Dr. Julian Yarkony PhD
Greetings, I am Dr. Julian Yarkony. I finished a PhD in computer science at the University of California Irvine in July 2012 where I studied under Dr. Charless Fowlkes and collaborated heavily with Dr. Alexander Ihler. I completed post-docs with B.S. Manjunath and Fred Hamprecht at University of California Santa Barbara/University of Heidelberg respectively. My research concerns the development, application and improvement of column generation and integer linear programming techniques techniques. A particular focus of mine has been on the development of new methods of dual stabilization in the context of column generation. I apply these approaches to standard logistics applications of column generation and to non-standard applications such as those in computer vision, machine learning, biology, and robotics. My Erdos number is 3.
