Clinical Psychology: The intersection of machine learning, health disparities, severe mental illness, and patient-clinician interactions in historically underserved communities.

I was born and raised in the Dominican Republic, where I was exposed to poverty, inequity, and lack of access to adequate mental health care. This early exposure to health disparities motivated me to pursue a mental health career. As an adolescent, I moved to New York. In undergrad, I majored in psychology. After graduating, I moved to Boston, working in various settings, including research labs, hospitals, clinics, and community organizations. 

My experiences in the Dominican Republic, New York, and Boston have shaped my understanding of mental health and the challenges individuals and communities face. At Mason, I am working under the mentorship of Dr. Natasha Tonge. I am committed to engaging my skills, knowledge, and the George Mason community to improve the lives of others and conduct culturally sensitive clinical psychological science. 

Current Research

My primary research projects focus on using AI/ML to address disparities and minority health in severe mental illness.
