She leads an effort supported by NASA and NSF to determine the magnetic topology of heliospheric structures using in situ electron and magnetic field data from a number of spacecraft. She is best known for developing the concept of antiparallel merging, a process of coupling between the solar wind and the magnetosphere, for revealing the extent to which the solar wind consists of transient as opposed to steady-state structures, and for the central role coronal mass ejections play in governing the magnetic flux in the heliosphere.<\/span><\/p>\n<p><strong><\/strong><span><br \/>\n<\/span><\/p>\n","protected":false},"author":9387,"template":"","_links":{"self":[{"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/profile\/247"}],"collection":[{"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/profile"}],"about":[{"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/types\/profile"}],"author":[{"embeddable":true,"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/users\/9387"}],"version-history":[{"count":2,"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/profile\/247\/revisions"}],"predecessor-version":[{"id":1704,"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/profile\/247\/revisions\/1704"}],"wp:attachment":[{"href":"https:\/\/www.bu.edu\/csp\/wp-json\/wp\/v2\/media?parent=247"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
