在新冠病毒的研究中,王怡心作為港大微生物學系研究團隊的一員,真切感受到醫學研究的意義。在她負責的研究項目中發現,新冠病毒在人體肺部的複製能力是非典病毒的3.2倍,但新冠肺炎患者的發炎癥狀及免疫系統反應更為緩慢。王怡心感受到發現的樂趣,她表示以前認為基礎研究離生活很遠,也很少主動與家人分享,如今切身體會到科研的價值,以及自己為社會做出的貢獻。

王怡心表示,70%的實驗都會以失敗告終,每天遇到的問題也不盡相同。但這並不影響她的科研之心,她享受每次發現問題帶來的新鮮感。她認為所有解決不了的難題,源自於思維的局限性,總能有方法繞着走過去,尋找問題的突破口。她不斷查閱文獻,與老師以及身邊的同學積極溝通、分享困惑,在查閱和交談之中發現新的靈感,幫助自己從困境尋找新的方向。
