Tongji University

👋 Welcome!

My name is Weida Wang (zh: 王蔚达), and I also go by David. I am a fourth-year undergraduate student at the School of Computer Science and Technology, Tongji University majoring in Software Engineering. As a developer and researcher, my primary interests lie in graph-based machine learning, LLM reasoning and AI for science (AI4Science, currently in chemistry).

Over the past few years, I have gained substantial research experience across various domains. I have worked as a research assistant in the Graph Signal Processing Lab at Tongji University, collaborating with AP. Jin Zeng. My journey also includes research stints at the Intelligent Internet of Things Research Center (IIOT) at Shanghai Jiao Tong University, under the mentorship of Prof. Guanjie Zheng.

If you’d like to connect or discuss potential collaborations, don’t hesitate to drop me an email.

ImagiTale - An Interactive Storybook Learning App for Children

Weida Wang, Leya Yang, Xin Li, Yao Zhang, Yutong Fu, Xinyi Liao

Mobile App CCCC 2023&2024 Award-Winning Work
  • ImagiTale is an AI-driven application designed for children aged 6-8 and their parents. It enhances children’s language expression and cognitive development by providing personalized picture book recommendations and encouraging active storytelling.
  • The app is developed specifically for iPad using Xcode and Swift, with a user interface designed in SwiftUI. It employs SAM for dynamic image segmentation, enhancing visual interactivity. ChatGPT generates engaging dialogues, while Swift Speech handles speech-to-text and text-to-speech conversion. Additionally, a custom emotion analysis model offers tailored feedback to improve children’s language learning through interactive storytelling.
  • This project was submitted to the 2024 China Collegiate Computing Contest - Mobile Application Innovation Contest (CCCC App), where it won the National Third Prize (top 1%) and won the National Second Prize (top 0.4%) and the Best Innovation Award in the 2023 China Collegiate Computing Contest HCL Innovation Competition (CCCC HCI).

CASleuth - the Virus Detective

Tongji-Software Team: Weida Wang*, Shiyi Zhou*, Ziyang Zhang*, Yao Zhang, Yuxuan Wang, Yutong Chen, Yuanyi Lu, Xialu Chen, Xuanyi Liu

Wiki Software Game Video iGEM 2023 Software&AI Track Gold Medal Work
  • The COVID-19 pandemic underscored the need for rapid and accurate virus detection methods, as traditional PCR-based approaches are often time-consuming and require complex laboratory environments. In response, our project focuses on a novel detection method using the CRISPR-Cas system, which offers a more rapid, portable, and cost-effective alternative, particularly suitable for underdeveloped areas. By targeting viral RNA sequences with guide RNAs (gRNAs) designed for specific Cas proteins, this method provides a promising future for scalable and accessible virus detection.
  • To bridge the gap between cutting-edge biotechnology and public understanding, we designed an educational game called CASleuth. This game allows everyday users to learn about CRISPR-Cas technology interactively and engagingly. Alongside the game, we developed a software tool also named CASleuth, tailored for bioinformatics researchers. This tool facilitates efficient database queries and predictions of gRNA efficiencies for different viruses using a deep learning framework based on convolutional neural networks. The web platform serves to promote the project, raising awareness and encouraging adoption among both the scientific community and the general public.
  • The CASleuth project was showcased at the 2024 iGEM competition, where it earned a Gold Medal for its innovative approach in combining education with bioinformatics, enhancing public engagement and advancing virus detection research.
