Harvard Researcher Wins Top Prize for Breakthrough Tuberculosis Research

A Harvard University PhD student has been awarded a prestigious prize for her groundbreaking work on drug-resistant tuberculosis (TB). Abigail Frey, a student in the Biological Sciences in Public Health program, won the 2026 Three-Minute Thesis (3MT) competition for her research focused on identifying genetic mutations that contribute to antibiotic resistance in Mycobacterium tuberculosis.

The Challenge of Drug-Resistant TB

Tuberculosis remains a significant global health threat, responsible for 1.23 million deaths in 2024, according to the World Health Organization . A growing concern is the rise of drug-resistant TB, where standard treatments are ineffective. Approximately 1 in 25 cases of TB are drug-resistant .

Frey’s Research: Unlocking the Genetic Code of Resistance

Frey’s research centers on identifying the specific genetic mutations within the TB bacterium that allow it to evade the effects of antibiotics. Currently, not all of these mutations are known, hindering accurate diagnosis and effective treatment. Her work combines population genomics and bacterial genetics to map these “antibiotic escape mechanisms” .

“The best way to perform this diagnosis is by screening the DNA of the bacteria for drug resistance mutations,” Frey explained . Identifying these mutations will pave the way for faster, more accurate diagnostic tools, enabling clinicians to prescribe the most effective treatment regimens.

The Fortune Lab and the Fight Against TB

Frey conducts her research in the Fortune Lab at the Harvard T.H. Chan School of Public Health, which is dedicated to understanding tuberculosis and its interaction with the host immune system . The lab’s broader goal is to eradicate TB by developing latest therapeutics, vaccines, and public health strategies . The Fortune Lab emphasizes a collaborative, multidisciplinary approach, integrating bacteriology, immunology, genetics, genomics, computation, clinical medicine, and chemistry .

The Three-Minute Thesis Competition

The Three-Minute Thesis (3MT) competition, originally developed by The University of Queensland, challenges PhD students to present their research in a concise and accessible format – just three minutes long . The competition aims to cultivate students’ communication skills and their ability to explain complex research to a non-specialist audience .

Looking Ahead

Abigail Frey’s research represents a significant step forward in the fight against drug-resistant tuberculosis. By unraveling the genetic basis of antibiotic resistance, her work promises to improve diagnosis, treatment, and save lives. The ongoing efforts of researchers at the Fortune Lab and beyond are crucial in addressing this persistent global health challenge.
