Research Interests
Industrial grade machine learning algorithms and systems at scale, which lies at the intersection of machine learning, distributed systems, edge/cloud/sky computing, blockchain, and security/privacy. My recent focus:
- Machine Learning System and Algorithm Co-design:
1) End-to-end MLOps platform for data preparation, training, inference, deployment, collaboration, monitoring, observability, security/privacy.
2) device-edge-cloud federated/distributed/collaborative machine learning
3) Security/privacy for ML: MPC (secure aggregation), DP (differential privacy), FHE (fully homomorphic encryption), TEE (Trusted Execution Environment)
4) Integrated Edge ML engine for training and inference
5) MLOps with strong observability and monitoring capability to mitigate issues from data drift over time, skewed data distribution between training and deployment, and system heterogeneity
6) training efficiency on resource-constrained devices: reducing memory/energy/computation/communication cost for training large models on a resource-constrained commodity device;
7) system for decoupling storage and computing resource for model training;
8) serverless computing for cloud-based distributed training and multi-tanant training system;
9) multi-cloud machine learning and data analytics - Responsible and Trustworthy Data Economy: blockchain-empowered machine learning and data analytics: zero-knowledge proof (ZKP), verification, proof of contribution, privacy protection, and robustness to malicious/cheating users.
- Trustworthy Federated Learning: achieving high model performance on decentralized data under constraints of security, privacy, label deficiency, and system resources in a lifelong manner via the operational and practical system and ML co-design
- Machine Learning Algorithms with Strong Demand in Real World: computer vision, natural language processing, graph learning (graph neural networks), recommendation systems, time-series forecasting
- General Computer Systems: distributed/cloud/edge systems, mobile systems, open source library, product design

- 03/30/2022: I received a very moving graduation gift: a Tang Dynasty poem (year 618-907) and a plum picture painted by a Qing Dynasty person that my labmate just bought from an American auction. The mood in the poem is very in line with the first two years when I came to the United States. I am lonely away from the crowd and accumulate silently. It is also the mood that should be possessed in the deepest part of scientific research. Here is the translation.
- 03/25/2022: I passed my Ph.D. defense. See my acknowledgment here. The thesis manuscript is maintained here.
- 11/21/2021: FL4NLP Workshop Proposal (Federated Learning for Natural Language Processing) has been accepted to ACL 2022. Welcome to submit your excellent works!
