Division of Science

Driven by curiosity
The FAS Science division spans the biological and physical sciences. FAS scientists engage in observation of our world and the universe beyond it, laboratory-based experimentation, computational analysis, and the pursuit of questions driven by curiosity about how the world works. Their expertise covers the microscopic and the gargantuan: from the smallest cells, atoms, and particles of matter, to the physical and biological systems that shape life on earth, to the stars and planets.
The divisional dean of Science is Larry Gladney.

Science departments and programs
The FAS is home to three departments in the biological sciences--Ecology and Evolutionary Biology; Molecular Biophysics and Biochemistry; and Molecular, Cellular, and Developmental Biology--and five in the physical sciences--Astronomy, Chemistry, Earth and Planetary Sciences, Mathematics, and Physics.

New study offers a double dose of ‘hot Jupiters’
Yale astronomers show how the long-term evolution of binary star systems with two planets and two stars can produce something rare: double hot Jupiters.
Mapping binary star systems helps astronomers find new planets
Earth.com interviews Malena Rice, Assistant Professor of Astronomy, about her recent study which maps binary stars.
Evolutionary biologists reveal lizard ancestors that endured a cataclysmic asteroid strike
A Yale-led study has found that night lizards, small reptiles that inhabit North and Central America, survived the extinction event that wiped out most life on Earth — despite living near ground zero.
Yale paleontologists co-author study on key bone in bird wrists
The evolutionary path from dinosaurs to birds included the development of a tiny wrist bone that ultimately proved crucial for stabilizing wings in flight.
Expanding understanding
Curiosity-driven research expands our understanding of the world and underpins virtually all applied research, innovation, and technological development. When researchers in Yale’s Faculty of Arts and Sciences follow their curiosity, it takes them down unexplored pathways, for the benefit of future generations.
