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. 

As a first-generation college student, the daughter of Mexican immigrants, and a member of the Otomí Indigenous community, I have found that my experiences have shaped my commitment to advancing educational opportunity and equity. Growing up in rural Maryland's Eastern Shore and navigating the public education system exposed me to the challenges many students in rural and underserved communities face, while also demonstrating the transformative power of education. I am a student at Cornell University pursuing a B.S. in Public Policy through the Jeb E. Brooks School of Public Policy, with minors in Education, Inequality Studies, and Latino Studies. My academic and professional interests center on education policy, with a particular focus on improving educational outcomes and expanding access for rural and Indigenous students. I firmly believe that education is a fundamental human right and that every student deserves access to affordable, high-quality K–12 education, regardless of their background, geography, or socioeconomic status. I am always eager to connect with individuals and organizations working to advance educational equity and opportunity. Feel free to reach out at lm953@cornell.edu.

I am a second-year Politics and Economics student at the London School of Economics and Political Science (LSE), with a strong interest in social investment, sustainable finance and impact investing. During my Leadership in Action placement at City Bridge Foundation, I hope to develop my research, analytical and communication skills while learning how investment can create positive social impact. I also enjoy meeting new people and learning from professionals across different sectors.

Hello! I’m Vardan Umbreyan, a Politics and International Relations student at Durham University and a Laidlaw Scholar. My academic interests lie at the intersection of peace and conflict studies, diplomacy, European governance, humanitarian action and international institutions. Through my Laidlaw research, I examine how ripeness theory and a Lederach-inspired cultivation approach can help explain the emergence and prospective transformative significance of TRIPP within the Armenia–Azerbaijan peace process. Alongside my academic work, my involvement with the Armenian and British Red Cross has strengthened my commitment to humanitarian values, ethical leadership and service to others. I am particularly interested in how rigorous research can move beyond the university environment and contribute to meaningful policy conversations and social impact. I am always delighted to connect with other scholars, exchange ideas and learn from people working across different disciplines, countries and communities.

I'm interested in learning everything about how the working class and common people of the world can work together to make their lives better. My main focus is developing skills to be an effective labor organizer and union leader.  I also have experience with policy research, legal advocacy, and statistics. 

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! 

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, I’m Isabella! I am a rising third year student at Georgetown University studying American Studies and Women’s and Gender Studies with a research focus on sexual violence, Christian nationalism, and gender policy. I am an educator and advocate for sexual violence prevention at both a cultural and legislative level.  This summer, I will be working with Dr. Nadia Brown and a fellow scholar to understand the occurrence and effects of violence against local-level women politicians. I am particularly interested in the influence of digital abuse involving AI and the effect that sexual harassment has on women’s political participation.  Please feel free to reach out!

Hi! My name is Daohui and I am a first-year Mathematics and Physics student at Durham University (2026). I look forward to being part of the 2026 cohort with my project about prevention and mitigation strategies of future global outbreaks by simulating and analysing the effects of COVID-19! I am particularly interested in applied mathematics and I believe that as the world becomes more and more interconnected, simulatory data will become increasingly important and impactful on global health. After the recent pandemic, there is undoubtedly still work to do in field of epidemiology, which is what I hope to contribute to.

I'm entering my second year at HKU this fall. It wasn't until now that I have somewhat solidified my interests to be at the intersection of Sustainability, Conservation, and Urban Planning of Asian Cities. Before joining uni, I took over three gap years working around the world and reflecting on my many identities. My work has spanned across Edtech, Heritage Conservation, Food Security, Nature Conservation, Policy Analysis, and Social Impact Sectors across the Global South. Beyond my work and research, I love to listen to music produced during from the 60s to 80s in anywhere around the world. I also love doing crafts as it notoriously saves me from supposed doomscrolling on Instagram. Also, I am secretly considering to debut as a private chef someday... who knows!?

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.

I am an undergraduate Laidlaw scholar from the University of St Andrews in Scotland currently conducting my research project. My research investigates the motivational drivers behind China's Environmentalism. 

Hi everyone! My name is Anna and I'm part of the 2026 Laidlaw Scholars cohort at Trinity College Dublin, where I study Mathematics with a minor in Statistics. For my research project, I'll be exploring a question that is becoming more important as AI develops: who is better at predicting the future, humans or algorithms? I'll be comparing forecasts from machine learning models with those from prediction markets, where collective human judgement is turned into live probabilities. After the 2024 US elections, prediction markets rapidly gained attention for correctly predicting the outcome before many traditional forecasts. At the same time, AI is making data-driven forecasting more powerful than ever. Through quantitative analysis, I'm curious to see whether the best predictions come from human insight, algorithmic pattern recognition, or perhaps a combination of both. More broadly, I am interested in using mathematics to better understand and solve real-world problems like this one. I'm especially drawn to the way it combines logic with creativity, allowing us to approach challenges from different angles and develop efficient and innovative solutions. Outside of academics, I'm also a huge music lover, from hip hop and rock to hard techno. For me, a good time almost always involves music, dancing, or both :) Feel free to reach out if you want to discuss research, share music recommendations, or simply chat!

Hi! I'm Kritvi, currently a rising sophomore at Barnard College of Columbia University intending to major in Economics and Mathematics. Having experienced educational and economic systems in India, the UK, and the United States, I've become fascinated by the factors that drive economic development. My interests lie in development economics, particularly how technology can address inequality and support sustainable growth in developing countries. I enjoy exploring questions at the intersection of economics, data, and social impact.

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.
