My research interests encompass large-scale search and recommendation in various domains, including the Web, social media, and enterprises. As a result of my work, I have contributed to the open-source Terrier Information Retrieval platform, and published research papers in several major academic venues. In particular, I am a regular speaker and program committee member of several premiere conferences in IR, including SIGIR, CIKM, WWWWSDMRecSysECIR, ICTIR, AIRS, and SPIRE. I received the best paper award at RecSys 2015 and best paper runner-up award at RecSys 2020. I served as sponsorship co-chair for WSDM 2016, general co-chair for RecSys 2020, tutorial co-chair for SIGIR 2021, and currently serve as steering committee member for RecSys, and as a member of the editorial board of ACM Transactions on Social Computing and Foundations and Trends in Information Retrieval.
