Nikhil Seshadri, an Indian American theoretical chemist and physicist who has spent his early career bridging the gap between abstract mathematics and the physical world, has been named a 2026 Hertz Fellow.
The prestigious award, granted by the Fannie and John Hertz Foundation, provides five years of funding to the nation’s most promising doctoral students in the applied physical and biological sciences.
In addition to financial support, the 19 new fellows join an interdisciplinary community of more than 1,300 Hertz Fellows worldwide, collectively responsible for some of the most significant scientific and technological progress of the past century.
“Year after year, the Hertz Fellowship identifies individuals whose ambitions go far beyond personal achievement. This class is no exception,” said Stephen Fantone, chair of the Hertz Foundation board of directors and president and CEO of Optikos Corporation. “Our newest Hertz Fellows are committed to solving problems that matter for our national security, our health and our future.”

Born in San Diego, California, Seshadri represents the high-achieving second generation of the Indian diaspora. His academic journey reflects a rigorous dedication to the sciences that often characterizes the Indian American experience, defined by a deep-seated respect for intellectual inquiry.
He earned a bachelor’s degree from Harvard University, completing a double concentration in chemistry and physics (specifically chemical physics) and computer science, alongside a secondary focus in mathematical sciences.
Seshadri’s research focuses on cavity quantum electrodynamics and open quantum systems. Currently a post-bachelor’s student at Los Alamos National Laboratory, he works with Dr. Yu Zhang on extending the Gutzwiller wavefunction method to account for nonlocal electron-photon interactions. This specialized work seeks to create a unified framework for studying how such interactions influence quantum phases, which could eventually allow scientists to tune material properties.
The foundation for Seshadri’s success was laid early. While still in high school in San Diego, he began working on quantum thermodynamics with Professor Michael Galperin at the University of California, San Diego.

This partnership led to published research in Physical Review B and the Journal of Chemical Physics. During his time at Harvard, he continued this trajectory, engaging in research involving porphyrin chemistry and X-ray diffraction.
Despite the intensity of his scientific pursuits, Seshadri maintains a profound connection to the arts, a balance frequently seen in the cultural upbringing of many South Asian families.
He is an accomplished musician who plays both the violin and the piano. At Harvard, he was an active member of the Harvard Baroque Chamber Orchestra, often performing at the Harvard Memorial Church. His passion for baroque music serves as a creative counterweight to the precision required in quantum mechanics.
In the fall of 2026, Seshadri will transition to the California Institute of Technology to begin his doctoral studies. As he moves forward, his work continues to represent the significant contributions Indian Americans make to the American scientific landscape.
By applying rigorous mathematical methods to fundamental problems in chemistry, Seshadri is helping to shape the future of how we understand the very building blocks of the universe.
