Prior to pursuing my Ph.D., I worked across four labs at the University of Arizona and Yale University where I developed my research interests in the mental health of sexual and gender diverse individuals, suicidality, and the unique intersection of these two areas. I also study and work to implement practices of diversity, equity, and inclusion in ambulatory assessment methods and clinical psychological practice.

Outside of research, I work as an extern therapist at Banner EPICenter, serve as the co-chair of the University of Arizona Psychology Department's Student Wellness Committee, and am the graduate advisor for the University of Arizona chapter of the national mental health advocacy organization Active Minds.

Research Interests: 

  • Integrating ambulatory assessment methods to investigate how the psychological adjustment of sexual and gender minority populations is impacted by the unique stressors experienced in their everyday lives.
  • Using naturalistic observation methodology (namely the Electronically Activated Recorder) to explore the role of the family environment in adolescent suicidality.
  • Explore the intersection of these two foci.
