Welcome to my personal webpage

I have an Engineering degree - Major in Data Science (obtained from École des Pont ParisTech, France) and a MSc in Applied Mathematics and Informatics (obtained from NSU, Russia).

Currently, I’m enrolled in PhD at Inria Méditerranée supported by the French government, through the 3IA Côte d’Azur Investments. I’m pleased to present a short description of my PhD and other projects where I’ve participated during my studies.

PhD project in Deep Learning applied to Cardiology

I started my PhD, named Learning Cardiac 3D Electromechanical Dynamics with PDE-based Physiological Constraints for Data-Driven Personalized Predictions in Cardiology, in march 2020 under supervision of Maxime Sermesant (Inria, Epione) and Patrick Gallinari (Sorbonne University, LIP6, MLIA).

The scientific objective of this project is to combine the advantages of biophysics and deep learning methods, and to develop hybrid models exploiting the complementarity of the two approaches. The main idea is to introduce physiological priors in learning systems through biophysical modelling by learning spatiotemporal dynamics from simulations and by introducing physically motivated constraints relative to these dynamics.

The objective is to exploit optimally the large amounts of data available in this field together with well-known properties of biophysical cardiac dynamics. Besides, this would also enable to propose a datadriven correction of biophysical models error.

Previous projects

Passioned by computer vision and the applications of GANs and VAEs for image translation and synthesis I’ve also participated in the different (non deep learning) projects to get a deep understanding of basic image processing. More than that, I have a strong background in math and I’ve been doing research on global optimization methods for multi-dimensional functions for several years.

The list of my projects is below :

Population based epidemiological modelling (Research project in mathematics)

KASHTANOVA Victoriya, supervised by KABANIKHIN Sergey and KRIVOROTKO Olga
Russia, 2017
/ arxiv / code

Knowing that the models of the epidemic spread could be described by systems of nonlinear ODEs whose coefficients characterize the features of population and disease.I worked on the construction and investigation of numerical algorithms for determining these coefficients by the global minimization of the multidimensional target function.

  • Investigated methods : Genetic algorithms, Simulated annealing algorithm, Tensor Train method etc.
  • Implementation of tools for solving the direct and inverse problems for systems of ODEs.
  • Python, C++
