The case for technosignatures: Why they may be abundant, long-lived, highly detectable, and unambiguous
The intuition suggested by the Drake equation implies that technology should be less
prevalent than biology in the galaxy. However, it has been appreciated for decades in the …

Probing the capability of future direct-imaging missions to spectrally constrain the frequency of Earth-like planets
A critical question in astrobiology is whether exo-Earth candidates (EECs) are Earth-like, in
that they originate life that progressively oxygenates their atmospheres similarly to Earth. We …
