Here are a few lines as recommendations about my professional experience, work and attitude from various people around the world.

John S. Kay, P.E., CLGS

Vice President – Engineering, STRATCO, Inc., Scottsdale, Arizona, USA
(part of Green card support letter)

Dr. Biro has in-depth experience in the field of high performance modified asphalts, which is a critical core competency in a key industry served by both STRATCO and its sister company, ECOPATH Industries LLC.  Dr. Biro gained commercial experience in this field and also graduate level training in the USA, including crumb rubber modified asphalt, which is a very specialized niche product in the modified asphalt industry.  He also has experience and knowledge in the use of modified asphalts used in the manufacture of asphalt roofing shingles, which is a specific target market of STRATCO.  Such expertise is very rare in the world, especially when coupled with extensive laboratory experience, which is crucial in developing these and related technologies.

Dr. Biro also has specialized training and experience in the manufacture of lubricating greases, which is the most prominent specialized offering of STRATCO throughout its 80+ year history.  Experts in this field are also in very limited supply in the world.

Khaldoun Shatanawi, Ph.D.

Assistant Professor, University of Jordan, Amman, Jordan

Dr. Biro is an experienced engineer with very practical thinking. His novel approaches, versatility and diverse base of knowledge related to the asphalt and hydrocarbon fields always resulted in high quality outcomes.
He knows how to get people involved and can effectively handle many different projects at the same time. It is a true delight to work with him.


Leonid Kolerov

It is pretentious of me to judge individuals of Dr. Biro’s qualification, however I can say without hesitation that Dr. Biro is among the finest engineers that I have met.

Serji Amirkhanian, Ph.D. 

Director of Research and Development for Phoenix Industries of Las Vegas, USA

Dr. Biro joined my research team at Asphalt Rubber Technology Service (Clemson University) several years ago as a Post-Doctoral Research Scientist.  His responsibilities included performing research in the area of Rubberized Asphalt Concrete (RAC). Dr. Biro’s technical knowledge and his contributions to this field are making enormous improvements to the technology development and practical utilization of RAC, not only as a researcher, but also as a mentor to undergraduate, graduate students, researchers and practitioners.

Further, Dr. Biro has unique multidisciplinary scientific skill sets that are needed for frontier and in-depth asphalt technology and pavement materials research and field applications. Dr. Biro has contributed significantly to the field of rubberized asphalt and on the rheological and mechanical properties of asphalt rubber. Dr. Biro’s research projects conducted at Clemson University has contributed to the body of the knowledge in this area of science.  His work has been referenced in many scientific journal papers around the country.

He was involved, while at Clemson University, with cutting edge research activities.  In this area of research, Dr. Biro conducted very high caliber of work that sets him apart from many other researchers.
