Biography

Lucas Macri works on the Extragalactic Distance Scale, studies of electromagnetic counterparts to gravitational-wave sources, and large-scale galaxy flows. The main focus of his research is on Mira and Cepheid variables, which he studies using the Hubble Space Telescope and many ground-based observatories. One of the goals of his research is to measure a more precise value of the Hubble constant, to better constrain the equation of state of dark energy and test the current cosmological model.
