Jennifer has acted both as Defence Counsel and legal representative for victims in complex international criminal cases involving genocide, crimes against humanity, war crimes and sexual violence. For example, she participated in the representation of Hormisdas Nsengimana (acquitted by the ICTR), of victims before the ECCC and of victims of terrorism.
