General Info

Welcome to my homepage. I am an astrobiologist, currently working at The Carl Sagan Institute at Cornell University, New York. My path into astrobiology took many twists and turns, meandering from physics to environmental biology and finally to astronomy. My interests lie firmly at the intersection between astronomy, biology and geophysics, which is a perfect place from which to explore questions about how life would influence exoplanet atmospheres, climates, appearances and detectable biosignatures. This involves combining information about a planet's size, mass, location and potential atmospheric composition, with details about its host star, while also exploring the physical and evolutionary limits of biology under the environmental conditions that could exist on a given planet. The results of work like this not only help us to determine how to search for life on distant alien worlds, but can also help us to build on our understanding of the complex interplay between the atmosphere, geosphere and biosphere here on Earth. This connection between other worlds and our own is the driving force behind my work. My research so far has encompassed everything from exploring exotic forms of photosynthesis on planets with two suns, to investigating the types of biospheres that could thrive on UV-irradiated worlds, and even looking at where the last puddle on Earth may be in the far-future and what this would mean for the search for life in the Universe
