✨ Welcome to the Homepage of Dr. Clark Baker ✨

:: About Me ::

Hello! I am a Senior Postdoctoral Researcher at ETH Zurich and the University of Cambridge. My primary focus is on the detection and characterization of exoplanets by building and using high-precision radial velocity instrumentation.

When I'm not building this high-end, technically-advanced website, I am in the lab working on the next generation of extreme precision radial velocity spectrographs.

:: Current Research NEW! ::

• Earth-Twin Surveys & EPRV: Developing next-generation extreme-precision radial velocity (EPRV) spectrographs and leading the development of the HARVY survey facility at ETH Zürich to search for Earth-like planets around solar-type stars.
• The Terra Hunting Experiment & HARPS3: Building HARPS3 and contributing to the Terra Hunting Experiment to measure precise radial velocities over decade-long timelines to hunt for Earth-twins.
• Simultaneous multi-band photometry: Building DUET, a simultaneous InGaAs-CCD, IR-Vis, dual-channel imager for dual band photometry at the SPECULOOS-Southern Observatory to characterize transiting terrestrial exoplanets orbiting ultra-cool dwarfs.
