Purpose: E-Portfolio is a powerful tool for demonstrating evidence of learning and achievements in graduate research. The purpose of this paper is to examine the concept, structure and functions of e-Portfolio in graduate research and discuss the significance of the role of e-Portfolio in enhancing the quality of graduate research students and their learning environment. Design/methodology/approach: The discussion starts with the concept of e-Portfolio in the context of modern digital technology and innovative educational perspectives, which emphasise critical thinking, social interaction, task-based learning, and independent learning. Findings: It is found that e-Portfolio greatly enhances three important aspects of research students: academic development, research profile and social networking. E-Portfolio empowers research students to take full control of their own learning and research journey. Originality/value: The paper shows that e-Portfolio contributes to the enhancement of educational practices in terms of moving the teaching and learning focus from supervisor-centred to student-centred learning and research, as well as from technological control to technological empowerment.
