SOM News: Leadership team selected for new Ph.D. Program in Biomedical Sciences.

Welcoming new faculty: Please join us in welcoming Bahareh Ajami, Ph.D., as an assistant professor, to the Department of Molecular Microbiology and Immunology and the Department of Behavioral Neuroscience. Dr. Ajami’s research is focused on advancing our understanding of the function and biology of the brain’s intrinsic immune cells: microglia. 

Dr. Ajami's previous work has established the fate and origin of microglia in the brain during health and disease. In her most recent work, by adopting a novel single-cell proteomics approach, CyTOF (mass cytometry), Dr. Ajami has demonstrated that microglia are a network of cells comprised of several subpopulations with distinct immune responses in different neurological disorders. This work has resulted in the discovery of a new therapeutic target for Multiple Sclerosis and ALS disease and has recently been licensed by a biotech company for further development. 

Drawing on her recent discovery of different microglia subsets combined with proteogenomics approaches and computational methods, Dr. Ajami’s research program will focus on understanding of microglia subset functional specialization and the mechanisms that control the functional identity of different subsets both in mice and humans. Her lab will examine how these regulations are changed in different neurodegenerative diseases such as ALD and AD, revealing their endowed capacity to induce distinct types of neurodegenerative diseases and designing novel strategies to target them for therapies.

Open position for an assistant professor: The Department of Molecular Microbiology and Immunology, in collaboration with the Department of Behavioral Neuroscience, invites applications at the assistant professor level to work on the basic or translational aspects of neuroimmunology. See Research Opportunities for details.

A new recruitment has been opened for the Dean’s Research Scholar Program.  Applications are due by November 25, 2018. Find details on the program and application requirements.

Congratulations to Ruth Napier, Ph.D., for getting awarded a Medical Research Foundation Grant for her project Investigation of NOD2 as a T cell intrinsic regulator of rheumatoid arthritis.
