Daniel Johnson is a development engineer at the University of California, San Diego division of the California Institute for Telecommunications and Information Technology (Calit2). He manages a design and fabrication lab; his work began with the design and testing of rapid deployment emergency response information technology (IT) infrastructures, including ground and aerial imaging and sensor platforms. Johnson's involvement with "SurgiCam," a tiny surgical camera for minimally invasive surgery (MIS), led to a co-patent on fluidic lens actuation. He is also involved in a start-up company working on a compact cell detection and sorting platform. Johnson works closely with the University of California, San Diego Machine Perception (MP) Lab developing robots for motion research and interactive teaching aids for preschool children. As an investigator for the Center of Interdisciplinary Science for Art, Architecture, and Archaeology (CISA3), he designs and develops tools for the conservation of cultural heritage. He mentors and sponsors students through summer research programs, senior design courses, and the NGS-UCSD collaboration program "Engineers for Exploration." Johnson graduated from University of California, San Diego's Jacobs School of Engineering with a B.S. degree in Mechanical Engineering and is currently pursuing a graduate degree. His research extends his work with CISA3, as he is focusing on 3 axis multispectral imaging techniques.
Vid Petrovic received a B.S. in computer science and engineering and a master's in computer graphics and visualization from the University of California, Irvine. His research focuses on developing a system that visualizes LIDAR data to create three-dimensional replicas of sites that CISA3 is currently working on. Petrovic collects data from a site, renders that data into a visual form on a computer, and then creates an image that can be observed from various angles, light levels, and distances from a separate location. The system that Petrovic is developing allows an objective record of the site to be preserved for future study. Continued research is the cornerstone of CISA3’s mission—to create a future for our past.
David Vanoni was interning at Qualcomm as an undergraduate at the University of California, San Diego, when he first collaborated with Professor Falko Kuester. After he realized the connection between the work he was doing in the computer science department and the applications of the software being developed at CISA3, he decided to continue working with Kuester after graduation. In his first year as a graduate student, Vanoni is focusing on the design of interactive applications for multi-touch surfaces used to visualize, analyze, and annotate different types of data. In the future, Vanoni hopes to be able to work with the LIDAR data and create a multi-touch interface that will allow a viewer to work intuitively with data for research and restoration.
Samantha Stout's interest in analytical methods for materials science stems from her previous research experiences, which focused on nanotechnology applied to medicine. In her current research, she is working on developing methodologies for materials analysis and spectral diagnostic techniques where the "patients" are now artifacts of cultural heritage and can be hundreds of years old. Stout came to the University of California, San Diego, after receiving her B.S. in materials science and engineering from Cornell University in Ithaca, New York. She received her master's in materials science and engineering at the University of California, San Diego, where she is currently working on her Ph.D. When not working on her research, Stout enjoys hiking, cooking, and playing hockey and tennis.
