Project Leaders 

Dr. Ian Holloway

uTECH Principal Investigator


Dr. Holloway, professor of social welfare at UCLA, has spent his career researching how social media and new technologies can promote health and well-being.

Dr. Holloway’s work has focused primarily on gay men’s sex and sexuality. He believes that research by and for gay men has the potential to make an important impact. Technology is a huge part of how many people find friends and meet sex partners. If we can gain insights about ourselves and our sex through the technologies we already use, we can learn about resources that can help make sex safer and more fun.
