He was the founder, chairman and CTO of TidalScale, a software  pioneer which has developed a software architecture called distributed virtual machines.  TidalScale's software, which sits below an operating system and above bare metal hardware, aggregates commodity servers together to create a  single virtual server to address challenging Big Data problems for in-memory SQL and NoSQL databases, large-scale analytics, simulation, and computational genomics.  It allows a customer to take advantage of the hardware economies of scale of commodity servers.  Instead of requiring application software to be customized for a specific computing environment, TidalScale's software allows a customer to tailor the computing environment to the needs of application software with no modification required.  HPE  acquired TidalScale's products and intellectual property in December 2022.

He is also an Adjunct Professor at the Baskin School of Engineering, UC Santa Cruz.  He's a member of two research labs: Languages Systems and Data and the Storage and  Systems Research Center (a.k.a. Center for Research in Systems and Software).

He is also a founding trustee of the Computer History Museum.  He has served on its Executive Committee, its Nomination and Governance Committee, and has been the chair of the CHM Fellows Selection Committee for 15 years. The Computer History Museum published his oral history.  A transcript is available.

In the past, he was an Executive Vice President and Chief Scientist at SAP. At SAP, he and his group explored advanced new enterprise technologies and applications for use in multinational corporate environments. He started SAP's Global Business Incubator, whose goal is to start up new businesses within SAP. He also started and operated the SAP Sponsored Academic Research Program, over five years supporting over 100 sponsored research projects in universities in several countries.  His most recent area of interest at SAP was in designing and building "Enterprise Supercomputers" for Big Data applications.

During 2009-2010 he was in residence as a visiting scientist at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), where he is also currently a research affiliate.

Earlier, he had been Vice President of Product Development and Operations and Chief Technology Officer at InfoGear Technology Corporation, which was acquired by Cisco June 2000.  InfoGear developed an internet-connected phone, called the iPhone in 1997. 

Prior to joining InfoGear, he was a Senior Vice President and a Corporate Officer at Apple Computer, where he led its AppleSoft Division until November 1996. At Apple he was responsible for all system software, including MacOS.  His two main contributions at Apple were the introduction of the Mach Microkernel, which is now used in every iPhone, iPad, and Macintosh, and a study that led to an investment in Acorn RISC Machines, now ARM.  ARM processors are now used in all iPhone, Macs, and iPads, as well as most other mobile devices.

Prior to working at Apple he helped start Encore Computer Corporation, a pioneer in the design and development of shared memory multiprocessors.  Under a DARPA research contract, he and his team developed the idea of hierarchically organized distributed cache coherent shared memory multiprocessos.

Before that worked at Visual Technology, Digital Equipment Corporation (where he worked on the VAX superminicomputer) and SofTech Inc (F-16, B-1).

Throughout his career, he has been involved simultaneously in industry and Academia.  He has been a visiting scholar Stanford University, a research affiliate at the Massachusetts Institute of Technology and a visiting scholar in Electrical Engineering and Computer Science at the University of California at Berkeley. As an instructor, he taught Computer Science at Boston University.

He was on the advisory board of the School of Software and Microelectronics, Peking University, the advisory board of the Department of Electrical Engineering and Computer Science of Northwestern University and the Center for Wireless & Information Technology at Stony Brook University.

He is also a founding member of the IEEE Computer Society's Industry Advisory Board.

Previously, he served on the Advisory board of Viewpoints Research (founded by Alan Kay) and he served as a member of two women's advocacy groups: he was a member of the Board of Trustees of the Anita Borg Institute for Women and Technology, and an advisor to Watermark.

In the past, he has served on several other board: including the Council on Competitiveness Advisory Committee,  the Board of Directors of Congregation Beth David, Saratoga, California, and the Board of Overseers of the Computer Museum in Boston.

He testified before the U.S. Congress on the Emerging Telecommunications Act of 1991.  He has served the Federal government in several capacities.  He holds a Certificate for Distinguished Service from the U.S. Department of Defense for his design work on the programming language Ada.  He served for six years as a member of Defense Advanced Research Projects Agency's (DARPA) Information Systems and Technology group, advising DARPA on information science research priorities.

Here is a list of his publications and speaking engagements.

During the pandemic, he wrote some software to manage Desktop Images (i.e. Wallpaper) on a Mac.  It is written using Keyboard Maestro, and can be downloaded here.

Secure.IO recently published a podcast interview.

Dr. Nassi holds an M.S. and a Ph.D. in Computer Science and a B.S. in Mathematics from Stony Brook University. Stony Brook's Computer Science Department published this announcement.  In 2008 he completed a global leadership development program at INSEAD.
