My research focuses on the role of lung macrophages in the development and persistence of inflammation in the lung. A major focus of my laboratory is the investigation of potential mechanisms underlying regional heterogeneity of lung inflammation in patients with inflammatory lung diseases, with an emphasis on the investigation of differences in alveolar macrophage function in patients with cystic fibrosis and asthma. Our work involves primary human immune cells isolated from patients with cystic fibrosis and asthma, as well as healthy volunteers and chronic smokers. Currently, my laboratory is particularly interested in how the lung environment impacts resident and recruited macrophage phenotype and function and how these changes in the immune cell may contribute to the non-resolving inflammation seen in patients with CF. In addition to our work in inflammatory lung diseases such as CF, we are investigating the relationship between impaired lipid homeostasis in lung macrophages and viral immunity in individuals who use electronic cigarettes.

My long-term research focus is to understand how bacterial effectors that are secreted into leukocytes trigger pathogenesis or host protection. We study a professional pathogen (Yersinia) that causes disease in healthy humans and two opportunistic pathogens (Burkholderia, Pseudomonas) that cause airway infections in people with cystic fibrosis. The laboratory uses a multidisciplinary approach including genetics, structural biology, cell biology and immunology. Our goals are to answer important questions in the field and inform new strategies for preventing or treating bacterial infections caused by these pathogens.

My laboratory's research examines the interaction between bacterial and viral pathogens in the respiratory tract, particularly in the setting of chronic lung diseases, like Cystic Fibrosis (CF). Current studies in the lab are focused on elucidating molecular mechanisms that govern the innate immune induction of biofilm growth in the lung. Translating the laboratory's bench studies to the bedside, our team collaborates with physicians in Otolaryngology and Pulmonary Medicine to examine viral-bacterial interactions in the upper and lower respiratory tracts of patients with chronic lung disease. We use a combination of live-cell imaging, microbiological, cell biological and cutting-edge genomics approaches with the long-term goal of identifying new therapeutic targets to disrupt and/or prevent the chronic Pseudomonas aeruginosa biofilm infections that are so devastating to people with CF.

The Lee Lab studies the dynamics of antibody repertoires in infectious disease, autoimmune disease, and cancer using high-throughput sequencing of B cell transcripts and high-resolution mass spectrometry. The repertoire of antibody molecules circulating in blood or coating mucosal surfaces is the basis for protective immunity, and we employ machine learning frameworks, big data analytics tools, proteomic analytical methods, and data modeling to gain clinically relevant insights regarding protective mechanisms at unprecedented details. Leveraging this knowledge, we aim to design next-generation therapeutics and vaccines precisely tailored to maximize effectiveness in the context of particular diseases and/or patients (i.e. personalized/precision medicine).

My lab is interested in how cells grow and divide to form complex structures, such as the transformation from the zygote to an adult human or from a transformed cell into a tumor mass. To study these processes, we develop technologies to trace pattern of cell divisions which recovers the lineage of each cell. This information can be combined with other measures of cell state such as single-cell transcriptomic data to develop a rich picture of how choices are made in development and how this process is dysregulated in diseases such as cancer.

Bacteria often live in groups, called biofilms, where they cooperate and compete using a broad spectrum of interactive behaviors. These interactions are central to how bacteria evolve, and how they cause disease. We use molecular genetics, confocal microscopy, computational simulations, and evolutionary analysis to understand the mechanisms and biofilm-scale consequences of bacterial cell-cell interaction.

Our research focuses on understanding the function and regulation of virus-specific resident memory T cells (TRM). Using mouse and human tissue explant models, we seek to develop a foundational understanding of TRM biology in distinct tissues to be able to contextualize the role of TRM in pathologic and protective settings. Our current focuses are on the functions of anti-viral TRM in the brain, repurposing virus-specific TRM as a brain tumor immunotherapy, and investigating the role of TRM within tumors during oncolytic viral therapy.

The bacteria resident in the human gastrointestinal tract (the gut microbiota) potently influence diverse aspects of human health, including immunity. However, the forces that govern the composition of the gut microbiota are poorly understood. Our work focuses on a mechanistic, ecological, and evolutionary understanding of how interbacterial interactions between members of the dominant Gram-negative bacteria in the gut, the Bacteroidales, modulate the composition of the microbiota. The Bacteroidales utilize a contact-dependent toxin-delivery system known as the type VI secretion system (T6SS) to kill neighboring cells. We study the impact of this pathway on the microbiota and how bacteria adapt to defend against T6SS-mediated antagonism, using a combination of bacterial genetics, biochemistry, metagenomics, and germ-free mouse models. We are also interested in understanding why Bacteroidales abundance is depleted in individuals with cystic fibrosis, with the goal of improving health through restoration of these bacteria.
