About

PhD student at the Machine Learning Group under the supervision of Frank Hutter.
I obtained my Master's degree in Computer Science with honours at the University of Freiburg with a final grade of 1.0 under the German grading system.
Previously, I have also obtained All India Ranks of top-100 twice in the GATE Computer Science examination (out of more than 115,000-150,000 candidates).
GRE Score: 170 (Quantitative), 164 (Verbal), 4.0 (Analytical Writing Assessment).
