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. 

Hello! I’m a psychology researcher and the founder of HaHaHelps, a comedy-based psychosocial programme designed to support young people in residential care. I am currently completing an MSocSci in Psychology at the University of Cape Town, where my dissertation examines the feasibility of HaHaHelps with adolescents in South African child and youth care centres. My broader interests include youth mental health, psychosocial intervention development, implementation, participatory approaches, and the use of humour and play to support connection, emotional expression, self-efficacy, and coping with uncertainty. HaHaHelps grew out of my Laidlaw Leadership-in-Action project at SOS Children’s Villages in Cape Town, where I designed and facilitated an improv-comedy programme for adolescents. Since then, I have continued developing and delivering the programme with young people in residential care and am now studying how it can be refined, evaluated, and ultimately adapted for use in other communities and settings. Before this, my Laidlaw research at the University of Toronto examined relationships between childhood adversity, aggression, and self-regulation. I’d love to connect with other Laidlaw Scholars and alumni interested in youth mental health, social impact, intervention development, social entrepreneurship, or simply finding creative ways to turn research into something useful in the world.

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! My name is Izzy and I am a rising sophomore at Columbia University studying Neuroscience and Behavior on a pre-medical track, aspiring to become an emergency room physician or trauma surgeon in the future. Within the last year, I earned my EMT certification and have been involved in various clubs and volunteer activities on and off campus, but am definitely looking for more ways to help the community! I am very excited to be a part of the Laidlaw program and spend the summer in New York. Out of school, I love playing soccer, listening to music, and trying new foods/drinks around the city :) Please reach out if you have any interest/advice for my research this summer or if you just want to make a new friend!

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! 

Hey everyone! My name is Karthik Mahakala, and I am a rising Sophomore studying Environmental Biology at Columbia College. Specifically, I am extremely passionate about environmental health sciences, which encompasses how physical, chemical, and biological factors in the natural and built environments impact public health.  This summer, I will be evaluating the reliability of consumer-facing packaging signals for skin-lightening products across Northern Manhattan as a research assistant in the Llanos Lab.

Hi there! My name is Lydia, and I'm an incoming sophomore at Columbia University studying Human Rights and Public Health. I'm originally from Tanzania. In my free time, I like reading, drawing, hanging out with my friends, and trying out new restaurants in New York City! 

Hello! My name is Abril Rodriguez Calle, and I am a student at Columbia University studying Medical Humanities with the goal of eventually becoming a doctor. My interests lie in the intersection between medicine, the healthcare system, and ethics, especially in understanding how healthcare decisions and policies affect both patients and communities. This summer, I will be working with Dr. Sandra Lee on an NIH-funded research project exploring the ethical, legal, and social dimensions of global genomics research partnerships. The project examines how institutions and communities negotiate issues such as data ownership, privacy, benefit-sharing, and decision-making in genomics research, with the goal of creating a practical “negotiation playbook” to support more meaningful and equitable collaboration. As part of the research team, I will help analyze policies and institutional practices while gaining experience in qualitative research, bioethics, and global health policy.

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.

Hello! My name is Claire, and I am an incoming sophomore at Columbia University from Los Angeles, California studying Medical Humanities and Public Health on the pre-med track. Some of my academic interests include metacognition, writing, and health equity from an educational and technical perspective. This summer, I am conducting eye-tracking chemistry education research, analyzing how learners approach challenging questions and developing an AI tutor that can encourage more effective problem-solving strategies across a broad demographic.  In my free time, I love dancing, running, reading and trying new places to eat around New York. Feel free to reach out to talk research or to just say hello!

I am an undergraduate at Columbia University studying Sustainable Development and Political Science, with interests in energy policy, circular economy, and enviornmental diplomacy. My background combines advocacy, policy, and scholarship, and my research builds on this by examining nationwide legislative frameworks central to the AI revolution and the rapid expansion of data centers. 

Hi! My name is Eleanor Cao, and I am a 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 probed Chinese political scientist Yan Jiaqi's theory of democracy in the long 1980s (1978-1992). I love art & literature, cats, corvids, crochet, figure skating, and more! Please feel free to chat with me--I would love to get to know you all!

Hello! My name is Nadine, and I am a second-year Genetics student at the University of Leeds. I am interested in pursuing a career in research and global health, with a particular focus on cardiovascular science and immunology. I am passionate about addressing pressing global health challenges through impactful solutions that improve the diagnosis, treatment, and prevention of disease. I strongly believe that healthcare should be accessible to all communities worldwide, and I am committed to contributing to this goal. Through my leadership and medical communications experience, I have developed strong interpersonal and organizational skills, and I am now eager to expand into more lab-based roles where I can contribute directly to improving patient care and advancing scientific research. This summer, I will be joining a research team at the Leeds Institute of Cardiovascular and Metabolic Medicine, where we will investigate a novel molecular pathway involved in the progression of cardiovascular disease in individuals with insulin resistance. This opportunity will allow me to deepen my understanding of translational research and its potential to improve health outcomes. Although still early in my journey, I am excited to begin my Leadership-in-Action project and explore how meaningful research can be applied to real-world health challenges. The Middle East faces a particularly high incidence of cardiovascular disease, with heart disease accounting for approximately one in three deaths annually and occurring, on average, at least a decade earlier than in many Western countries. As a Laidlaw Scholar, I hope to use my platform to contribute to tackling this growing crisis and promoting more equitable global healthcare outcomes.

Hello! My name is Van Muller and I am a sophomore in Columbia College from Atlanta, Georgia. I intend on majoring in both Classics and Political Science on the Reception and American Politics/Theory tracks respectively. My project this summer analyzes the debates that formed the United States Constitution through the lens of Classical allusion and aims to evaluate the extent to which those allusions informed the founders about methods of good government.

Hello! My name is Christian Rebolledo, a rising sophomore in Columbia College at Columbia University studying Political Science and Medical Humanities with a Special Concentration in Public Health. I am passionate about intersecting the worlds of public health with political advocacy: people are social, and thus political. I am passionate about community building, civic engagement, and building systems for the next generation of leaders across disciplines. For my first summer as a Laidlaw scholar in the 2026 cohort, I will be characterizing postmortem data from ICE detention centers to identify trends across factors relatd to social determinants of health. I look forward to uncovering the quantitative facets of qualitative reporting currently populating the literature on carceral justice and public health.
