My current research concentrates on the discovery and characterization of transiting exoplanets, a topic on which I started working while I was a Clay Fellow at the CfA, and on small telescope instrumentation. I'm actively involved in HATSouth, a project that has built a global network of southern hemisphere automated wide-field telescopes to detect transiting exoplanets. I was the PI of CHAT, a now retired 0.7m automated telescope dedicated to exoplanet light curve observations at Las Campanas Observatory. We are working on the final stages of commissioning of HATPI, an innovative instrument of which I am co-PI and that will image the whole sky visible from Las Campanas (above 30 deg elevation) with high photometric precision and a cadence of 30 seconds.

On the characterization front, I am involved in atmospheric studies, and particularly in using transmission spectroscopy to probe the atmospheric composition of transiting exoplanets. I was co-PI of the ACCESS survey which used Magellan@LCO to get transmission spectra for a sample of transiting exoplanets and was a pioneer effort in ground based transmission spectroscopy. I am also very interested as well in discovering and characterizing long period planets (P>10d) around nearby stars in order to characterize the densities of these systems whose structure is not affected significantly by the stellar flux. Finally, I am also co-leading efforts to discover giant planets around M dwarfs, and am the PI of a JWST program to study the atmosphere of TOI-3235b.

I am a partner of Obstech SpA, a company that developed a new observatory from scratch in the north of Chile (more specifically in the Río Hurtado valley). Our observatory, named "El Sauce", is about 26km south of Gemini and hosts over 140 telescopes. As part of this effort we have also developed some devices, such as all-sky cameras, and a telescope control system.
