Judith Martin studies how individuals’ cultural backgrounds influence their communication with and attitudes toward others. She has published more than 70 research articles, essays, and books and received several awards for her research.
Martin investigates what it means to be an effective communicator when interacting with individuals from different cultural groups, in both online and face to face contexts. Her research projects have investigated language and cultural challenges encountered by individuals living in and adapting to new cultural contexts (e.g. business personnel working overseas, international workers/students in the U. S., and U. S. American students studying abroad).
Her more recent work addresses how individuals’ ethnic/racial identities influence their relationships and communication with others. One recent study investigated how the diversity of young people's friendships influenced their views toward racial categorization and also their tendency to enter into intercultural romantic relationships. She is also interested in the impact of online communication on intercultural relationships in various contexts (education, business, health care).
