Research interests
I am passionate about developing new concepts and methods and applying the produced results to real-life problems. Currently, my main research interests are: Nonlinear Dynamical Systems Analysis and Control, Synthetic Biology, Systems Biology.
I am currently interested in the modelling, analysis, design, control, and implementation of cellular systems (in particular biomolecular feedback systems and gene regulatory networks); and in applications of systems and control engineering methods to the problem of robustly and optimally controlling natural or synthetic biology systems, e.g., robust control of gene regulation networks or optimal drug cocktails scheduling for chronic-like diseases treatments (e.g. cancer and HIV).

Ph.D. Thesis
The title of my Ph. D. thesis is Global analysis and synthesis of oscillations: a dissipativity approach.
Abstract:
The main theme of this research concerns the global (as opposed to local) analysis and synthesis of stable limit cycle oscillations in dynamical systems. The global analysis of oscillations in systems and networks of interconnected systems is a longstanding problem. Dynamical systems that exhibit robust nonlinear oscillations are called oscillators. Oscillators are ubiquitous in physical, biological, biochemical, and electromechanical systems. Detailed models of oscillators abound in the literature, most frequently in the form of a set of nonlinear differential equations whose solutions robustly converge to a limit cycle oscillation. Local stability analysis is possible by means of Floquet theory but global stability analysis is usually restricted to simple (second order) models. For these simple models, global analysis is performed by using specific low dimensional tools (phase plane methods, Poincaré-Bendixson theorem, etc.) which do not generalise easily to complex (high dimensional) models. As a consequence, global analysis of complex models is quite difficult since there currently exists no general analysis method. This lack of general analysis methods typically forces complex models of oscillators to be studied only through numerical simulation methods. Although numerical simulations of these models may give a first insight into their behaviour, a more in-depth understanding is generally impeded by the complexity of the models and the challenge of rigorous global stability analysis. Moreover, even in the case of simple models, the low dimensional methods used for their analysis do not generalise to the analysis of a network of interconnected oscillators. These considerations show the need for developing general methods that allow the global analysis of oscillators, either isolated or in interconnection. This thesis constitutes the first step towards the development of such a unified oscillators theory. In this aim, this thesis considers an extension of the dissipativity theory introduced by Willems. Nowadays, dissipativity is considered as one of the most general nonlinear (global) stability analysis method for equilibrium points in dynamical systems and networks of interconnected dynamical systems. In this thesis, we show that dissipativity theory can be extended to allow (global) stability analysis of limit cycles in many Lure-type models of oscillators and networks of oscillators. These Lure-type models of oscillators have been named passive oscillators. As the main contributions of this research, we show the implications of this extended dissipativity theory for
- the global stability analysis of isolated passive oscillators
- the global stability analysis of networks of passive oscillators
- the global stability analysis of synchronised oscillations in networks of identical passive oscillators
Furthermore, based on these results, we also propose a limit cycle oscillations synthesis method based on the design of a nonlinear parametric proportional-integral controller aimed at the generation of limit cycle oscillations with large basins of attraction in stabilisable nonlinear systems.

Master's Thesis
The translated title of my master thesis is Creation of an autonomous impulse response measurement system for rooms and transducers with different methods - "Réalisation d'une chaine de mesure autonome de la réponse impulsionnelle de salle selon différentes méthodes" (the manuscript is in french).
Abstract:
In this thesis, we compare four of the most used impulse response measurement techniques: Maximum Length Sequence (MLS), Inverse Repeated Sequence (IRS), Time Stretched Pulses, and Logarithmic Sinesweep. These methods are generally used for the measurement of the impulse response of acoustical systems such as transducers, rooms, and binaural impulse responses. The choice of one of these methods depending on the measurement conditions is critical. Therefore an extensive comparison has been realised. This comparison has been done through the implementation and realisation of a complete, fast, reliable, and cheap measurement system. In particular, these different methods have been compared with respect to best achievable signal-to-noise ratio, ease of use, harmonic distortion rejection/measurement, and robustness to measurement conditions (temperature change, impulsive and white noise, etc.). It is shown that in the presence of non white noise, the MLS and IRS techniques are more appropriate. On the contrary, in quiet environments the Logarithmic Sinesweep method is the most accurate: it allows for a direct improvement of the signal-to-noise ratio of up to 30 dB over the other methods, which can be critical for audio virtual reality systems such as auralization systems. Indeed, capturing binaural room impulse responses for high-quality auralization purposes requires a signal-to-noise ratio of more than 90 dB which is unattainable with other measurement techniques due to inherent nonlinearities in the measurement system (especially the loudspeaker), but fairly easy to reach with logarithmic sinesweeps due to the possibility of completely rejecting (and measuring) harmonic distortions. As a consequence, the sinesweep method opens the way for the development of high-quality auralization and sound spatialisation systems, which constitute the basis for advanced audio virtual reality systems.
