Highlighting our past employees and students' current work in their respective industries. 

Emily Khalid

Emily Khalid

While at the lab, Emily worked on taking a baseline representation of the Cognitive Empowerment Center (EP6) in Revit and iterated it as close to reality as possible by adding materials, furniture, and lighting. This model was used to create a walk-through video that illustrated the Empowerment Center experience prior to its construction completion and was shown to all collaborators of the EP6. It served as a foundation for research in the lab, including space syntax, wayfinding, and the building's Post Occupancy Evaluation (POE).

Additionally, Emily was a part of POE team at the lab, where she researched, planned, and executed different POE methods in order to evaluate the EP6 building once occupied. The long-term POE plan she and her teammates developed will measure a set of metrics and goals evaluating whether the EP6 building is performing to the best of its ability while also championing its users.

After graduating with her M.Arch, Emily is studying for her six Architecture Registration Exams in order to become a licensed Architect. She hopes to continue working in the Healthcare architecture sector while pursuing human-centered design that gives back to the community.

Bushra Obeidat

Bushra Obeidat

Bushra Obeidat is an assistant professor at Jordan University of Science and Technology. She holds a Ph.D. and MA in architecture from the University of Kansas (2017), an MSc in Health and Design from Georgia Institute of Technology (2018), and an MSc in Architecture from Jordan University of Science and Technology (2009). Her passion for healthcare design and research has been a significant springboard for her long-term research goals of expanding my field of study.

Bushra joined the SimTigrate Design Lab in 2017 to learn, experience more, and open up new research horizons for herself in the field of healthcare design. She wanted to work directly with Dr. Craig Zimring and learn from his research experiences. During her time at SimTigrate, she worked on the team-based design for primary care, in a collaboration with the Mayo Clinic Community Practice. She has found inspiration from working on this project since it links the built environment and human behavior. She applied an evidence-based design approach for designing and assessing healthcare environments as well as use of spatial and configurational analysis.

For Bushra’s future career, she would like to work more in healthcare design in the Middle East regions. It will always be an important part of her life to help people in Jordan and improve the healthcare system in the Middle East. Her primary goal as an educator is to help students develop their own critical and creative design-thinking, realizing their role as designers and the impact of their designs on users.

Yousef Bushehri

Yousef Bushehri

Yousef Bushehri is a Ph.D. student in evidence-based design investigating how the design of spaces affect human health. His research interest brings together spatial design, human aging, and designing for aging. In addition Yousef is interested in methods of analyzing and quantifying spatial experience so that designs can be compared to extract characteristics to inform future guidelines. During his time at SimTigrate, Yousef worked on a project at the Aflac Pediatric Cancer Center where a novel passport tool was developed and the kids were part of the research team to improve their experience and understand bottlenecks in the care process. He also worked on furthering the development of the Functional Scenarios method of examining environments by examining NICUs.

His professional history includes practicing as an architect in Kuwait, participating as an artist in residence at Google's Paris office, and working as a research assistant at the SimTigrate Design Lab. Besides his studies and research, Yousef is currently teaching architectural design studios at Georgia Tech, directs the Precollege Summer Studio at the College of Design, and is the exhibition organizer and founding member of the ConCave Ph.D student group of the College of Design.

Yousef attended The Catholic University of America in Washington, D.C. where he earned his BS.Arch (2011) minoring in psychology, and his M.Arch (2013) focusing on digital media, and he earned his MS.Arch (2016) at Georgia Tech with a concentration in healthcare design.

Lisa Lim

Lisa Lim

Lisa Lim, PhD, is a researcher, designer, and educator at Texas Tech University with the primary focus of improving health and wellness of users through design. She received her Bachelor of Architecture and Master of Science in Architecture from Seoul National University, and her Ph.D. from Georgia Institute of Technology. Dr. Lim is interested in how spatial layouts can support individual experience and organizational outcomes and how designers can provide such environments. With her academic and practical architectural background, she has expertise on analytical and empirical approaches for understanding both space and the people in it.

Projects that she has worked on:

• Supporting New Models of Team-Based Primary Care: Developing and Testing Measures for the Impact of the Built Environment

• Patient Centered Medical Home Clinic Analysis for The US Defense Health Agency • Increasing Retention in Care Through Better Clinic Environment [Related news]

• Developing a Methodology for Evaluating Neonatal Intensive Care Unit Design

Zorana Matic headshot

Zorana Matić

Zorana Matić, Ph.D., is a researcher and educator trained as a designer. Her research focuses on the links between the built environment, health, well-being, and sustainability. She examines the impacts of our built environments on behavioral choices and health outcomes at different scales, leveraging her expertise in spatial and ergonomic analysis. For her dissertation ("Gentrification or Health-Promoting Resource? Long-Term Residents' Perceptions and Use of the Atlanta Beltline"), she examined the relationships between regreening interventions, gentrification, and long-term residents' health.

In 2016, she joined the SimTigrate Design Lab, where she was deeply engaged in healthcare design research and the field of evidence-based design. By integrating evidence, mock-up simulation, observation, rapid prototyping, and co-design with the end-users, she aims to develop design solutions that support improved user experience, better communication and teamwork, efficiency, and automate safer behavior. For her research on the impact of environmental design on safe doffing of personal protective equipment (PPE) after providing care to Ebola patients, she was awarded the 2020 Researcher of the Year Award (Healthcare Design Magazine).

Zorana gained extensive teaching experience working with both architecture and urban design studios. She holds a Bachelor of Architecture and Master of Architecture and Urbanism from the University of Belgrade, Serbia. She is the recipient of several awards in design competitions and has been awarded several fellowships, including the 2018 EarthShare Fellowship (Architecture Foundation of Georgia AFGA), 2013 School of Architecture Ph.D. fellowship, 2008 Eurobank EFG Scholarship for the best 100 students in Serbia, and Scholarship of the Republic Fund for Scientific and Artistic Youth of Serbia (2007-2012).
