Eugene Bell Career Development Professor in Tissue Engineering
Assistant Professor of Biological Engineering
“Our research combines protein engineering, structural biology, and bioinformatics to understand and manipulate immune-cell recognition and signaling. We are working to better understand the natural immune response, create novel immune tools and treatments, and develop methods to better study and engineer diverse repertoires of molecules.”
Michael Birnbaum is an assistant professor of biological engineering at MIT. He received his bachelor's degree in chemical and physical biology from Harvard University and his PhD from Stanford University in 2014. There, he worked under K. Christopher Garcia, and studied the molecular mechanisms of T cell receptor recognition, cross-reactivity, and activation. After postdoctoral work in Carla Shatz’s group at Stanford supported by a Helen Hay Whitney Postdoctoral Fellowship, Professor Birnbaum joined MIT and the Koch Institute in 2016. He is the Eugene Bell Career Development Professor in Tissue Engineering.
The immune system leverages immense molecular diversity in the T, B, and NK cell receptor repertoires to distinguish between normal cells and cells altered by infection or cancer. This molecular diversity often makes understanding exactly what is recognized during the course of an immune response extremely challenging. As a result, efforts to study antigen recognition have often been limited to working with model antigens.
The Birnbaum group focuses on understanding and manipulating immune responses in the context of cancer and infection. They use a variety of strategies and techniques including protein biochemistry, protein engineering, sequencing, and bioinformatics to 1) identify immune cells of interest, 2) determine the sequences of their antigen receptors, 3) directly determine what the immune response is ‘seeing’ in response to cancer or infection, and 4) answer questions about how the immune system composition and dynamics affect the success or failure of an immune response. This type of systematic, unbiased examination of the antigen recognition repertoire of any given T or NK cell receptor has, until recently, been extremely difficult. With this information, Professor Birnbaum and his team will be able to rationally engineer new methods to more specifically mount a potent immune response.
