Phil Pikus, Ph.D. Candidate

My name is Philip Pikus, and I'm an MD/PhD candidate in the Interdisciplinary Program in Neuroscience completing my thesis work in the Rebeck Lab. My work focuses on the acute effects of novel immunotherapies for the treatment of Alzheimer's Disease, and the role of APOE genotype and cerebral amyloid angiopathy in levels of an adverse effect known as ARIA. 

Outside of the lab, I also coach the Georgetown University club ice hockey team.

Isabella Moyer, B.S.

My name is Isabella Moyer, and I am pursuing an M.S. in Integrative Neuroscience through the Interdisciplinary Program in Neuroscience (IPN). I earned my B.S. in Psychology with a Neuroscience focus and a minor in Biology from Penn State University. My research focuses on investigating the mechanisms underlying chemotherapy-induced cognitive impairment.

Fun fact about me: I stood for 46 hours at Penn State’s THON, a dance marathon that raises funds to support children and families impacted by childhood cancer.

Esti Dautaj, B.S.

My name is Esti Dautaj, and I earned my B.S. in Biomedical Sciences at Liberty University. I am now pursuing a Master’s in Neuroscience through the Interdisciplinary Program in Neuroscience (IPN). My research focuses on investigating the molecular interaction of APOE genotype with cancer-therapy induced drugs that contribute to cognitive impairment. 

Fun Fact about me: I was a ballet dancer for almost 12 years.  

Anusha Sindia, B.S.

My name is Anusha Sindia and I graduated from Villanova University with a B.S. in Cognitive and Behavioral Neuroscience. I am now pursuing my M.S. in Integrative Neuroscience at Georgetown University through the Interdisciplinary Program in Neuroscience (IPN). My research focuses on looking at the role of APOE genotype in AD pathology and immunotherapy-induced ARIA.

Fun fact: I studied abroad in London, UK!

Ruby Addie

Ruby Addie is an undergraduate researcher in the Rebeck Lab at Georgetown University, where she is pursuing a degree in Global Health on the pre-medical track. Her research interests center on the biological mechanisms underlying neurodegenerative disease, particularly the interactions between genetics, inflammation, and disease progression. She is especially interested in connecting neuroscience research with her broader interests in medicine, disease prevention, and human health.

Fun fact: she spent two months gaining clinical experience in Mombasa, Kenya, where she worked across several medical specialties and picked up some Swahili along the way.

Tanish Oberoi

Undergraduate Student, Majoring in Psychology 

Minoring in Public Health

Fun Fact: My favorite show is Suits!

Meredith Habstritt

I’m Meredith Habstritt, an undergraduate researcher in the Rebeck Lab pursuing my degree in Neurobiology. I’m passionate about understanding the mechanisms underlying neurodegenerative diseases and how genetic and environmental factors influence disease risk. Through my experiences as a student, volunteer EMT, and research assistant, I enjoy exploring medicine from multiple perspectives and developing a deeper understanding of both patient care and biomedical research.

Fun fact: I love spending time outdoors—I’ve summited Mount Kilimanjaro and once found myself face-to-face with a black bear!

Bailey Villarreal, M.S. 

After completing my undergraduate studies at Virginia Tech, I earned dual degrees in Psychology and Philosophy. Afterward, I attended Georgia State University, where I completed a master’s degree in neurophilosophy, with a thesis titled “The Hard Problem of Consciousness and Neurobiological Naturalism,” mentored by Dr. Sarah F. Brosnan. During my time at Georgia State, I developed an appreciation for approaching philosophical questions about the mind with the scientific rigor of neuroscience. I am now completing a master’s degree in neuroscience at Georgetown and plan to pursue a PhD upon completing my program. My primary research interests are neuro-glial interactions, neurodegenerative disease, retinal degeneration, neuronal dysfunction, synapse formation, cancer biology, and neuroimmunology.

Jackey Farias, M.S.

I'm Jackey, a master's student in the Rebeck lab! I earned my B.S. in neuroscience and psychology and now I'm attending Georgetown for my M.S. in integrative neuroscience, where I was placed in the Rebeck lab. My role here is to look at cerebrovasculature damage with amyloid deposition in immunotherapy treated 5xFAD mice. Fun fact about me: I love making tres leches cake!

Maria Patricia Salinas

My name is Maria Patricia Salinas but I like to go by Paty! I joined Dr. Rebeck’s laboratory in 2025. I am a graduate of Nursing in my country El Salvador C.A, and have a Bachelor’s degree in Christian Theology to serve in the Church in the Hispanic Community. I started working as an animal care technician in 1997 for the Division Of Comparative Medicine (DCM) where I gained experience working with many animal species from rodents, bats, cats, dogs, ferrets, and nonhuman primates. This gave me the opportunity to eventually work in other labs and directly with researchers in the oncology and neuroscience department all here in Georgetown University. I enjoy watching videos of my native country El Salvador with my husband and traveling there as much as possible with him. I also have 2 talented musician sons, who also work in Georgetown, that I am very proud of!
