Overview

Research -  Detecting and Characterizing exoplanets with particular interest in studying their architecture; Stellar models to better understand stellar activity for detecting low-mass (Earth-like) planets around solar-type stars (as in upcoming Terra Hunting Experiment).

Outeach - I believe public outreach is a part of our responsibility as researchers. I have been engaged in various outreach activities (see my website for details), most recently (July 2022) I gave a public talk on "Discovering Earth-like planets in the celestial neighbourhood" in the National Science Center, Leicester.
