Research Interests:

I became very interested in the topic of visual hallucinations during my first year of graduate school. I started to have many questions when I first discovered that patients with a neurological disorder (Parkinson’s disease) and an immunodeficiency syndrome (HIV) could develop non-psychotic visual hallucinations. My culture conceptualizes some aspects of these visual phenomena within spiritualism. I have learned, however, that “visions” have a different definition, as well as associated stigma in the United States. From then on, I have oriented my research in understanding visual hallucinations in non-demented Parkinson’s disease patients, as well as to uncover the perceptual and cognitive mechanisms underlying these visual phenomena.


I was born and raised in Carolina and Canóvanas, Puerto Rico. In college, I was accepted to NIMH Career Opportunities in Research (COR) and started working with Dr. Guillermo Bernal on a Randomized Controlled Trial (RCT) comparing Cognitive-Behavioral Therapy and Interpersonal Therapy for the treatment of young adolescents with Major Depressive Disorder. I also had the opportunity to apply to three undergraduate summer internships in the States: (1) University of California – San Diego, (2) Rutgers University, and (3) Boston University. At BU, I worked with Drs. Alice Cronin-Golomb and Yelena Bogdanova on numerical cognition in HIV. I came to the States in 2008 and started to work with Parkinson’s disease patients. I had received clinical training at the Center for Anxiety of Related Disorders, the Memory Clinic at Brigham and Women’s Hospital and Boston VA Medical Center. I also have experience teaching at Boston University’s Metropolitan College.


I love to dance almost anything: salsa, merengue, bachata, reggaeton, hip-hop, and krump. My first talent show was at the age of 7 and I continued dancing in school dance groups until college. In 2011, I started taking salsa classes and performing with Salsa Y Control Dance Company in Boston.
