In the eld of exoplanet studies, something that has made me very interested and excited is thediscovery of all these di erent planets that we have no analogs in our own solar system. So
these are the planets that are more massive than the Earth and less massive than Neptune. So
the so-called Super-Earths are Sub-Neptunes. The reason they're so interesting is we don't know
what the composition is or the structure of these planets are. So people will talk about maybe the
Super-Earths are habitable, but we don't even know if we can have a rocky, hard surface for
people to live on, on a Super-Earth. So I'm very interested in studying the structure and the
composition of these planets. So SETI Institute stands for the Search for Extra-Terrestrial
Intelligence. It has two main parts; the SETI part where they have radio telescopes where they
listen to see if they can hear any signals that could maybe become from alien sources. Another
part of the SETI Institute is The Carl Sagan Institute, where people are doing work on trying to
understand planets and habitability and asteroids. There's people who work on Mars missions.
Then a lot of people work on the Kepler project of looking for planets and so my work is to help
look for those planets and then with doing the microlensing search using the Kepler eld, then
we are also getting an understanding of the di erence occurrence rates of compact objects and
just understanding stellar evolution and the systems that you might be nding planets in.
