Technion-Israel Institute of Technology APPOINTMENTS ( Professor, Associate Professor, Assistant Professor, EXPERIENCE Dr.
Green has authored and co-authored more than 150 papers and reports in
tribology and design, primarily in the fields of gas/liquid triboelements
design, rotordynamics, integrated diagnostics, dynamic analysis of mechanical
face seals, mechanics of viscoelastic dampers and seals, finite element
analysis of elastic-viscoelastic vibrating structures, elasto-plastic
hemispherical contact, and computer aided design of machine elements. In 1986
he received the ASME Burt L. Newkirk Award “in recognition of excellent
technical papers published in ASME Transactions.” In 1993 he was a
Wolberg Visiting Professor at the Technion, and was also appointed as a
Woodruff Faculty Fellow at Georgia Tech. He was awarded the Best Sealing
Technology Paper by STLE-STC (1988), the STLE Walter D. Hodson Award (2001),
and the STLE Frank P. Bussick Best Paper Award (2004). Dr. Green is the
recipient of the ASME 2006 Machine Design Award “for outstanding
achievements and dedication to excellence in design education, innovation,
service and research.” He served as a Technical Associate Editor for
the ASME Transactions, Journal of Tribology (1988-94), then served and
chaired the STLE Awards Committee (1998-2002), as well as the 2005 STLE
Annual Meeting Program Committee (1995-2005). He has been an Associate Editor
for STLE, Tribology Transactions (2000-2007), a Director on the STLE
Board (2004-2007), and the Chair of the Contact Mechanics Technical Committee
of ASME Tribology Division (2005-2007). Currently Dr. Green is the Chair of
the Executive Committee for the ASME, Tribology Division. He is an instructor
and course administrator for the short course of Fluid Sealing Technology
given annually at Georgia Tech. Dr. Green is a Fellow of the ASME and the
STLE. |
