Hello!
My name is Tony Savostianov.
Recently I've defended my PhD in Mathematics in Natural Science at Gran Sasso Science Institute in L'Aquila, Italy.
My current work is focuses on the numerical methods for Network Sciences. My previous work included:
- coupled (nonlinear) oscillators for modelling solar activity
- detection of 3D structure in chromatine via CV methods
- quasi stationary points in spatially-heterogeneous models of biocommuinites
