Riley O’Neill
She/Her/Hers/ Ella
Riley is a clinical psychology PhD candidate with an emphasis on Health Psychology and Behavioral Medicine. She graduated from the University of Alabama with a Bachelors in Psychology and Spanish. Riley examines how stress and sociocultural contexts contribute to socially driven mechanisms of cardiovascular disease (CVD). Specifically, her research focuses on refining ecologically valid characterizations of stress to clarify its cardiovascular impacts. To support this work, Riley received an NHLBI NRSA Pre-Doctoral Fellowship (1F31HL170513). In her free time, she enjoys upcycling thrifted finds, catching live music, and watching movies.

Amelia Ibarra Mevans
She/Her/Hers/Ella
Amelia is a doctoral student in the University of Arizona’s Clinical Psychology program with a minor in Health Psychology. Her research explores how differences in stress appraisal and sociocultural resilience may contribute to better health outcomes in Hispanic/Latinxs. Specifically, she is interested in studying how stress exposure differs from stress experience in Latinxs, potentially due to sociocultural mechanisms like higher social support and collectivism, leading to lower risk for cardiovascular disease. During her free time, Amelia enjoys hot yoga, cooking, drinking coffee with friends, watching movies at The Loft and chilling at the Cat Café.

Melissa Flores, PhD
She/Her/Hers
Bio
Dr. Flores (she/her) is an assistant professor in the Department of Psychology at the University of Arizona. As an interdisciplinary scientist, her primary focus is understanding the complex interplay of social and structural factors contributing to health disparities within the Latino/x population and other historically excluded groups. Her approach is centered on resilience while employing advanced quantitative methods to model social environments. Her ultimate goal is to establish links between these environments and health outcomes, such as cardiovascular health and disease across the lifespan.
Dr. Flores is also a distinguished National Heart, Lung, and Blood Institute (NHLBI) R00 MOSAIC Fellow. Within her MOSAIC project, she leverages machine learning techniques to optimize cardiovascular risk assessment specifically tailored to the Latino/x communities.
Dr. Flores is dedicated to fostering inclusivity in academia. She actively engages in mentoring activities across various academic disciplines and is committed to strengthening the academic pipeline for scholars from underrepresented backgrounds.

Veronica Kraft, Ph.D.
Bio
Dr. Veronica Kraft is a Postdoctoral Scholar in Health Psychology at the Ohio State University (OSU) under the mentorship of Dr. Joshua M. Smyth. Her primary role is to investigate how dynamic stress responses influence adherence to promotive health behaviors, informing the development of scalable interventions. Her independent research program integrates ecological momentary assessment (EMA), geospatial data, and ambulatory biomarker monitoring to examine how dynamic stress responses unfold in everyday life and whether ecological context, particularly green space exposure, may buffer against cardiovascular health risks in midlife adults.
Prior to joining OSU, Dr. Kraft was a Postdoctoral Research Associate I in the SuRRF lab, where she led a pilot study using EMA and ambulatory monitoring to examine within-person, momentary associations between green space exposure and proximal cardiovascular health indicators and perceived stress. She earned her Ph.D. in Psychology (Cognition and Neural Systems) from the University of Arizona in 2023, where her dissertation examined how early-life and current environmental factors shape stress perception and, in turn, influence reproductive health among Hispanic women in the US and Mexico. When not analyzing data or writing grants and manuscripts, Dr. Kraft enjoys spending time in nature, exploring new coffee shops, and relaxing with her cat, Loki.
