LA JOLLA (Aug 14, 2024)—The Salk Institute will welcome immunologist Jamie Blum as a NOMIS Assistant Professor in September 2025. Blum investigates how the immune system interprets what we eat—specifically, why some foods trigger harmful allergic responses while others are accepted as safe.

With support from the NOMIS Foundation, Blum’s lab at Salk will continue to explore how immune cells identify and respond to food compounds. While traditional food allergy research focuses on the molecules involved in allergic reactions, Blum’s lab is taking a new approach by exploring the mechanisms of oral tolerance, the immune system’s default, non-inflammatory reaction to most foods. By understanding the signals that help our bodies tolerate most foods, Blum’s work could enable entirely new immunotherapy strategies for preventing or treating food allergies.

“Jamie is an innovative thinker whose work is redefining what we know about food allergies and the relationship between diet and the immune system,” says Salk President Gerald Joyce. “Her discoveries are opening a new frontier in immunotherapy and nutrition science. She will be a great addition to the immunology, plant biology, and molecular science communities here at Salk.”

Food allergies are on the rise globally, yet much remains unknown about how and why they develop. Most of what scientists currently understand about food tolerance comes from a limited number of studies on a single protein in eggs. Blum is working to change that. She has already discovered new compounds in staple crops, including corn, wheat, and soy, that help the immune system learn to tolerate these foods. Interestingly, the mechanism for developing tolerance to these foods seems to differ from what’s known about eggs, highlighting the need for more research on this topic. Blum’s ultimate goal is to map the molecular signals that determine whether the body accepts or rejects a food and use that knowledge to inform future therapies for allergy and autoimmune conditions.

“The fact that most of us can eat without adverse immune reactions is something we take for granted,” says Blum. “But tolerance isn’t passive. It’s a highly orchestrated response. We’re trying to understand the cues that shape that response—what molecules are involved, and what context the immune system needs to ‘see’ food as safe.”

Blum earned her PhD in molecular nutrition from Cornell University and completed her postdoctoral training at Stanford University, where she combined immunology, plant biology, and chemical engineering to study the immune system’s interaction with food at the single-cell level. Her research uses cutting-edge tools, including high-throughput T cell receptor screening, antigen mapping, and in vivo tracking of immune responses in mouse models.

Blum’s work has earned her a Life Sciences Research Foundation Fellowship and support from the National Science Foundation. As a NOMIS Assistant Professor, she will continue pushing boundaries in fundamental immunology while laying the groundwork for new therapeutic and plant-based strategies to address food allergies.

AUTOMOTIVE IoT

Worcester Polytechnic Institute selected as key partner in national cybersecurity and AI training initiative to advance U.S. automotive innovation




$2.5 million DRIFT program aims to close critical talent gaps and safeguard the future of connected vehicles



Worcester Polytechnic Institute





Worcester Polytechnic Institute (WPI) has been named to a select group of academic institutions leading a nationwide effort to strengthen cybersecurity and artificial intelligence (AI) capabilities in the U.S. automotive industry—a sector increasingly reliant on smart, connected technologies. 

Supported by a $2.5 million grant from the National Centers of Academic Excellence in Cybersecurity  the DRiving Automotive Industry WorkForce Transformation (DRIFT) program will provide specialized online and in-person training designed to upskill the workforce and protect vehicle systems from emerging threats. 

WPI associate professors Jun DaiXiaoyan Sun, and Xiaozhong Liu, all from the Department of Computer Science, will lead the university’s DRIFT program. WPI will receive $749,994 over two years, with the opportunity for an additional $300,000 in a third year. The program will offer tuition-free modules, workshops, and real-world training to help engineers and professionals develop advanced competencies in cybersecurity and AI. 

“Today’s vehicles are computers on wheels—powered by data, software, and smart systems,” said Dai. “AI is transforming the future of mobility, but without robust cybersecurity, we put innovation—and lives—at risk. DRIFT directly addresses the workforce gap by preparing engineers and professionals with the tools they need to protect connected and autonomous vehicles, and ultimately, to accelerate the development of next-generation transportation.” 

As vehicles become more connected, equipped with internet-enabled infotainment systems, GPS, remote diagnostics, and automated driver assistance systems, they also become more vulnerable to cyberattacks. While autonomous vehicles are often in the spotlight, nearly all modern vehicles are now potential targets. 

In one of the most publicized demonstrations of this risk, cybersecurity researchers remotely took control of a Jeep Cherokee in 2015, manipulating its brakes, steering, and transmission while it was on the highway. More recently, the 2025 Global Automotive and Smart Mobility Cybersecurity report by Upstream revealed that massive-scale incidents—each impacting millions of vehicles—more than tripled between 2023 and 2024, rising from 5% to 19%. The data shows the vulnerability of even top-tier smart vehicles. These incidents underscore the urgent need to secure both automotive systems and the talent pool capable of doing so. 

The DRIFT curriculum is designed for a wide audience, including: 

  • Automotive engineers 
  • Cybersecurity and AI professionals 
  • IT workers transitioning into transportation-related sectors 
  • Educators and students at two- and four-year institutions 
  • Department of Transportation personnel 
  • Military and civilian defense staff 
  • First responders and public safety officials 
  • Policymakers and regulators 
     

Courses will be delivered online, in-person, and hybrid formats and will cover: 

  • The architecture and key components of connected and autonomous vehicle (CAV) systems 
  • AI applications and their role in enabling core CAV functions 
  • Common vulnerabilities in connected vehicle systems, including GPS spoofing, sensor interference, and over-the-air update threats 
  • Defensive cybersecurity strategies tailored for CAV environments 
  • Hands-on case studies to bridge theoretical knowledge with real-world applications 
     

WPI joins the following partner institutions in offering DRIFT training:

Add cybersecurity to the list of 21st century expertise and research happening in Pittsburgh.

On Tuesday, August 12, 2025, the University of Pittsburgh Cyber Energy Center and Pitt Cyber hosted “Transforming Cybersecurity: A Multidisciplinary Approach to Risk, Technology, and Policy.” The in-person, day-long workshop brought together experts from across industries and disciplines to assess the current state of cybersecurity through a multidisciplinary lens.

More than 40 participants attended the workshop held at Pitt’s University Club in Oakland. During keynote addresses, panels, and an interactive discussion, they explored emerging technologies and the intersection of technology and policy.

“As the current cybersecurity landscape evolves and grows increasingly complex and costly, the need to bring together experts and stakeholders from across fields could not be greater,” said Erica Owen, Associate Professor in Pitt’s School of Public and International Affairs. “This workshop underscored the value of bringing those perspectives together.”

Cheri Caddy, Senior Cybersecurity Fellow at the McCrary Institute for Cyber and Critical Infrastructure Security, and Greg Shannon, Chief Cybersecurity Scientist at the Idaho National Laboratory, provided the keynote addresses.

Caddy, who has also served in governmental roles such as Senior Advisor for Cybersecurity for the U.S. Department of Energy and as Director of Cybersecurity Policy on the National Security Council, opened the event with her talk “Transforming Cybersecurity.” She highlighted the persistent challenges of a siloed approach to cybersecurity and espoused a more unified ecosystem that brings together parties in and outside of government. She discussed the importance of shifting cybersecurity efforts to “left of boom” (acting proactively, before an attack happens) and the need to adopt a joint private-public model for risk reallocation.

Shannon, in his talk “New Horizons in Cybersecurity and Risk,” discussed current attitudes toward risk and the potential and the challenges of certified software and formal methods (a mathematical approach to verifying software) to help build more secure systems. In addressing the emerging role of artificial intelligence (AI) in developing software, he stressed its potential and risk as well as the need for both slow and fast thinking.

“At the Cyber Energy Center, our work is guided by the question, ‘What if we change cybersecurity by a tall order?’” said Daniel Cole, Associate Professor of Mechanical Engineering and Materials Ccience and Director of the Cyber Energy Center. “Finding that answer won’t happen overnight and, as Cheri and Greg both expressed in their keynotes, it won’t happen in a silo. That’s why this multidisciplinary approach is so essential.”

In addition to the keynote addresses, the workshop included two panel discussions. The first, “Perspectives on Risk,” featured Derek Brown, Director of Cybersecurity and Infrastructure at EQT; Jim Gillespie, Co-founder and Chief Growth Officer of GrayMatter; Mark Hairston, General Industries Practice Leader at Seubert & Associates; and moderator Sarah Scheffler, Assistant Professor of Engineering and Public Policy at Carnegie Mellon University. The panelists from across the energy, technology, and insurance industries shared their unique perspectives on risk and how companies and organizations approach cyberattack prevention. 

The second panel, “Certification and Policy,” was chaired by Cheri Caddy and featured panelists Chad Heitzenrater, Senior Information Scientist at RAND PittsburghZia Hydari, Assistant Professor of Business Administration at Pitt; and Samuel Perl, Senior Member at Carnegie Mellon’s Software Engineering Institute. They explored the intersection between public policy and technology, discussing the complexity of certifying software, the challenges of developing policy as technology rapidly evolves, and role of regulation in the U.S. and worldwide.

The workshop concluded with an interactive discussion titled “Designing the Future of Cybersecurity.” Robert Cunningham, Vice Chancellor for Research Instructure at Pitt, led the session, in which participants identified and discussed key themes from the workshop and charted a path forward for future multidisciplinary collaboration.

“We are grateful for Pitt Cyber’s generous funding and for all the people who helped organize and who participated in this amazing event,” said Owen. “This workshop is the beginning of a long-term effort to bring together many voices to build a stronger, safer cyber infrastructure.”

As bacteria become increasingly resistant to antibiotics and other antibacterials, there is a growing need for alternatives. In a study published on August 14th in the open-access journal PLOS Biology, Tobias Warnecke and colleagues from the University of Oxford and the MRC Laboratory of Medical Sciences, United Kingdom, identified untapped antimicrobials produced by archaea, single-celled organisms that make up one of the three domains of life (the other two being bacteria and eukaryotes, the group that includes us).

Microbes are in constant competition for space and resources and have developed various chemical weapons to fend off other microbial species. All of our antibiotics originally came from these defense systems, though historically, researchers have only investigated the arsenals of bacteria and fungi. There are over 20,000 species of archaea, and these cells often live surrounded by even more numerous bacterial species. The researchers predicted that to survive, the archaeal cells must have ways to compete with the bacteria, representing an unexplored trove of antimicrobials.

The researchers surveyed the genomes of over 3,700 species of archaea, looking for genes encoding proteins that could possibly be wielded against bacteria. They focused specifically on proteins that can cut the molecule peptidoglycan, an essential part of the cell walls of bacteria. The large majority of archaea don’t have peptidoglycan, so these proteins would only be necessary for microbial warfare.

These proteins were present among 5% of the archaeal species surveyed, with some species having multiple types. In the lab, the researchers tested the efficacy of some of the proteins and found that they successfully killed bacteria. They also studied the proteins’ structures, which indicated many were deployed outside of the cell, and some archaea even had components for an injection system that might directly deliver the deadly proteins to competing bacteria.

Much still remains to be discovered on how these molecular weapons may be used in the wild. The peptidoglycan-cutting proteins also represent only one type of antibacterial among many others that may be present among diverse species of archaea.

Warnecke notes, “Archaea are their own Domain of Life, different from bacteria, and different from eukaryotes (humans, plants, flies, etc.). We know very little about their social lives, including how they interact with their ubiquitous brethren - bacteria.

Warnecke adds, “Our work sheds new light on the social lives or archaea and has implications for how we understand microbial communities. It also suggests that archaea might be a large, untapped reservoir for discovering novel antimicrobials in the future.”

Romain Strock, first author, adds, “Archaea are often depicted as either lone extremophiles or syntrophic partners. Our research depicts another, darker side to their social life.”
