As Houston continues to invest in resiliency for our growing city, a well-equipped workforce is needed to meet the demand for critical infrastructure. It is also important that in a city as diverse as Houston, the engineering and construction talent that encompasses our workforce is reflective of the city itself, aligning with our ever-changing demographics.

While women continue to make strides in the STEM field, according to Pew Research Center, women's shares in the field of engineering have inched up only slightly, from 12% in 1990 to 15% today. And while women now earn a majority of all undergraduate and advanced degrees, they remain a small share of degree earners in fields like engineering and computer science — areas where they are significantly underrepresented in the workforce.

Diversity yields creativity, and women bring a valuable and unique perspective to problem solving and innovation. I grew up in Jamaica and then immigrated to the United States. It wasn't until I was recognized by my high school teacher, Mrs. Owens, for my natural ability to excel in subjects like science and math that I fell in love with the basis of engineering. Without the mentorship and investment of teachers and professionals throughout my career, I would not be where I am today.

In Houston, it is not a question of talent — we have plenty of diverse talent, and many young women entering the engineering workforce. The issue we run into is keeping them here and elevating them to reach the pinnacle of their discipline.

If we want to inspire young women to join the field, and ensure more women remain in it, we need to invest in mentor relationships and create space and opportunities for successful women to grow into positions of leadership.

Invest

Many would agree that mentorship plays a key role in career growth and development, but we need to be specific about what that means and how to do it effectively. For a mentor relationship to be impactful, it needs to be continuous and personal. When girls are in grade school, they are impressionable and open to inspiration. We have the opportunity to help them build confidence and make a difference in their futures.

It is important to remember that women will need several mentors throughout their lives. Obtaining an engineering degree is not easy, and upon graduation, young professionals come to the realization that what was taught in school can be different from what a job requires. New mentors are needed throughout the many seasons of personal and professional growth, and it is the responsibility of successful women engineers to take the time to develop true, lasting relationships with the next generation. We need more individuals who are willing to reach out to young women at a relatable level and establish that personal touch.

Inspire

Once we have women committed to a career in engineering, how do we foster them to go further in the field? We need more females in leadership roles. The high school teacher I mentioned was female and African American. Being able to relate to her eliminated barriers for me. I told myself that if she can do this, and she believes in me and looks like me, then I can do this, too. Young women and professionals need to be able to look at a company or professional organization's board members and executives and see faces that look like their own.

Listen

Last year, over 20 million Americans were out of work due to COVID-19, yet as the pandemic eases, millions of women have yet to return to the workplace. While this may be due to a complex mix of factors, I am left wondering if business leaders are actually asking women why they haven't returned. Many companies make assumptions regarding women's priorities, needs and expectations, without having a conversation. We are left with a shortage in our workforce, which will impact Houston sooner than most cities, and there needs to be an open dialogue between businesses and women to discover what they need to be successful.

Lastly, as women, it is our responsibility to use our voice. If I were to have let the assumptions of others guide my life and career path, I would not be where I am today. If you can persist and you are resilient, you will succeed. Women are here, but let's work together to ensure they are here to stay.

Houston named a top city for women in STEM fields

who runs the world?

If you're a woman in science, technology, engineering, or mathematics and you call Houston home, according to a new report, you're doing it right.

In honor of Women's History Month, CommercialCafe updated its 2020 ranking of the top U.S. cities for women working in STEM. According to the report, Houston ranks at No. 5 on the list of the best southern cities in the United States for women in STEM. The Bayou City also claims the No. 19 spot nationally.

Here are some other key findings about Houston on the report:

  • STEM jobs in Houston account for 7 percent of all jobs, and a little less than a third of these positions are held by women.
  • About 23,964 women work in STEM in Houston — which is the most out of any other city in the South.
  • Houston gained 4,318 new women STEM employees since 2015, the third-highest number in this regional ranking.
  • The median annual income for women in STEM here is $68,172.
Texas makes up about half of the top 10 Southern states — Austin places in second, while Frisco (No. 7), Dallas (No. 8) and Plano (No. 10) fall behind Houston. Nationally, New York City, San Francisco, and Seattle take the top three spots, respectively.

Houston has been recognized for its STEM fields before, and last fall, SmartAsset ranked Houston as No. 7 in STEM nationally based on workforce size. And, in 2019, Houston placed sixth for STEM workforce diversity. Last year Houston also ranked No. 6 for women in tech, also according to SmartAsset.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
