I am currently a tenure-track Assistant Professor leading VILA Lab at MBZUAI. I was a postdoctoral researcher in Professor Marios Savvides and Professor Eric Xing's group (2019-2022). My research interests span machine learning, computer vision, efficient deep learning, etc. Prior to CMU, I was fortunate to be a joint-training Ph.D student (2017-2019) in IFP group/UIUC, advised by Prof. Thomas S. Huang.

1. Multiple positions are available, including PhD, master, visiting student, Postdoc, etc. Please send me your CV if you are interested in working with me at MBZUAI.

2. We also have a few joint postdoc positions with CMU (starting from 2025), please reach out if you are interested.
(For RAs and visiting students, currently I only accept those who either plan to pursue your PhD in my group or are already senior PhD students at other universities seeking a short/long-term visit. If you do not meet these criteria, it is no need to apply for RA positions in my group. Also, I may not be able to respond to every inquiry, but I do go through all the emails I receive. Thanks for your understanding.)

Research Interest

My research interests focus on the broad areas of efficient deep learning, machine learning, computer vision and natural language processing. Specifically, I am interested in deep learning methods for image recognition and object detection, efficient architecture design and parameter-efficient finetuning strategies, etc. Recently, I focus on

  • Foundation Models in CV and NLP
  • Low-bit and Efficient Networks
  • Knowledge Distillation on Models and Datasets
  • Designing and Training Highly-efficient Network Architectures for CNNs and Transformers
  • Un(Self-)supervised / Weakly-supervised Learning
  • Image Understanding, Including Object Detection, Captioning and Fine-grained Recognition
  • Few-shot and Zero-shot Learning

Prospective Students: I am actively looking for self-motivated students (including graduate students and research assistants) who are interested in the areas of artificial intelligence, machine learning, VLM&LLM, deep generative networks, etc. I have several PhD/Master/RA openings starting in Fall 2025/2026 at MBZUAI. Please drop me an email with your CV if you are interested in joining.

Some ongoing projects in our lab for prospective students:
1. MBZUAI-LLM Project (SlimPajama-DC , Bi-Mamba , LLM360, GBLM-Pruner): Huggingface
2. OptiML: Optimizing Efficiency in Machine Learning (GLoRA, Partial Transfer, ViT-Slim): Github
3. Evolving Knowledge Distillation: The Role of Pre-generated Soft Labels (FKD, FerKD, SRe2L): Github
4. Pure Machine Learning Problems, such as: Dropout, Knowledge Distillation, BNN Optimization, etc.

MEAL V2: Boosting Vanilla ResNet-50 to 80%+ Top-1 Accuracy on ImageNet without Tricks
Technical report. Short version has been accepted in NeurIPS 2020 Beyond BackPropagation: Novel Ideas for Training Neural Architectures workshop.
Code & Models  |  arXiv Paper
We achieve 80.67% top-1 accuracy using a single crop-size of 224×224 on the vanilla ResNet-50, the first work that is able to boost vanilla ResNet-50 to surpass 80% on ImageNet without architecture modification or additional training data. Our result can be regarded as a new strong baseline on ResNet-50 using knowledge distillation.
