About me

I am a 3rd year physics PhD student at Harvard University originally from Kingston, Jamaica, advised by Catherine Zucker. My primary interest is in understanding how the size of astrospheres, and particularly the heliosphere, evolve as a star orbits the galaxy and encounters structures in the interstellar medium (ISM). Encounters with dense molecular clouds (eg. Opher et. al. Aug. 2024 and Opher et. al. Sep. 2024) are suspected to provide a large enough pressure to compress the protective bubble carved out by the solar wind, thereby exposing the Earth to the ISM. This may have effects on climate through, for example, the influx of hydrogen from the ISM as well as an increase in the cosmic ray flux. I am thus interested in characterizing the conditions required for such “descreening” events, as well as the frequency and duration of the descreening events so as to better understand their impact on the history of the Earth’s climate and the impact on planets orbiting other stars.
