It is my great pleasure to welcome you to my KTH homepage. I am a joint Researcher between the RISELab at UC Berekely and the Division of Network and Systems Engineering at KTH Royal Insitute of Technology. My research focuses on optimization theory and machine learning, with applications in networking. You can visit my old personal homepage here, which may include some more academic and professional records.
