He has held visiting faculty positions at UMIACS, University of Maryland, College Park (1991-1992) and at the University of Rome, Italy (1983). He was a full-time faculty member of the Department of Computer Science at PUC-RIO, Brazil for 14 years, where he was also chair of CS ('81-'83). Menasce was elevated to the rank of Fellow of the IEEE for "contributions to research and education in performance evaluation of computer systems." He was elected an ACM Fellow in 1997 "For fundamental contributions to education and practice of computer networks and performance evaluation, and material contributions to the establishment of a strong computing industry in Brazil." He was elected a member of IFIP's Working Group 7.3 in 1998 based on his "contributions and accomplishments in the field of performance evaluation." The Computer Measurement Group (CMG) selected him as the recipient of the 2001 A. A. Michelson Award for "outstanding contributions to computer metrics." In 2016 and 2014 he was selected among faculty of all disciplnes of all public and private colleges of Virginia as an Outstanding Faculty Award Finalists by the State Council of Higher Education for Virginia. (SCHEV). SCHEV selected him as a recipient of the 2017 Outstanding Faculty Award. In 2009 he was inducted as an honorary member of the Golden Key International Honour Society. Menasce was one of the two co-founders and the director of the Hyperlearning Center and he co-founded the Center for Smart Power Grids at George Mason University in 2009.

He published over 255 technical papers and was the chief author of five books, including "Performance by Design: computer capacity planning by example," "Capacity Planning for Web Services: metrics, models, and methods," "Scaling for E-business: technologies, models, performance, and capacity planning," and "Capacity Planning and Performance Modeling: from mainframes to client-server systems", published by Prentice Hall in 2004, 2002, 2000, 1998, and 1994, respectively. His h-index is 51 and his work has received over 10,750 citations.

Menasce was the recipient of various prizes, teaching awards, research awards, and best paper awards in the 2014, 2013, and 1997 Computer Measurement Group Conferences; on the Fifth International Conference on Emerging Security Information, Systems and Technologies (SECURWARE-2011); and on the 1995 IEEE International Conference on the Engineering of Complex Computer Systems. He served as the President of the Brazilian Computer Society ('87 to '89) and as the first elected Vice-Chair of ACM's Special Interest Group in E-commerce (2003 to 2005). He was the General Chair of the 2015 IEEE International Conference on Cloud and Autonomic Computing (ICCAC). He was also the General Chair of ACM's 2007 Federated Computing Research Conference (FCRC), the Program Committee co-chair for IFIP's Performance 2005 Conference, the General Chair of the 2003 ACM Conference on E-commerce, the General Chair of ACM's Sigmetrics 1999, the program chair of the research track for CMG's 2000 conference, the program co-chair of the WOSP'2000 conference, the tutorial chair of ACM's Sigmetrics 1998 conference, and tutorial chair of the 2002 CMG conference. Menasce is a member of the Editorial Board of ACM's Transactions on Internet Technologies and a member of the Editorial Board of Elsevier's Performance Evaluation Journal since July 2010. Menasce was an associate editor of the Electronic Commerce Research and Applications journal from Elsevier Science from 2001 to 2006 and a member of the Editorial Board of ACM's Transactions of the Web. He was a member of the Editorial Board of IEEE Internet Computing for several years until 2008. He is an inventor in one US patent and on two US pending patents.

Dr. Menasce has consulted for SABRE (travelocity.com), IBM, United Online (netzero.com), Lockheed Martin, the US Mint, Peakstone Corporation, the Defense Information Systems Agency (DISA), the Ballistic Missile Defense Organization, the US Army, NASA, iXL, Capital One, TIS Labs at Network Associates, Hughes Applied Information Systems, the Center for Excellence in Space Data Information Systems, the National Institutes of Health, InterAmerican Development Bank, the United Arab Emirates University and Jones International University. He served as an expert witness in various alleged patent infringement cases and in an alleged misappropriation of trade secrets and confidential information case. He testified several times in federal and state court as an expert witness in these litigations. Menasce was one of the two founders and CEO, from 1982 until 1991, of a software company that specialized in the development of large software projects and in database management systems.

His areas of interest include autonomic computing, e-commerce, performance modeling and analysis, and software performance engineering. Menasce was the PI of the NSF-funded project Self Architecting Software Systems (SASSY) and is the PI of the AFOSR-funded project RASS: Resilient Autonomic Software Systems.
