He brings to his current position a wealth of experience as a former Program Officer at the National Science Foundation (NSF). At NSF he was responsible for $30 million annually of investments targeted on improving computing and STEM education. In that role Dr. Bobb worked at the highest levels of the federal government to help shape the national research agenda for effective means of delivering equitable and quality computational education to all students. He has worked with members of the Office and Science and Technology Policy in the Obama Administration to set the national strategy for STEM education at both post-secondary and secondary school levels. He was selected as a member of President Obama’s My Brother’s Keeper STEM + Entrepreneurship Taskforce to help U.S. cities craft strategies to engage young men and boys of color in the STEM landscape. Prior to his federal appointment, Dr. Bobb was the Director of the STEM Initiative for the University System of Georgia, a collaborative effort with the governor’s office to improve STEM education across the 30 public institutions serving approximately 325,000 students in the state. Dr. Bobb brings to STEM education a fierce commitment to equity as an indicator of justice. He has addressed and advised numerous leading tech sector companies, universities and k-12 schools. His writing on STEM education and culture has been featured in The Atlantic, Black Enterprise, The Root, Edutopia and on the Obama White House Blog. His national and state leadership have contributed to a STEM education agenda that is more honest and reflective of contemporary social and cultural realities.

Director of Educational Innovation and Leadership

Lien Diaz is a founding partner of the Constellations Center for Equity in Computing at Georgia Tech. Bringing an essential core foundation of equity in access and opportunity to computer science education, her role as Director of Educational Innovation and Leadership will help establish the Constellations Center as a leader in expanding computer science education through an equitable and comprehensive approach in national/international, state, and local education systems.

Her professional experiences span over twenty years focusing on STEM and CS education. She was a Principal Investigator of a Broadening Participation in Computer Science Collaborative Research grant funded by the National Science Foundation to develop the new Advanced Placement Computer Science Principles course resulting in over 50K students enrolling in the course in its inception and making it the largest course launch in the history of the AP Program. Lien is a former classroom teacher (6-12 mathematics and science) implementing cutting edge curricula and pedagogy to engage students in high quality learning experiences in the classroom. Lien has worked with the Urban Systemic Program and the Mathematics and Science Partnership as a mentor and staff developer where she developed and facilitated professional development, both classroom-based and at scale with teachers, administrators, and local and state education leaders, and raised achievement levels in low resource schools.

As a CS and STEM ed crusader, Lien’s work is motivated by challenging the status quo to change perspectives of CS education and make transparent the educational issues that must be addressed to obtain equity in school systems across the country. She formed a cadre of secondary and post-secondary educators to integrate instructional practices in national professional development efforts that ensure higher levels of engagement and success in CS classrooms. Lien firmly believes that equity must be at the heart of collaborative efforts to overcome socio-economic barriers and issues of race, gender and identity that persist in education.

Lien obtained a B.S. in Interdisciplinary Studies from the University of Texas at El Paso and an M. Ed. in Mathematics from Texas State University. She lives in the Atlanta metropolitan area with her husband, Leroy, and is a mother of four children, Justice Adonis, Adelina Liberty, Alana Freedom, and Aleah America.

Charles Isbell Headshot
Executive Director

Dr. Isbell's research passion is artificial intelligence. In particular, he focuses on applying statistical machine learning to building autonomous agents that must live and interact with large numbers of other intelligent agents, some of whom may be human. Lately, Dr. Isbell has turned his energies toward adaptive modeling, especially activity discovery (as distinct from activity recognition); scalable coordination; and development environments that support the rapid prototyping of adaptive agents. As a result, he has begun developing adaptive programming languages, worrying about issues of software engineering, and trying to understand what it means to bring machine learning tools to non-expert authors, designers, and developers.
