I am an Assistant Professor of Computer Science at Boston University, where I co-lead the Complex Analytics and Scalable Processing (CASP) Systems lab.

I enjoy doing research on multiple aspects of data-centric systems. Recently, my team and I have been focusing on designing self-managed systems for data stream processing, scaling graph Machine Learning training on modern storage, and developing practical solutions for private collaborative analytics with Multi-Party Computation.

Before joining BU, I was a postdoctoral fellow at ETH Zurich, where I was awarded the ETH Zurich Postdoctoral Fellowship. I received my PhD from KTH Royal Institute of Technology in Stockholm, Sweden and Universite Catholique de Louvain in Belgium, after completing a joint doctoral program as an EMJD-DC fellow.

I am very lucky to advise the following PhD students:

Muhammad Faisal (6th year)
Yuanli Wang (5th year)
Lei Huang (5th year, co-advised with Abraham Matta)
Naima Abrar Shami (3rd year)
Yuhang Song (2nd year)
Sakshi Sharma (1st year, co-advised with John Liagouris)

For a full list of students working with me, visit the CASP Systems Lab webpage.
