A.J. Medford

Associate Professor

Education: B.S. Textile Engineering (NC State University); Fulbright Fellow (Technical University of Denmark); Ph.D. Chemical Engineering (Stanford University)

AJ Medford is an Associate Professor in the School of Chemical & Biomolecular Engineering. His research focuses on the intersection of data science, electronic structure theory, and catalysis science, with contributions including machine-learned exchange correlation functionals for density functional theory, application of neural networks to fit transient kinetic datasets, and establishing mechanistic insight into nitrogen conversion reactions, and was the recipient of the 2023 ACS "Early Career in Catalysis" award. He developed the course "Data Analytics for Chemical Engineers", which is now one of the core courses in the "Data Science for the Chemical Industry" certificate program and has won several teaching awards including the Georgia Tech "Junior Faculty Teaching Excellence" and "Excellence in Online Teaching" awards. Outside of research and teaching, he enjoys spending time with his wife and two daughters and outdoor activities.

Big Data & Quantum Mechanics VIP Team

The Big Data & Quantum Mechanics team is a "vertically integrated project" (VIP) consisting of 15–20 undergraduate students ranging from sophomores to seniors from diverse disciplines including computer science, chemical engineering, electrical engineering, and materials science. The VIP team members are an important part of the Medford research group, but membership changes often, so specific members are only listed by request.

To learn more about the VIP course, you can look at the course materials. To join, you should apply for a permit through the Georgia Tech VIP program. Spots fill up fast, so please submit a permit as early as possible if you would like to join.
