I am an Associate Professor in the Department of Economics at University College London. I am a Research Affiliate of the Centre for Economic Policy Research (CEPR), the Centre for Microdata Methods and Practice (CeMMAP), and Institute for Fiscal Studies (IFS). My research interests combine time series econometrics and empirical macroeconomics. I primarily focus on developing new methods for reliable causal inference on macro-policy questions, with particular interests in statistical identification and testing identification conditions. I have also contributed research on HAR inference, the real-time measurement of real activity, and clustering algorithms. Empirically, my work centres on the effects of monetary and fiscal policy. I hold a Ph.D. in Economics from Harvard University and an A.B. in Economics from Princeton University. I am a member of the Editorial Board of the Review of Economic Studies, and an Associate Editor of the Journal of Econometric Methods. My research is funded in part by a European Research Council Starting Grant, StG-101161596 CreMac.
