About Me

I'm a recent M.S. Aeronautics & Astronautics graduate from Stanford University where my research focused on artificial intelligence and autonomous systems. I'm interested in applied machine learning and how it can be leveraged to help us develop and deploy systems capable of intelligent decision-making under uncertainty. I have experience designing intelligent systems using techniques ranging from traditional AI to modern ML (see my experience and portfolio for more). I typically code in Python or Julia, using open-source libraries such as PyTorch, TensorFlow, Scikit-Learn, and Spark.
