New Trends in the Applications of Differential Equations in Sciences

Angela Slavova obtained her Master's degree in Computer Science (1986) and her PhD in Mathematics (1994) from the University of Ruse, Bulgaria. In 2005, she became a Doctor of Science and, in 2007, a Full Professor at the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences. Since 2004, Prof. Slavova is Head of the Department of Mathematical Physics, Institute of Mathematics, Bulgarian Academy of Sciences, and, since 2011, Head of the Department of Differential Equations and Mathematical Physics at the same Institute. Her research work focuses on the field of differential equations; cellular nonlinear and nanoscale networks; nonlinear waves propagation; equations of mathematical physics; and applications of differential equations in sciences.
