• Built AI to determine optimal timings of battery cycles and environmental conditions, to prolong their lifetime.------• This AI consistently generates timing profiles with (est.) 4% lower capacity degradation rates than the standard battery test.------• AI developed in Python, using PPO algorithm from stable-baselines3 library• Built robust data processing pipeline (in Python) which delivered key insights on battery models’ performance, via data visualization charts.------• Pipeline used machine learning (Linear Regression model) to forecast batteries’ expected lifetimes with 96% accuracy.------• Insights from pipeline are being used by Power Sources Group to characterize aging rates of various battery models.• Built webpages (in Python Django framework) for battery test data website, enabling users to upload, query, or delete battery test data records from SQL database. Webpages are projected to be used by ~50 staff.

• Project 2: Managed team (6 students) in development of Reinforcement-Learning AI to control simulated racing vehicle (in Python, using PPO algorithm from stable-baselines3 library). AI can autonomously drive racecar through various racetracks with low lap time.------• Currently refining simulation code so that AI can be utilized to control lab’s real-world autonomous vehicle• Project 1: Managed team (4 students) in development of adaptive cruise control system (in Matlab and Simulink). System consisted three integrated PID controllers. Presented project poster at URSCA Research Conference 2023.• Project 1: Built various Graph Machine Learning models (in C++, MATLAB) from scratch, in order to forecast traffic flow on LA streets (accuracy achieved: 91%). Key models used: Graph Temporal Neural Network, Graph Attention Network, LSTM
