Research Interests

My primary research focuses on the characterization of the earliest detectable cognitive deficits in preclinical Alzheimer’s disease (AD). Under the co-mentorship of Dr. Cronin-Golomb and Dr. Yakeel Quiroz (Massachusetts General Hospital,, I am funded by the National Institute of Aging F31 mechanism to investigate working memory and its relationship to in vivo AD brain pathology, task-based functional magnetic resonance imaging (fMRI), and resting-state fMRI in preclinical autosomal dominant AD and sporadic AD.

Current Projects

  • Relationships Between MRI Cortical Thickness, Episodic Memory, and AD brain pathology in Preseninlin1 E280A Autosomal Dominant AD (principal investigator – Dr. Yakeel Quiroz; co-first author – Federico d’Oleire Uquillas, B.A.)
  • Cognitive and Behavioral Profiles of Adolescent Preseninlin1 E280A Mutation Carriers (principal investigator – Dr. Yakeel Quiroz; first author – Arabiye Artola, M.H.S.)
  • Semantic Working Memory Capacity in Healthy Young Spanish-Speaking Adults (principal investigator – Dr. Yakeel Quiroz, co-first author – Dr. Iván García-Magariño)
  • Relationship Between Visual Short-Term Memory Binding and In-Vivo Amyloid-ß in Clinically Normal Older Adults (principal investigators – Drs. Yakeel Quiroz, Reisa Sperling, and Keith Johnson; summer scholar mentee – Alan Marquez)
  • Qualitative Experiences of Individuals with Parkinson’s Disease and their Care-partners (principal investigator – Dr. Alice Cronin-Golomb; project leader – Shraddha Kinger, M.A.

Relevant Experience

As an undergraduate at Texas A&M University, I worked with Dr. Steve Balsis to use Item Response Theory statistical techniques to analyze data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI). My Honors thesis focused on the Alzheimer’s-related sequence of neurodegeneration in sub-regions of the temporal lobe. My later work centered on determining which neuropsychiatric symptoms were most strongly associated with Alzheimer’s-related cognitive decline (Fuller et al., 2019). My senior year, I also joined the lab of Dr. Annmarie MacNamara. In this lab, I gained valuable neuroimaging experience with EEG as we investigated the event-related correlates of cognitive reappraisal techniques toward emotionally salient stimuli in individuals with psychiatric conditions and healthy controls.

For the past two years of my doctoral training I have been part of Dr. Quiroz’s ongoing longitudinal study of the cognitive and biomarker profiles of Preseninlin1 E280A Autosomal Dominant AD. Participants in this study travel from Colombia, South America to Boston for neuroimaging (MRI, PET) at MGH. When participants are in Boston, I and other members of the lab help execute the study procedures, and I specifically commonly administer several computerized cognitive tests.

Hobbies and Interests

During the warm months, I enjoy playing tennis, kayaking, and taking my dog to the Middlesex Fells Reservation. In the winter, I enjoy skiing with family and friends. Attending an SEC west school made me a huge NCAA football fan, but each year you will find that I’ve probably had my heart broken by Texas A&M football. I also play the piano, enjoy taking photographs, playing board games with friends, and watching an eclectic selection of TV shows (Game of Thrones, Madam Secretary, most game shows, the Bachelor/ette).
