Highlighted an exciting opportunity for future bionic composite materials by tailoring interactions between living organisms and 3D-printed synthetic materials. • Bone-inspired Healing of 3D-Printed Ceramics Conducted experiments on autonomous healing of 3D-printed porous polymer-derived ceramics with carbonate-precipitating bacteria; Observed good mechanical behavior as well as thermal and chemical resistance on the healed interfaces of ceramics; Performed a theoretical study to understand his healing mechanism. • Study on Mechanical Behaviors of Electrophoresis induced Hydrogel Adhesion Project Sponsored by Air Force Office of Scientific Research Young Investigator Program Established an analytical theory framework to model the electrophoresis-induced reversible adhesion; Obtained good agreements between the theoretical results and the experimental results for both electrophoresis-induced hydrogel adhesion and adhesion releasing. • Study on Extracellular Matrix of Pancreatic Tissue Modeled 3D elastomeric structures using Nonlinear Finite Element Analysis (FEA) to study the bio-mechanical response and buckling behavior of the resected pancreatic tissues (soft materials). ### Graduate Student @ University of Southern California Jan 2020 – Jan 2021 | Los Angeles, California, United States • Identification Hotel Reviews Based on Naïve Bayes and Perceptron Classifiers Implemented a Naïve Bayes classifier and perception classifiers (including vanilla and averaged) to identify hotel reviews as either truthful or deceptive, and either positive or negative. • Part-of-speech Tagger for Different Languages based on a Hidden Markov Model Constructed a part-of-speech tagger based on HMM to add tags for Italian, Japanese, and an unknown language. • Chinese Bert-based Task Oriented Dialogue System Built a Bert-based task-oriented dialogue system, which is a dialogue assistant for flight and restaurant reservation in Chinese. Fine-tuned the intent classification and slot filling with Bert-pretrained language model with PyTorch. • AI Searching Agent for “Time Travelling” Problem Developed an AI agent to search for the optimal and shortest path and navigate through a complex time-travelling configuration. The problem was solved with: BFS, UCS, and A* search. • AI Agent for Little-go Gaming Developed an AI agent to play a small version of the Go game, a reduced board size of Go game, based on no-suicide and KO rules. Both game playing and reinforcement learning algorithms were tried to improve the winning percentage. • Hand-written Digits Classifier based on a Multi-layer Perceptron Neural Network Constructed a multi-layer perceptron (MLP) neural network and used it to classify hand-written digit with no existing machine learning libraries. • Stock-searching Web and Mobile Applications Implemented the backend using Python Flask deployed on GCP. Developed a stock-searching web application and a mobile application on iOS system. • Grain Tracking based on Highly Parallel DBSCAN Simulated the sintering processes of aluminum nitride nano powders based on parallel molecular dynamics. The output data is further analyzed using a parallel DBSCAN technique. ### Teaching Assistant @ University of Southern California Jan 2020 – Jan 2020 | Los Angeles, California, United States Teaching Assistant for Finite Element Analysis (Graduate Course) and Mechanics of Deformable Bodies (Undergraduate Course); held the lab class and discussion session independently; supervised students with their homework problems. ### Research Assistant @ 北京航空航天大学 Jan 2014 – Jan 2017 | Beijing City, China • Study of Fastener Effect on Composite (CFRP) Bolted Joints Built a progressive damage models based on FEA with ABAQUS/UMAT to investigate the mechanical behaviors (especially secondary bending and failure mode effectiveness) in bolted composite joints. • Key Techniques of Composite Structure Design and Analysis Project Sponsored by Commercial Aircraft Corporation of China, Ltd. (COMAC) Summarized Fatigue Characteristics Analysis and Test Methods in Metal/Composite Hybrid Joints; Conducted static and fatigue tests on metal/composite hybrid joints and structures through Instron based on ASTM. ## Education ### Doctor of Philosophy - PhD in Civil Engineering University of Southern California Jan 2017 – Jan 2022 ### Master's degree in Computer Science University of Southern California Jan 2020 – Jan 2021 ### Master's degree in Aerospace, Aeronautical and Astronautical/Space Engineering Beihang University Jan 2014 – Jan 2017 ### Bachelor's degree in Aerospace, Aeronautical and Astronautical Engineering Beihang University Jan 2010 – Jan 2014 ## Contact & Social - LinkedIn: https://linkedin.com/in/an-xin-450006178 - Website: https://scholar.google.com/citations?user=gmKjLncAAAAJ&hl=en - Website: https://sites.google.com/view/an-xin10182020/about-me - GitHub: https://github.com/docdogtor --- Source: https://flows.cv/anxin JSON Resume: https://flows.cv/anxin/resume.json Last updated: 2026-03-22
