Karmela Padavic‑Callaghan is a Croatian‑born journalist, writer, educator, and scientist based in New York, whose work bridges physics, materials science, and quantum technology. Their background in theoretical condensed matter physics and AMO physics shapes a distinctive voice in science communication, blending technical depth with cultural and creative insight.

Before becoming a full‑time science writer, Padavic‑Callaghan earned a PhD from the University of Illinois Urbana‑Champaign, where their research explored ultracold atomic systems, quasiperiodicity, and novel geometries—including experiments conducted in microgravity. Their academic work appeared in peer‑reviewed journals such as Physical Review Letters and New Journal of Physics. During this period, they also engaged in art‑science collaborations, co‑developing a physics‑and‑art course and contributing to the devised theatre project Quantum Voyages.

Today, Padavic‑Callaghan is a physics reporter at New Scientist, covering cutting‑edge developments in quantum technology, materials science, and fundamental physics. Their freelance writing has appeared in Wired, Scientific American, Slate, MIT Technology Review, Quanta Magazine, and Physics World. They previously taught physics and mathematics at Bard High School Early College in New York and remain deeply committed to science education, equity, and community‑building within STEM. Their first book, Entangled States: A Life According to Quantum Physics, is forthcoming from Beacon Press.
