Interplay Between Learning and Control: Robustness of Learning Algorithms and Data-Driven Controller Design

Leilei Cui, University of New Mexico

Wednesday, April 1, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

Learning and control are deeply intertwined disciplines. On one hand, control theory provides a rigorous mathematical framework for understanding, analyzing, and certifying learning algorithms. On the other hand, learning enables data-driven, model-free controller design for dynamical systems.

At the core of most learning methods lie gradient-based optimization algorithms, whose performance in practice is inevitably affected by disturbances such as data noise and computational inaccuracies. These perturbations raise a fundamental question: Can optimization algorithms maintain convergence to near-optimal solutions in the presence of disturbances? To address this question, we leverage tools from control theory—particularly input-to-state stability (ISS)—to rigorously analyze the robustness of gradient-based optimization algorithms under disturbances. We show that, under mild assumptions, these algorithms converge to a small neighborhood of the optimal solution, provided that the perturbations remain bounded and sufficiently small.

In addition, we highlight the power of learning in controller design, especially for time-delay systems, where computing optimal controllers is challenging even when accurate models are available. In such settings, we develop a direct data-driven approach that learns optimal controllers directly from data. Finally, we demonstrate the effectiveness of learning-based control through applications in robotics.

Data-Driven Discovery and Prediction of Wildfire Impacts on Fluvial Networks

Ricardo Gonzalez-Pinzon, University of New Mexico

Wednesday, March 11, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

Wildfires are increasingly generating large-scale hydrologic and biogeochemical disturbances that propagate through river networks, altering runoff regimes, sediment transport, and nutrient export over hundreds of kilometers. Despite expanding sensor deployments and public datasets, scalable integration frameworks and generalizable predictive models for post-fire impacts remain limited. In this seminar, I present three computational products that address this challenge: RIO-FINDER, TIERRAS, and a multilayer perceptron (MLP) surrogate model for solute transport. RIO-FINDER (River Integrated Observations for Fire-Impacted Network Discovery and Evaluation in R) is an open-source geospatial framework that links four decades of wildfire perimeters (MTBS) with high-resolution hydrologic observations (USGS NWIS) through the NHDPlus stream topology. It performs large-scale spatial intersection analyses to identify monitoring sites embedded within fire-affected basins, enforce burn-percentage thresholds, and filter for sites with both pre- and post-fire observations. The result is a CONUS-scale inventory accessible through an interactive Shiny interface, along with a rapid-analysis tool for newly burned watersheds. Complementing this discovery framework, TIERRAS (Tracer Injection Experiments in Rivers and Streams) is a curated database of conservative solute transport experiments spanning diverse hydrogeomorphic settings. The dataset consolidates tracer breakthrough curves (BTCs), standardizes heterogeneous metadata, and augments observations with physically consistent synthetic solutions of the advection–dispersion equation. Building on TIERRAS, we develop a pretrained MLP model that predicts breakthrough curves without site-specific calibration, leveraging synthetic pretraining and fine-tuning on experimental data to achieve robust cross-site generalization. Together, these tools form an end-to-end pipeline for scalable discovery, data fusion, and machine-learned forecasting of wildfire-driven disturbances across continental-scale fluvial networks.

Strategies to Suppress and Correct Noise in Quantum Systems

Milad Marvian, University of New Mexico

Wednesday, February 25, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

The susceptibility of quantum systems to noise remains a major obstacle to realizing their full potential for computational tasks.  While the threshold theorem guarantees that arbitrarily long quantum computations can be performed reliably provided each component's noise level remains below a certain threshold, meeting the overhead and noise-level requirements poses significant technological challenges.  In this talk, I will review some recently developed strategies to suppress and correct quantum noise. I will discuss easy-to-implement techniques such as randomized dynamical decoupling and energy-penalty error suppression to reduce the noise on each qubit, as well as design principles for low-overhead fault-tolerant quantum circuits.

Exploring Unanticipated Functionality in the Mobile Ecosystem and Beyond

Kevin Butler, University of Florida

Wednesday, February 18, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

Telecommunication networks form the backbone of our connected society, enabling global voice and data communication. Yet, beneath their seamless operation lies a complex interplay of signaling protocols, legacy systems, and evolving technologies that, over the decades, have exposed both opportunities for innovation and significant security challenges. While these networks have changed over the past 50 years and complexity has migrated outwards to devices, one enduring challenge has been a lack of accessibility. This talk will cover our efforts to better assess security in the mobile device ecosystems, from platforms to core cellular infrastructure. The theme of unanticipated functionality - and the consequences of such functionality on users - is common in security. I will discuss this theme in the context of marginalized and vulnerable users, whose security needs have been largely unaddressed, and offer some thoughts on emerging security challenges for computer systems and users.

Trustworthy AI and Autonomy: A Formal Methods–Driven Approach

Pavithra Prabhakar, University of New Mexico

Wednesday, February 11, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

Autonomous and cyber-physical systems (CPS) integrate software tightly with physical processes and are increasingly deployed across a wide range of application domains. Modern autonomous CPS depend critically on AI-enabled components for perception, control, and decision making, especially machine-learning and neural-network–based methods. In safety-critical settings—such as aerospace, robotics, and autonomous transportation—failures of these components can have catastrophic consequences, making a high level of trustworthiness essential.

Our lab conducts research on the rigorous analysis and assurance of AI-enabled autonomous systems using formal methods, a class of mathematically rigorous techniques. We advocate abstraction as a foundational principle for addressing the inherent scalability challenges posed by high-dimensional AI models and their interaction with continuous physical dynamics. By constructing sound, yet computationally tractable abstractions, we enable formal verification and validation of system-level safety, stability and correctness properties.

We demonstrate the effectiveness of this approach through multiple real-world case studies, including the verification of neural networks used in collision-avoidance protocols and autonomous rocket-landing systems, among others. These examples illustrate how formal methods can deliver strong, mathematically grounded guarantees for AI-based autonomy, advancing the development of trustworthy, reliable, and deployable autonomous CPS.

Enabling Human-centered Machine Automation with Bi-directional Teaming Integration of Dynamics using Immersive Digital Twins

Fernando Moreu, University of New Mexico

Wednesday, January 28, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

This seminar challenges the term automation in the context of engineering experiments and vibrations, proposing new human-computer interfaces and human-in-the-loop control paradigms. Applications include using Augmented Reality (AR) systems enabling a standalone human interface with Digital Twins (DT) for automatic defect detection and non-linear characterization of vibratory systems. Applications include industrial human-centered machine-enabled inspection with applications for smart manufacturing DT. Applications of this new machine-aided DT inspection employs a nonstationary pixel unit conversion with an automated image conversion translating anomalies to engineering units in the eyes of the inspector. The proposed interface with DT also enables intuitive robot programming adjusting the kinematic controller’s parameters with application for construction, manufacturing, and field inspections. The practical application and validation of the model is examined through experiments involving human upper limb movement in interaction with robots. This immersive AR interface opens a bi-lateral communication line between humans and robots for collaboration and bi-directional DT teaming. Ongoing practical applications include the use of neuromorphic, low-latency system identification for non-linear systems ID, and human-robot construction teaming with the help of AR DT.

The Hidden Cost of Convenience: Privacy Risks in Everyday Online Systems

Afsah Anwar, University of New Mexico

Wednesday, January 21, 2026, 2:00 PM

Location: Larrañaga Engineering Auditorium (Centennial 1041)

Abstract:

Digital service providers often prioritize frictionless user experiences by adopting technologies that simplify access to their services. One widely used mechanism is the Short Message Service (SMS), which delivers links (URLs) that enable single-click access to online services with minimal user effort. However, SMS is inherently insecure, and numerous studies and incident reports have documented message interception and data leakage. As a result, placing excessive trust in this insecure channel creates opportunities for unintended access and adversarial exploitation. This talk will present investigation techniques for identifying and analyzing the privacy implications of SMS-delivered URLs. Particularly, we will focus on Personally Identifiable Information (PII) exposures and examine their root causes, including weak authentication models and insufficient authorization controls employed by digital services. Additionally, we will explore how such PII leaks can affect users beyond those directly exposed, as well as how service-side over-fetching of sensitive data amplifies privacy risks.
