Phoebe Matthew

Student, Columbia University

Hi everyone! My name is Phoebe Matthew, and I am a rising sophomore at Columbia University majoring in Neuroscience & Behavior and possibly minoring in Computer Science. My research this summer in the Siegelbaum Lab at the Zuckerman Mind Brain Behavior Institute explores the role of the ventral CA1 excitatory neurons in the hippocampus, which are known to receive signals from the CA2 region that is heavily implicated in social memory, in valence associated social memory. This type of memory is not only the recognition of a familiar individual but also the memory of how that individual made you feel. Social memory is impaired in several neuropsychiatric disorders, and it is essential to understand how the mechanism behind it to inform possible therapeutics. Beyond the lab, I am a volunteer at a local memory care facility through Brain Exercise Initiative, a writer for Grey Matters (campus neuroscience journal), and involved in Columbia Synapse (traumatic brain injury advocacy group). I also recently got certified as an EMT. I am passionate about brain health advocacy/awareness, science communication, and service. In my free time, I enjoy painting, crafting, reading, and playing the ukulele. I would love to meet everyone, so please do not hesitate to reach out!

Neuroscience and Behavior Student, Columbia University

Hello! My name is Tomás Sanabria and I am a rising sophomore at Columbia University from Cali, Colombia. I am majoring in Neuroscience and Behavior on the premedical track and have a strong interest in public health and patient care. This summer, I will be working on The Future of Bioethics, a project led by Dr. Sandra Soo-Jin Lee and her national-multi university team. I am very excited to learn under her direction and contribute to the fight for a future where health sciences research remains ethical and centered on human dignity. At Columbia, I am a member of the Admissions - Global Recruitment Committee, the Neuroscience Society and will be a volunteer at the Gay Health Advocacy Project this upcoming year. I am also involved in the Columbia Ballet Collaborative and CoLab, two awesome contemporary dance clubs that have allowed me to keep exploring my passion for dance, movement, and its capacity to bring people together. Outside the classroom, I love running, reading, and exploring the best restaurants in the city with my friends. I am so excited to be a part of The Laidlaw Scholars Program and learn from my peers! If anyone is interested in talking, collaborating or just wants to say hello, please feel free to email me at ts3766@columbia.edu. 
Eleanor Cao

Student, Columbia University

Hi! My name is Eleanor Cao, and I am a rising sophomore at Columbia University (Columbia College). I am interested in the intersection between political theory and intellectual history, with a special focus on modern Chinese thought and Taiwanese politics. In my first summer as a Laidlaw scholar, I will be probing Chinese political scientist Yan Jiaqi's theory of democracy in the long 1980s (1978-1992). Please chat with me about art & literature, cats, corvids, crochet, figure skating, and more!!
Zahel Nasari

Student, Barnard College

I am currently a junior at Barnard College of Columbia University studying Computational Biology with a minor in Economics. Through my coursework and research experiences, I have developed a strong foundation in data analysis, quantitative modeling, and computational approaches to complex biological and social systems. My background in economics has further shaped how I think about resource allocation, structural inequality, and policy impacts at scale. I am particularly interested in applying data science and computational methods to questions in public health, migration, environmental justice, and global health systems. Much of my work focuses on how large-scale systems, whether healthcare infrastructure, environmental conditions, or social policy, shape health outcomes for marginalized populations. I am especially drawn to research involving spatial analysis, longitudinal datasets, and health data infrastructure, as well as projects that bridge technical analysis with real-world policy and community impact.

Lauren Suh

Student and Research Assistant, Columbia University Irving Medical Center

Hello! My name is Lauren Suh and I am a rising sophomore at Columbia University from San Diego, California. I am majoring in Neuroscience and Behavior on the pre-medical track and plan to minor in Music (I play the flute!). This summer, I will be working at the Columbia University Irving Medical Center under the supervision of Dr. Yousin Suh. My research project delves into ovarian aging, a critical marker of systemic body aging as one of the first organs to exhibit signs of aging. I will be researching whether DNA Helicase B, or HELB, delays or impacts ovarian aging.  I love yoga, running, thrifting, and baking! I am hoping to learn pottery this summer, so please reach out if you would like to join! 
Rinaz Jamal

Undergraduate Student, Columbia University

Hey everyone! My name is Rinaz Jamal, and I'm a rising sophomore at Columbia University majoring in Neuroscience & Behavior. I am passionate about helping individuals with mental health and neurodegenerative disorders feel seen, heard, and supported. This summer, I will be doing research at the Zuckerman Mind Brain Behavior Institute under the supervision of Dr. Franck Polleux. My project aims to understand the activity-dependent regulation of mitochondrial protein expression in parvalbumin-positive interneurons, which are among the first neurons to fail in Alzheimer's disease (AD). I am excited to add to the scholarly conversation around Alzheimer's research by identifying the molecular pathways that would be most valuable to target for drug development in the future. Because PV-INs are among the first neurons to fail in AD, understanding these metabolic pathways and restoring levels of mitochondrial proteins has the potential to improve clinical outcomes much earlier in AD progression than current methods. At Columbia, I am involved as a Scientific Review Editor for Grey Matters, our undergraduate neuroscience journal; Blog Editor for the Journal of Global Health; Conference Committee member and Peer Buddy for Columbia Synapse, which advocates for patients with acquired brain injury; and volunteer with Brain Exercise Initiative, where I visit patients with Alzheimer's disease and dementia at a local assisted living home. I also play flute and piccolo in the Columbia University Orchestra. In my free time, I love to read and explore New York City. Please feel free to reach out; I would love to get to know you all!

Youness Robert-Tahiri

MSocSci Psychology Candidate (Laidlaw Scholars Alumnus), University of Cape Town

Hello! I recently graduated with an Honours Bachelor of Science in Psychology Research from the University of Toronto. I’m passionate about youth mental health and how humour can be used to support resilience after adversity. My Summer 1 research project explored the relationship between childhood adversity, aggression, and self-regulation — deepening my understanding of the psychological impacts of early trauma. In Summer 2, I led a Leadership-in-Action project at SOS Children’s Villages in Cape Town, where I designed and facilitated a comedy-based mental health program for teens. That experience led me to found HaHaHelps — an organization that uses improv comedy to support youth mental health through accessible, community-led workshops. I am currently conducting a feasibility study of the program in South Africa as part of my master’s dissertation in Psychology at the University of Cape Town, with plans to expand to more communities globally.
