The study, led by Zhongchi Li, a graduate student in psychology at the University of Florida, and co-authored by Gregory Webster, professor of psychology at the university, set out to answer a question that has become increasingly urgent in an era of rising living costs and economic uncertainty. Economic issues are increasingly important nowadays, Li explained, and the researchers wanted to understand how couples handle economic stress, how that stress can influence relationship stress, and what couples can do about it. The team’s approach was deliberately granular: rather than asking people to recall their stress levels in broad strokes, they tracked them in near real time.

Eighty-four unmarried couples participated in the study. Each member of each couple completed a baseline survey measuring their overall levels of financial stress and relationship stress. Then, for seven consecutive days, every participant reported their stress once a day. This daily diary design is a well-established method in relationship science because it captures the natural rhythm of stress as it rises and falls across ordinary life. Instead of relying on memories that may be distorted by a particularly good or bad week, researchers can observe how a stressful event on one day is associated with tension between partners on the same day or shortly afterward.

The results confirmed a pattern that relationship researchers call spillover. Couples who reported greater financial stress at the beginning of the study also reported more stress in their relationships. In other words, the pressure of money problems does not remain confined to the domain of finances; it bleeds into how partners interact, communicate, and feel about each other. A second process, known in the literature as crossover, can also occur, in which one partner’s stress is transmitted to the other, so that the strain experienced by one person becomes a shared burden within the couple.

What made the new study distinctive was its focus on what couples actually do to cope. The daily surveys asked participants about two distinct support mechanisms. The first was emotional support: listening, showing understanding, expressing care, and validating a partner’s feelings. The second was problem solving: offering concrete solutions, advice, or practical steps to address the financial problem itself. Both are common responses, and both are usually well intentioned. When a partner worries aloud about a bill, the instinctive reaction is often to propose a fix, whether that means suggesting a budget change, a second job, or a way to cut expenses.

During the week-long survey period, one of these mechanisms proved clearly more effective. Partners who received more emotional support showed a reduced spillover of financial stress onto the relationship, while simply offering solutions did not produce the same protective effect. For financial stress, Li said, the most important thing is for partners to show more emotional understanding, show care, and be supportive of each other, rather than simply giving solutions to the problem. The finding suggests that when money is the source of anxiety, what a stressed partner often needs first is to feel heard and understood, not to be handed a plan of action.

There are several plausible reasons why emotional support may outperform problem solving in this context. Financial problems are frequently chronic and cannot be resolved in a single conversation; rent recurs every month and debt can take years to pay down. Offering solutions to a problem that cannot be quickly fixed may inadvertently signal impatience or minimize the partner’s distress. Emotional support, by contrast, addresses the immediate psychological need, reducing the arousal and negative affect that would otherwise be carried into interactions with the partner. In effect, feeling understood may interrupt the chain that links financial worry to relational conflict, even while the underlying financial problem remains unresolved.

The findings carry practical weight for couples navigating economic pressure, particularly those living paycheck to paycheck. Webster noted that for such couples, a relationship can serve as a buffer against financial stress, or it can compound that stress, depending in part on how partners communicate. The same household facing identical financial circumstances may experience very different relational outcomes based on whether partners respond to each other’s anxiety with empathy and validation or with immediate, unsolicited fixes. This reframes emotional support not as a soft or secondary skill but as a concrete mechanism that protects relationship quality under strain.

The study also has limitations that the researchers themselves acknowledge. The daily diary covered only seven days, a snapshot that cannot reveal how support dynamics play out over months or years. Webster said future research could follow couples over longer periods, tracking stress around paychecks, rent, and other recurring financial obligations to see how relationships are affected in the long term. Longer studies could also test whether the benefits of emotional support accumulate, whether couples can learn to provide it more consistently, and whether problem solving becomes more valuable once emotional needs have been addressed.

For now, the research offers a clear, evidence-based takeaway for couples under financial pressure: the most helpful response to a partner’s money worries may not be advice at all. Acknowledging the difficulty, expressing care, and demonstrating understanding appear to act as a psychological shock absorber, preventing economic anxiety from converting into relational conflict. As economic pressures continue to shape household life, the study suggests that one of the most valuable resources a couple possesses is not financial at all. It is the capacity of each partner to make the other feel understood when the bills come due.

The award, which will span three years, is designed to support innovative, high-risk, high-reward research programs led by early-stage investigators. In Kim’s case, it funds an ambitious cross-disciplinary effort to translate technology built in the quantum laboratory into a practical biomedical instrument. It marks the first time her quantum-sensor technology will be applied to biomedical research, with endometriosis serving as the inaugural clinical application, supported by an interdisciplinary team that spans engineering and medicine across the university.

The physics at the heart of the project rests on one of nature’s most convenient accidents. Certain defects in the diamond crystal lattice — most notably the nitrogen-vacancy center, in which two adjacent carbon atoms are replaced by a nitrogen atom and a missing atom — behave as tiny quantum systems whose electronic spin states can be initialized, manipulated and read out optically, even at room temperature. These spin states are exquisitely sensitive to magnetic fields, allowing the diamond to function as a nanoscale magnetometer. Unlike conventional quantum sensors that demand cryogenic cooling or vacuum systems, diamond-based platforms can operate under ordinary laboratory and potentially clinical conditions, which is precisely what makes them attractive for probing living tissue. Kim’s team has already developed such a quantum sensing platform — a diamond chip — in her laboratory, and the Trailblazer Award will fund the engineering work needed to point that extraordinary sensitivity at biological problems.

Why magnetic signals? Biological tissues generate weak magnetic fields as a by-product of their electrical and metabolic activity. These fields are fantastically faint — far too weak for conventional magnetometers to pick up reliably at the microscopic scale — but quantum sensors built on diamond can, in principle, resolve them. The hypothesis driving Kim’s project is that endometriotic tissue carries measurable magnetic and metabolic signatures that distinguish it from healthy tissue, and that a sufficiently sensitive, minimally invasive probe could read those signatures directly. If successful, the approach would allow clinicians to detect the disease quantitatively, at an earlier stage, without the invasive procedures that current diagnosis demands.

That diagnostic gap is the clinical engine behind the project. Today, endometriosis is typically confirmed only through laparoscopic surgery, requiring hospitalization, general anesthesia and a surgeon’s trained eye to locate lesions that can be small, scattered and visually ambiguous. Patients routinely wait years from the onset of symptoms to a definitive diagnosis, during which time the disease — a debilitating inflammatory condition — can progress, causing chronic pain, scarring and infertility. “Endometriosis is a debilitating inflammatory disease that affects one in 10 women and currently lacks reliable noninvasive diagnostic tools,” Kim said. “Our goal is to engineer quantum sensors that can measure biological signatures that have previously been extremely difficult to access. By bringing that capability to endometriosis, we hope to enable earlier and more quantitative detection while establishing a broadly applicable platform for magnetic and metabolic diagnostics in women’s health.”

The technical challenge Kim has set for herself is substantial: taking the extraordinary sensitivity demonstrated by quantum systems in the laboratory and packaging it into a practical tool capable of measuring real biological tissue. Quantum sensors are notoriously delicate instruments, and bridging the gap between a carefully controlled optical bench experiment and a clinic-ready measurement of human tissue requires solving problems in sensor design, signal extraction, sample handling and data interpretation all at once. That is why the project is, from its inception, a team effort rather than a solo engineering exercise. “As engineers, we develop powerful technologies, but we need to understand the problems that matter to the people who will ultimately use them,” Kim said. “That is what makes this collaboration so exciting. We are bringing together quantum sensing, biomedical engineering and clinical expertise to solve a problem none of us could address alone.”

Kim’s collaborators bring exactly the complementary expertise the project demands. Jon Dobson, the J. Crayton Pruitt Family Emeritus Professor of Biomedical Engineering, contributes deep experience in applying physical-science techniques to biomedical questions, including magnetically based diagnostic and therapeutic approaches. Amira Quevedo, an assistant professor in the Department of Obstetrics and Gynecology at the UF College of Medicine, serves as the project’s primary clinical researcher. “Investigators with different backgrounds often bring unique perspectives to bear on a problem, especially when it is outside their specific area of expertise,” Dobson said. “This project would not have been possible without combining Dr. Kim’s exceptionally innovative technology with Dr. Quevedo’s passion for helping her patients and knowledge of endometriosis.”

Quevedo’s role anchors the effort in clinical reality. She will determine the best approach for evaluating and integrating Kim’s technology using tissue from participants with endometriosis, and she will facilitate patient recruitment through the UF Health Center of Excellence in Complex Endometriosis Care. That clinical pipeline is essential: validating a fundamentally new sensing modality requires carefully characterized tissue samples and clinicians who understand both the disease’s biology and the everyday constraints of gynecologic practice. “Dr. Kim’s innovative technology has the potential to fundamentally change how endometriosis is diagnosed, shifting us from a predominantly hospital-based diagnosis that requires abdominal surgery and general anesthesia toward a simplified, clinic-based approach that could ultimately be incorporated into an outpatient gynecologic visit,” Quevedo said. For patients, that shift could be transformative — replacing a major surgical confirmation with something closer to a routine examination.

Quevedo, who works alongside Kim, Dobson and the team’s students, describes the collaboration as a chance to see the disease through an entirely new lens. “Bringing together our strengths as collaborators allows us to ask questions and develop solutions that would not otherwise be possible,” she said. “Patients constantly ask me why their endometriosis was not detected sooner. Earlier diagnosis creates an opportunity for earlier access to effective therapies, less cumulative disease burden and ultimately better quality of life for people living with endometriosis.”

If the three-year program succeeds, its implications may extend well beyond a single disease. Kim describes the platform as broadly applicable to magnetic and metabolic diagnostics in women’s health, suggesting that a validated diamond-based quantum sensor could one day serve as a general-purpose instrument for reading the faint magnetic fingerprints of biological tissue — whether to detect inflammation, monitor metabolism or screen for other conditions that currently evade early diagnosis. For a field in which quantum technology has often promised more than it has delivered to medicine, the project represents a carefully targeted attempt to move a quantum sensor out of the laboratory and into the clinic, one of the most consequential journeys an emerging technology can make. It begins, fittingly, with a disease that medicine has struggled to see for far too long — and with a diamond chip built to make the invisible measurable.
