“We are at this inflection point where marketing is changing,” May says in a press release. “We know that the next generation can clearly see that and I think a lot of marketing agencies are starting to catch on. We need to be prioritizing the next generation’s opinion because they are driving who is interested in what they buy. This upcoming generation does not want to be sold to and they don’t like inorganic, inauthentic advertisements. That’s why user generated content is so big, it feels authentic.” Continue reading.

CPRIT CEO: Houston’s $2B in funding is transforming cancer research and prevention

fighting cancer

With its plethora of prestigious health care organizations like the University of Texas MD Anderson Cancer Center, UTHealth Houston, and the Baylor College of Medicine, Houston sits at the heart of cancer research and prevention in Texas.

Of course, it takes piles of cash to support Houston’s status as the state’s hub for cancer research and prevention. Much of that money comes from the Cancer Prevention and Research Institute of Texas (CPRIT).

Data supplied by CPRIT shows organizations in Harris County gained $2.3 billion in institute funding from 2009 through 2025, or nearly $145 million per year. That represents almost 60 percent of the roughly $4 billion that CPRIT has granted to Texas institutions over a 16-year period.

“The life sciences ecosystem that has developed and changed in Houston is phenomenal,” Kristen Doyle, who became the agency’s CEO in July 2024, tells InnovationMap. “In the next decade, we will look back and see a great transformation.”

That ecosystem includes more than 1,100 life sciences and biotech companies, according to the Greater Houston Partnership.

Houston plays critical role in clinical trials

Texas voters approved the creation of CPRIT in 2007. Twelve years later, voters agreed to earmark an extra $3 billion for CPRIT, bringing the state agency’s total investment in cancer research and prevention to $6 billion.

To date, CPRIT money has gone toward recruiting 344 cancer researchers to Texas (mainly to Houston) and has supported cancer prevention services for millions of Texans in the state’s 254 counties. CPRIT funding has also helped establish, expand, or relocate 25 cancer-focused companies. In Houston, MD Anderson ranks as the No. 1 recipient of CPRIT funding.

Regarding cancer research, Doyle says Houston plays a critical role in clinical trials.

“[Clinical trials are] something that CPRIT has focused on more and more. Brilliant discoveries are crucial to this whole equation of solving the cancer problem,” Doyle says. “But if those brilliant ideas stay in the labs, then we’ve all failed.”

Researchers conduct more clinical trials in Houston than anywhere else in the U.S., the Greater Houston Partnership says.

Doyle, a 20-year survivor of leukemia, notes that a minority of eligible patients participate in clinical trials for cancer treatments, “and that’s one of the reasons that it takes so long to get a promising drug to market.”

An estimated 7 percent of cancer patients sign up for clinical trials, according to a study published in 2024 in the Journal of Clinical Oncology.

MD Anderson takes on cancer prevention

Doyle also notes that Houston is leading the charge in cancer prevention.

“We get some national recognition for programs that have been developed in Houston that then can be replicated in other parts of the country,” she says.

Much of the work in Houston focusing on cancer prevention takes place at MD Anderson. The hospital reports that it has received more than $725 million from the CPRIT since 2007, representing approximately 18 percent of CPRIT’s total awards.

“These efforts can have profound impact on the lives of patients and their families, and this funding ensures our exemplary clinicians and scientists can continue working together to drive breakthroughs that advance our mission to end cancer,” Dr. Giulio Draetta, chief scientific officer at MD Anderson, said in a November news release, following the most recent CPRIT award for the hospital totaling more than $29 million.

CPRIT funding for Houston institutions supplements the more than $4.5 billion in federal funding for health and life sciences research and innovations that the Houston area received from 2020 to 2024, according to the Greater Houston Partnership.

“We are curing cancer every single day,” Doyle says of CPRIT. “Every step that we are taking — whether that’s funding great ideas or funding the clinical trials that are bringing promising drugs to Texas and to the world — we are making a difference.”

Houston energy tech co. breaks ground on low-cost hydrogen pilot plant

Coming Soon

Houston’s Lummus Technology and Advanced Ionics have broken ground on their hydrogen pilot plant at Lummus’ R&D facility in Pasadena, Texas.

The plant will support Advanced Ionics’ cutting-edge electrolyzer technology, which aims to deliver high-efficiency hydrogen production with reduced energy requirements.

“By demonstrating Advanced Ionics’ technology at our state-of-the-art R&D facility, we are leveraging the expertise of our scientists and R&D team, plus our proven track record of developing breakthrough technologies,” Leon de Bruyn, president and CEO of Lummus, said in a news release. “This will help us accelerate commercialization of the technology and deliver scalable, cost-effective and sustainable green hydrogen solutions to our customers.”

Advanced Ionics is a Milwaukee-based low-cost green hydrogen technology provider. Its electrolyzer converts process and waste heat into green hydrogen for less than a dollar per kilogram, according to the company. The platform's users include industrial hydrogen producers looking to optimize sustainability at an affordable cost.

Lummus, a global energy technology company, will operate the Advanced Ionics electrolyzer and manage the balance of plant systems.

In 2024, Lummus and Advanced Ionics established their partnership to help advance the production of cost-effective and sustainable hydrogen technology. Lummus Venture Capital also invested an undisclosed amount into Advanced Ionics at the time.

“Our collaboration with Lummus demonstrates the power of partnerships in driving the energy transition forward,” Ignacio Bincaz, CEO of Advanced Ionics, added in the news release. “Lummus serves as a launchpad for technologies like ours, enabling us to validate performance and integration under real-world conditions. This milestone proves that green hydrogen can be practical and economically viable, and it marks another key step toward commercial deployment.”
