Research Interests

My laboratory is interested in understanding how DNA replication is initiated and regulated in eukaryotes. Our focus is on the proteins which direct initiation and are likely to be the target of the cell cycle machinery which ensures that DNA replication is restricted to S-phase and occurs only once per cell cycle. Much of our work involves cell-free extracts from Xenopus eggs that support all the nuclear events of the early embryonic cell cycle and provides a unique system for studying these processes biochemically.
