Bacterial Community Development and Regulated Cell Death The Mashruwala Laboratory The Mashruwala Laboratory at the Stowers Institute for Medical Research invites applications for a Postdoctoral Research Associate . The laboratory studies bacterial communities through a developmental biology lens, asking how molecular events within genetically identical bacterial cells generate organized behaviors and spatial patterns across a collective. We are particularly interested in regulated cell death, collective cell-fate decisions and cell-cell communication as routes to discovering general principles of bacterial community development. The successful candidate will develop an original research direction within this framework , with substantial intellectual freedom. Approach, research, mentoring and professional development environment We combine bacterial genetics, molecular biology, advanced microscopy, quantitative image analysis, computational approaches, phenotypic analysis, and small-scale laboratory automation. Projects can expand into new methods or model systems when the biological question demands it. At Stowers, postdocs work in a highly collaborative environment with direct access to Ph.D.-level scientific partners in Technology Centers spanning advanced microscopy, genomics, proteomics, computational biology, and related areas. The Mashruwala Laboratory receives recurring intramural support from the Stowers Institute, providing flexibility to pursue unexpected findings and ambitious long-term questions. Our research is also supported by the Edward Mallinckrodt, Jr. Foundation. Mentoring is tailored to each researcher's background and goals. This ranges across experimental strategy and quantitative reasoning to writing to presentations to fellowship and grant applications to project management, and for researchers pursuing academic careers, preparation for the faculty job market. Stowers postdocs also have access to PostdocEDGE, a structured professional-development program covering grant writing, leadership, laboratory management, faculty-job preparation, and the transition to independent PI/Group Leader positions. Who should apply We welcome applicants from diverse scientific backgrounds who are excited by fundamental biological questions and by research that crosses traditional disciplinary boundaries. Prior experience with Vibrio cholerae is not required; we particularly welcome applicants who bring complementary expertise or perspectives.

• A Ph.D. in microbiology, molecular biology, genetics, biochemistry, cell biology, biophysics, computational biology, or a related field.
