Dr. Rebecca Parsons is Thoughtworks' CTO Emerita. She has more years of experience than she’d like to admit in technology and large-scale software development. She recently co-authored the book Building Evolutionary Architectures with colleagues Neal Ford and Pat Kua.

Before Thoughtworks she worked as an Assistant Professor of Computer Science at the University of Central Florida, after completing a Director's Post Doctoral Fellowship at the Los Alamos National Laboratory. Her interests include parallel and distributed computation, programming languages, domain specific languages, evolutionary architecture, genetic algorithms, and computational science.

Rebecca received a BS in Computer Science and Economics from Bradley University, and both an MS and Ph.D. in Computer Science from Rice University.
