In this talk I will motivate and describe my ongoing body of work on using empirical auditing of differentially private machine learning algorithms as a complement to the theory of differential privacy. The talk will discuss how auditing builds on the rich theory and practice of membership-inference attacks, our work on auditing differentially private stochastic gradient descent, and directions for future work.</span><span style="font-family:Arial,Helvetica,sans-serif"><br></span></p></font></span></div></div><div><div><div><br></div><div><span style="color:rgb(0,0,0)"><b>Bio: </b>Jonathan Ullman is an Associate Professor in the Khoury College of Computer Sciences at Northeastern University. Before joining Northeastern, he received his PhD from Harvard in 2013, and in 2014 was a Junior Fellow in the Simons Society of Fellows. His research centers on privacy for machine learning and statistics, and its surprising connections to topics like statistical validity, robustness, cryptography, and fairness. He has been recognized with an NSF CAREER award and the Ruth and Joel Spira Outstanding Teacher Award.</span><br></div><div><b style="color:rgb(0,0,0);font-family:arial,sans-serif"><br></b></div><div><b style="color:rgb(0,0,0);font-family:arial,sans-serif">Host: </b><a href="mailto:avrim@ttic.edu" style="font-family:arial,sans-serif" target="_blank">Avrim Blum</a><br></div></div></div></div><div style="font-size:small"><br></div><div><font><font color="#0000ff">*</font>Access to this livestream is limited to <b><span>TTIC</span> / UChicago</b> (press panopto link and login to your UChicago account).</font><font size="1" style="font-size:small"> </font><br></div></div><div style="font-size:small"><div dir="ltr"><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br></div></div></div></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><span style="font-family:arial,helvetica,sans-serif;font-size:x-small">Mary C.
