Data Analysis and Classification of Animals in Complex Settings
- Implemented DeepLabCut pipeline to automate mice tracking in behavioral videos, reducing processing time from weeks to 3 days, and demonstrated core technical skills, including Python, DeepLabCut, YOLO, and vectorization
- Developed data labeling and verification system to improve the training of data set quality for computer vision models
- Optimized MLE, XGBoost, Transformer, and MoE models for behavior classification, achieving better accuracy through hyperparameter tuning
- Created YOLO-based cockroach tracking system using newly annotated datasets, significantly improving the detection reliability
- Designed unsupervised learning pipeline (t-SNE/UMAP) to identify novel mouse hunting strategies
- Built data visualization tools, including interactive website for conference presentations (NEXTEN 2024) and presented at NEXTEN 2024
- Verified findings with various statistical methods (including LMM, ANOVA, Tukey HSD)
- Assisted in neural recordings analysis for Alzheimer's research using DCC, d2, and dβ metrics of the Brain Criticality Hypothesis to predict disease
- Contributed to the development and optimization of d2 Python algorithm and correction of existing d2 algorithm in untested edge cases
- Designed dβ Python algorithm, benchmarked, and found a sanity test method for dβ algorithms
- Conducted surgical preparations including tetrode construction and animal monitoring
- Improved hardware and software design for mice sleep-deprivation experiment which was previously constantly causing experimental failures and hardware failures of experimental devices
- Conducted mice's roach hunting experiments, including mice handling pre- and post- experiment
- Currently leading animal hunting behavior manuscript preparation for the expected preprint publication in November 2025

Surgery and Neuron Activity Recordings
- Designed experiment procedure, hypothesis, gained outputs, and evaluations based on the measurements.
- Performed mouse tracheostomy and cochlear electrode implantation surgery, successfully recording auditory neural activity in anesthesia management along with team members
- Isolated bullfrog sciatic nerve through precise dissection, including decapitation, skinning, and tissue removal to prepare for electrophysiological measurement
- Conducted crayfish tail ablation and recorded neuromuscular activity, analyzing the resultant electrophysiological data
- Compiled surgical data into waveform graphs and co-authored three detailed manuscripts analyzing experimental findings and potential research directions
- Developed advanced surgical abilities and academic writing skills through repeated operations and literature-based investigation
