Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”

New energy innovation and coworking spaces open at the Ion

moving in

Houston-based Occidental officially opened its new Oxy Innovation Center with a ribbon cutting at the Ion last week.

The opening reflects Oxy and the Ion's "shared commitment to advancing technology and accelerating a lower-carbon future," according to an announcement from the Ion.

Oxy, which was named a corporate partner of the Ion in 2023, now has nearly 6,500 square feet on the fourth floor of the Ion. Rice University and the Rice Real Estate Company announced the lease of the additional space last year, along with agreements with Fathom Fund and Activate.

At the time, the leases brought the Ion's occupancy up to 90 percent.

Additionally, New York-based Industrious plans to launch its coworking space at the Ion on May 8. The company was tapped as the new operator of the Ion’s 86,000-square-foot coworking space in Midtown in January.

Dallas-based Common Desk previously operated the space, which was expanded by 50 percent in 2023 to 86,000 square feet.

CBRE agreed to acquire Industrious in a deal valued at $400 million earlier this year. Industrious also operates another local coworking space is at 1301 McKinney St.

Industrious will host a launch party celebrating the new location Thursday, May 8. Find more information here.

Ion Houston expands tech workforce development partnership with nonprofit

tech training

Houstonians can now apply to a new, tuition-free program at the Ion to boost their tech skills and knowledge.

Earlier this year the Ion announced New York-based Per Scholas as its workforce development partner. And starting October, Per Scholas will launch its 12- to 15- week technology skills training courses at the innovation hub, the Ion announced this week.

The new operation, known as Per Scholas Houston, is backed by support from from BlackRock Inc. and Comcast NBCUniversal.

Per Scholas Houston will first introduce the nonprofit's IT Support course. The program will give students an opportunity to earn a Google IT Support Professional Certificate and the CompTIA A+ certification. Click here to apply.

“Per Scholas commends the vision and commitment of the City of Houston, Ion, Rice University, and so many others, to catalyze change, grow ideas and innovation, and drive impact. We are thrilled that Per Scholas Houston is now part of the effort,” Plinio Ayala, president and CEO of Per Scholas, says in a statement. “With tremendous investment from Ion, BlackRock, Comcast, our proven skills training will develop technologists to power Houston’s workforce today – and tomorrow–creating a more inclusive and equitable economy. We can’t wait to get started.”

According to the company, more than 80 percent of those who complete Per Scholas training programs find full-time employment within a year of graduating, and about 85 percent of Per Scholas graduates are people of color. Per Scholas has 20 locations in the U.S., including a location in downtown Dallas.

Applicants must be 18 or older to apply and have earned a high school diploma or equivalent and be a U.S. citizen or authorized to work in the U.S., according to Per Scholas's website. They must pass an assessments review before beginning coursework, meet the nonprofit's learner pre-training income criteria and be available to attend classes Monday through Friday from 9 a.m. to 4 p.m.

In early May, The Ion announced 10 new tenants that were either relocating or expanding their presence in Houston, bringing the total space leased to 86 percent. Later that month, it added corporate giants Occidental, United Airlines Ventures and Woodside Energy as partners.

Oxy taps Houston startup's carbon negative biotechnology for new pilot plant

sustainability moves

Occidental's venture arm — Oxy Low Carbon Ventures — has announced its plans to construct and operate a one metric ton per month bio-ethylene pilot plant featuring Houston-based Cemvita Factory's technology that biomimics photosynthesis to convert carbon dioxide into feedstocks.

The new plant will scale the process, which was jointly developed between Cemvita and OLCV, and is expected sometime next year, according to a press release from Oxy.

"Today bio-ethylene is made from bio-ethanol, which is made from sugarcane, which in turn was created by photosynthesizing CO2. Our bio-synthetic process simply requires CO2, water and light to produce bio-ethylene, and that's why it saves a lot of cost and carbon emissions," says Moji Karimi, co-founder and CEO of Cemvita Factory, in the release. "This project is a great example of how Cemvita is applying industrial-strength synthetic biology to help our clients lower their carbon footprint while creating new revenue streams."

Oxy and Cemvita have been working together for a while, and in 2019, OLCV invested an undisclosed amount into the startup. The investment, according to the release, was made to jointly explore how these advances in synthetic biology can be used for sustainability efforts in the bio-manufacturing of OxyChem's products.

"This technology could provide an opportunity to offer a new, non-hydrocarbon-sourced ethylene product to the market, reducing carbon emissions, and in the future benefit our affiliate, OxyChem, which is a large producer and consumer of ethylene in its chlorovinyls business," says Robert Zeller, vice president of technology at OLCV, in a news release.

Moji Karimi founded the company with his sister and Cemvita CTO, Tara, in 2017. The idea was to biomimic photosynthesis to take CO2 and turn it into something else. The first iteration of the technology turned CO2 into sugar — the classic photosynthesis process. Karimi says the idea was to create this process for space, so that astronauts can turn the CO2 they breathe out into a calorie source.

"Nature provided the inspiration," noted Dr. Tara Karimi, co-founder and CTO of Cemvita Factory. "We took a gene from a banana and genetically engineered it into our CO2-utilizing host microorganism. We are now significantly increasing its productivity with the goal to achieve commercial metrics that we have defined alongside OLCV."

A couple weeks ago, Moji Karimi joined the Houston Innovators Podcast to discuss growth and challenges Cemvita Factory faced.

"We're defining this new category for application of synthetic biology in heavy industries for decarbonization," he shares on the show. Stream the episode below.

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
