<h5>About Me</h5>
<p>
I focus on detecting unexpected phenomena, with applications to scientific research and AI safety.<br/>
<br/>
I am now a post-doc at <a href="https://engineering.nyu.edu/" target="_blank"> New York University</a>, working with Prof. <a href="https://www.cs.huji.ac.il/~ydidh" target="_blank"> Chinmay Hegde</a>.<br/>
Prior to that I received my PhD at the <a href="https://www.vision.huji.ac.il/main/" target="_blank">Hebrew University</a>, supervised by Prof. <a href="https://www.cs.huji.ac.il/~ydidh" target="_blank">Yedid Hoshen</a>.<br/>
You can also check my personal <a href="https://www.cs.huji.ac.il/w~nivc/riddles.html" target="_blank">site</a> with some nice riddles and more.<br/>
