Charli Sitinjak, holds a PhD in Social Psychology with a strong commitment to addressing social issues, including bullying and cyber harassment. My research encompasses the application of social, environmental, and health psychology to enhance the connections between the built environment, transportation, and overall well-being. I specialize in environmental gerontology and examine how the environment impacts health, including the well-being of older individuals and their experiences with bullying, road safety, giving up driving, and other aspects of later life.
