I am a final-year PhD student in the School of Operations Research and Information Engineering (ORIE) at Cornell University, advised by Professor Samitha Samaranayake. Before Cornell, I completed my undergraduate studies at Boston College with a B.S. degree in Mathematics.
My research develops network optimization models and mixed-integer programming methods for large-scale systems, with applications to public transit network design, to support decision-making.
