Three RailTEC scholars successfully completed, defended, and deposited their Ph.D.’s this semester. Congratulations to Dr. C. Tyler Dick, Dr. J. Riley Edwards and Dr. Chen-Yu Lin. All three were advised by Professor and George Krambles Faculty Fellow Dr. Christopher Barkan. Dr. Edwards’ dissertation title was: Quantification of Prestressed Concrete Railway Crosstie Flexural Response: Implications for Mechanistic Design, Dr. Dick’s was: Influence of Traffic Complexity and Schedule Flexibility on Railway Classification Yard Capacity and Mainline Performance and Dr. Lin’s was: Probabilistic Risk Assessment of Railroad Train Adjacent Track Accidents. This is not the first hat trick for Professor Barkan. In a three month period two years ago, he shepherded another set of three RailTEC students to successful completions of their Ph.D.’s.
