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.

Hello there! I'm a history major at Columbia University. I spent 14 years as a border-crossing student, living in mainland China and commuting to Hong Kong every day. I  spent my high school years in Houston, Texas. My primary focus is transnational Asian history, though I am also broadly interested in philosophy, IR, and political theory.  I spent my freshman year at Rice and transferred to Columbia as a sophomore. I'm currently a rising junior.  I speak English, Mandarin, and Cantonese. I am currently unsuccessfully acquiring Japanese and French.

Hi! My name is Celine and I'm an undergraduate at Columbia University studying Economics-Political Science and Hispanic Studies. In addition to these topics, I also enjoy learnings about China-Taiwan history and politics.  A big part of my interests and passions also lie in journalism. I work as a student journalist at the Columbia Daily Spectator, where reporting on university news. I love studying the things I do because the allow me to tell stories and learn about people from across the world, just as journalism allows me to do here at Columbia.  In my free time, I also love cooking, baking, running, listening to music–maybe occasionally singing some karaoke–and spending time with my friends. 

Born and raised in Zimbabwe, Melody Matavire is a prospective Physics and Data Science major with a deep passion for both STEM and social impact. While science and technology shape much of my academic interests, I have also become increasingly aware of the social challenges that continue to affect communities and shape people’s lives in lasting ways. One issue that is especially close to my heart is early teen pregnancy and school dropouts. Growing up, I witnessed how situations like these can alter the trajectory of young people’s futures, particularly for girls whose educational opportunities become limited long before they are able to fully explore their potential. Through the Laidlaw Scholars Programme, I hope to research how comprehensive sexual education can be used as a practical and culturally relevant tool to address early teen pregnancies and reduce school dropout rates.  Beyond academics and research, I enjoy exploring new experiences, asking too many questions, and finding connections between science, society, and everyday life, otherwise you can also find me in the kitchen cooking whilst singing.

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!   

Hi everyone! I'm a rising sophomore majoring in Neuroscience and Behavior. My research at Columbia University Irving Medical Center's Troy Lab investigates how retinal vein occlusion (RVO) — a leading vascular cause of vision loss and blindness — affects the lateral geniculate nucleus, the thalamic structure that relays visual information from the retina to the cortex. RVO is typically treated as a disease of the eye, but vision depends on the entire pathway, and damage at the retina may drive changes deeper in the brain that go unrecognized in current care. I'm interested in characterizing those downstream effects on the LGN and identifying neurological markers that could help explain why some patients lose vision permanently while others recover, ultimately informing earlier intervention before blindness becomes irreversible.  Outside the lab, I love singing a capella with Columbia Sur and exploring the city. I'm excited to meet everyone and please feel free to reach out!
