Kushal Lodha

I am a fourth-year Ph.D. student in the Cosmology group at KASI (advisor: Prof. Arman Shafieloo). I develop robust, model‑independent, data‑driven methods for cosmological inference with DESI and related surveys, testing dark energy and modified gravity beyond the standard $\Lambda\rm CDM$ paradigm.
