Brief Bio:
Steve has 27 years experience as a practicing civil engineer.  His primary fields of civil engineering practice are geotechnical engineering (25 years experience), site engineering (27 years), and various types of structural engineering design (20 years).  

With regards to Steve's credentials as a scholar, he is the editor of one book, and the author/co-author of eight book chapters.  He has been the primary author or co-author of twenty peer reviewed journal articles the latest one published in January of this year.  He is the primary author of three industry standards one ISO standard and two ASTM standards.  He is active in ASTM (sub-committee chair), ASCE (Fellow, and member of the Cleveland Section Board for over a decade, and officer of a national committee on transportation security), ASME (member of a nuclear code committee) and the American Ceramics Society.  

He has nineteen successfully funded research grants during his tenure at CSU.  Since starting at CSU, his research efforts in the field of engineering mechanics as it relates to the design of components fabricated from brittle materials (e.g., ceramics, glass, and graphite) has led to $1,196,229 in grants.  He has an international reputation in the field of designing components fabricated from ceramic materials.  He has authored a number of government and industry reports that will not see the public domain for some time.  Steve has put together a short course on designing ceramic components.  Recently, Steve was asked to participate as a consultant to the Cleveland Clinic on a multi-million dollar NIH grant.  This multi-agency research team is endeavoring to develop the world's first artificial kidney through the utilization of nano-porous ceramic filters - the design of which will prove critical to the success of this effort.  In the near term he will participate with Cleveland Clinic (if funded) on the design of wearable bridge-to-implant or bridge-to-recovery device for patients with acute or chronic lung disease, which will again employ nano-porous ceramic materials to reduce CO2 levels in a patients blood stream.  

His efforts in the field of transportation engineering field has currently generated $1,585,658 in federal dollars for the University Transportation Center with one more year of committed funding, which must be matched dollar for dollar with local cost share.  Currently the local matching funds include $107,000 in private donations.  To date, the Transportation Center has generated another $216,919 in agency sponsored research.  The prospect of continuous federal funding in the next Transportation Equity Act for the Transportation Center is quite good.
