Fellowships provide $75,000 in funding for early-career researchers in fields including chemistry, physics, neuroscience and mathematics

Three University of Colorado Boulder faculty members have been selected to receive prestigious in 2026. Winners receive a two-year, $75,000 fellowship that can be used flexibly to advance their research.

The three College of Arts and Sciences faculty members are:

• Erica Nelson, assistant professor in the��Department of Astrophysical and Planetary Sciences, for physics.
• Andres Montoya-Castillo, assistant professor in the��Department of Chemistry, for chemistry.
• Kelsie Eichel, assistant professor in the��Department of Molecular, Cellular and Developmental Biology, for neuroscience.

“The Sloan Research Fellows are among the most promising early-career researchers in the U.S. and Canada, already driving meaningful progress in their respective disciplines,” said Stacie Bloom, president and CEO of the Alfred P. Sloan Foundation, in announcing the winners Tuesday. “We look forward to seeing how these exceptional scholars continue to unlock new scientific advancements, redefine their fields and foster the wellbeing and knowledge of all.”

For 2026, the Alfred P. Sloan Foundation named 126 early-career researchers—including Nelson, Montoya-Castillo and Eichel—as�� award winners. Fellows from this year’s cohort were drawn from 44 institutions across the United States and Canada.

Since the first Sloan Research Fellowships were awarded in 1955, 60��faculty from С���� Boulder have received one, including this year’s winners, according to the Alfred P. Sloan Foundation.

“I’m delighted and honored to receive the support of the Sloan Foundation,” Montoya-Castillo said. “I’m especially grateful to my group, mentors and senior colleagues, both at С���� and beyond, who have been immensely supportive and kind.”

“It’s a big honor to be recognized by the Sloan Foundation,” Eichel agreed, adding that she is appreciative of the funding for her research. “My lab studies a fundamental question in cellular neuroscience—how neurons build and maintain their polarized architecture. This polarized architecture enables the nervous system to communicate, adapt and ultimately generate behavior. By uncovering the core principles that govern neuronal function, our work will lay the groundwork for developing new strategies to restore neuronal function in neurological diseases.”

Nelson said she is thrilled to be named a Sloan Research Fellow and added that the fellowship funding will be a valuable asset to her research.

“We’ve discovered mysterious red objects in the early universe with the James Webb Space Telescope that challenge��what��we thought we knew about the first galaxies and black holes. This fellowship provides crucial support to determine what these objects really are: Are they massive galaxies or a never-before-seen phase in the formation of supermassive black holes? Whatever the answer, it will fundamentally reshape our understanding of cosmic dawn in our universe,” she said.

Sloan Research Fellowships are considered one of the most prestigious awards available to young researchers—in part because so many past fellows have gone on to become distinguished figures in science. To date, 59 fellows have won a Nobel Prize, 72 fellows have received the National Medal of Science, 17 have won the Fields Medal in mathematics and 25 have received the John Bates Clark Medal in economics.

Open to scholars in seven fields—chemistry, computer science, Earth systems, economics, mathematics, neurosciences and physics—more than 1,000 researchers are nominated by their fellow scientists each year, according to the Alfred P. Sloan Foundation. The organization said winners are selected by independent panels of senior scholars based upon their research accomplishments, creativity and potential to become leaders in their fields.
