唾液酸隸屬於酸性糖中的一個家族，大量而廣泛的表現在所有脊索動物和部份的細菌。我們實驗室的主要研究目標分為兩方面:

1. 1. 了解唾液酸和其結合蛋白的交互作用如何調控哺乳動物的生理機能。
   2. 利用糖類生物功能的知識，致力於人體健康的提升。

目前我們的研究聚焦在唾液酸結合蛋白家族(Siglecs) ，這類蛋白大多表現在免疫系統。最近我們發現部份Siglecs 的DNA序列多樣性，會影響人類疾病與臨床病徵。現在我們正設法更進一步探究 Siglecs的分子與生理功能，並找出其基因序列多樣性和人類疾病的關聯性。遠程目標是希望應用我們的研究成果。轉而發展出唾液酸相關的疾病診斷與臨床治療方法。
