First lecture, discussion — “Optimizing Access Delays to Enable Integrated Outpatient Care” by David Lynn Kaufman ’98, Ann Arbor, Michigan.

Kaufman is an assistant professor in the College of Business at the University of Michigan-Dearborn. He previously taught operations research and financial engineering for the university in Ann Arbor. Kaufman’s expertise lies in decision-making under conditions of uncertainty and risk management. His experience includes product development for RiskMetrics Group, a financial risk management company whose clients have included the 10 largest investment banks, 69 of the 100 largest investment managers, 42 of the 50 largest mutual funds and 16 central banks. Kaufman also advises students pursuing MBA, Master of Engineering and Master of Supply Chain Management degrees through the Tauber Institute for Global Operations. He has advised teams at top global firms, including Amazon, Boeing, Borg Warner, Microsoft, SRG Global and W.W. Grainger.

Kaufman holds a B.A. in mathematics and physics from Bethel and a Ph.D. in industrial and operations engineering from the University of Michigan.

2–2:55 p.m.

Second lecture, discussion — “From Carbon Black to VOC Suppressants: The Role of Particle Formation in Achieving a Safer, Greener Tomorrow” by Chad Unrau ’04, Houston, Texas.

Unrau is director of engineering for NanoVapor Inc., a pre-revenue company in Houston, and is responsible for customer implementation and optimization of NanoVapor’s breakthrough vapor suppression technology, which reduces the evaporation of volatile organic compounds. His role also encompasses development of next generation technologies. Prior to joining NanoVapor, Unrau was a senior research and development engineer for Cabot Corporation, primarily responsible for developing and implementing an industry benchmark technology to improve the efficiency of the carbon black production process.

Unrau holds B.A. degrees in mathematics and physics from Bethel, and M.S. and Ph.D. degrees in both mechanical and chemical engineering from Washington University in St. Louis.

Keynote lecture, discussion — “The Trouble with Numbering Things: SIMD Computation in a Bi-Endian World” by Bill Schmidt ’82, Rochester, Minnesota.

Schmidt is a senior software engineer with International Business Machines Corporation, where he has spent the last 23 years developing optimizing compilers. That is, he tries to make poorly written software run efficiently on recalcitrant hardware. He currently works on both the GCC and LLVM open source compilers, improving them for use on IBM’s POWER architecture.

Schmidt holds a B.A. in mathematics and music from Bethel, and M.S. and Ph.D. degrees from Iowa State University. He has 50 issued U.S. patents, primarily in the field of compiler optimization.
