Tweedy, Jennifer - Imperial College London - Department of Bioengineering

个人简介

Jennifer Tweedy obtained a degree and PhD in Applied Mathematics from the University of Cambridge. Her PhD studies were in understanding pattern formation in the context of dynamical systems. She did postdoctoral work in blood flow and urology, before joining the Department of Bioengineering at Imperial in 2006. Her current research involves mathematical modelling of problems arising in medicine, medical practice and biology, especially problems involving fluid dynamics. She is also Associate Editor of the journal Trends in Applied and Computational Mathematics. Her research publications can be found at the tab above, or on Google Scholar. For more details on her research, please see her research pages. Note that many of her publications are under her maiden name, Jennifer Siggers.
