Lisa’s research is focused on the characterization of Hot Jupiter’s atmospheres. Hot Jupiters are great candidates for photometric observations as the orbital period of these gas giants are short giving us many opportunities to observe transits and secondary eclipses. These giant exoplanets are also an excellent sample to test atmospheric theories in extreme environments. Her interest  lies in Hot Jupiters whose emission spectra are poorly fit by known spectral models. An example of such exoplanets is CoRoT-2b whose dayside emission spectrum exhibits by far the strongest broadband spectral feature of all short−period planets, and is  poorly fit by both radiative transfer and spectral retrieval models. Furthermore, the abnormally deep eclipse depth at 4.5 microns could not fit any atmospheric models, even in the absence of CO absorption. With our full observations of CoRoT-2b, it will be possible to confirm or reject previous unexpected results. Additionally, this will allow us to calculation the Bond albedo of this presumably tidally locked, quantify day-night heat transport, further constrain its atmospheric opacity via transit spectroscopy, and discriminate between astrophysical and atmospheric scenarios for its inscrutable eclipse spectra.

In parallel to her research, Lisa is also an active member of the McGill Physics Outreach group. From organizing public talks, visiting primary and secondary schools, and planning hackathons, the group attempts to engage the public of all ages and various backgrounds with physical sciences and astronomy.
