Champer Lab

Welcome! We study gene drive through experiments and simulations.
Jackson Champer is a faculty member at the School of Life Sciences at Peking University and the Peking-Tsinghua Center for Life Sciences. Jackson is also a member of the Center for Bioinformatics.

Gene drive alleles can bias their inheritance to rapidly spread through a population. They can modify the population with a desired trait or even directly suppress the population. The most promising application for gene drives is combating vector-borne diseases, such as malaria and dengue. "Cargos" that could be carried by gene drives to prevent transmission of these diseases already exist. Gene drives could also be used for conservation by removing invasive species or modifying endangered species to protect them. However, substantial challenges must be overcome to develop effective drives.
A primary obstacle to successful gene drive is the formation of resistance alleles by the drive itself. In most organisms, obtaining high efficiency drives is also difficult. Another challenge for gene drives is to spread in only a specific target population, rather than spreading uncontrollably. This could be necessary for a variety of reasons such as sociopolitical considerations or the need to suppress an invasive species only outside its native range. To address these issues, the Champer lab tests gene drive concepts and designs in the model organism, Drosophila melanogaster. There is also research toward generating “release candidates” in mosquitoes.
​A portion of the Champer lab’s research involves computational modeling of gene drives to determine how well they may actually perform in natural populations. Suppression drive and confined drive systems have particularly interesting properties in spatially continuous environments . Modeling is also used to assess drive variants and performance models prior to conducting experiments, which are then used to further refine quantitative mechanistic models.
