Besides, I received B.Eng in Materials Science and Engineering at South China University of Technology. My research interest lies in combining Artificial Intelligence with interdisciplinary science and engineering problems. My current research focuses on implementing and improving foundation models for material discovery and leveraging scientific machine learning for electrolyte optimization. I believe that deep learning models are able to learn representations from data so that we can understand scientific problems from a data science view, which is a significant transformation from traditional research strategies. diff --git a/_pages/cv.md b/_pages/cv.md index 6034bfa6fa1b2..3e86511c83b27 100644 --- a/_pages/cv.md +++ b/_pages/cv.md @@ -7,15 +7,15 @@ redirect_from: - /resume --- -You can download my [CV](http://ChangwenXu98.github.io/files/CV.pdf) (last updated September 2023) +You can download my [CV](http://ChangwenXu98.github.io/files/CV.pdf) (last updated June 2024) {% include base_path %} Education ====== * Ph.D. in Mechanical Engineering, University of Michigan, 2027 (expected) -* B.E. in Materials Science and Engineering, South China University of Technology, 2021 * M.S. in Computational Materials Science and Engineering, Carnegie Mellon University, 2022 +* B.E. in Materials Science and Engineering, South China University of Technology, 2021 Work experience ====== @@ -53,7 +53,7 @@ Blog Posts Professional Services ====== -* Reviewer: NeurIPS'23, ICLR ML4Materials Workshop'23, ICML SPIGM Workshop'23 +* Reviewer: NeurIPS'23-24, ICLR'24, ICML'24, ICLR ML4Materials Workshop'23, ICML SPIGM Workshop'23-24, ICML AI4Science Workshop'24 Skills ====== diff --git a/_talks/2024-04-03-Cloud.md b/_talks/2024-04-03-Cloud.md new file mode 100644 index 0000000000000..678b8cdc455ff --- /dev/null +++ b/_talks/2024-04-03-Cloud.md @@ -0,0 +1,14 @@ +--- +title: "CLOUD: A Scientific Foundation Model for Crystal Property Prediction" +collection: talks +type: "Poster" +permalink: /talks/2024-04-03-Cloud +venue: "MICDE Scientific Foundation Model Conference" +date: 2024-04-03 +location: "Ann Arbor, MI" +--- + + +**Abstract** + +Property prediction of crystals is crucial for material design.
