第四紀学会に参加しました

こんにちは！修士2年の安東です。前回も学会の話でブログを執筆しましたが、今回も学会の内容でブログを書きたいと思います。

8月31日から9月4日にかけて早稲田大学所沢キャンパスで行われた日本第四紀学会2023年大会に参加してきました。私たちの研究室からはD2佳さん、常岡さん、D1根本くん、M2安東阪本が参加しました！所沢キャンパスは駅から遠くてバスを逃すと到達不可能だったのでちょっと大変でした。ちなみに私は悪い子なのでコアタイムに遅刻しそうになって、タクシー課金しました。みなさんは余裕を持って学会会場にいきましょう。阪本は駅で降りた後にバス停を間違えてバスを逃したそうです。根本はバスを逃して30分くらいPCを背負って走ったそうです。ちなみに当日の所沢市の最高気温は33.5℃でした。熱中症には気をつけて欲しいものです。

安東はポスター発表をがんばりました。横山研内での発表だと細かい議論を詰めるのに気がいってしまうのですが、学会にでるとよりイントロダクションのところを丁寧に説明する必要があるな、と思い、とても勉強になりました。今後の学会でも気をつけたいと思います。

懇親会で学生発表賞がありました。口頭の優秀学生発表賞はななんと佳さんでした🎉ポスターの優秀学生発表賞はななんと私でした🎉嬉しいです！みなさんありがとうございます。今後も精進します。

発表賞の副賞のクマちゃんです！

受賞している佳さんです！
