About me
I am Shivangi Yadav, a Research Associate-I in the Department of Mathematics, Indian Institute of Science, Bengaluru, where I work under the mentorship of Prof. Apoorva Khare. My research is centered on problems involving matrix positivity and preserver problems. More specifically, I work on characterizing sign regularity and its preservers.
