Chemistry is truly the central science and underpins much of the efforts of scientists and engineers to improve life for humankind. TheMIT Department of Chemistryis taking a leading role in discovering new chemical synthesis, catalysis, creating sustainable energy, theoretical and experimental understanding of chemistry, improving the environment, detecting and curing disease, developing materials new properties, and nanoscience.
The Chemistry Education Office staff is responsible for administering the educational programs in the Department of Chemistry. Students can find answers to many questions about the undergraduate and graduate programs on the department website, and they are encouraged to stop by and see the staff in the office located in 6-205.
The student-run outreach programs in the Department of Chemistry aim to bring the excitement of chemical sciences to the community through lively demonstrations designed to illustrate a broad range of chemical principles. Graduate students visit science classes in high schools and middle schools in the Greater Boston area with a view to demystifying chemistry through hands-on experiments. ClubChem, an undergraduate chemistry organization, conducts Chemistry Magic Shows for elementary schools and youth programs in the Greater Boston area.

Maintaining the proper three-dimensional structure, concentration, activity, and localization of proteins is a critical and constant challenge for all organisms. Dysregulated protein homeostasis is inextricably linked to disease states. Accordingly, the most prominent diseases of modern times—including neurodegenerative diseases like Alzheimer’s disease, diabetes, loss-of-function diseases like cystic fibrosis, many types of cancer, and even viral infections—are either caused directly by a failure to maintain protein homeostasis or reliant on innate cellular protein folding mechanisms. Proteome repair achieved by targeting the cellular mechanisms that regulate protein folding could transform the therapeutic options for broad swaths of protein folding-related disease. Critically, methods to intervene in a single important protein folding pathway could be applied to multiple, diverse pathologies.
Before proteome repair can mature as a therapeutic strategy, we must learn much more about how proteins fold in the cell and about the specific cellular mechanisms we can exploit to rescue pathologic protein folding problems without globally disrupting cell health. Few selective chemical and chemical biologic tools currently exist to explore these issues in vivo. The Shoulders Laboratory is focused on integrating the tools of chemistry and biology to elucidate the complex pathways responsible for maintaining cellular protein homeostasis. Our lab employs a multi-disciplinary approach to (1) understand at the molecular level how the cell remodels itself to address challenges to protein homeostasis, (2) elucidate the pathophysiology of protein folding-related diseases with poorly defined etiologies, and (3) target the biological processes we uncover for the development of new small molecule probes, tools, and (ultimately) drugs.
We are particularly interested in developing and applying chemical biology tools and bioorthogonal chemistry to elucidate how cells dynamically adjust the molecular identities of proteins in response to dysregulated protein homeostasis. In this area, our initial focus is on cancer-related and stress-induced post-translational protein modifications—such as N- and O-glycosylation. We also work to understand the etiologies of and develop new therapeutic strategies for incurable orphan diseases that derive from missense mutations to extracellular matrix proteins, such as osteogenesis imperfecta. These disorders are powerful models for entire categories of protein folding-related diseases. As we discover and characterize pathways involved in cellular protein folding, we also develop new chemical entities that modulate those pathways for the treatment of protein folding-related diseases.
Members of the Shoulders lab gain expertise in organic chemistry, biochemistry, biophysics, and cell biology in an atmosphere that promotes creativity and bold ideas. We employ a wide range of experimental techniques including chemical synthesis, molecular biology, peptide and protein preparation and purification, tissue culture, spectroscopy and biophysical measurements (IR, UV-Vis, NMR, CD, AUC, DSC, DLS, ITC, MS), microscopy, and high-throughput assay development.
