About me:
My research interests include supergravity, string theory, extra-dimensional model phenomenology, neutrino physics, and cosmology.
In addition, I am also a member of KATRIN and JUNO collaboration.
My joint research with Ignatios Antoniadis and Hiroshi Isono on Dark Dimension & KATRIN experiment has attracted the attention of Popular Mechanics magazine: https://www.popularmechanics.com/science/a71166325/ghost-particles-dark-dimension/
