Research at Mass General
Our multidisciplinary research program involves a combination of approaches including synthetic chemistry, neuroscience, and human genetics. Using this chemical-genomic approach, members of our research group invent new methods for finding small-molecule probes that target key components of the neurocircuitry, and then use these probes to selectively perturb neuronal network function at the molecular, cellular and circuit level. As a result of our work, we hope to develop novel, targeted therapeutics for treating neuropsychiatric disorders, including bipolar disorder, depression, schizophrenia, fragile X syndrome, and neurodegenerative disorders, including Alzheimer’s disease and Parkinson’s disease. We conduct this research program in close collaboration with other members of the Center for Human Genetic Research (CHGR) at MGH and the Stanley Center for Psychiatric Research. We are also affiliated with the Harvard Stem Cell Institute (HSCI).
Our studies entail three general types of experimental approaches:
Cellular and biochemical assays for screening small molecules, RNAi, and cDNA libraries are developed in order to enable discovery of agents targeting disease-relevant mechanisms and pathways identified by human genetics. Identification of targets and functional characterization of new molecular probes is performed using proteomic methods.
Neural stem cells, including induced pluripotent stem (iPS) cells from reprogrammed somatic cells, are being developed for characterizing the function of disease genes and pathways. These cell lines will eventually provide genetically accurate models for high-throughput chemical screening.
Small-molecule probes employing new mechanism of action are tested in animal behavioral models relevant to mood and memory disorders through collaborations with a variety of investigators interested in the development of novel therapeutics.

The role of chromatin-modifying enzymes in regulating transcriptional programs important to memory and mood are being investigated. Efforts to develop CNS penetrant, isoform selective inhibitors of class I/class II histone deacetylases (HDACs) and histone demethylases implicated in neuroplasticity and testing of these probes in vivo using behavioral models are underway.
The role of GSK-3/ β-catenin in regulating pathways important to neuropsychiatric disease is being investigated. Inhibitors of GSK-3 are being tested in animal models of behavior and efforts to develop CNS penetrant, allosteric, ATP non-competitive inhibitors of GSK-3β through medicinal chemistry are underway. A collection of small-molecule modulators of GSK-3/β-catenin signaling have been identified through a panel of cell-based, high-throughput screens and the relevant targets are being identified using RNAi and proteomics.
Genetically accurate neural stem cell models of mental illness are being developed in collaboration with the Harvard Stem Cell Institute and our genetics collaborators in Dr. Pamela Sklar’s laboratory at MGH. Patient-derived somatic cells with specific genomic abnormalities and haplotypes are being reprogrammed into induced pluripotent stem (iPS) cells to enable discovery of disease-associated phenotypes as the basis for small molecule and RNAi screens as well as functional studies of these disease mechanisms.
Small-molecule modulators of aberrant cell-cycle activity and DNA damage associated with neurodegeneration implicated in Alzheimer’s disease and LRRK2-mediated neurodegeneration implicated in Parkinson’s disease are being developed using cell-based and biochemical approaches.
The Haggarty Laboratory seeks highly motivated individuals to work in the area of chemical genomics of neuropsychiatric and neurological disorders. This is a unique opportunity for working in a fast-paced, and highly collaborative, translational research group working at the interface of chemistry, biology, and therapeutic development.
MD and/or PhD in neurobiology, molecular biology, chemistry, or related field required. Must posses familiarity with mammalian cell culture, fluorescence microscopy, and molecular biology. Must posses excellent computer skills and ability to perform basic quantitative analysis of large data sets. Knowledge of programs such as Spotfire, PipelinePilot and GeneData would be preferred. More advanced statistics or programming skills a plus. Excellent critical thinking skills and attention to detail needed. Must be able to use sound judgment to effectively solve problems, work independently, and handle a variety of tasks. Requires effective oral and written communication skills along with meticulous laboratory technique and recording skills. Must be able to use discretion to organize workflow and to change methodologies to optimize work results and communicate effectively with all levels of staff to ensure that work supports team goals.
