Research Assistant Professor

I am a pharmacist with a Ph.D. in Pharmaceutical Sciences. My research has been dedicated to developing and applying bioanalytical methods for studying biomarkers in various biological fluids. Currently, my work focuses on the evaluation of plasma biomarkers in clinical settings and how these biomarkers can be used to diagnose and monitor individuals at risk of dementia. Furthermore, I’m also evaluating how plasma biomarker levels vary across different populations.

Postdoctoral Associate

I am a geriatrician interested in studying healthy brain aging and dementia prevention. I have worked with stroke rehabilitation, neuroimaging, and cognitive training. These helped me understand the potential of neural repair and neuroplasticity in modulating brain functions towards healthy trajectories. Currently, as a post-doc in the Pascoal lab, I am keen to harness the power of advanced Alzheimer’s disease biomarkers. I want to use both fluid and molecular imaging markers to study the early impact of dementing pathologies on brain structure and function with a goal to thwart such deleterious effects.

Postdoctoral Associate

I am a Biomedical scientist by training with a master’s degree in immunology from the Federal University of Bahia, Brazil (focusing on phytopharmacology and reactive astrogliosis modulation). My Ph.D. is scaffolded in pharmacogenomics and drug-repurposing strategies in progressive Multiple sclerosis animal models and its role over white-matter reactive astrocytes and disease outcomes. This part of my research training was developed at the University Clinic of Duesseldorf-Heinrich Heine University, Germany. After concluding my Ph.D., I worked in the biotech industry as a scientific advisor in synthetic biology strategies for research and diagnostics in neuroscience. I joined Dr. Tharick Pascoal’s lab at the University of Pittsburgh as a postdoctoral research associate directing research on the impact of reactive astrogliosis in the AD continuum. In my spare time, I like a good stroll with a sunset completing the view and some Jazz and good Rap on my earphones.Some weight lifting and good food do a fair job for my daily-basis enjoyment.

Postdoctoral Associate

I am a neuroscience researcher, and I received my Ph.D. degree from University of Calcutta, India. During my Ph.D. tenure, I investigated astrocytes, the most prevalent brain glial cells, to understand their impact on neuron health in Alzheimer’s disease condition. I have two previous postdoctoral trainings at the University of Pittsburgh during which I worked on several mice model systems to decipher the molecular basis of traumatic brain injury, Huntington disease, neuroinflammation etc. I joined Pascoal lab as a postdoctoral associate and I am working on how glial cells either positively or negatively are associated with human Alzheimer’s disease pathophysiology leveraging RNA sequencing information.  I like art, photography, traveling, soulful music and in general I like to enhance my knowledge on anything that is aesthetically valuable and closer to life.

Alumni

PhD Student

During my doctoral studies in neuroscience at McGill University, I joined Dr. Pascoal’s laboratory for a one-year exchange (2021-2022). This experience significantly deepened my understanding of Positron Emission Tomography methodology and enhanced my understanding of the unique characteristics of various tracers. Additionally, it provided the opportunity to collaborate more closely with Suzanne Baker at Lawrence Berkeley National Laboratory (Berkeley, CA, USA), where I subsequently joined as a postdoctoral scholar in November 2023. The mentorship of Dr. Pascoal during these formative years played a pivotal role in my scientific growth and my career! Outside of the lab I enjoy cooking & baking, especially exploring recipes from diverse cultural backgrounds! Additionally, I love attending concerts and soaking in nature by going on hikes!
