Thomas K. (Tom) Holley

Dr. Thomas K. (Tom) Holley is the Director of the Petroleum Engineering Program at the University of Houston. 

I am very proud of my University of Wisconsin Physics Department heritage. I joined Shell Oil Company in 1982 directly following a Ph.D. with Professor Chun Lin of UW Physics on ab initio calculations of electron scattering cross-sections on diatomic molecules.

Although I had no prior education or experience in geology, geophysics, or the oil business prior to joining Shell, over the next 28 years I held Shell positions that span much of exploration geophysics, including seismic data processing (statics, seismic imaging), quantitative interpretation of fluids in porous media, seismic data interpretation, training (Geophysics Training Coordinator for the U.S.), and research (3-D seismic survey experimental design, theoretical and experimental studies of elastic P-wave and S-wave anisotropy, seismic imaging including a patent involving imaging and survey design).
One of the treats in my Shell career was to serve as Ph.D. recruiter at UW Madison.  We were able to recruit some of the current outstanding technical leaders in Shell R&D from the UW Physics Department and Electrical Engineering.  Shell was also generous with the Physics Department during my tenure, for which I am most grateful.

My final Shell assignment was to lead a team of about 40 geoscientists and computer scientists in our two exploration and production laboratories in Houston and Rijswijk, The Netherlands (a suburb of The Hague). That team still produces Shell’s proprietary seismic data interpretation and modeling system called 123DI. 123DI is one of the two main software systems that Shell uses to put geophysics and geology research results into the hands of Shell geoscientists, with a growing community of about 2000 users worldwide in 23 countries at the time of my retirement.

In early 2010 I retired early from Shell specifically to assume the position of Director of Petroleum Engineering for the University of Houston, fulfilling a life-long dream of returning to university life. We are building a new Petroleum Engineering Department almost from the ground up, including new curricula, new faculty, new facilities, the works. The undergraduate program has grown from about 20 students when I arrived to more than 450 today, with about 85 graduate students as well.  I am a bit overwhelmed by the magnitude of the challenge, but I am confident that my UW training will once again stand me in good stead. 

I owe a great debt that I can never fully repay to Chun Lin, Sunggi Chung, and many others in UW Physics past and present.  I hope to mimic their contributions to the Department by my own service on the UW Physics Board of Visitors.

Greg Jaczko

Robert (Bob) K. Leach

Dr. Robert (Bob) K. Leach completed his Ph.D. in low temperature physics in 1972 under the direction of Professors Paul Moran and William Fitzsimmons.  The experiment employed electron spin resonance to detect metastable hydrogen atoms produced in solid hydrogen by electron bombardment.  After this low temperature work Bob moved to a post-doctoral project at UW Space Physics under the direction of Professor Frank Scherb.  The UW team built sounding rocket experiments with on board 100kV accelerators to study charged particles in auroral events.  Bob with UW Physics alumni Dr. John Lynch traveled to Fairbanks Alaska to launch these payloads.  This field test experience led to interesting industrial jobs running test programs and directing instrumentation laboratories.

For the past thirty years Bob has held industrial jobs in the Minneapolis area.  At Honeywell and Alliant Techsystems he managed special instrumentation groups, lead product verification programs, and provided staff engineering support for test laboratories.  During that period UW Physics associations have resulted in successful projects at work.

At Honeywell UW Physics alumni Dr. Fred Williamson and Bob were struggling with implementing an optical aim-point positioning system that would work in daylight.  Fred posed the problem to UW Space Physics Professor Dan McCammon.  Dan proposed a solution exploiting atmospheric absorption properties with low power lamps to mark the object.  Fred and Bob developed a system based on Dan’s insight.  System performance was very good and resulted in a Honeywell technical achievement award for this effort.
For the past eleven years Bob has worked for Science Applications International Corp (SAIC).  Assignments there have enabled him to visit interesting test facilities.  His favorite is San Nicolas Island, CA- a Navy test facility and protected wildlife refuge.  Starting around February over 40,000 sea lions haul out on the beaches and make such a racket you can easily hear them five miles inland.  The islands’ wildlife is so interesting that getting stuck there due to test delays is a nice break from work.

Greg Piefer

Dr. Greg Piefer is the founder of SHINE Medical Technologies and presently serves as its CEO. Before this, he served as the president of Phoenix Nuclear Labs, where he managed the development of high-output neutron sources and high voltage power systems.  He formerly served as the Chief Technical Officer to Gillware Inc., a leading data recovery and backup company.
