About Me

I come from the smallest and most densely populated country in Central America (hint). I did my undergraduate and graduate studies in Toulouse, France. After many trials and tribble-ations, I obtained my Ph.D degree from Nagoya University, under the supervision of Prof. Kazuo Shiokawa.
Since then, I've spent a very sunny year as a visiting scholar at the ATMOS department of UCLA working with Jacob Bortnik's group. Then followed 2 years in the 'cold' city of Sendai as a JSPS post-doctoral fellow with my host Prof. Yuto Katoh at STPP laboratory (Tohoku University).

After becoming a YLC Designated Assistant Professor, I leveled up to Associate Professor at ISEE in Sept. 2020. I am affiliated to the Ground Network Observation Group and the Center for International Collaborative Research

My research project is mainly on VLF/ELF emissions, their physical properties, generation and propagation. I mainly work with ground and satellite simultaneous and conjugated VLF events, but I am also interested in ionospheric physics. I'm an active member of VERSIM and co-founder of their Journal Club.

I love science, sports, reading and travelling. I also spend my free time watching science fiction and classic movies, keeping up with astronomy and photography. Always enjoying a cup of hot tea on a rainy day (or any day!). Proud member of the STEL's futsal team.

Inspiring quotes

  • Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar", every "supreme leader", every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam.

    Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space
  • The mind is not a vessel to be filled, but a fire to be kindled.

    Plutarch
  • It's not a silly question if you can't answer it.
