修士論文発表会 & 1/28 〜 2/15 の輪読

今年度から茨城大学大学院農学研究科は従来の 3 専攻から農学専攻の 1 専攻に代わり，その中に 3 つのコースに分かれるという体制になっています．生物制御化学研究室は実践農食科学コースに所属していますが，このコースは従来の資源生物科学専攻と生物生産科学専攻の動物科学専門分野が一緒になったものです．修士論文発表会はコース単位で開催されることになり，今年度は 2/13, 14 の 2 日間で 20 名の学生の発表がありました．生物制御化学研究室からは大垣凱君が「Copalyl diphosphate を中間体とするジテルペンに関する研究」というタイトルで発表を行いました．
