Research Interests

In the future, all computation will move to the Cloud. Meaningful Cloud computing research is fundamentally challenging: in addition to standing on sound theoretical grounds, it has to be deployed on real systems at a realistic scale, requires significant engineering effort, and often involves large teams and industry collaboration. I find this kind of research compelling because the problems are complex, intellectually challenging, require cross-disciplinary (economics, legal, privacy, …) solutions and have very high-impact. During my time as a PhD student, startup founder, postdoc at Yahoo! research, and research scientist at the Massachusetts Open Cloud (MOC), I was fortunate to be involved in projects where I had the opportunity to experience and develop the skills necessary to succeed in this kind of research. 

My research interests lie in the design/development of cloud-based bigdata platforms and improving the performance, security, or efficiency of cloud frameworks using machine learning and combinatorial mechanisms. My research target going forward is to start initiatives for cloud-assisted big data solutions for emerging applications such as healthcare, renewable energy, and crypto finance systems, while building on the projects I helped get started at MOC.

I also have extensive expertise in designing algorithms for graph analytics. I proposed approximation algorithms for identifying graph features and developed partitioning, replication, scheduling tools for parallel computations on large scale graphs. I plan to keep exploiting (and contributing to) fundamental computer science theory to improve performance and efficiency of Cloud applications.
