Being a critical Internet scholar exploring psychosocial implications of new media demanded her to be well versed in diverse disciplines, including social psychology, visual communication, Science and Technology Studies and feminist technoscience, which made my work interdisciplinary in nature. Her current research focuses on: eMental Health; visual representations of non-suicidal self-injury (NSSI); images of pain; critical digital health studies; ethics of online health research, digital health promotion, photo voice.
