(2/14/2004. I and Anastasia. She was not very happy because I grabbed her from the playground for taking this picture. Seen in the background is the Woodriver Elememtary School, Fairbanks, AK, where she will be attending in the fall of 2008.)

Cheng fu obtained his B.S. and M.S. degrees in Mechanical Engineering from the National Taiwan University and his Ph.D. degree in Mechanical Engineering from the University of Wisconsin, Madison in 2000. Dr. Chen's research, since he joined the UAF at the end of 2002, has been on the reliability of electronic packaging and the development of miniaturized microfluidic devices for microdialysis.
In the electronic packaging reliability project, Cheng-fu has been focusing on the influence of underfill filler settling on the lifetime of solder interconnects as well as on the distribution of the die/underfill interfacial stresses that have direct impact on die delamination/cracking. Currently he is working on the effects of acceleration and mechanical shock on electronic systems, particularly, 3D stacked chips. The research is aimed at improving the reliability of stacked Chip Scale Packaging (CSP) modules for commercial as well as space and military applications.
In the microfluidics project Cheng-fu has been working on the miniaturization of microdialysis in the past few years with Dr. Kelly Drew of IAB, a sampling technique to access to the extracellular space in tissues to sample molecular particles. Of some successful milestones he achieved include one pending patent.
