Hello! My name is Lilly Heffernan and I'm a 2026 Laidlaw Scholar from Trinity College Dublin. I'm interested in the way in which human effects on animal behaviour influence their disease spread. 75% of emerging diseases are coming from animals, and I believe that we can manage this in an effective and humane way.  I'm exploring this topic by investigating how artificial light changes how bats use space, and stresses their immune systems. I suspect that artificial light negatively impacts bat immunity, making them more likely to spread disease. This may be a reason we are seeing more human pathogens which originate from bats, such as SARS-CoV-2, and Ebola virus.  I strongly believe that we can curb the spread of these diseases by understanding how our behaviour is affecting our ecosystem. We cannot have healthy humans without healthy animals. This approach targets new pathogens before they spread to humans. If we focus on this angle, we can prevent the inefficient and cruel practice of culling sick animals for our own benefit. 

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. Feel free to reach out if you want to discuss research or simply chat!

I am a rising sophomore at Harvard college pursuing a double concentration in Computer Science and English. For my research summer I worked at Harvard Kennedy School's Fandom and Social Connection Initiative, investigating how shared sports fandom can be used to mitigate the effects of social isolation. I am interested in the intersection of technology and social connection, and how we can use digital tools to create a more connected society.

My name is Rosalind and I'm a first year student in psychology at the University of Cambridge. I am particularly interested in the interection between physical and mental health and how psychological and neurological processes can impact somatic functions. Another major interest of mine is the maintenance of mental health recovery, and how post-acute care in communities and systems can support the longevity of recovery and prevent relapse.

Hello! My name is Anjelica and I'm a student at Columbia University in New York. My current research aims to look into how language shapes the discourse on femicide in the media. In my free time, I make podcast videos with people who I find inspiring, I write (and hunt for banger book quotes on Pinterest), I'm currently planning an initiative in my foundation, and I love improv comedy. A quote that I really love as of now is: "When God had made The Man, he made him out of stuff that sung all the time and glittered all over. Some angels got jealous and chopped him into millions of pieces, but still he glittered and hummed. So they beat him down to nothing but sparks but each little spark had a shine and a song. So they covered each one over with mud. And the lonesomeness in the sparks make them hunt for one another." Zora Neale Hurston, Their Eyes Were Watching God And yes, I love existential questions.

I am the Programme Manager for the Laidlaw Scholars Leadership & Research Programme at Trinity College Dublin. Before joining the Careers and Development Service at Trinity College Dublin, I have been looking after a portfolio of open enrolment short executive education courses at Trinity and have over 10 years of experience in admissions, event coordination and higher education management across Ireland, United Kingdom and Ukraine.

Hello, my name is Hannah Treagus, I'm a current 3rd year psychology student at The University of St Andrews. My research project titled "Exploring the Impact of Wellbeing Intervention Strategies on Master’s Students: Valuing the Student Voice" is focused on exploring and advocating for the underrepresented voice of postgraduate taught (PGT) students. I'll be working with a group of postgraduate students to create a student-led intervention that can hopefully be utilised globally as a wellbeing tool. I have a significant interest in Educational Psychology but would love to connect with scholars of any discipline. I also love travel, photography, baking and horse riding in my free time and am always up for a chat!

Hello! I'm Sonia, a student of Political Science and Economics at Trinity College Dublin. I'm also a 2026 Laidlaw Scholar. In research and in everyday life, my main interest is how the traumas of the past affect the wellbeing of people in the present. War, structural discrimination and communal violence rarely conclude at appointed historical end dates, but persist in the daily realities of communities for decades. The impacts are often invisible and difficult to quantify, such as chronic stress, sectarianism and complex national identification. My Summer 1 research examines the modern-day impacts of Ireland's revolutionary past. In the 1920s, over 275 Irish country houses were burned in conflicts over land, religion, class and politics. I will interview members of the tight-knit rural communities where the burnings occurred. My objective is to understand how that legacy of violence impacts people's sense of belonging. I hope to connect with fellow Scholars and alumni. Especially if you have an interest in conflict, peacebuilding or memory politics, get in touch!

Hi everyone! I am a sophomore at Tufts University in Boston, studying biology and environmental science. I am originally from Cape Town, South Africa, and attended high school in Louisiana. This summer, I am working in Tanzania on a coral restoration project, conducting my own experiment to identify which coral species will be most resilient during this year's El Niño and rising sea temperatures. I will also be exploring how to make the coral gardening process more cost-effective and accessible to coastal East African fishing communities. 

I'm an incoming 3rd year Law and German student in Trinity College Dublin.   My research centres on how the criminal justice systems responds to abused women who kill their abusive partners.  The defences to a charge of killing are usually provocation, self-defence, and diminished responsibility/insanity.  However, feminist legal theorists argue that these defences arise out of a typical male rather than female experience.  Victims of domestic abuse who kill typically lack an obvious imminent threat of violence, which is required to use the legal defences, and instead are responding to a cycle of violent behaviour. I want to understand how these women are treated in criminal justice systems, and how we can improve the law in this area. I am passionate about improving equality and fair treatment in the legal system, as well as gender studies and criminology.  I would love to get in touch if you are interested in any of these areas!

Hi! My name is Stephanie, and I am a medical student from Trinity College Dublin. I am drawn to how medicine helps us understand our brains, people, society, and systems to improve health and well-being. My research project examines the intersection of climate change and brain health from a policy perspective. Climate change is often framed as an environmental emergency. However, its consequences such as extreme heat, disaster-related trauma, and air pollution have an indispensable toll on brain and general health. Yet, global frameworks and mitigation strategies continue to treat health and neurological wellbeing as an afterthought. My project will uncover how current policy guidelines and interventions lack investment in population wellbeing and health. I aim to work with experts in the field and together build a framework to help countries tailor their climate-health responses with an emphasis on brain and general health. With this interdisciplinary and international approach, I hope to expose and close the gap between policy and wellbeing, translating scientific discovery to real-life health and comfort.  Outside of classes and placements, you can find me outdoors pretending to study in the sun or travelling. I also enjoy Olympic target shooting and hiking.  Very grateful and excited for the Laidlaw journey ahead, feel free to reach out and connect! 

Hello! I’m a psychology researcher and the founder of HaHaHelps, a nonprofit organisation developing and delivering 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 programme 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.

Hey! My name is Leah Carroll, I am a current 3rd year student of English Studies at Trinity College Dublin and a member of the 2026 Laidlaw Leadership & Research Scholars cohort. After an unconventional path as an early school-leaver, I found my way to higher education through the Trinity Access Programme’s Foundation Course for Young Adults to pursue my lifelong passion for literature. While curious for all facets of the field, I have keen interest in women’s issues and feminist theory.   My research project, entitled ‘"Girls Who Say Nothing and Wear Black": Women of the Beat Generation’, aims to address an important critical gap by examining the continued marginalisation of women Beat poets despite their acknowledged literary and cultural influence. The study aims to contribute a more equitable understanding of the Beat generation as well as a broader appreciation of their influence outside the United States with particular reference to their importance to contemporary Irish women’s poetry.   Outside my studies and research, I love writing both prose and poetry, working on my own creative projects, going hiking with friends, and indulging in sports such as horse-riding and figure skating.  Please feel free to reach out and connect!

Hi, my name is Peter McNulty. I am an Undergraduate Leadership & Research Scholar at Trinity College Dublin. For my research project, I will be "Pricing the environmental impact of AI-related data centre energy consumption in Ireland" as I think that it is important to balance AI's economic benefits with the growing emissions and energy consumption burden that Ireland faces. This will involve a literature review of EU Carbon Policy, research into carbon market trends and computation of AI-specific consumption costs using EU ETS pricing frameworks. Outside of my studies, I play guitar, piano and sing in pubs! I also enjoy running long distances for charity.

Hi! My name is Hayden Chernow and I am from Boston, Massachusetts. I am a rising junior at Barnard College majoring in Urban Studies with a focus on the Middle East and Education.  My Laidlaw Scholars Research topic will examine how Jordan's growing refugee population impacts access to trauma-informed education.

Hello! I'm Crystal, a current third year medical student from Trinity College Dublin, and originally from Yangon, Myanmar. I think physicians are in a unique position where they are entrusted by patients, understand firsthand the shortcomings in patient care, and possess the biomedical knowledge and skills needed to drive meaningful change, placing them at the forefront of cutting-edge research that can directly benefit patient care. I would love to be a physician-scientist one day who can bridge scientific discovery with clinical practice.  My research explores the effects of smoking on innate immunity and Chronic Obstructive Pulmonary Disease (COPD). I am fortunate to be part of a great research lab that allows me to explore my own ideas, design my own experiments, and, most importantly, keep moving forward when things do not go as planned!  I also love cooking and baking -- I am always thinking of what I should have for my next meal! 

Dia dhuit! My name is Seán Radcliffe and I am an Economics and Mathematics student at Trinity College Dublin. Outside of my studies, I am a political campaigner, pro-Palestine activist, and the Housing Rights Officer of my student union. I love to sing, travel, and have a laugh! This summer, under the academic supervision of Trinity Fellow and Associate Professor Dr. Davide Romelli, I will be conducting research at Trinity College Dublin on the effects of economic conditions, shocks, and crises on cocaine-related harm and deaths in Ireland between 2004 and 2024; "Reading Between the White Lines: An Investigation into Cocaine-Related Harm in Ireland During Periods of Economic Change and Crisis, 2004-2024." Using statistical analysis and interviews with experts, policymakers, and activists, my project aims to challenge damaging assumptions around drug addiction and harm in Ireland, particularly narratives that simplistically link economic growth and employment with reduced harm. Grateful for this opportunity and excited for what lies ahead.
