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.

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.

Welcome to my profile! I consider myself a service-oriented person. While I am not naturally extroverted, I am deeply driven by ethics, empathy, and the desire to improve people’s quality of life. I am currently majoring in Economics, but I am equally passionate about political science, history, and public policy. My interests lie in economic development, humanitarian action, and social entrepreneurship. Although I would not describe myself as an expert, but rather as a perpetual learner, I have been involved in volunteer initiatives in both the UAE and Senegal focused on poverty reduction, youth development, and food security.  To me, leadership is not defined by scale or recognition, but by consistent acts of service and responsibility toward others. Even the smallest initiatives can create meaningful impact, and that belief continues to motivate me to keep learning and building.

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.
