<h1>Research</h1>
</header>
<p> My main areas of interest are general relativity, quantum field theory and black holes. Over the past few years my research has been directed towards following topics:
<ul>
<li>Asymptotic Symmetries and Soft Theorems</li>
<li>Black hole thermodynamics</li>
<li>Quantum Information & Entropy </li>
<li>Gravitational Memory Effect </li>
<li>Quasi normal modes of black holes</li>
<li>Non linear dynamics and infectious disease modelling.</li>
<li>Open quantum systems</li>
</ul>
<p>A very useful resource for gravitational physics: <a href="https://www.einstein-online.info/"> here </a></p>
<p>I am in-charge of Quantum Information & Scientific Computing Lab </a></p>
