Buildings 32 and 42 are expected to remain closed through Nov. 10. This date is our current estimate and is subject to change pending ongoing evaluations and the safe restoration of the affected electrical systems.
The continued closure of Buildings 32 and 42 will affect School of Engineering and Applied Sciences (SEAS) operations as well as the operations of the Art, Digital Media and Chemistry programs. This includes in-person instruction and certain campus activities housed within those facilities. Emergency Remote Instruction (ERI) will remain in effect for impacted courses.
Visit the Campus Alerts page for more information.
For safety concerns, contact OPSEM at 202-274-5050. For emergencies, call 911.
From 2019-2022, CAM-STAR has been working on the following three main projects, focusing on devices and tools enabled by advanced manufacturing (AM) for space technology and applied research. All three projects are interconnected by complementary niche areas.
Faculty Team: Jiajun Xu (UDC), Pawan Tyagi (UDC), Angel Alvarez-Hernandez (JSC), Mike Ellis (ACT), Calin Tarau (ACT), Bao Yang (UMD)
UDC team led by Dr. Xu and external collaborators (including Advanced Cooling Technologies, University of Maryland and NASA Johnson Space Center) have been working collaboratively.

UDC team led by Dr. Tyagi and external collaborators (including Advanced Cooling Technologies, University of Maryland and NASA Johnson Space Center) have been working on the task 1 in which methods to process the surface finishing of AM produced parts is being developed.
Faculty Team: Lei Wang (UDC), Qiushi Chen (Clemson), Jiajun Xu (UDC), Kamlesh Lulla (JSC)
UDC team led by Dr. Wang and external collaborators at Clemson University have been working on the task 1, in which they are working on how to formulate a bio-inspired energy-efficient drilling method and develop a discrete element model for evaluating the mechanism for interaction of drilling tool and the lunar regolith (granular materials). The technical lead has engaged three UDC students to work on this project.
