主要研究领域：
DNA甲基化是直接发生在DNA分子上的一种共价修饰，它直接影响了基因组的构象，是基因表达的一种重要调控方式。高度甲基化的DNA往往被组蛋白紧密包裹而处于封闭状态。去甲基化过程导致DNA双链处于放松状态，并可与转录因子结合从而促进基因的表达。正常细胞分化、组织发育以及疾病包括癌症发生发展过程中常伴随着DNA甲基化水平的改变。本项目组前期工作可以分以下四个方向：1）Alu重复序列甲基化分析技术的发展及应用；2）DNA甲基化模式分析法及应用；3）基因组及表观基因组多态性研究； 4）系统生物学及大规模数据库的整合和应用。
本项目组远期目标是在增强对肿瘤发生发展的理解基础上能够提供有效的预防，诊断及治疗手段。在近期内，本项目组的主要研究方向集中于：1）高通量测序相关技术革新及应用； 2）计算生物学及生物信息学在组学（omics）领域的应用。
