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.

Physics Ph.D. candidate Arabi Seshappan added two prestigious fellowships to her curriculum vitae: the Chateaubriand Fellowship in Science, Technology, Engineering Mathematics & Biology-Health and the UC President's Pre-Professoriate Fellowship.

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.

Mariel Garcia accepted a welcoming handshake from the chief of staff for state Sen. Tim Grayson. A large photograph of rolling hills at sunset near Walnut Creek, a city in Grayson’s district, dominated a wall in the compact reception room.

“Good to meet you,” said the chief of staff, Aaron Moreno. “We’ll make sure to get whatever you need.”

Two UC Merced graduate students and an alum from the School of Natural Sciences were recently awarded fellowships from the highly competitive National Science Foundation Graduate Research Fellowship Program.

This year, NSF awarded 1,000 GRFP fellowships compared to about 2,000 in previous years.

UC Merced physics graduate student Sameen Yunus has been awarded a prestigious fellowship allowing her to spend the next three years working at Lawrence Livermore National Laboratory, conducting experiments and simulations that could lead to faster fusion ignition.

The UC-National Lab In-Residence Graduate Fellowship is designed to help graduate students complete their theses. Yunus, a third-year Ph.D. candidate, will work on experiments that complement her computational work in Professor David Strubbe’s lab.

Vice Chancellor for Research, Innovation and Economic Development Gillian Wilson has been named a 2024 Fellow of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society and publisher of the Science family of journals.

Being elected an AAAS Fellow is one of the most prestigious honors awarded by the association. Wilson is one of only eight astronomers honored this year.
