The evolutionarily conserved Wnt signal transduction pathway directs cell proliferation and differentiation during animal development and tissue homeostasis. Despite the fact that deregulation of Wnt signaling underlies numerous developmental disorders and cancers, including nearly all colorectal cancers, many of these mechanisms remain poorly understood. The long-term goal of research in the Ahmed Lab is to elucidate the mechanisms that activate Wnt signaling during animal development using a Drosophila model and to use this knowledge to identify control points in the pathway susceptible to therapeutic targeting in Wnt-driven diseases.

My research aims to understand how molecules within cells impart geometric information ultimately leading to cell shape determination. Research in my lab seeks to identify molecules within the cell that control cellular patterning. We are particularly interested in the role of regulators of the cytoskeleton and membrane trafficking and have pioneered the use of the moss Physcomitrella patens. Using the unusually rapid transgenic capabilities of moss, we are pursuing novel approaches to dissect the molecular mechanisms underlying plant cell shape.

Chromosome segregation errors in human oocytes are the leading cause of miscarriages and birth defects and their frequency increases dramatically as women age. Work in my laboratory is focused on defining the pathway of events necessary for chromosomes to "do the right thing"" during meiosis and understanding the molecular events that cause reduced fidelity of meiotic chromosome segregation as oocytes age.

My long-term research focus is to understand how bacterial toxins interact with the immune system to trigger pathogenesis or host protection. At Dartmouth, I will expand my research to investigate opportunistic bacterial pathogens that produce toxins and cause mucosal infections, such as those that occur in the lungs of Cystic Fibrosis patients. I will also be using synthetic immunology to develop novel therapeutics to combat opportunistic mucosal pathogens.

Our research focus is the cerebral cortex, an area of the brain that serves as the biological substrate for the higher cognitive functions that define us as individuals. We wish to identify the mechanisms by which individual cortical neurons process and transmit information within the cortical circuit. To accomplish this we employ electrical and optical recording techniques that measure neuronal activity in neocortical neurons under a variety of experimental conditions.

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.

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.
