I. Biographical Sketch
The Technical University of Wroclaw, from which I graduated, is one of the largest technical universities in Poland. At the time of my graduation in 1982, the University consisted of approximately 30 large research institutes, 10,000 undergraduate and M.S. graduate students and approximately 1,000 graduate Ph.D. students in a variety of technical and scientific disciplines with the exception of life sciences. For 2002 and 2003, the Technical University of Wroclaw was ranked #1 among all technical universities in Poland in several national rankings.
As an undergraduate student, I followed an individual teaching program specially designed for me which allowed me to study not only what was available at my university but also at the University of Wroclaw, a large liberal arts university, and the Mining Academy in Krakow. In the Department of Mathematics at the University of Wroclaw, I studied theory of probability and statistics, and at the Mining Academy, electron microscopy. My Ph.D. program in Applied Mechanics and Materials Science was jointly sponsored by the Technical University of Wroclaw and the National Science Foundation (NSF) of the United States of America (Marie Curie Foundation, International Programs). My Polishacademic advisor was Professor L. Golaski, whereas Professor K. Ono from the University of California Los Angeles (UCLA) was my American advisor. As part of my Ph.D. program, I was invited in 1981 by the NSF to visit UCLA as well as other research organizations in the USA. That was my first contact with the US.
After graduating in 1982, I was appointed an Assistant Professor of Applied Mechanics and Materials Science at the University of Wroclaw. Then, in January 1984, due to mostly economic reasons, I decided to leave Poland and seek academic employment abroad. Initially, between January 1984 and December 1984, I worked as a Visiting Research Fellow at the University of Liverpool. Then, in January of 1985 I moved to Cambridge, England, where my family and I spent six fascinating years. In the Department of Materials Science and Metallurgy at the University of Cambridge working with Professor D. Hull, FRS, I was exposed to state of the art material science research and, in particular, advanced composite research. The knowledge and experience I gained at Cambridge shaped my entire academic career in subsequent years.
In 1990, I left Cambridge and accepted an academic appointment at the Oregon Graduate Institute of Science & Technology (OGI) in Portland, Oregon. Between 1990 and 1996 I worked at OGI in two departments; initially in Materials Science and Engineering and then Applied Physics and Electrical Engineering. In 1996 due to family reasons I decided to leave OGI and accepted an academic appointment in the Department of Engineering at the University of Denver (DU), where I am presently a tenured Professor of Mechanical Engineering. In 2006 I became a John Evans Professor at DU (http://www.du.edu/facsen/facultyhonors.html#A).
As part of my academic duties I am:
a)the Chair of the Mechanical and Materials Engineering Department (newly established in July 2007)
b)the Director of the Center for Nanoscale Science and Engineering (a large interdisciplinary center recently created at DU consisting of faculties of several DU departments)
c) a coordinator of our interdepartmental Materials Science program at DU with graduate Ph.D. students from three departments. I am also managing the Center for Advanced Materials and Structures at DU (http://www.engr.du.edu/CFAMS/CFAMS_Home.htm) that I established in 1996.
II. Publication Record
As of September I have published 93 international journal papers, 45 papers in international conference proceedings, and 15 major final research reports.

Industrial Relevance
At the Oregon Graduate Institute of Science & Technology I was initially involved in the failure analysis of advanced metallic alloys for jet engine applications. As part of a project jointly supported by the General Electric Aircraft Engines (GEAE), Precision Castparts Corporation, State of Oregon and the Federal Bureau of Mines, my first research group in the US investigated the resistance to high temperature fracture and fatigue of nickel based superalloys and titanium aluminides. At the same time, I started developing, quite successfully, research programs in the area of polymer matrix composites, which was more consistent with my research experience gained at Cambridge. The polymer matrix composite research programs developed at OGI I have moved and further expanded at DU. Since leaving Cambridge in 1990 I have received approximately 3 million dollars in various grant and contract awards.
My main research activities at DU between 1996 and 2005 were related to the use of polymer matrix composites either at elevated temperatures or in high voltage electric field applications. The programs were supported by two different groups of federal and private sponsors.
Between 1993 and 2006 I supervised major research efforts in the area of high voltage composite insulators. The insulators are widely used in transmission line and substation applications in the US and abroad. In-service, the insulators are subjected to the combined action of large mechanical, electrical and environmental stresses. Due to the presence of these stresses, catastrophic failures of the insulators have occurred in-service over the last several years in many regions of the world. The primary goal of my insulator research was to understand the fundamental mechanisms leading to the premature mechanical and electrical failures of the insulators in-service and to improve the design of the insulators. This research was extensively funded through multiple contracts by the Electric Power Research Institute (EPRI) and a consortium of electric utilities and insulator manufacturers consisting of the Bonneville Power Administration (BPA), the Alabama Power Company (APC),the Western Area Power Administration (WAPA), Pacific Gas & Electric (PG&E), the National Rural Electric Cooperative Association (NRECA) and NGK-Japan. Thanks to the generous support of the sponsors, my research groups, initially at OGI and then at DU, made major contributions to composite insulator technology. Our most important accomplishments in this area are listed below and consist of:
- Explanation of 345 kV and 500 kV brittle fracture failures experienced by WAPA and PG&E
- Identification of the type of acid responsible for brittle fracture
- Simulation of brittle fracture with and without high voltage
- Identification of several critical conditions leading to brittle fracture and other mechanical and electrical failures
- Providing a ranking of the commonly used GRP rod materials for their resistance to brittle fracture and other failure modes (electrical, overcrimping)
- Recommendation of numerous experimental and numerical procedures critical for insulator design.
Most of my insulator research has been published in several major IEEE journals. You can read my IEEE papers at http://www.engr.du.edu/CFAMS/CFAMS_Downloads.htm.
The other area of my research at DU was the numerical and experimental failure analysis of advanced high temperature graphite/polyimide systems for aerospace applications. The primary goal of this research was to understand failure mechanisms in high temperature composites based on medium and high stiffness graphite fibers and various polyimide resins. Particular attention was given to determine the effect of physical and chemical aging on the strength properties of the composites as a function of temperature and biaxial loading conditions. Jointly with NASA, Boeing and several other major US industrial and academic organizations we were involved in the development of multidisciplinary technologies for affordable propulsion engine components that would enable the system to operate at higher temperatures with reduced cooling while sustaining performance and durability (http://www.grc.nasa.gov/WWW/RT2002/5000/5150sutter.html). As part of these efforts, high temperature polymer matrix composites and fabrication technologies were developed suitable for manifolds, thrust chamber supports and attachments. The usage of such composites should allow the replacement of heavy metal engine components to provide a high thrust to weight ratio. This research was extensively funded for several years by the National Science Foundation (three consecutive grants), Air Force Office of Scientific Research (five consecutive grants), and the NASA Glenn Research Center (three contracts).
