Team


Dr. YunJeong (Eunice) Chang

  • Eunice is a research scientist, a lead educational researcher, and a co-PI for the Lighthouse projects. Chang holds a PH.D. in Learning, Design and Technology from the University of Georgia. Dr. Chang serves as a co-PI of the NSF-funded Lighthouse EC project, focusing on designing diversity-focused CS introductory undergraduate courses. As an instructional scientist and instructional designer, she has led educational research and instructional design for the NSF-funded Lighthouse CC professional development MOOC project and Tapestry workshop. As a co-PI, she has also led Engineering education projects with School of Engineering and Applied Science at University of Virginia. Before joining the Lighthouse team, she was involved in several research projects, including an NSF-funded project, focusing on developing online and blended learning environments for STEM and medical education. Dr. Chang holds a national certificate on interdisciplinary qualitative research. Her research interests include designing learner-centered learning environments with active learning strategies to improve equitable learning and learning engagement in higher education.

Aihua Chen

  • Aihua is the leader of the technical staff for Lighthouse. She provides programming support and assistance for the technical aspects of all Lighthouse projects. In particular, her responsibilities include maintaining the Open edX and Discourse platforms for Lighthouse CC, and assisting with MOOC content development. Aihua has a M.S from Beijing University of Posts and Telecommunications. Before coming to University of Virginia, she was a product designer for Baidu. Aihua is driven by her strong interests in computing education.

Dr. Leslie Cintron

  • Leslie is a research scientist, a lead social science researcher, and a founding member and co-PI for the Lighthouse for Computer Science projects. Cintron holds a Ph.D. in Sociology from Harvard University. Dr. Cintron serves as a co-PI of the NSF-funded Lighthouse EC project, researching how best to increase engagement and diversity in CS introductory undergraduate courses. She is the lead social science researcher and project director for the NSF-funded Lighthouse CC professional development research project and, since 2014, a co-organizer of the Tapestry Workshop. Prior to joining the Lighthouse team, Cintron held faculty positions in sociology at Washington & Lee University, Harvard University and Oxford University (UK). She was a lead researcher on several research projects focusing on workforce and careers. Her research includes a national study of US workers attitudes toward work and family across generational groupings, a study of female high tech entrepreneurs, and research looking at the relationship between student (graduate and undergraduate) attitudes towards work and family and decision-making to pursue further education in computing. Her research interests include equity and diversity in STEM fields and the intersection of work, family and community life.

Dr. Jim Cohoon

  • Along with Joanne McGrath Cohoon, Jim was the co-creator and is now the leader of the Tapestry and Lighthouse projects for increasing Computer Science diversity through faculty education. Tapestry focuses on the engagement of high school computer science educators; Lighthouse focuses on the engagement of college educators – both faculty and teaching assistants. His Chrestomathics project changed several institutions’ introductory college CS1 curriculum using multiple pathways, active collaborative learning, integrated lecture and laboratory, and tailored examples and pedagogies. Locally, the project raised undergraduate women majors from 12% to ~30% and achieved near proportional representation for underrepresented minorities. In recognition of his diversity efforts he was won the IEEE Computer Society’s Taylor L. Booth Educator Award.

Brittany Halsey

  • Brittany is 3rd year at the University of Virginia and an undergraduate research assistant for the Lighthouse CC and EC projects. She is pursuing a B.A. in Cognitive Science concentrating in Computer Science and a M.T. in Elementary Education. Her interests include promoting diversity in computing and making quality education accessible.

Dr. Sarah Hug

  • Sarah has served as a program evaluator on several National Science Foundation grants with emphases on professional development and STEM education. She is a former K12 educator with a doctoral degree in educational psychology, and has experience teaching pre-service and in-service educators. Her professional evaluation and research work includes professional development projects that serve K-12 educators from various disciplines, school counselors, higher education faculty, and professionals serving as outreach volunteers with funding from various national sources. Her education experience in underserved school districts informs her work.

Dr. Luther Tychonievich

  • Luther is co-organizer of the Tapestry professional development workshops for high school computer science educators and an integral member of the Lighthouse project. Since 2009, his participation has been exhaustive: presenting, training workshop organizers, managing applications, and running workshops of various lengths. Besides teaching Computer Science at the University of Virginia, his work interests include larger-scale curriculum redesign and training teaching assistants. In addition he is one of the leaders in the Family History Information Standards Organisation.

Devon Yi

  • Devon is a 3rd year undergraduate at the University of Virginia studying Computer Science. She was a teaching assistant for 2 years to one of UVA's introduction to computer science courses and is currently a research assistant for Lighthouse EC. Her learning interests include student diversity and retention in computer science and the teaching and practice of cyber security.

In memorium

Dr. Joanne Cohoon

  • Joanne was a sociologist who studied the gender imbalance in computing for almost twenty years, and who successfully put these studies into practice with many projects at both the University of Virginia and NCWIT – the National Center for Women and Information Technology. She along with Jim Cohoon were the co-creators and leaders of the Tapestry and Lighthouse projects for increasing Computer Science diversity through faculty education. Tapestry focuses on the engagement of high school computer science educators; Lighthouse focuses on the engagement of college educators – both faculty and teaching assistants. For the Lighthouse CC MOOC, she developed the prototypes of its diversity and active recruiting modules. Joanne’s commitment to excellence and her belief that educator professional development is a force multiplier for change, inspire us daily. She is sorely missed.
