研究方向：

我们是原位结构生物学实验室。关注“细胞建筑学”：各个亚细胞结构是如何搭建成一个具有完整生物学功能的细胞，以及“生物大分子社会学”：细胞内的细胞器、生物大分子之间的相互关系。

原位结构生物学是基于冷冻光电联用（CLEM）、冷冻电子断层扫描（cryo-ET）等技术的新兴结构生物学分支，是一种可以在细胞生理状态下，对生物大分子和亚细胞结构在分子分辨率（1 ~ 10 nm）水平进行原位的结构分析和功能研究的技术手段。我们主要研究方向包括：

1. 在纳米、亚纳米尺度对基础细胞生物学问题的研究。

2. 对包括神经退行性疾病在内的老龄化疾病致病机制的研究。

3. 适用于组织样品的高分辨原位结构生物学方法优化。
