The Sexual and Gender Identity Institute (SGI) is comprised of professionals who conduct original research on sexual or gender identity and faith to help further our understanding of these complex experiences for individuals, to be a resource to families navigating these experiences; and to be a resource to Christian institutions (e.g., churches, colleges and universities, campgrounds, parachurch ministries, and so on) as they make decisions about these topics and how to best serve others.
The foundational research that shapes SGI today began in 1998 when Dr. Yarhouse began conducting research at Regent University in Virginia Beach, Virginia. That research lab formally became an institute (referred to as the Institute for the Study of Sexual Identity) in 2004. That institute was renamed when it transitioned to Wheaton College in 2019 (The Sexual & Gender Identity Institute or SGI).
