective to the reproductive problems that relate to the physiological disorders", etc. We believe that elucidation of the physiological mechanism is essential for improving the reproductive efficiency of cattle.
Based on this idea, we are conducting the following research with the aim of improving the reproductive efficiency of cattle.
① Ovarian physiology (morphology and function of follicles and corpus luteum) and related reproductive endocrine
② Elucidation of the physiological mechanism involved in the establishment of pregnancy in dairy cows (oviduct and uterine function, immune function, etc.)
③ Research on timed-artificial insemination program
