Shelley is an applied mathematician who works on the modeling and simulation of complex systems arising in physics and biology. This has included, of late, modeling the dynamics of complex and active fluids, and examining transport and self-organization processes in cellular biophysics. He is co-founder and co-director of the Courant Institute\u0027s Applied Mathematics Lab at New York University, and is the Director of the Center for Computational Biology at the Flatiron Institute. He is a Fellow of the American Physical Society, the Society for Industrial and Applied Mathematics, and the American Academy of Arts and Sciences, and is a member of the National Academy of Sciences.\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EFlows in the fluidic interior of living cells can serve function, and by their structure shed light on how forces are exerted within the cell.
