She pioneered the concept of superoptimization,[2] and designed the Synthesis kernel, a small kernel with a Unix compatibility layer that makes heavy use of self-modifying code for efficiency.[3][4] Life and careerAfter high school, she was given a scholarship to the Cooper Union School of Engineering in Manhattan, where she obtained a bachelor's and master's degree.[5][2] She went to obtain her Ph.D. in computer science from Columbia University in 1992, studying under professor Calton Pu. In October 1992, Massalin joined MicroUnity as a research scientist, where she became responsible for signal-processing modules and software architecture.[5] SynthesisMassalin's first breakthrough product came while studying at Columbia. Massalin developed Synthesis, an operating system kernel that allocated resources, ran security and low-level hardware interfaces, and created executable code to improve performance.[2] Synthesis optimized critical operating system code using run-time information, which was a new insight previous thought impractical.[2] To support Synthesis, Massalin invented object-like data structures called Quajects, which contain both data and code information.[4] Massalin is still working on broadband microprocessors.[11] Personal lifeHer parents were Croatian refugees from Trieste. In the 1940s, they moved Astoria, Queens, New York, where her father became a construction worker.[2] In a 1996 article in Wired magazine, the author Gary Andrew Poole said she "could be the Einstein of our time."[2] She was well known for offering piggy back rides to people she met, which included notable computer scientists such as Dennis Ritchie, Ken Thompson, and artificial intelligence pioneer Marvin Minsky.[14] References1. ^1 {{Cite thesis |author-first1=Calton |author-last1=Pu |author-link1=Calton Pu |author-first2=Henry |author-last2=Massalin |author-link2=Henry Massalin |author-first3=John |author-last3=Ioannidis |degree=Ph.D. |title=Synthesis: An Efficient Implementation of Fundamental Operating System Services |publisher=Department of Computer Sciences, Columbia University |location=New York, NY, USA |id=UMI Order No. GAX92-32050 |date=1992 |url=http://www.scs.stanford.edu/nyu/04fa/sched/readings/synthesis.pdf |access-date=2012-04-25 |lay-summary=https://lwn.net/Articles/270081/ |lay-date=2008-02-20 |dead-url=no |archive-url=https://web.archive.org/web/20170704122520/http://www.scs.stanford.edu/nyu/04fa/sched/readings/synthesis.pdf |archive-date=2017-07-05}} (Also: ACM SIGPLAN Notices, Vol. 22 #10, IEEE Computer Society Press #87CH2440-6, October 1987)[1][2][3][4][5][6]2. ^1 2 3 4 5 6 {{cite magazine |author-last=Poole |author-first=Gary Andrew |author-link=Gary Andrew Poole |date=1996-12-01 |title=Qua |url=https://www.wired.com/1996/12/ffmassalin/ |magazine=Wired |publisher=Condé Nast |access-date=2016-08-23 |dead-url=no |archive-url=https://web.archive.org/web/20170704124039/https://www.wired.com/1996/12/ffmassalin/ |archive-date=2017-07-04}} 3. ^1 2 {{cite web |title=Company: MicroUnity |url=http://www.microunity.com/company/#am |access-date=2012-05-11 |dead-url=no |archive-url=https://web.archive.org/web/20170704124715/http://www.microunity.com/company/ |archive-date=2017-07-04}} 4. ^1 2 {{cite web |author-last=Henson |author-first=Valerie |title=KHB: Synthesis: An Efficient Implementation of Fundamental Operating Systems Services |url=https://lwn.net/Articles/270081/ |website=LWN.net |publisher=LWN.net |access-date=2016-10-27 |dead-url=no |archive-url=https://web.archive.org/web/20170704124312/https://lwn.net/Articles/270081/ |archive-date=2017-07-04}} 5. ^1 {{Cite news |title=In the Land of the Weird, Standing Out Takes a Little Work |url=https://www.nytimes.com/1998/12/24/technology/in-the-land-of-the-weird-standing-out-takes-a-little-work.html |newspaper=The New York Times |date=1998-12-24 |access-date=2016-02-09 |issn=0362-4331 |author-first=Gary Andrew |author-last=Poole |author-link=Gary Andrew Poole |dead-url=no |archive-url=https://web.archive.org/web/20170704124444/http://www.nytimes.com/1998/12/24/technology/in-the-land-of-the-weird-standing-out-takes-a-little-work.html |archive-date=2017-07-04}} 6. ^1 {{Cite web | url=https://www.quora.com/Henry-Massalin/What-is-Alexia-Massalin-creator-of-Synthesis-kernel-working-on-right-now/answer/David-Carpe?srid=WM5&share=1 | title=David Carpe's answer to What is Alexia Massalin (creator of Synthesis kernel) working on right now? - Quora}} }}{{authority control}}{{DEFAULTSORT:Massalin, Alexia}}{{Compu-scientist-stub}} 5 : Living people|American computer scientists|Women computer scientists|Columbia University alumni|1962 births |
