New to Berkeley Lab Computing Sciences Team
July 31, 2012
Cy Chan, Computer Science Postdoctoral Fellow
As a new postdoctoral fellow in the Computational Research Division's (CRD's) Computer & Data Sciences Group, Cy Chan will be working on algorithmic optimizations research for multiphysics fluids codes, specifically, codes targeted at efficient combustion and renewable resources.
Though Chan may be new to the C&DS group, he is no stranger to the Berkeley Lab. In fact, he was an intern at the lab two summers in a row—in 2008 and 2009. As an intern, Chan developed an auto-tuning software code generator for stencil-based partial differential equation solvers on multi-core systems. The code generator produces both C and CUDA code (for NVIDIA graphics hardware) from general Fortran stencil loops.
Chan was also co-author of the paper, A Generalized Framework for Auto-tuning Stencil Computations, which was honored with a Best Paper Award at the 2009 Cray User Group Conference in Atlanta, Ga. Other researchers on the award-winning paper include: Shoaib Kamil, Samuel Williams, Lenny Oliker, John Shalf, Mark Howison, E. Wes Bethel and Prabhat.
A native of Houston, Texas, Chan moved to Boston, Mass to pursue an undergraduate degree in applied mathematics and computer science at Harvard University. He then worked for years at the Massachusetts Institute of Technology's (MIT's) Lincoln Laboratory doing signal-processing research (digital nonlinear equalization), which inspired him to pursue his doctorate in computer science at MIT.
In his spare time, Chan enjoys cycling, solving puzzles and traveling with his wife. Now that he is a Californian, he also plans on learning to camp and rock climb.
Yingjie Lin, Biological Data Management & Technology Group
As the new user interface software engineer in the CRD's Biological Data Management & Technology Group, Yingjie Lin will help manage the Integrated Microbial Genomes (IMG) databases and add new features to the IMG systems.
Before coming to Berkeley Lab, Lin was a graduate student at New York's Mount Sinai School of Medicine. For her Ph.D. thesis, Lin built and maintained two web applications for identifying and characterizing ligand binding sites in protein structures.
"As I saw that my web applications can help many researchers in different countries, I was so happy and therefore decided to focus on developing web-based tools to facilitate biological research," says Lin.
A native of Xiamen, China, Lin moved to Beijing to study Biological Sciences at Peking University. Shortly after, she moved to New York to study biomedical sciences at Mount Sinai School of Medicine. In her free time, Lin enjoys roller skating, hiking, cooking and watching movies.
Matthew Emmett, Center for Computational Sciences & Engineering
As the newest postdoctoral researcher in CRD's Center for Computational Sciences and Engineering, Matthew Emmett will be working on advection-diffusion-reaction equations. More specifically, he will be incorporating defect and deferred correction schemes into various existing and upcoming projects at CCSE.
A native of Calgary, Canada, Emmett earned an undergraduate degree in mathematical-physics from Simon Frasier University in British Columbia. After college, he worked and volunteered as a developer and systems administrators at various companies and cooperatives before returning to school to pursue a doctorate in Applied Mathematics. He received a doctorate from the University of Alberta in 2010, and has spent the last two years working with Professor Michael Minion in the Applied Mathematics Department of the University of North Carolina, Chapel Hill.
"I became interested in computing during my middle school years, largely due to the friends that I had back then, and still have today," says Emmett. "We had a lot of fun programming small games and this translated in having fun programming numerical schemes for differential equations in our math and physics classes during our undergrads."
After two years in North Carolina, Emmett says he misses the cold Canadian winters. Though he will be telecommuting from North Carolina until January 2013, and hasn't spent much time in the Bay Area yet, he anticipates enjoying the diversity and climate of Northern California. In his free time, Emmett enjoys spending time with his family, making beer, biking, hiking, canoeing and skiing.
