2011年度前期メンバー＆集合写真

2011年度も始まりました。D2の山口です。今年度前期は、15人のメンバー（先生＋スタッフ6人＋学生8人）となりました。というわけで、大気海洋研1階で撮った集合写真。

2010年度送別会

D2になりました山口です。2011年3月31日に、2010年度卒業生の送別会が北千住で開催されました！　今年は、博士課程からは城谷さん、修士課程からは安岡くん、高橋さん、山崎くんの計4人が研究室を卒業して就職しました。

会では、皆から寄せ書き色紙と花束が、横山先生からも記念品が贈られました。挨拶では思わず涙ぐむ人も…。

今後も飲み会やBBQなどに、また顔を出してくださいね！（今回もOBが駆けつけてくれましたし）
