NSF CAREER Awards Fuel Bold Research on Resilient Networks, Next-Gen Chips and Security

Five early-career faculty members at The University of Texas at Dallas have received 2026 Faculty Early Career Development Program, or CAREER, awards from the U.S. National Science Foundation, securing a combined multi-million-dollar investment in research that spans resilient computer networks, next-generation semiconductor electronics, software security and the mathematical foundations of complex systems. The CAREER program is one of the foundation’s most prestigious forms of support for junior faculty, providing five years of funding that pairs a sustained research agenda with an explicit commitment to education and mentorship. The new UT Dallas awardees, all assistant professors, reflect that dual mission: each project couples technical ambition with structured opportunities for undergraduate and graduate students to participate in discovery.

The five recipients are Dr. Waseem Abbas, assistant professor of systems engineering; Dr. Sourav Dutta, assistant professor of electrical and computer engineering; Dr. Kirill Lazebnik, assistant professor of mathematical sciences; Dr. Kyle McCall, assistant professor of materials science and engineering; and Dr. Xinda Wang, assistant professor of computer science. Four of the five, Abbas, Dutta, McCall and Wang, are members of the university’s Erik Jonsson School of Engineering and Computer Science, while Lazebnik belongs to the School of Natural Sciences and Mathematics. The portfolio of funded work illustrates how the CAREER mechanism can seed progress across the full stack of modern technology, from the atoms inside a transistor to the mathematical abstractions that describe dynamical behavior and the code that keeps the world’s software infrastructure safe.

University research leadership framed the awards as evidence of the institution’s growing strength in areas that will define the coming decades of technology. “From resilient networks and advanced semiconductors to artificial intelligence, cybersecurity and fundamental mathematics, these researchers are tackling complex challenges with the potential to shape the technologies and systems of the future,” said Dr. Joseph Pancrazio, vice president for research and innovation and professor of bioengineering. He emphasized that the awards also recognize the recipients’ commitment to integrating research and education, giving students the chance to learn through hands-on discovery and helping cultivate the next generation of researchers and innovators. That educational component is not incidental to the CAREER program; it is a core evaluation criterion, and each of the five UT Dallas projects embeds training, outreach or curriculum development alongside the technical work.

Dr. Waseem Abbas received a five-year award of $514,916 to confront one of the most consequential questions in networked engineering: what happens when a system designed to absorb disruption is hit by something worse. Robot teams, infrastructure networks and distributed computing systems, in which tasks are shared across many devices, are typically engineered with a certain tolerance for failure built in. If an attack, fault or environmental disturbance stays within that expected envelope, the system degrades gracefully. But when the disruption exceeds the threshold, performance can deteriorate rapidly and unpredictably, sometimes collapsing in ways that cascade through the entire network. Abbas aims to develop networked systems that adapt as conditions worsen, so that performance declines smoothly rather than failing catastrophically. A second strand of his research seeks to identify the most critical connections and components within a network, the nodes and links whose protection yields the greatest resilience. By concentrating defenses on those essential elements, operators could maintain core functions without paying for costly, blanket redundancy across every part of the system. The work has obvious implications for autonomous vehicle coordination, industrial automation and the distributed computing fabric that increasingly underpins everyday services.

Dr. Sourav Dutta’s award, totaling $501,234, targets the physical bottleneck that threatens to slow the artificial intelligence revolution: the semiconductor itself. As AI models and autonomous systems generate staggering volumes of data, conventional computer chips struggle to move information efficiently between the separate regions where data is stored, processed and transmitted. Every transfer across those internal distances costs energy and time, and at the scale of modern workloads the cost becomes prohibitive. Dutta will investigate ultrathin oxide semiconductor transistors with a property that could prove transformative: they can be manufactured at low temperatures and stacked vertically on top of conventional silicon electronics. Vertical stacking would shorten the distance data must travel, directly reducing energy consumption and potentially enabling faster, more efficient chips. Because the low-temperature fabrication process is compatible with existing silicon technology, the approach could be integrated with current manufacturing rather than requiring an entirely new industrial base. Dutta also plans to apply artificial intelligence and computational modeling to predict how candidate transistors will perform before they are built, accelerating design cycles and shrinking the optimization process that normally stretches across years of laboratory iteration.

On the software side of the engineering school, Dr. Xinda Wang received $617,397 to build AI tools that can help open-source software communities catch security vulnerabilities earlier, at the moment developers are making changes to code. Open-source software, assembled from publicly available code that anyone can inspect, contribute to or reuse, has become the invisible backbone of the digital world. It powers commercial products, government systems and critical infrastructure alike. That ubiquity carries a hidden risk: when a vulnerability exists in a widely used open-source component, it silently propagates into every downstream system that incorporates the original code, multiplying the potential blast radius of a single flaw. Wang’s team will train machine-learning systems to recognize patterns in how code changes are made and how those changes ripple through other parts of a software project, flagging suspicious modifications before they are merged and deployed. Just as importantly, the researchers will develop AI models capable of explaining why a particular change may pose a security risk. That explanatory capability matters because security teams and volunteer maintainers often operate with limited time and resources; a tool that simply raises an alarm without context is easily ignored, while one that articulates its reasoning can be trusted and acted upon.

The fourth engineering awardee, Dr. Kyle McCall, received the largest of the five grants, $796,646, to probe a question that sits at the frontier of materials science: how the local atomic structure of emerging semiconductor materials determines their properties and their potential in electronics and energy technologies. Many of the most promising new materials exhibit unusual behavior that arises from deviations of atoms away from their ideal, expected positions within the crystal lattice. These local structural distortions can dramatically alter how a material conducts, absorbs light or responds to electric fields, yet scientists do not fully understand how the deviations can be controlled through the composition and arrangement of the constituent atoms. Compounding the challenge, the distortions are invisible to conventional characterization techniques, which average over large regions and therefore miss the local disorder that matters most. McCall and his team will use total X-ray scattering, a technique sensitive to how atoms are locally bonded within a material, to map the relationship between chemical composition, atomic deviations and resulting properties. The ultimate goal is a set of design principles that researchers can use to create new semiconductor materials with desirable properties on demand. The project also carries an educational mission, providing undergraduates with hands-on research experience and developing educational resources for teachers and students across the Dallas-Fort Worth region.

The lone recipient in the School of Natural Sciences and Mathematics, Dr. Kirill Lazebnik, secured a $450,000 CAREER grant for work in pure mathematics with unusually broad applied reach. His research concerns rational functions, the mathematical objects formed as ratios of polynomials, which serve as fundamental tools for mathematicians, scientists and engineers who model and analyze complex systems. Rational functions appear throughout signal processing, dynamical systems and scientific computing, making advances in their theory potentially consequential far beyond mathematics departments. Lazebnik’s project aims to deepen understanding of the structure of the space of rational functions and to explore how these functions might be applied in additional areas of analysis and dynamics. Questions that sound abstract, such as how the space of such functions is organized and connected, often translate into practical insight for engineers studying stability, control and signal behavior. Like his colleagues, Lazebnik has built education into the heart of the grant, with undergraduate research opportunities and community outreach programs designed to train future mathematicians and widen access to the discipline.

Taken together, the five awards reveal a coherent picture of where foundational research investment is flowing and why. The problems the CAREER recipients have chosen sit precisely at the pressure points of contemporary technology: networks that must survive deliberate attack and random failure, chips that must move data without drowning in their own energy consumption, software supply chains that must be defended at the moment of change, materials whose properties are hidden in atomic-scale disorder, and mathematical structures that underpin our ability to model all of the above. Each project also treats education as an engineering problem in its own right, designing pipelines of trained students, teacher resources and community engagement that extend the impact of the research well beyond the laboratory. For UT Dallas, the sweep of the awards across two schools signals institutional momentum in fields where competition for federal support is fierce. For the researchers themselves, five years of stable funding at the start of an academic career is a rare luxury, the freedom to pursue ambitious, long-horizon questions, and to bring students along for the entire journey from first hypothesis to published result.
