+
+Welcome to the official blog of **Xtra Computing Group** at the National University of Singapore.
+
+This is a space for lab members, collaborators, and friends to share research ideas, technical write-ups, project updates, and anything else that might be useful to the systems and ML community.
+
+<!-- truncate -->
+
+## What We Work On
+
+Xtra Computing Group sits at the intersection of **data management systems**, **parallel computing**, and **machine learning**. We build things that are fast, scalable, and principled — from GPU-accelerated ML libraries to federated learning benchmarks to LLM privacy toolkits.
+
+A few highlights from recent work:
+
+- **[LLM-PBE](https://github.com/Xtra-Computing/LLM-PBE)** (SIGMOD 2024, Best Paper Nomination) — a toolkit for evaluating data privacy risks in large language models.
+- **[VertiBench](https://github.com/Xtra-Computing/VertiBench)** (ICLR 2024) — advancing feature distribution diversity in vertical federated learning benchmarks.
+- **[Model Go](https://github.com/Xtra-Computing/ModelGo)** (WWW 2024, Oral) — a practical tool for machine learning license analysis.
+- **[ThunderGBM](https://github.com/Xtra-Computing/thundergbm)** / **[ThunderSVM](https://github.com/Xtra-Computing/thundersvm)** — GPU-accelerated gradient boosting and SVM libraries with thousands of users.
+
+## Who Can Write Here
+
+Everyone. Lab members, visiting researchers, collaborators, and anyone in the community with something interesting to say. If you have a research insight, a systems trick, a paper walkthrough, or a tutorial — this blog is for you.
+
+See [CONTRIBUTING.md](https://github.com/Xtra-Computing/blog/blob/main/CONTRIBUTING.md) for how to submit a post via pull request.

-# Tutorial Intro
+# About Xtra Computing Group
 
-Let's discover **Docusaurus in less than 5 minutes**.
+**Xtra Computing Group** is a research lab at the [National University of Singapore (NUS)](https://www.nus.edu.sg/), School of Computing.
 
-## Getting Started
+We work on **big data management systems**, **parallel and distributed computing**, and **cloud computing**, with a particular interest in emerging hardware (GPUs, FPGAs, etc.) and the intersection of systems and machine learning.
 
-Get started by **creating a new site**.
+## Research Areas
 
-Or **try Docusaurus immediately** with **[docusaurus.new](https://docusaurus.new)**.
+- **Big Data Management Systems** — scalable data processing, query engines, and storage systems built for the cloud and modern hardware.
+- **Parallel & Distributed Systems** — high-performance computing across heterogeneous and distributed environments.
+- **Federated Learning** — privacy-preserving, collaborative ML on non-IID and vertically partitioned data.
+- **LLM Systems & Privacy** — infrastructure and evaluation tools for large language models, including data privacy assessment.
+- **GPU-Accelerated ML** — libraries and frameworks that exploit GPU parallelism for classical and modern ML algorithms.

-## Generate a new site
+## Join Us
 
-Generate a new Docusaurus site using the **classic template**.
+We welcome **undergraduate interns**, **PhD candidates**, and **postdoctoral fellows** to join our collaborative research environment.
 
-The classic template will automatically be added to your project after you run the command:
+Visit [www.xtra.science](https://www.xtra.science) for open positions and contact information.
 
-```bash
-npm init docusaurus@latest my-website classic
-```
+## Links
 
-You can type this command into Command Prompt, Powershell, Terminal, or any other integrated terminal of your code editor.
+- Website: [www.xtra.science](https://www.xtra.science)
+- GitHub: [github.com/Xtra-Computing](https://github.com/Xtra-Computing)
+- HuggingFace: [huggingface.co/Xtra-Computing](https://huggingface.co/Xtra-Computing)
 
-The command also installs all necessary dependencies you need to run Docusaurus.
+## Contribute to This Blog
 
-## Start your site
-
-Run the development server:
-
-```bash
-cd my-website
-npm run start
-```
-
-The `cd` command changes the directory you're working with. In order to work with your newly created Docusaurus site, you'll need to navigate the terminal there.
-
-The `npm run start` command builds your website locally and serves it through a development server, ready for you to view at http://localhost:3000/.
-
-Open `docs/intro.md` (this page) and edit some lines: the site **reloads automatically** and displays your changes.
