Cultural connections key to success of ASU's first-generation students

Conference shows strengths, obstacles for first-generation students at ASU.

First-Gen Zone Conference examines path for first-time college-goers

First-generation students start college as trailblazers in their families, and while that can present challenges, it’s also a source of strength.

Nancy Gonzales, dean of natural sciences in The College of Liberal Arts and Sciences at Arizona State University, found her parents’ lack of expectations to be freeing.

“In grad school, in some ways I was protected,” she said.

“Others felt pressure to live up to high expectations from their families, but I felt like I was there because I wanted to be.

“It allowed me to chart my own direction as a scholar.”

Gonzales was a keynote speaker at the 2020 First-Gen Zone virtual conference, held Nov. 5. This was the second conference for faculty and staff to learn ways to support first-generation college-goers, which represent about 35% of ASU’s undergraduate population, according to Kevin Correa, director of the First-Year Success Center.

The total number of undergraduate and graduate first-generation students at ASU is nearly 30,000, Correa said. ASU considers first-generation students to be those who are the first in their family to attend college.

Gonzales, Foundation Professor of psychology, has devoted her career to researching family resilience and has found that sustaining family and cultural connections is vital for students’ perseverance and mental and physical health.

“We need to make sure that when they come to campus, they are able to connect with others like them in culturally meaningful ways, and we need to give them space to do that and give them groups to do that,” she said.

Gonzales said that faculty must be mindful of the burdens on students who are expected to work to help support their families.

“In science, students sign up for labs and it’s often really long hours of work. That’s part of the expectation,” she said.

“We need to make it possible for them to do it on their terms and be flexible about expectations.”

The conference addressed the importance of intersectionality, or the different identities that a first-generation student holds, such as LGBTQ, Native American or DACA. Those different identities are also avenues to finding connection.

Shundene Key, a first-year doctoral student in biochemistry, spoke on a panel of first-generation graduate students and described why she chose ASU.

“I know ASU has resources for me, like American Indian Student Support Services and places to connect like the American Indian Graduate Student Association,” she said.

“I felt like with those two combined, I would have a more positive experience here at ASU.”

Kiana Maria Sears, assistant director of faith-based outreach and community partnerships, talked about the Black and African American first-generation experience. She is an ASU alumna and parent of an ASU student.

“Safe spaces is one of the things that matters most and is one of the most difficult and challenging things to tackle,” she said.

Sears said she is excited for ASU President Michael Crow’s recently released “25 actions to support Black students, faculty and staff,” particularly the plan for service time for Black faculty and staff to mentor students.

“I know what it’s like to be on campus, and, in my generation, go a whole week without seeing someone who looks like you,” she said. “It’s good to not only see that person but also to connect and feel that all these spaces are our spaces.”

In her outreach, Sears has found that financial literacy is a critical issue. Many Black families are middle class, above the poverty line, and don’t have access to the same financial aid information as low-income families.

Nationwide, about 85% of Black bachelor’s degree holders have student debt averaging more than $36,000 – the highest of any race or ethnicity, she said.

Black families are less likely to reach out for help in untangling financial aid because typically there is no one in the institution who looks like them.

“This is basically the student putting on a backpack loaded with bricks,” she said.

The conference covered several programs that target specific populations of first-generation students at ASU, including:

Game Changers: This initiative within the First-Year Success Center has a wide range of digital offerings, including peer coaching, networking on Slack, events and student videos.

TRIO Student Support Services: This is for first-generation students who are either low-income or have a disability, and offers tutoring, community service opportunities, workshops, cultural experiences such as shows at Gammage Auditorium, and a program that loans laptops and cameras.

Engineering Futures: The National Science Foundation and private donations fund this program that provides workshops and seminars to build student confidence. In 2019, students attended a weeklong boot camp to hone their skills and develop an entrepreneurship mentality.

Several of the speakers discussed “imposter syndrome” — when people feel that they don’t belong in a space.

Sears said that for Black and African American students, imposter syndrome can be a “double bind.”

“It’s not just the inside voice but what’s actually being said by people outside,” she said.

Keynote speaker Jaime Casap was until recently the “chief education evangelist for Google” and now works on projects involving equity in higher education. He was a first-generation student.

“Everyone needs to focus on human skills – critical thinking, problem solving, creativity,” he said.

“As a 52-year-old professional ex-Googler, I still feel imposter syndrome. It’s one of those things that exists.

“But these skills will give you a competitive advantage.”

The graduate students on the panel said that meeting the right people made all the difference.

“I didn’t just force myself into these places,” said Esteban Medrano, who is in the last semester of his master’s degree in health care delivery.

“It was because I knew somebody who not only wanted me to succeed but brought the opportunity to connect with others who wanted me to succeed.”

Medrano is in the Deferred Action for Childhood Arrivals program, and had to overcome many obstacles, including being blocked from any federal financial aid.

“Thanks to ASU, you can connect to people who can find resources and opportunities. They all want you to continue pursuing your education.”

Algae engineering: A stepping stone to sustainable solutions

November 6, 2020

Among ways being explored to combine biology and engineering to remedy a range of growing global environmental problems, algae-based solutions look especially promising.

The encouraging viewpoint stems from progress in research that is revealing how the properties of algae can be harnessed to become the driving force for a slew of productive biotechnological pursuits.

Some of the research findings have been the result of efforts based at the Arizona Center for Algae Technology and Innovation, or AzCATI, embedded in the Ira A. Fulton Schools of Engineering at Arizona State University.

Algae is an abundant and widely varied group of aquatic organisms capable of producing oxygen through photosynthesis and thereby harvesting energy from sunlight to grow and produce a range of biochemicals.

That capability and related characteristics can make algae a useful component in the development of advanced systems for effectively treating wastewater, producing cleaner energy and new biofuels, reducing harmful carbon dioxide emissions and improving decontamination and pollution control techniques.

Engineers and scientists say the chemical components in algae can also strengthen materials used to build transportation systems and other public infrastructure — while sequestering carbon in the process to substantially boost the sustainability of both natural and built environments.

An essential testbed site for algae-related industries

AzCATI launched in 2010 with a multimillion-dollar investment from Science Foundation Arizona, a nonprofit with the mission of diversifying Arizona’s economy by aligning university research with the needs of industry.

The foundation’s support financed the development of several acres of algal growth ponds on ASU’s Polytechnic campus — located close to biochemical and molecular biology labs with resources available for use in AzCATI’s projects, particularly the cultivation of algal biomass for biofuels.

Before long, the center became one of the major testbeds for algae biotechnology-derived products, including nutraceuticals, biofuels, food and feed and high-value pharmaceuticals — all from algae biomass. This was possible due in large part to the Department of Energy-funded ATP3 consortium, which is designed to accelerate research and development of algae-based technologies.

“We’ve become basically the algae farmers for many public and private ventures that need to make advances in algae cultivation and productivity to reach their goals and our goals,” said John McGowen, AzCATI’s director of operations and an ASU sustainability scientist. “We collaborate with industry and academics to ‘road-test’ technology, and use data being generated by our testbed site to contribute to reducing technology risk and helping to propel the success of these enterprises.”­­­­­

The center now has longstanding working relationships with major U.S. research facilities, including the National Renewable Energy Laboratory, the Pacific Northwest National Laboratory, Los Alamos National Laboratory and Sandia National Laboratories.

“Most of the national labs don’t have access to their own outdoor testing facilities, so they can come to us,” McGowen said. “Recently, through the DOE-funded DISCOVR consortium, we’ve achieved some of the highest outdoor algae cultivation productivity rates ever.”

Expanding applications of algae research and development

AzCATI’s leaders say many students and others who have worked at the center have gone on to use what they learned from the experience in their careers.

AzCATI is part of ASU’s LightWorks, an accelerator that focuses on advancing solar energy generation and other sources of sustainable energy, fuels and related products. The center is also part of the School of Sustainable Engineering and the Built Environment, one of the six Fulton Schools.

Through its connection to LightWorks and the school, AzCATI has been able to draw on a broad array of engineering and science resources and expertise, helping the center attract close to $70 million from public agencies, industry and foundations — as well as partnering with startups to obtain small business innovation grants — leading to significant expansion of AzCATI’s activities during its first decade.

Over that time, the use of algae in products has notably increased. Algae is now an ingredient in foods (for humans and animals), cosmetics, nutritional supplements like omega-3 oils, antioxidants, coloring agents, dyes for fabric, sunblock lotion, printing ink, flour and paper, among many other consumer products.

Beyond those uses, algae is a key ingredient in materials essential to a variety of industries. It’s often a key component of bioconcrete, the source of many bioplastics, and a growing source of agricultural biostimulants and fertilizers. Algae is used in aquaculture as feed for fish and shrimp, naturally imparting healthy antioxidants and omega-3 oils, along with appetizing colors, that don’t come from typical soymeal.

Looking at possibilities for expanding and improving the use of algae-based processes and technology to advance not only economic interests but also the greater societal good is the main thrust of research led by the three Fulton Schools faculty members on AzCATI’s leadership team. Each is contributing to innovation in what is called the Algae-Food/Energy/Water Nexus.

Research Professor Peter Lammers studies algae from acidic hot springs, applying his knowledge of molecular biology and environmental chemistry to create large-scale carbon-foundries that will fuel the future carbon economy.

Assistant Professor Taylor Weiss concentrates on making biochemical and biophysical advances, using synthetic biology and novel sensors to create and control the production of renewable biochemicals, sustainable agricultural additives, algal biofuels and products to improve human health.

Professor Shuguang Deng utilizes chemical engineering principles to develop adsorbents, catalysts and membranes for systems and technologies providing sustainable energy, chemicals, fuels and construction materials.

Research by Fulton Schools colleagues outside of AzCATI meshes with the center’s goals and helps support its ongoing projects.

Associate Professor Elham Fini is using an additive derived from algae to boost the resilience and reduce the emissions of asphalt — which is especially important in hot and sunny Arizona.

Professors Bruce Rittman and Rolf Halden’s work focuses on finding more effective methods of protecting and restoring the health of ecosystems.

In his Center for Negative Carbon Emissions, Professor Klaus Lackner is developing carbon capture technology to help pull harmful greenhouse gases out of the atmosphere.

Research capabilities in these and related areas over the years have brought AzCATI more than a dozen major projects funded by the U.S. Department of Energy, along with other projects supported by the Small Business Innovation Research programs of the U.S. Department of Agriculture and the National Institutes of Health.

Funding has also come from the Department of Energy’s Advanced Research Projects Agency-Energy, the Central Arizona Project — the aqueduct and canal system that brings water to much of central and southern Arizona — as well as numerous companies such as Xylem, a major multinational innovator in water technology.

Research collaborators rely on AzCATI’s expertise and creativity

Longtime AzCATI collaborators in industry, government agencies and research universities say the center has played an essential role in their research and development success.

Matthew Posewitz, a professor of chemistry at the Colorado School of Mines, has been in algae research field for more than 20 years and has worked on algae biofuels and related projects with support from the National Renewable Energy Laboratory and the Department of Energy.  

“Some algae technology advances were pioneered at ASU dating back decades ago,” Posewitz said, “and the people at AzCATI continue to perform that level of work. They have been consistently at the forefront of algae testbed productivity. We have always been able to rely on the competence and creativity of the people there.” 

Philip Pienkos has that same level of confidence in AzCATI’s researchers and technicians.

“I have always trusted them to do outstanding work and I always will,” said the biologist and recently retired emeritus scientist with the National Renewable Energy Lab.

His assertion is based on collaborations he was involved in with AzCATI since its early days, finding its leadership especially motivated to make breakthroughs in algae research.

“Once we decided what it was going to take to accomplish what we wanted to do, we could count on them getting the work done,” Pienkos said.

He recalls the first project he worked on with AzCATI researchers being an especially rewarding accomplishment. Together they provided the basis for a concept of an algae-based biorefinery, which led to the development of algae-based polyurethane, a plastic material with a plethora of practical uses.

Today, Pienkos is in the process of getting his own startup venture off the ground as a platform for commercializing urethane technology.

Helping to reverse direction on our unsustainable path

From a big-picture perspective, Lammers and Weiss say, solutions to the environmental threats posed by the increasing amounts of detritus — decomposing waste and debris — that is created by modern civilization lie at the nexus of AzCATI’s endeavors and related ASU research projects.

For example, conventional activated sludge treatment of municipal wastewater leads directly to 24 billion tons of carbon emitted as carbon dioxide. The AzCATI team is researching ways of using algae to turn wastewater treatment into a renewable carbon foundry that would replace petroleum as the primary feedstock for industrial carbon commodities. 

AzCATI’s leaders say that engineering algae can help society change its unsustainable course. Algae-based technologies and systems could provide alternatives to wasteful and unsustainable practices that are causing environmental deterioration.

The researchers envision such an advance enabling development of effective and economical methods to clean up the damage that has already been done, while also spurring the development of new products — along with creating new jobs to better support communities and economies in an ever-growing world.

LightWorks Director Gary Dirks, who led the effort to establish AzCATI, says the center is at the leading edge of realizing the full potential of algae-based technology “to turn what is in those waste streams into valuable products.”

Such advances can contribute to creating “more sources of fuel, food, raw materials and chemical feedstocks to improve life in the future,” Dirks said. 

Ram Pendyala, director of the School of Sustainable Engineering and the Built Environment, shares that outlook. AzCATI’s work “will lead to transformative algae-based technologies that fuel our societies and clean our environments in the years ahead,” Pendyala said.
