Amazon-Virginia Tech initiative awards two Amazon Fellows, support for four faculty projects


Faculty awards

Additionally, four faculty members received funding through the initiative for their projects. 

Muhammad Ali Gulzar, assistant professor in the Department of Computer Science, received funding for “Foundations on the Code Comprehensibility of Large Language Models.” LLMs have demonstrated strong performance in code generation. With the rise of agentic LLMs, their use is rapidly expanding into post development tasks requiring a deeper semantic understanding of code that is not strictly rooted in lexical and syntactic code features. While popular LLM benchmarks measure the accuracy of LLMs’ code generation, the extent to which LLMs truly understand code remains largely unevaluated. This project seeks to design a scalable, quantitative, and automated method for assessing how well an LLM understands code and the impact of this understanding on post-development tasks. The goal is to encourage more mindful use in coding tasks and, in the long run, provide an actionable basis for prioritizing training data for LLM fine-tuning.

Ming Jin, assistant professor in the Bradley Department of Electrical and Computer Engineering, received funding for “Enhancing Foundation Model Reasoning through Reinforcement Learning with Novel Reward Design.” Current efforts to enhance foundation model reasoning face limitations like high compute costs; reward hacking and stability issues with learned reward models; difficulty balancing reasoning quality and efficiency; and challenges in multimodal contexts. Improving complex reasoning of foundation models reliably and efficiently is critical for Amazon’s AI ecosystem. Producing both critiques and actionable hints for a richer signal has shown promise for improving optimization efficiency and effectiveness in previous research. This proposal builds on this foundation by designing novel reward signals that guide a model’s reasoning process, transforming it into a more autonomous agent capable of tackling complex, multi-step problems. 

Chang-Tien Lu, professor in the Department of Computer Science and associate director of the Sanghani Center, received funding for “Privacy-Preserving Collaborative Reasoning in Multi-Agent Systems.” Multi-agent systems enhance performance by combining a weaker but locally accessible model with a more powerful yet proprietary black-box remote model. This combination exposes local data to a remote agent, raising concerns about information leakage, especially in sensitive domains like healthcare information, financial records, and e-commerce activities. For virtual assistants like Amazon Alexa and smart home systems, which frequently process sensitive user data, robust local data protection is also crucial for preserving user privacy and trust. The goal of this research is to design a collaborative reasoning mechanism without exposing sensitive local data to thoroughly protect it before the black-box model inference.

Tu Vu, assistant professor in the Department of Computer Science, received funding for “Efficient Model Development through Fine-tuning Transfer.” Large Language Models are continually evolving, with newer versions released to improve pretraining quality, architecture, or alignment. Yet each new version of the base model typically demands repeated and computationally expensive alignment procedures. This inefficiency extends to domain- or language-specific models, where fine-tuning must be redone from scratch with every base model upgrade. Transferring fine-tuning updates (i.e., weight differences or “diff vectors”) across model versions offers a compelling alternative: enabling model updates without full retraining. This proposed approach promises to significantly reduce training costs while maintaining competitive performance, making it a viable strategy for sustainable LLM development.

About the workshop

The invitation-only AI workshop was held in Ocotber at Academic Building One in Alexandria and included remarks by Lance Collins, vice president of the greater Washington, D.C., area; Ramakrishnan; and Anand Rathi, center liaison and director, software development, artificial general intelligence, at Amazon. 

“We are pleased to welcome our Amazon collaborators to Virginia Tech’s new Academic Building One in Alexandria for our annual gathering,” Ramakrishnan said. “It is a great opportunity to connect Virginia Tech faculty in the space of AI with Amazon researchers and foster future collaborations.”  

“Our collaboration with Virginia Tech represents a strategic investment in developing the next generation of AI talent and innovation,” said Rathi. “The research emerging from this partnership continues to advance our understanding of responsible and efficient AI systems while preparing students for the complex challenges of tomorrow.”

Additionally, Chalapathi Choppa, senior manager, security engineer, Amazon, discussed Amazon Artificial General Intelligence and the importance of responsible AI, and two Virginia Tech faculty members who have sponsored research projects with Amazon gave lightning talks. They were:

Whitley’s Peanut Factory Marks 40 Years with an Eye on Virginia’s 250th Celebration | Williamsburg Yorktown Daily

GLOUCESTER — What began as a small kitchen experiment has grown into a staple of Virginia’s peanut industry. This year, Whitley’s Peanut Factory is celebrating its 40th anniversary, marking four decades of family tradition, innovation, and steady growth in Gloucester.

For owner Todd Smith, the milestone is both personal and professional.

“We’re doing something right,” Smith said. “The quality of the product and great customer service, those two things have carried us for 40 years.”

The company officially launched in 1986, though its roots trace back to Smith’s upbringing in the peanut business. His father worked closely with farmers supplying seed peanuts, giving Smith early exposure to an industry that would later define his career.

The idea for the business came from a homemade recipe.

“My dad used to cook these peanuts in our kitchen,” Smith said. “We decided to try it commercially, put them in a can, and see if we could sell them.”

Starting with a small retail store, a single cooker, and just a few employees, the company has since expanded into a multi-location operation. Today, Whitley’s employs dozens of workers, particularly during the busy holiday season when demand peaks.

Despite its growth, the company has remained committed to its original process.

“We’re doing the same thing today that we did 40 years ago, just on a bigger scale,” Smith said.

That consistency has been key to maintaining the brand’s identity and loyal customer base. At the same time, the company has found ways to evolve without compromising quality.

Remaining in southeastern Virginia has been essential to the company’s success. The region is known for producing Virginia peanuts, a variety prized for its size and flavor.

“We’re close to where the peanuts are sourced,” Brett Smith said. “That’s always been important.”

Over the years, Whitley’s has also become a significant employer in Gloucester. During peak seasons, the company employs around 90 people, contributing to the local economy and providing long-term opportunities for many workers.

As Whitley’s celebrates 40 years, the focus is also on what comes next. Todd Smith hopes to eventually pass the business on to his son, who joined the company five years ago.

“The goal is for him to take over and carry on the legacy,” Smith said.

Brett Smith sees both opportunity and challenge ahead.

“The world is changing fast,” he said. “It’s about adapting to that while staying true to what’s made us successful.”

The company’s 40th anniversary comes at a unique time for the Commonwealth, as Virginia prepares to celebrate its 250th anniversary. For Whitley’s, the overlap adds another layer of meaning to the milestone.

To mark both occasions, the company has introduced commemorative packaging and is participating in local events and festivals tied to the anniversary, particularly in historic areas like Williamsburg and Yorktown. From community gatherings to major seasonal celebrations, Whitley’s is using the moment to highlight both its own history and Virginia’s broader story.

“It’s kind of the bigger picture,” Brett Smith said. “We’re proud of 40 years, but 250 years is pretty incredible.”

As Virginia reflects on its past, Whitley’s Peanut Factory is celebrating its own legacy, while positioning itself to remain part of the state’s future for years to come.

Lauren Hurst commits to Virginia Tech out of transfer portal, joining Alyssa Latham


Former Lady Vols basketball guard Lauren Hurst committed to Virginia Tech out of the transfer portal on April 11, making her the second Tennessee player to join the Hokies.

Former Tennessee forward Alyssa Latham committed to Virginia Tech as a graduate transfer on April 1.

Latham and Hurst were part of the mass exodus from the Lady Vols that left no returners on the team. All eight players with eligibility left entered the transfer portal, and five-star forward Oliviyah Edwards was released from her signing, leaving four-star wing Gabby Minus as the only incoming freshman.

Both Latham and Hurst were key players in Tennessee’s rotation by the end of the season. Latham spent two years with the Lady Vols after transferring in from Syracuse and was one of a handful of returners from coach Kim Caldwell’s first season.

Latham was one of four forwards on Tennessee’s roster – the other three graduated – and averaged 19.1 minutes this season. The 6-foot-2 junior averaged 4.7 points, 3.4 rebounds and one steal while shooting 53.9% from the field this season.

Hurst broke into the rotation in the second half of the season, and she was Tennessee’s most accurate 3-point shooter. The 6-foot-3 guard led the team in 3-point percentage, hitting 41.4% on 1.2 attempts from 3-point range.

The Cleveland, Tennessee, native averaged 2.3 points, 1.6 rebounds and 10 minutes per game on the season, and she shot 48.8% from the field. Hurst played a season-high 24 minutes at Ole Miss, when she scored a career-high 16 points on 6-for-9 shooting, including 4-for-5 on 3-pointers.

Hurst was part of a five-player 2025 class ranked No. 2 in the nation by ESPN, UT’s highest-ranked class since 2017. She was a four-star prospect ranked No. 45 in the class.

‘Don’t Fairfax Me’: How Virginia’s largest county became center of antiredistricting campaign – WTOP News


Signs that say, “Don’t Fairfax Me” and “Vote No” are appearing in rural parts of Virginia in opposition to gerrymandered maps being voted on in a special election.

‘Don’t Fairfax Me’: Northern Virginians fight redistricting plan

As the special election that will determine the fate of a plan to redraw Virginia’s congressional districts approaches, the state’s largest jurisdiction has started being referenced as a verb in messaging opposing the initiative.

Signs that say, “Don’t Fairfax Me” and “Vote No” started appearing in rural parts of Virginia, Cardinal News reported. And on social media, Del. Wren Williams, whose district includes several counties in the southwestern portion of the state, defined “Fairfaxphobia.”

Early voting has been underway for weeks, but on April 21, voters will decide whether to OK a plan that would redraw Virginia’s congressional map. Currently, the state has elected six Democrats and five Republicans across its 11 districts. The proposed map could give Democrats a 10-1 advantage, experts say.

Virginia Democrats argue the step comes in response to President Donald Trump’s push for redistricting in Republican-led states. Republicans have been critical of the effort.

Williams is describing “Fairfaxphobia” as a fear that political power concentrated in Fairfax County will make decisions for the whole state and create policies impacting some communities that they can’t afford.

“We don’t want to be Fairfax County,” Williams told WTOP. “We don’t want skyscrapers. I don’t want to have to go somewhere outside and walk around to find some patches of grass to touch. I am interested in rural life, a little bit easier, a little bit simpler, a little bit more laid back, not as fast paced.”

As part of the proposed map, Williams said, “at least five districts run up and split up Fairfax County, which will eventually lead to five sitting congressional members from the county of Fairfax, and that’s just not representative of the entirety of the commonwealth.”

Jeannette, a longtime Northern Virginia resident, said people who live in the northern part of the state “are seen as an anomaly, maybe to the rest of Virginia, given our, I think, collective more liberal leaning. And I understand why they’re saying that, but I think we should separate that from the goal of the referendum.”

Dave Lincoln, meanwhile, said Friday he hadn’t heard about the signs in rural parts of the state but, “I guess it’s — we are what we are.”

Senate Majority Leader Scott Surovell called the campaign disappointing, because “Fairfax County does a lot for the entire state. If it wasn’t for Fairfax, our state would have the economy of Mississippi.”

The “Don’t Fairfax Me” signs say they’re paid for and authorized by a political action committee called “New Vision VA.” Dominion Energy made a $25,000 donation to the PAC, according to the Virginia Public Access Project.

Yves Fischer, who lives in Alexandria, said the messaging and advertising on the redistricting referendum are confusing.

For Tiffany, “I guess they’re saying ‘Don’t Fairfax’ Virginia, because obviously we are a much more educated, classy, professional, employed area, and we, of course, are going to vote ‘yes’ on this.”

In Springfield on Friday afternoon, Ann said she hadn’t seen or heard about the signs, but, “It should be a big ‘no.’ It’s not right. It’s not fair to most Virginians.”
