Last fall, students filed into Vilas Hall for the first session of Online Communication and Personal Relationships, a class with the potential to improve their friendships and family relationships. Her field of expertise is the science of online communication — how people relate to one another when interacting via technology. Toma is internationally known as an expert in online communications in dating, technological interference in relationships, and the impact of social media on human well-being — topics that are a big draw for students. How do we take a full, complicated person and make them into a profile to send to other online daters or to people on social media?” Toma has a very light public social media footprint and jokes that she is mostly a lurker, observing others.
