Research in my laboratory centers on: (i) the events that occur when the replisome (the multi-component enzyme machine that replicates chromosomal DNA) encounters blockages to replication fork progression, and (ii) the mechanisms by which chromosomes are condensed and separated during cell division. Our studies on the consequences of replication fork blockage and restart utilize purified replication, recombination, and transcription proteins in various well-defined systems reconstituted in vitro that model all steps of these events. Our studies on chromosome condensation and segregation utilize a combination of biochemical, cell biological, and molecular genetic approaches.
