This study delves into emic perceptions of Chinese international doctoral students' navigation of a disrupted study trajectory during the 2019 coronavirus pandemic. Drawing on semi-structured interviews with students and the conceptual framework of bioecological systems theory and needs-response agency, the article reveals a nuanced picture of how activities, relations and roles nested in a PhD study trajectory are impacted by and respond to the crisis. Specifically, the pandemic has instigated a ripple effect upon PhD study that is embedded within a complex system of person-environment factors in the microsystem, mesosystem, exosystem and macrosystem. Confronting these changes and challenges, the students enact needs-response agency to cope with these impacts so as to restore stability. The study concludes with some practical implications for related stakeholders in the bioecological system to generate conditions and support for students to harness possibilities for growth amidst and beyond the health crisis.
