You've just been named CEO of a Fortune 500 company. Your ego fills the room. The laws of gravity don't apply to you.

And naturally, you want to make an impact. So you pour money into mergers and acquisitions, and when you're not trying to acquire another firm, you guide company resources into research and development. You're a genius, and the world will soon be clinging to your every new product.

The only problem: your company will likely underperform. Research by former Rice Business visiting professor Sean Wang (now at Cox School of Business as SMU), along with Nicholas Seybert of the University of Maryland and Charles Ham of Washington University at St. Louis, reveals the high costs of an out of control CEO ego.

The researchers' first challenge was establishing who could legitimately be called a narcissist. What does the term mean, exactly? While there are varying definitions, Wang's team focused on narcissism as a basic personality trait rather than a mental illness. As a personality trait, narcissism is associated with entitlement, vanity, authority, and a sense of superiority.

To spot narcissists, the team took a novel approach: they examined their research subjects' signatures. Signature size turns out to be a handy measure for egos, because it doesn't require participants to answer direct questions about their personalities — and because participants are unlikely to know that ego can affect something as simple as a signature.

Just having a big ego, though, does not a narcissist make. To validate a link between a person's signature and narcissism, the researchers asked 53 graduate business students to provide their signatures by signing a document, and then to take a personality survey that measured narcissism. The findings documented that indeed there was a strong correlation between signature size and narcissism.

Next, the researchers obtained data from prior psychology research on employee perceptions of 32 technology-firm CEOs. Of the 24 CEOS for whom the researchers also had signature samples, they found a significant correlation between narcissism and signature size.

Armed with these findings, Wang and his colleagues were able to extrapolate the narcissistic traits of thousands of CEOs whose signatures were readily available on proxy statements and other corporate documents. The researchers ultimately studied 741 CEOs from 411 firms during the period between 1992 and 2015, corresponding to 6,361 firm-year observations with a median of eight fiscal years per CEO.

They found a pronounced behavior pattern. Firms led by narcissistic CEOs invested more in high-exposure areas such as research and development and mergers and acquisitions, but shied away from routine capital expenditures for day-to-day productivity. This trend was even more pronounced during periods of financial slack, suggesting that narcissistic CEOs prefer an aggressive management style whenever possible. Financial productivity delivered by these narcissistic CEOs in terms of profitability was lower than their less egotistic counterparts.

The research has multiple implications. Narcissistic leaders, past research shows, are prone to make bad decisions — in part because they are bad listeners. As a result, they often dominate the decision process without incorporating feedback or ideas from others. Ironically, they mistakenly perceive this behavior as a signal of competence and strong leadership.

To counter these bad habits, the researchers say, during periods of financial sluggishness investors and corporate boards should combat excessive narcissist-led investment by pushing for higher dividend payouts. Given that narcissistic CEOs overinvest in R&D, investors also need to closely monitor whether such investments represent real innovation or just vanity. Finally, boards of directors should be aware that narcissistic leaders tend to command higher salaries — and consider whether their CEO falls into this category, and is essentially getting higher pay for inferior performance.

In short, to really be as boss as they see themselves, narcissistic corporate leaders need to recognize their tendencies and rigorously check their egos. Boards, meanwhile, should closely monitor their CEO's priorities in directing firm resources. It could be the writing on the wall.

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
