President 2025-2027

Karen Beale, PhD
Maryville College

Dr. Karen Beale has been a member of SSSS since 2012 when she attended her first SSSS conference and she has attended almost every year since. She has served SSSS through various positions including the Continuing Education Committee, the Awards and Grants Committee, and the Nominations and Elections Committee. Karen is currently a Professor of Psychology at Maryville College and has been teaching and doing research at this small, private, religiously affiliated, liberal-arts college in East Tennessee for the last 17 years. This position and location (Bible belt) have given her the unique opportunity to study the connections between religion and sexuality and specifically the predictors and outcomes of sex guilt and shame. Her research is also informed by her various service positions at the college as well as in the local community, including but not limited to, being co-director of the Appalachian College Association Teaching and Learning Summer Institute, serving as President of the Board of Haven House Domestic Violence Shelter, providing consultation for sex educators in the local public schools, leading travel courses studying sexuality in the Netherlands, and teaching personalized, biographical, inclusive sex education in the community. Since obtaining her Ph.D. in Developmental Psychology, she has gained multiple certifications in the field of sexuality, including AASECT certification as a sex educator and she now serves on the AASECT Sex Education Certification Committee. Because she now has a deep understanding of the complicated and conflicting messages people receive in public schools, churches, and homes about sex/sexuality, she is committed to finding ways to getting scientifically based, sex/sexuality education to those who need it, in a way that they can hear it.

Most recently, I’m now serving in a mentorship role in SSSS’ mentor/mentee program that has been coordinated by Shayna Skakoon-Sparquez throughout the pandemic. After shifting institutions, I now have the time to volunteer with SSSS again in a more involved capacity as the treasurer.

Member-At-Large 2022-2024

Karen John, PhD, MS, BS

My name is Dr. Karen John. I am a native New Yorker, born in the Bronx with a deepened sense of family whose roots run deeply across this continent, touching down in the Caribbean, and extending to the shores of Africa, an existence I have yet to explore. Acceptance was modeled for me early on by my great and grandparents despite their clouded journey of non-acceptance. Regardless, my ancestors instilled their beliefs of equality and openness giving me the voice that I now use today. Thus, from a shy and reserved, little girl emerged a voice of humanism. Having been an active second year member of The Society, I began my membership as a student. Upon graduating, I renewed my membership as a professional. Shortly thereafter, I became active members of both the JEDI Committee and most recently the Race/Ethnicity Special Interest Group (SIG). I am an educator, developmental psychology researcher, and humanitarian. My work alongside of education continues to focus on contextualizing the consequences of marginalization and the resulting disparities. My most recent research was rooted within the LGBTQA+ communities with its primary focus being the lesbian population with resiliency and intimacy being primary to my study. Further interests include race, gender, and sexuality in terms of justice, equity, diversity, and inclusion and how that is reflected in society by means of policies and politics. My humanitarian efforts extend beyond the classroom and into the realm of social media in the form of a podcast which discusses such policies and politics as it relates to the past, the present, and the impending consequences of not addressing the latter to create both a humane and inclusive future. The idea being our duty as humans, is to therefore leave this world in a better state than which we found it. It is my intension to do my part to create a portion of the blueprint necessary for achieving this not just for me because I may not experience it, but for all those who come after me.

Member-At-Large 2022-2024

Dennis Li, PhD, MPH
Northwestern University

As an assistant professor at the Northwestern University Institute for Sexual and Gender Minority Health and Wellbeing whose work focuses on translational science and health equity for historically marginalized populations, I have passions and skills that strongly align with the values of SSSS and can contribute to furthering the organization’s mission and goals. I first attended the annual meeting in 2011 on the recommendation of my advisor, a SSSS Past President. Though my career trajectory has taken me back and forth to related fields and organizations in public health, digital health, implementation science, and others, sexuality research has always been an underlying theme of my research. As a graduate student, I worked to reduce teen pregnancy through data-driven advocacy, policy change, and dissemination of evidenced-based sexual health education. In my later training, I focused on adolescent and young sexual minority men, largely around HIV prevention through digital interventions but also topics like community building, sex seeking, and sexual functioning. This interest in adolescent sexual health carries through today, having co-chaired the Adolescent and Young Adult Health Committee in the American Public Health Association MCH Section for over 10 years. Now, my research focuses on the implementation of digital sexual health interventions, with the goal of reducing both the research-to-practice gap and disparities in sexual health outcomes. Another part of my work is to provide technical assistance on implementation science methods to HIV researchers around the US. This experience is a unique strength I would bring to the SSSS Board, as I am well-versed in working with diverse teams; translating, organizing, and aligning complex concepts; thinking about system-level strategies and outcomes; and supporting stakeholders in meeting their objectives. I am enthusiastic to serve SSSS, and I believe my diverse professional background can help broaden the field of sexuality science.

Member-At-Large 2021-2024

Before pursuing her doctoral work, Megan worked as a certified sexual health educator for a variety of settings including Planned Parenthood.
