<h1>Biography</h1>
<p>Currently, I am a senior deep learning software engineer at NVIDIA. I obtained my Ph.D. degree in Electrical and Computer Engineering at
<a href="https://engineering.purdue.edu/ECE" target="_blank" rel="noopener">Purdue University</a>, advised by
<a href="https://engineering.purdue.edu/ECE/People/ptProfile?resource_id=3085" target="_blank" rel="noopener">Prof. Kaushik Roy</a>. While there, I focused on developing energy-efficient and robust deep learning algorithms with special interests in spiking neural networks and computer vision for event-based cameras.</p>
