2010年北京师范大学获得理学博士学位，2015年入选中国科协“青年托举人才”计划，2018-2019年Harvard University生物与演化学系访问学者，生态学系副系主任。主持国家自然科学基金项目3项，国家重点研发计划子课题1项。承担本科生《普通动物学》、《鸟类学》和研究生《系统与进化生物学》等课程。兼任北京动物学会副秘书长，中国动物学会鸟类学分会理事。
■鸟类与病原体的协同演化（co-evolution）：结合野外调查与分子生物学技术，开展中国鸟类血孢子虫多样性及生物地理格局研究，重建鸟类宿主与血孢子虫的协同演化历史，探究环境因素与系统进化过程对宿主-寄生虫关系动态变化的影响。
■鸟类的物种形成模式：利用系统基因组学方法，重建姬鹟属（Ficedula）、锦鸡属（Chrysolophus）和角雉属（Tragopan）中近缘物种的分化历史，探究塑造羽色性二态等表型差异的遗传机制，更深入的理解自然选择和性选择在物种分化中的作用。
