Life is about exploring

From 2021 Nov., I am a Posdoc at Tsinghua University, working with Prof. Xiaolin Hu.  From 2018 to 2021,  I was PhD fellow in Audio Analysis Lab​ at Aalborg University, Denmark. I worked on multi-discipline including  distributed signal processing, secure multiparty computation, privacy and security. My PhD thesis is  'Privacy-Preserving distributed processing over networks' under supervision of Professor Mads Græsbøll Christensen and  Professor Richard Heusdens.  In  2019, I visited CAS group in Delft University of Technology (TUDelft)  as a visiting PhD

Involved  project

Sensing the world without violating privacy

Driven by the concern of private data abuse in the current 'Big Data' word. I was working on a very interesting project called 'SECURE' (Secure Estimation and Control Using Recursion and Encryption) at Aalborg University, Denmark.  It is an interdisciplinary project that requires techniques from distributed optimization, information theory, statistics, differential privacy, cryptography, security, and more. My main research focus is to design privacy-preserving protocols for distributed processing over networks.  I am particularly interested in computationally efficient solutions for practical scenarios such as resource-constrained wireless sensor networks.
