Christopher A. Brown, PhD, PE, lab founder and director, has been a member of the WPI faculty since 1989. In 1983 he completed his doctoral work on machining at the University of Vermont. He spent four years in the Materials Department at the Swiss Federal Institute of Technology, studying machined surfaces and directing the mechanical surface treatment group. Then for two years he was senior research engineer, working on product and process development, responsible for coatings, microscopy and the machine shop at Atlas Copco's European research center. Chris has over a hundred articles and presentations on surfaces and surface metrology. He has a patent on a fractal method for characterizing surface textures, develops software for surface texture analysis and teaches courses on surface metrology, manufacturing processes and design. Chris participates in national and international research and engineering conferences, is a corresponding member of the CIRP and has been active in surfaces committee since 1990. In addition, he works on national standards on surfaces texture (ASME B46).

Sarah Jordan

M.S. Materials Science and Engineering, Ohio State University, March 2004
B.S. Metallurgical Engineering, Ohio State University, December 1999

Sarah Jordan currently works at Timken-Research. She originally worked in the failure analysis lab. Now she works at the Prototype facility in the Heat Treat department improving carburizing, hardening, and induction heating processes. She worked in the Surface Metrology Lab from 2004 to 2005 studying ground polyethylene ski bases and other materials. She received her MS from Ohio State University where her thesis entailed thermo-mechanical modeling of the thin slab casting process. In addition she has been involved with tribology research at Battelle and AFM studies of titania thin films at Arizona State University. She also has manufacturing experience from working in steel mills and foundries.

John Kummailil

Ph.D. Manufacturing Engineering, Worcester Polytechnic Institute, Worcester. 2004
M.S. Engineering, Plastics Engineering, University of Massachusetts, Lowell. 1996
Honours Diploma in Systems Management, NIIT, New Delhi. 1993
B.Tech. Rubber Technology, Madras Institute of Technology, Chennai. 1992
B.Sc. Chemistry, Loyola College, Chennai. 1989

John currently works for Boston Scientific Corporation, Inc., where he manages the Imaging Systems Group, implementing real time imaging algorithms used in minimally invasive medical devices. Before obtaining his Ph.D., he worked for Molecular Geodesics, Inc. (MGI), a DARPA-funded biomedical startup, to run their Rapid Manufacturing Center. At MGI, he leveraged his expertise in Rapid Prototyping as Principal Investigator on a NASA-funded project "Functionally Adapted Biomaterials for Space Exploration" to fabricate nature-inspired geometries in metal using Laser Engineered Net Shaping (LENS) and served on the Rapid Prototyping Panel at the National Manufacturing Week Conference. He left Molecular Geodesics when the company closed in 2001, and continues to explore his interests in Rapid Manufacturing as a Ph.D. candidate at WPI.
