Investigating microbial interactions in the female urogenital tract to improve women’s health, our lab explores how host-microbe and microbe-microbe dynamics influence vaginal health and pregnancy outcomes. With bacterial vaginosis affecting nearly 30% of women and linked to infections, infertility and adverse birth outcomes, we employ animal models, cell culture systems and clinical specimen analysis to uncover mechanisms driving these conditions. Our goal is to translate discoveries into targeted prevention and treatment strategies that enhance health for women and their babies.

Investigating the origins of genome instability in childhood cancers, our lab seeks to understand how DNA damage responses shape tumor development and therapeutic outcomes. Unlike adult malignancies driven by aging or environmental carcinogens, pediatric cancers arise through distinct mechanisms that remain poorly understood. Our long-term goal is to identify predictors of mutagenesis and uncover vulnerabilities within DNA damage response pathways, paving the way for innovative treatments that improve survival and quality of life for children with cancer.

Investigating cross-generational epigenetic regulation and its impact on health and disease, the Greer Lab explores how non-genetic information shapes complex physiological and pathological traits across generations. By studying molecular determinants of epigenetic memory, we aim to uncover how environmental changes influence health, development and longevity, and how disruptions in these mechanisms contribute to disease. Our research seeks to illuminate the processes behind epigenetic inheritance and identify strategies to improve outcomes for future generations.

Research profile

Exploring mechanisms and differences in artery development in the context of extracellular matrix gene mutations our lab studies how vascular elastic fibers form and how defects in this process lead to diseases such as aneurysms and hypertension. Using models with fibulin-4 mutations we investigate why large arteries show fragmented fibers while small arteries remain intact, aiming to uncover how these differences contribute to aneurysm development.

Research profile

Uncovering early-life viral and bacterial interactions, our laboratory investigates how microbial communities in the infant gut shape health and disease. Combining epidemiology, bioinformatics and molecular virology, we study the evolution of gut viruses, their interplay with bacteria and their role in conditions such as celiac disease. By advancing understanding of these complex dynamics, we aim to improve pediatric health and long-term outcomes.

Research profile

Investigating genetic impacts on cilia function to combat airway diseases, our laboratory examines how mutations disrupt the biology of airway and motile cilia, impairing mucociliary clearance and driving conditions such as primary ciliary dyskinesia, asthma and COPD. Using primary human and mouse cell cultures with advanced genetic manipulation, we study airway epithelial differentiation and ciliogenesis to uncover the roles of novel proteins and develop strategies to restore cilia function and protect respiratory health.

Research profile

Unraveling the mechanisms of glucose transport, our laboratory investigates how facilitative glucose transporters regulate normal and disordered glucose homeostasis. Focusing on structure–function relationships within GLUT proteins, we apply advanced chemical and biophysical techniques to define the architecture of GLUT1 and GLUT4. In parallel, we examine how HIV protease inhibitors alter GLUT function, aiming to uncover molecular pathways that contribute to insulin resistance in treated patients.

Research profile

Exploring molecular pathogenesis and sex differences in pyelonephritis, our lab investigates interactions between pathogenic Gram-negative bacteria and their hosts using urinary tract infections as a primary model. We aim to understand host-pathogen dynamics in the urinary tract, how uropathogenic bacteria modulate immune responses and the role of sex in UTI pathogenesis.

Research profile

Focus on understanding disease mechanisms and mitigating ongoing pandemic risks our lab characterizes novel viruses to uncover how they cause disease in humans. While viral discovery has expanded known sequences many questions about viral biology require isolation and propagation in the lab. With human populations vulnerable to emerging pathogens we aim to advance knowledge that informs preparedness for future pandemics.
