By making AI and machine learning education more accessible, we hope to inspire fresh perspectives that will shape the industry’s future.”
A Diverse Background Marked with Achievements
Prior to founding Neumann Nexus, Katherine served as a scientist at the U.S. Air Force, Army, and NASA. When Katherine was working at the Air Force, she was part of the team that operationalized the “cognitive malware effect.” She describes this phase as a pivotal moment in her journey, as it ignited her interest in cognitive engineering and human factors for her Master’s, where she studied the effects of user-avatar characteristics on perceptions of performance.
Later, for her PhD, Katherine introduced a new sub-specialization in the field of psychophysics, called lunar psychophysics, and founded the Lunar Psychophysics Virtual Reality Laboratory at the Catholic University of America (CUA). In her five years as a doctoral research fellow for the U.S. Army, she developed assessments for Command Climate that are still in use across U.S. military services. She points out that her role also included evaluating unit-level behavioral performance across installations in the U.S. to identify the causes of poor performance. “I often worked directly with battalion commanders to pinpoint issues, even when the root cause was leadership itself,” she adds. These experiences shaped her moral compass. They also taught her how to advocate for individuals in complex and high-stakes operational environments.
During her post-doctoral research in Industrial Engineering at the University of Central Florida (UCF), Katherine continued advancing her psychophysics research, exploring how human performance and perception could be modeled in Martian environments. This research received awarded recognition from NASA, leading to her role as the Senior Scientist for the Chief Scientist Office of NASA’s Human Research Program. There, she oversaw grant solicitations contributed to groundbreaking work on human health countermeasures, space radiation biology, and long-duration spaceflight analogs. This period cemented her systems-thinking approach, where every element — technical, behavioral, and operational — fits into a larger whole.
Katherine’s diverse background has shaped her leadership approach at Neumann Nexus. Early in her career, Katherine learned the importance of interdisciplinary collaboration. She points out that engineers, scientists, and visionaries must come together to tackle humanity’s most complex challenges, whether in military operations, virtual reality, or space exploration. This spirit of collaboration has remained central to her work, especially in high-pressure scenarios – from supporting warfighters and pilots to solving problems beyond low-Earth orbit. Katherine’s work in psychophysics, human performance in space, VR, neuro-ergonomics, counterintelligence, and organizational climate has further laid the foundation for her career. It continues to inform her approach to innovation and leadership.
“I rely on the lessons from my diverse career to guide us in tackling challenges with creativity, discipline, and a shared commitment to excellence,” she adds.
The Launch of Neumann Nexus
During her years of research in psychophysics and cognitive engineering, Katherine realized that they were standing at the “threshold of a new renaissance” in human-machine interaction. This realization led her to establish Neumann Nexus.
“Like Vannevar Bush envisioned with his Memex, or Doug Engelbart with his ‘augmenting human intellect’ mission, I recognized the need for AI to be developed not just as a tool that automates tasks, but as a technology that, when carefully and ethically designed, can responsibly enhance human capabilities and understanding,” Katherine says.
She describes her time at NASA as transformative. For her, it offered both the excitement of innovation and eye-opening clarity about the potential of human-AI interaction. “In the pursuit of pushing human boundaries beyond Earth, I witnessed firsthand the dance between human intuition and machine precision,” Katherine says. She also observed a persistent misalignment across both the private and public sectors in the industry. “I sometimes found organizations were often racing to implement AI solutions without fully considering their harmony with human values and cognitive patterns.”
“They operated on different wavelengths than the human mind,” Katherine explains, “like trying to compose a duet between a quantum computer and a Stradivarius — each magnificent in its own right, but unable to sync without thoughtful orchestration.”
“This cognitive dissonance, coupled with my deep-seated passion for advancing human potential, became the intellectual catalyst for Neumann Nexus,” she adds.
Katherine and her team are drawing inspiration from von Neumann’s work on self-replicating systems and the neural basis of computation to create machine-learning and AI systems that don’t just process and produce information but resonate with the rhythms of human cognition and intuition. “Our vision transcends the conventional narrative of AI as a replacement for human capabilities; instead, we see it as a collaborative tool designed to amplify human ingenuity across all domains of achievement,” Katherine says.
The company’s initial mission has evolved beyond technological advancement—it is now about orchestrating a harmony between human intelligence and AI. Katherine explains that they are building bridges between the quantifiable world of computation and the ineffable realm of human insight, a convergence that could fundamentally transform how one solves complex problems, makes decisions, and pushes the boundaries of human potential.
“At Neumann Nexus, we’re not just developing AI systems and recommendations; we’re crafting the future of ethical human-AI partnership, where technology serves as a catalyst for unlocking the full spectrum of human capability, rather than outright replacing it,” says Katherine.
The Vision for Neumann Nexus
At its core, Neumann Nexus is more than just AI – it is about humanity. Katherine’s vision is to redefine the narrative around AI, from one of fear and uncertainty to one of empowerment and collaboration. She believes that when they design technology to complement and amplify human potential, they open the door to extraordinary possibilities.
Looking forward, Katherine sees Neumann Nexus not just as a consulting firm but as a movement – a call to align technology with the values, aspirations, and needs of the people it serves. “Whether it’s optimizing performance in extreme environments, enhancing organizational resilience, or addressing societal challenges, our mission is to ensure that AI serves as a force for good in shaping the future,” she underscores.
Katherine says, “My path to success has been anything but conventional – and I envision the same remarkable trajectory for the future of this company.”
AI-Driven Human Resilience
Understanding human resilience in extreme environments has always been a driving force in Katherine’s research. She informs that one of the most exciting ongoing projects she has carried over from NASA is their collaboration with Justin Packshaw, a world-renowned explorer and CEO of JORO Experiences, alongside researchers at the University of Central Florida. Together, they are using AI to analyze data from a grueling 2,000-kilometer Antarctic expedition, where Justin and his teammate Dr. Jamie Facer-Childs endured sub-zero temperatures, navigated treacherous ice terrains, and survived on foot and by kite for 80 days. Katherine explains that this research is critical for exploring the thresholds of human endurance — physiological, cognitive, and psychophysical. “It’s particularly important for understanding how to improve AI-supported decision-making under extreme stress to optimize decision-making and enhance team resilience in deep-space missions and other high-stakes environments,” she adds.
Two Key Challenges in the AI Industry
In the AI industry, navigating the balance between technological advancement and ethical responsibility continues to be a major challenge, Katherine notes. According to her, there is always a temptation to push the boundaries of what’s possible. She believes it is critical to ensure that innovation aligns with human values. “Early in my career, I learned the importance of embedding ethics into every stage of AI development, from concept to deployment,” Katherine says.
And, according to her, another challenge is the misconception that AI is merely a tool that replaces rather than enhances human potential. It is tough to overcome this misconception, she says. At Neumann Nexus, Katherine and her team focus on human-computer collaboration, and they have had to actively educate stakeholders about the value of augmenting human skills rather than automating them away in every situation. “Overcoming these challenges requires clear communication, stakeholder engagement, and a steadfast commitment to designing systems that prioritize trust and transparency,” says Katherine.
Katherine reveals that their work at the intersection of human factors and AI is uncovering fascinating possibilities. In collaboration with Optimal Cities, they are working to develop systematic urban planning approaches designed to empower individuals to be more aware of areas that contribute to higher health risks. With Bio-Synergy, the team is advancing AI and machine learning techniques in epigenetics to improve awareness and lifestyle choices related to health and performance. In the big data security arena, they are partnering with Silo.Network Inc. to pioneer new data processing architectures for predictive analytics software.
In the fields of space exploration and aerospace engineering, they have teamed up with TrustLine Consortium to create dynamic deployment mechanisms for 5G and beyond, addressing the connectivity challenges of massive-scale hybrid-cloud systems. Additionally, their collaboration with Space Health Research is focused on pursuing human spaceflight analog studies aimed at developing effective risk mitigation strategies for human space exploration.
Virtual Reality and AI
Neumann Nexus continues to explore human-AI interaction through VR. It uses it to train AI models on human cognitive patterns, refine adaptive automation, and enhance trust in human-machine collaboration. Katherine explains that VR is particularly useful for AI-driven behavioral modeling, allowing them to study how humans react, learn, and adapt when interfacing with intelligent systems – from next-generation cockpit designs to AI-augmented decision support systems. She points out that as AI systems continue to evolve, VR remains a powerful bridge between digital intelligence and human intuition, shaping the way one designs AI to be more human-aware and adaptive to one’s cognitive processes.
A CEO’s Primary Responsibilities and Approach
As CEO, Katherine’s primary responsibility is to shape the vision and direction of Neumann Nexus. She explains that this involves setting strategic priorities, building new partnerships, and fostering a culture of innovation and ethical leadership. She also ensures that their work consistently reflects their mission, which is to align technology with human potential.
Every day, Katherine spends a significant amount of her time collaborating with their team on key projects and engaging with clients to understand their unique needs and challenges. She also explores emerging trends in AI and cognitive engineering. “I also take great care to nurture our company culture,” Katherine says, “as I believe that an inspired, empowered team is the foundation of any successful organization.”
Katherine’s work schedule is demanding. Is she able to maintain a balance between her personal and professional life? She says, “work-life balance has been a lifelong challenge for me.” She has had to learn to embrace work-life integration.
She recalls her graduate school days when she used to work three research jobs, six days a week; she went nearly five years without taking a vacation. That period taught her the dangers of burnout and the importance of boundaries. “I promised myself that I wouldn’t let my ambition overshadow my well-being again,” Katherine says. She now believes in setting clear priorities and boundaries. For instance, she focuses on results rather than rigid schedules, giving herself and her team the freedom to work in ways that align with their natural productivity cycles. She also trusts her team to take ownership of their work. This allows Katherine to focus on high-impact decisions without micromanaging.
As CEO, she has built flexibility and balance into the very fabric of the company culture. She believes in prioritizing what matters most — whether that’s carving out time for family, pursuing a creative hobby, or simply stepping away to recharge. “Finally, I schedule time for personal growth and reflection, which keeps me grounded and prevents the industry’s pace from overwhelming me,” Katherine says.
Harmonious Evolution of Artificial and Human Intelligence
Katherine sees Neumann Nexus as an architectural force in sculpting the future relationship between humans and AI. She points out, “We’re not merely developing technology; we’re establishing fundamental principles for how artificial and human intelligence can harmoniously co-evolve.”
“Imagine a future where AI systems are as attuned to human cognitive patterns as a master violinist is to their instrument—where technology amplifies our inherent capabilities rather than replacing them.
“But perhaps our most profound impact will be leaning towards philosophical,” Katherine says. They are challenging the prevailing narrative that AI is a competitor to human intelligence. “Our team is working to demonstrate how technology can serve as a cognitive scaffold for human achievement. Think of how the invention of writing amplified human memory and knowledge transmission: we’re working toward AI systems that could similarly extend human cognitive capabilities in ways we’re only beginning to imagine,” Katherine says.
For future generations, she envisions Neumann Nexus’s legacy extending beyond technological innovation. According to her, they are establishing a new ethical framework for human-AI interaction, one that places human flourishing at its core. “My hope is that decades from now, people will look back and recognize Neumann Nexus as a crucial inflection point, where we chose to develop AI not as a replacement for human capability, but as a catalyst for expanding the boundaries of human achievement,” says Katherine.
Message to Aspiring Leaders
Katherine advises aspiring leaders in AI to cultivate both technical expertise and a deep understanding of human needs and values. “Leadership in this field requires more than technological prowess,” she points out. “It demands empathy, ethical reasoning, and a willingness to take responsibility for the societal impact of your work.”
She also encourages future leaders to embrace collaboration, as, according to her, challenges in AI are too complex for any one person or discipline to solve alone. “Finally, be bold in your vision but grounded in your principles,” Katherine adds. “The most transformative leaders of our future will be those who innovate with purpose and integrity.”
