研究方向：
這是一張圖片A. 植物分子農場
　 1. 啟動子的選殖：
　啟動子是基因表現的分子開關，位於基因的上游，調控著基因表現的強弱、位置、及時間，一個好的啟動子可用來驅動多種不同的基因表現，因此極具研發潛力。我們的興趣在篩選並設計各式新穎的誘導型啟動子，以應用於農業生物技術。
　 2. 利用植物生產高經濟價值蛋白質：
　利用植物作為化學工廠生產各式醫藥用抗體或工業用酵素，不需廠房的費用、成本低廉、而且植物生產的蛋白質特性與動物細胞相似、也比其他生產系統具有安全 性、加上種子易於儲存運輸、甚至可直接添加使用，因此是近年來生物技術研發的主流之一，我們也朝向將篩選得到的啟動子，應用在高價值蛋白質生產上。
B. 植物功能性基因體
    　植物基因體組的解碼以及生物資訊學的發展加速了功能性基因體學的研究，目前我們應用已經解碼的水稻基因體組，藉由基因轉殖技術大量或抑制特定基因表現、 或使用功能缺失水稻突變體，來研究植物養分吸收的分子機制，以期提高作物養分吸收效率。同時我們也篩選和重金屬吸收、耐受性相關的基因，希望未來能應用於 植生復育（phytoremediation）。
