Students who arrive at UC Merced planning on specific careers often discover along the way that their interests — and strengths — are broader than they first imagined.

A new initiative called Education Tracks, or EdTracks, is designed to give students a flexible, low‑risk way to explore careers in education without delaying graduation or adding significant cost.

Avinav Biswas, a third‑year undergraduate majoring in biological sciences at UC Merced, has been named a 2026 Barry M. Goldwater Scholar, becoming the university’s first recipient of one of the nation’s most prestigious undergraduate awards for students pursuing research careers in science, engineering and mathematics.

The scholarship provides $7,500 annually to support tuition, fees, books and living expenses. It is awarded to students who demonstrate exceptional research achievement and promise, and who plan to pursue careers centered on scientific discovery.

Professors Asmeret Asefaw Berhe and Ming-Hsuan Yang have been named 2025 fellows of the American Association for the Advancement of Science, the world’s largest general scientific society and publisher of the Science family of journals.

They are among the nearly 500 scientists, engineers and innovators who have been recognized this year for their distinguished scientific and social achievements.

On most days, Reo Maynard’s life swings between two ecosystems: the microscopic world inside an ant’s gut and the sprawling one that stretches from Fresno to the Sierra Nevada mountains.

The 51-year-old Navy veteran, dad of two, screenwriter-in-waiting and newly minted Fresno City College faculty member is in his eighth year at UC Merced, earning his Ph.D. in Quantitative Systems Biology.

“I’ll be defending in May. The end is here,” he said, with the equal parts relief and wonder of someone who kept moving when the ground shifted beneath him.

Although the oceans are the least explored places on the planet, even their depths are not untouched by humans.

Drawing on more than 2,300 seawater samples collected across the Pacific, Atlantic and Indian Oceans, researchers found that hundreds of synthetic chemicals — many of them rarely monitored and originating from everyday products — are now woven into the fabric of marine organic matter.

UC Merced researchers are collaborating on a two-year research project to develop effective composting methods for cotton textiles.

The project explores manufacturing cotton waste scraps from clothing into compost to demonstrate efficient composting with the right recipe, and the compost’s ability to nourish soils without introducing pollutants, according to UC Merced’s project lead, Biyensa Dubiwak, a postdoctoral scholar in the Department of Life and Environmental Sciences.

When Professor Asmeret Asefaw Berhe arrived at UC Merced in 2009, she and her husband, Professor Teamrat Ghezzehei, were leaving major research institutions to join a brand-new campus in California’s Central Valley. It was a leap of faith — one made easier by the Sierra Nevada Research Institute.

As nations cut emissions that once fueled urban smog, scientists are discovering unexpected chemistry taking place in the atmosphere.

UC Merced Professor Xuan Zhang is leading a project to uncover how these chemical shifts could affect the air we breathe and the climate. The project is supported by a National Science Foundation CAREER Award.

Zhang is the 43rd researcher from UC Merced to earn a CAREER award from the NSF.

As the Hellman Fellowships celebrate their 30th year, three more researchers, one from each of UC Merced’s schools, have joined the prestigious ranks of recipients.

Electrical engineering Professor Qian Wang, sociology Professor Meredith Van Natta and Earth systems Professor Adeyemi Adebiyi will receive funding through their fellowships for projects they have proposed.

More than 100 million land mines remain buried around the world, posing a threat in approximately 70 countries and territories, and killing or injuring about 5,000 people, most of them civilians, every year. 

As the world’s geopolitical landscape shifts, nine scientists studying different aspects of warfare ecology from seven countries — Poland, Ukraine, Norway, Spain, the United States, Finland and Croatia — are warning against the growing deployment of land mines as countries bordering Russia withdraw from global conventions restricting their use.
