About
Hali Jakeman is a pioneering instrument scientist whose work is reshaping the frontiers of high-resolution spectroscopy and exoplanet detection. Her research centers on developing advanced optical technologies—most notably silicon immersion gratings (SIGs)—and building compact, robotic spectrographs for extreme-precision radial velocity surveys. Jakeman’s major contribution includes demonstrating that SIGs can deliver a 3.4× gain in dispersion or a ~10× reduction in instrument volume compared to conventional echelle gratings, enabling high-resolution infrared spectroscopy in dramatically smaller packages. Her most-cited paper (2012, 8 citations) lays the foundation for this innovation. She also led the development of the TOU spectrograph, a robotic, very-high-resolution (R=100,000) optical instrument deployed on the 2-meter Automatic Spectroscopy Telescope. During its pilot survey, TOU achieved on-sky Doppler performance capable of detecting low-mass planets, targeting the elusive population of close-in super-Earths. With citation counts ranging from 3 to 8, Jakeman’s work is steadily gaining recognition for its practical impact on instrument miniaturization and exoplanet science. Her achievements promise to accelerate the discovery of Earth-like worlds around nearby stars.
