<p>I am a business school assistant professor, and I received my PhD in operations research. My research interests involve data-driven decision making in the healthcare space, with a focus on designing combination drug therapies for advanced cancer and on designing population screening strategies for cancer. My Erdos number is 3.</p>

<p>On Stack Overflow, I'm most active in <a href="/questions/tagged/mathematical-optimization" class="post-tag" title="show questions tagged &#39;mathematical-optimization&#39;" rel="tag">mathematical-optimization</a> (where I am the first recipient of a bronze badge) and <a href="/questions/tagged/r" class="post-tag" title="show questions tagged &#39;r&#39;" rel="tag">r</a>. I most enjoy answering questions that either deal with code optimization or mathematical optimization. My favorite answers I've contributed so far has this flavor:</p>

<ul>
<li><a href="http://stackoverflow.com/a/31037761/3093387">Given island and water locations on a grid and the cost of building a bridge on each water square, where should you build bridges to connect the islands at minimum cost?</a></li>
<li><a href="https://stackoverflow.com/a/59684495/3093387">Most efficient way to calculate function with large number of parameter combinations</a></li>
</ul>

<p>When I'm not working or on Stack Overflow, you might find me playing my favorite physical sport (tennis), playing my favorite mental sport (bridge), or playing with my cat Neptune (pictured).</p>
