Rice University's edtech company receives $90M to lead NSF research hub

major collaboration

An educational technology company based out of Rice University has received $90 million to create and lead a research and development hub for inclusive learning and education research. It's the largest research award in the history of the university.

OpenStax received the grant funding from the U.S. National Science Foundation for a five-year project create the R&D hub called SafeInsights, which "will enable extensive, long-term research on the predictors of effective learning while protecting student privacy," reads a news release from Rice. It's the NSF's largest single investment commitment to national sale education R&D infrastructure.

“We are thrilled to announce an investment of $90 million in SafeInsights, marking a significant step forward in our commitment to advancing scientific research in STEM education,” NSF Director Sethuraman Panchanathan says in the release. “There is an urgent need for research-informed strategies capable of transforming educational systems, empowering our nation’s workforce and propelling discoveries in the science of learning.

"By investing in cutting-edge infrastructure and fostering collaboration among researchers and educators, we are paving the way for transformative discoveries and equitable opportunities for learners across the nation.”

SafeInsights is funded through NSF’s Mid-scale Research Infrastructure-2 (Mid-scale RI-2) program and will act as a central hub for 80 partners and collaborating institutions.

“SafeInsights represents a pivotal moment for Rice University and a testament to our nation’s commitment to educational research,” Rice President Reginald DesRoches adds. “It will accelerate student learning through studies that result in more innovative, evidence-based tools and practices.”

Growing Houston tech nonprofit expands access to textbooks for college students

openstax updates

If everyone that attended a college or university were polled, they’d all likely agree that one of the worst parts of the experience was the rising costs of textbooks.

In an effort to combat the hefty price tag of assigned texts, OpenStax, a nonprofit education startup out of Rice University, which is on a mission to increase educational access for all, seeks to democratize high-quality education by offering free, peer-reviewed, openly licensed textbooks for students and knowledge seekers across the globe.

This month, OpenStax will add to its 57 open education resources, or OER, titles with a full version of John McMurry's popular pre-med textbook, Organic Chemistry, under an open license to honor his late son, Peter, who passed away in 2019 after losing his battle with cystic fibrosis.

“The author, John McMurry, granted us the ability to publish the 10th edition openly,” Anthony Palmiotto, director of higher education at OpenStax, tells InnovationMap. “So, the most widely used organic chemistry textbook went from being one of the most expensive undergraduate texts on the market (almost $100), to a free and open text, making this a watershed moment for OER.”

This school year, OpenStax is adding 16 academic institutions onto its platform, including Georgia State University, Southwest Texas Junior College, Texas A&M University-Commerce, University of San Diego, and more. It's the largest batch of new schools OpenStax has onboarded in a year, Palmiotto says in a news release.

Founded to increase access

OpenStax founder and director Richard Baraniuk, a professor of Electrical and Computer Engineering at Rice University, started the OER publisher in 1999 to remove financial barriers and make educational resources more widely available. Much like increasing access to McMurry’s Organic Chemistry, the goal is to continue to support both learners and educators by providing easily accessible and well-developed materials.

“Our mission is to support all learners in their educational pursuits by providing access to high-quality education,” Palmiotto says. “Richard Baraniuk founded it initially as a way for faculty and others to get their material and their knowledge in the form of textbooks and other learning materials to students.

“And then born out of that, we started this robust textbook development and course material development program where we put out the highest-quality materials we can in a way that fits the way courses are taught. Meaning convenience and scope and sequence and other needs that instructors must use textbooks. So really the access was really the start of it, increasing that and lowering barriers to education, and then a lot flowed from that.”

OpenStax’s library of OER titles, which are published under a Creative Commons Attribution license, are free and easily accessible on the go and usable on any device in multiple formats, including digital and PDF.

Funded by philanthropic supporters, OpenStax normally works to openly access five or six books per year, working mostly on introductory courses. Most recently, the Texas Higher Education Coordinating Board funded the publisher to do a series of nursing books, eight in total.

“Before the nursing books, we were doing business books,” Palmiotto says. “Murry’s book builds out our science offerings, so we're thinking about the different areas that students take that can be barriers for them to move up in education and succeed. From there, we’ll continue to think about how a free textbook can help students through that process.”

Tapping into tech

In addition to nursing, OpenStax is working towards releasing books in data science and computer science, including programming, workplace software and, eventually, artificial intelligence.

“AI is a big deal to us,” says Palmiotto. “We're thinking about it a lot, and in the books themselves, we're incorporating as best we can how AI plays into Data Science, Computer Science and Python Programming those. We’re thinking about how AI could be used and will impact programming, for example. But the AI landscape is changing as we go, and that's another reason we don't just put out the books, we maintain them.

“So, we can continually update them. Once we publish, six months later, we can publish updates or additions to reflect what's happening in courses or in professions or in the workforce to reflect how AI is being used as new software is released and so on.”

As OpenStax continues to build on its OER title database, they are using multiple methods of outreach to reach as many people as possible. Currently, they have over 7.5 million users in the formal education space, primarily in higher education introductory courses, as well as grades K–12.

“Over 140 countries are using our material,” says Palmiotto. “We're not as easily able to track how many students have used our material in all those other countries. But that's not the point, we want to put it out there. We know it's being used. We want to help as much as possible. But it is being used in all those countries and in different ways. Some people are translating it. Some people are using it in English. Some people are breaking it up. It just depends on what they need.”

Evolving the industry

As much as OpenStax is a disrupter to conventional textbook publishers, they would rather work in partnership with publishers like Murry’s former house Cengage rather than outright replacing them.

“What we've tried to do with those publishers is actually partner with them and say, we know that textbook prices were too high,” says Palmiotto. “Some of them partnered with us, Cengage, Riley, some of the other publishers, like Macmillan, incorporate our textbooks into their platforms so that instructors and students have that flexibility even with those publishers.

“Not every publisher wants to do that. That's their choice. But what we've tried to do is say ‘let's make an ecosystem.’ That's what we call it and let them participate in this movement that open education has become.”

With their textbooks on an open forum, it might seem that OpenStax texts would be susceptible to hacking or other unauthorized changes. But, according to Palmiotto, there’s a safeguard to that.

“We keep the standard version,” he says. “That's why a lot of people keep using it because they know that the version that we provide will be the most up-to-date version. But it is openly licensed. So, if we see that a school wants to teach the course in a slightly different way or if they want to recombine two different books to make a different course, take biology and make human biology, or take philosophy and make ethics or something, they can do that.

“But we still retain the standardized version that we redistribute and make sure that that's the high-quality one that people can look to. So nobody is getting back to our version and changing it, but they do have the opportunity to change their own.”

After more than a decade in the space, OpenStax repeatedly receives feedback from users worldwide that appreciate the openness and availability of their books.

“We have some great stories of different learners from all over the world that are non-traditional students facing barriers,” says Palmiotto. “And having a free textbook and not having to choose between food and their book or courseware makes a huge difference in their lives. If they have this flexibility in what they have to purchase, most people appreciate that choice.”

5 Houston researches named to prestigious engineering organization

newly named members

A national organization has named its latest cohort of new members — which includes Elon Musk — and five Houston-area innovators have also made the cut.

The National Academy of Engineering elected 111 new members and 22 international members, bringing the total U.S. membership to 2,388 and the number of international members to 310. The appointment is among the highest professional distinctions in an engineer's career. Each member has been found to have made significant contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature," according to a news release.

The newly elected class will be formally inducted during the NAE's annual meeting on Oct. 2. The five Houston-area appointees and what they are being recognized for are:

  • Richard G. Baraniuk, C. Sidney Burrus Professor, Department of Electrical and Computer Engineering, Rice University. For the development and broad dissemination of open educational resources and for foundational contributions to compressive sensing.
  • Donald Nathan Meehan, president, CMG Petroleum Consulting Ltd.. For technical and business innovation in the application of horizontal well technology for oil and gas production.
  • Pradeep Sharma, M.D. Anderson Chair Professor and department chair, Department of Mechanical Engineering, University of Houston. For establishing the field of flexoelectricity, leading to the creation of novel materials and devices and insights in biophysical phenomena.
  • Leon Thomsen, chief scientist, Delta Geophysics Inc. For contributions to seismic anisotropy concepts that produced major advances in subsurface analysis.
  • David West, corporate fellow, Corporate Research and Innovation, Saudi Basic Industries Corp. For solutions to problems with technological, commercial, and societal impacts while advancing chemical sciences by applying reaction engineering fundamentals.

In a news release from UH, Sharma says it's the highest honor he could achieve as an engineer. The NAE recognized Sharma's work within flexoelectricity, a relatively understudied, exotic phenomenon that has the potential to provide similar functionality as piezoelectrics.

“Nature has provided us very few piezoelectric materials even though their applications in energy harvesting and in making sensors is very important. What we did was use theory to design materials that perform like piezoelectric ones, so that they can create electricity,” says Sharma in the release.

Sharma has worked at UH since 2004, and previously conducted research at General Electric for three years.

“The recognition of Professor Sharma by the National Academy of Engineering highlights a career full of outstanding research that has contributed to the understanding of engineering and helped uncover solutions for some of the world’s most significant problems,” says Paula Myrick Short, UH senior vice president for academic affairs and provost, in the release.

Over at Rice, Baraniuk's engineering career includes computational signal processing, most recently as it relates to machine learning. He's best known for spearheading the creation of Connexions, one of the first open-source education initiatives, and its successor, OpenStax, which publishes high-quality, peer-reviewed textbooks that are free to download.

“It’s auspicious timing that the NAE citation mentioned open education, because the seventh of February was the 10th anniversary of OpenStax publishing its first free and open textbook,” he says in a release from Rice. “It’s neat to have this happen in the same week, and worth pointing out that if ever there was a team effort, it was Connexions and OpenStax.”

Baraniuk has been at Rice since 1992, has three degrees in electrical and computer engineering.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
