About me
Since April 2019, I am a postdoctoral researcher at the Department of Electrical Engineering and Information Technology in Politecnico di Bari, Italy working with Prof. Tommaso di Nioa. Before that, I was a research collaborator at Information Retrieval Laboratory at University of Milano Bicocca, Italy for 1 year. I was awarded a Ph.D. title with Distinction in computer science with a focus on "Recommender Systems" from Politecnico di Milano, Italy in 2018. During my Ph.D., I was a visiting researcher at Johannes Kepler University (JKU) in Linz, Austria for a period of 6 months. I obtained my MSc in Electrical Engineering at the Chalmers University of Technology in Gothenburg, Sweden as the First ranked (highest GPA) graduate.
I have (co-)authored many refereed articles at internationally recognized conferences and peer-reviewed journals among others published in Journal of UMUAI, IEEE TKDE, Journal of Data Semantics, ACM RecSys, ACM MMSys, ACM CHI in addition to a 2018 US Patent. I have served as a PC member or reviewer for different top-tier conferences and journals. I have been involved in organization of the ACM RecSys Challenges 2019 (hosted by Trivago) and ACM RecSys Challenges 2017 (hosted by Xing) as part of the ACM Conference on Recommender Systems as well as MediaEval Benchmarking Initiative for Multimedia Evaluation with the focus on leveraging multimedia content for enhancing recommendation of different products (media or non-media items). To know more about my research activities, see my publication page.
