<div class="bio">
<p>I am a computer science faculty member at IIT Gandhinagar. My academic work is broadly around algorithms, structural graph theory, parameterized complexity, computational social choice, combinatorial games, and fair allocation.</p>
<p>These blogs separate different kinds of notes: paper-reading and mini-surveys, puzzle-like teaching prompts, reflective essays, poems, reviews of tools and workflows, experiments with AI, and visual or generative art.</p>
<p>The homepage is deliberately small: each section shows the two newest posts and links to that blog's RSS feed.</p>
