Welcome!

Hi there! I’m Alex, an NSF Graduate Research Fellow in the Department of Astronomy at Columbia University. My research focuses on the search for exomoons — moons orbiting planets outside our Solar System — using survey and targeted time-domain photometry. There aren’t very many of us in this field right now, so there’s a lot to do! And we’re truly at the very early stages of this work. I’m enormously proud and absolutely thrilled to be a part of this endeavor. It’s a great privilege.

Searching for exomoons is exceptionally challenging, largely because we’re really pushing the limits of what the data can support, and increasingly, we tend to think these moons will be found at significant distances from their host stars. This poses all kinds of difficulties for detecting them — they’re less likely to transit, they transit less often, and there are precious few targets in the literature for which we have all the information we need to perform targeted follow-up observations. How do we get around these challenges? I haven’t got all the answers, yet. But it’s my job to figure it out.
