Nadal's book Filipino American Psychology: A Handbook of Theory, Research, and Clinical Practice (Wiley, 2011)[7] was noted for being the first comprehensive book on Filipino American mental health issues.[8][9][10] Nadal has gone on to release other books on this and related topics.[11][12]
Nadal's research and writings concentrate on race, ethnicity, sexual orientation, gender, and the concept of racial microaggressions, and other microaggressions or subtle forms of discrimination towards racial/ethnic minorities, women, and LGBTQ populations.[13] He created and published the Racial and Ethnic Microaggressions Scale in the Journal of Counseling Psychology in 2011.[14] Nadal has also researched "sexual orientation microaggressions"[15] In 2013, Nadal released That's So Gay!' Microaggressions and the Lesbian, Gay, Bisexual, and Transgender Community.[16][17]
Nadal was raised in Fremont, California.[23] During his high school years, Nadal reports being bullied for being gay.[24] Since 2010, he has become vocal about ending bullying in schools.[25]
Nadal has written or spoken about the need for Filipino Americans to address colorism within their families and communities,[26] the need for people to challenge homophobia and transphobia,[27] the experiences of invisibility and marginalization of Filipino Americans and other "brown Asians" in the general Asian American community,[citation needed] the racial microaggressions LGBTQ people of color experience in dating and sexual relationships,[28] the systemic colorblindness and marginalization of people of color in queer studies,[29] as well as anti-black racism.[30]
In 2007, Nadal gained attention with several media outlets when he started an online petition against ABC Studios for negative statements made about Philippine medical schools on the television show Desperate Housewives.[31][32]
In 2014, Nadal formed the LGBTQ Scholars of Color National Network as a way to provide support for LGBTQ people of color in academia.[citation needed]
In 2016, Nadal and his colleagues wrote an open letter to the New York Times for their lack of Filipino American representation in a video segment that described Filipino American experiences.[33][34][35]
Nadal was also very vocal about addressing racism and Islamophobia in response to the Pulse tragedy in Orlando.[36]
In 2017, American Psychologist published Nadal's "Let's Get In Formation": On Becoming a Psychologist-Activist in the 21st Century, where he argued of the ethical responsibility for psychologists to "combat oppression on individual, interpersonal, group, and institutional levels."[37]
