I am currently a researcher at the Research Institute on Computer Science (ICC, UBA/CONICET) in Buenos Aires and was appointed Assistant Researcher at CONICET in 2022. I received my Ph.D. in Engineering from the University of Buenos Aires in 2021, where I focused on developing modeling and simulation (M&S) methodologies for the design of hybrid controllers in cyber-physical systems (CPS), with application in autonomous and networked vehicles.
My postodoctoral research extends my previous work, focusing on the development of hybrid simulation tools for controlling autonomous vehicles and, more recently, for coordinating teams of multiple vehicles in complex or large-scale tasks. I have applied these methodologies in the design and validation of hybrid controllers of single autonomous vehicles, as well as distributed, collaborative controllers for networked multi-robot systems. Moreover, I have also been exploring novel design methodologies that integrate simulation models into the execution stage of control systems. This includes: (a) symbiotic simulation, where faster-than-real-time simulations help evaluate possible actions taking into account the future evolution of the system, and (b) model continuity, where the same models developed during the design stage are used to conduct real-time embedded simulation of the control model for robotics and IoT applications. Additionally, I have been exploring the integration of simulation with interactive and realistic visualizations, particularly in the context of Mixed Reality (MR) and Digital Twins (DT).
In parallel, I have actively taught undergraduate and graduate-level courses since 2014 at the School of Engineering (UBA), including Modern Automatic Control, Control Automation Laboratory , Industrial Automation , and Stochastic Processes.

abstract = {The design of distributed control strategies for multi-robot systems (MRS) relies heavily on simulations
to validate algorithms prior to real-world deployment. However, simulating such systems poses significant
challenges due to their dynamic network topologies and scalability requirements, where full inter-robot
communication becomes computationally prohibitive. In this paper, we extend the applications of the
Emergent Behavior DEVS (EB-DEVS) formalism by developing an agent-based model (ABM) to address
key distributed control challenges in networked MRS. The proposed approach supports both direct and
indirect interactions between agents (robots) via event messages and through macroscopic-microscopic states
sharing, respectively. We validate the model using a challenging cooperative target-capturing scenario that
demands dynamic multi-hop communication and robust coordination among agents. This complex use case
highlights the strengths of EB-DEVS in managing asynchronous events while minimizing communication
overhead. The results demonstrate the formalism’s effectiveness in supporting decentralized control and
simulation scalability within a hierarchical micro-macro modeling framework.},

We present a library of DEVS atomic models designed for simulation-environment interaction, enabling embedded software development through sensor data acquisition and actuator control. To demonstrate the practical utility of the embedded PowerDEVS framework, we evaluate its performance in real-world discrete-event control applications, including a line-follower robot and an electric kettle temperature regulator. These case studies highlight the approach’s versatility and seamless integration in IoT and robotic systems.},

abstract = {Designing hybrid controllers for cyber-physical systems (CPSs) where computational and physical components influence each other is a challenging task, as it requires considering the performance of very different types of dynamics simultaneously. Meanwhile, controlling each of these dynamics separately can lead to unacceptable results. Common approaches to controller design rely on the use of analytical methods. Although this approach can provide formal guarantees of stability and performance, the analytical design of hybrid controllers can become quite cumbersome. Alternatively, modeling and simulation (M&S)-based design techniques have proven successful for hybrid controllers, providing robust results based on Monte Carlo techniques. This requires simulation models and platforms capable of seamlessly composing the underlying hybrid domains. Unmanned Aerial Vehicles (UAVs) are CPSs with sensitive physical–computational couplings. We address the development of a hybrid model and simulation platform for a data collection application involving UAVs with onboard data processing. The quality of control (QoC) of the physical dynamics must be ensured together with the quality of service (QoS) of the onboard software competing for scarce processing resources. In this scenario, it is imperative to find safe trade-offs between flight stability and processing throughput that can adapt to uncertain environments. The goal is to design a hybrid supervisory controller that dynamically adapts the use of resources to balance the performance of both aspects in a CPS, while ensuring system-level QoS. We present the end-to-end M&S-based design methodology, which can be regarded as a design template for a broader class of CPSs.},

Then, we describe the QSS algorithms, their properties, their extensions, and the main practical software tools implementing them. We also present a selection of simulation examples illustrating the main features and advantages through comparisons with state-of-the-art continuous-time simulation solvers.},
