Question: Which scientist was a pioneer in the computing field, Robert Nalbandyan or Avie Tevanian?
Context: Jiannong Cao is a computer scientist researching distributed computing, parallel computing, pervasive computing, mobile computing, and wireless networking.  He is an IEEE fellow, the chair professor and head of the Department of Computing, Faculty of Engineering at Hong Kong Polytechnic University.  He is also the director of PolyU Internet and Mobile Computing Lab. Robert Nalbandyan (1937–2002) was an Armenian chemist, the co-discoverer of photosynthetic protein plantacyanin, a pioneer in the field of free radicals, and a noted and prolific writer on various subjects in the field of chemistry. The Gordon Bell Prize is an award presented by the Association for Computing Machinery each year in conjunction with the SC Conference series (formerly known as the Supercomputing Conference).  The prize recognizes outstanding achievement in high-performance computing applications.  The main purpose is to track the progress over time of parallel computing, by acknowledging and rewarding innovation in applying high-performance computing to applications in science, engineering, and large-scale data analytics.  The prize was established in 1987.  A cash award of $10,000 (since 2011) accompanies the recognition, funded by Gordon Bell, a pioneer in high-performance and parallel computing. The Association for Computing Machinery's Council on Women in Computing (ACM-W) supports, celebrates, and advocates internationally for the full engagement of women in all aspects of the computing field, providing a wide range of programs and services to ACM members and working in the larger community to advance the contributions of technical women.  ACM-W is an active organization with over 36,000 members. The Bachelor of Computer Information Systems (abbreviated BSc CIS) is an undergraduate or bachelor's degree that focuses on practical applications of technology to support organizations while adding value to their offerings.  In order to apply technology effectively in this manner, a broad range of subjects are covered, such as communications, business, networking, software design, and mathematics.  This degree encompasses the entirety of the Computing field and therefore is very useful when applying to computing positions of various sectors. Michel Raynal (born 1949), is a French computer scientist, active in the field of distributed computing.  His main contributions concern the design of distributed algorithms, fault-tolerance of distributed computing systems (mainly focusing on the consensus problem), and distributed computability.  He has been a professor at the University of Rennes (France) since 1984.  He has co-authored numerous research papers on distributed computing, and has written 11 books.  Since 2013, Michel Raynal has been "Adjunct Professor" at the Polytechnic University of Hong Kong. Avadis "Avie" Tevanian is an American computer scientist.  He was senior vice president of software engineering at Apple from 1997 to 2003, and then chief software technology officer from 2003 to 2006.  He was a long-standing friend of Steve Jobs. Professor Hassan Ugail is a mathematician and a computer scientist.  He is currently working as a Professor of Visual Computing at the School of Engineering and Informatics; the University of Bradford.  Professor Ugail is the first Maldivian to obtain a PhD in Mathematics.  He is also the first and to date the only Maldivian to receive a professorship in the field of Science.  Prof. Ugail's principal research interests are in the area of Visual Computing particularly in the area of 3D geometric design, 3D imaging and computer based simulations.  Prof. Ugail is a leader in the field of Visual Computing and has greatly contributed to the development of the field by successfully delivering a number of high-profile research and innovation projects, publications and international lectures.  He is a member of the UK Engineering and Physical Sciences Research Council (EPSRC) peer review college and also a peer reviewer for several related journals and conferences in his field of research. The Kannada language has come a long way in the computing field starting from initial software related to desktop publishing to portals and internet applications in the current age.  Kannada is the official language of the state of Karnataka in India whose capital city of Bangalore is known as the Silicon Valley of India.  Kannada also entered the Wikipedia world when Kannada Wikipedia was started in September 2004. Terrell Ward Bynum is an American philosopher, writer and editor.  Bynum is currently director of the Research Center on Computing and Society at Southern Connecticut State University, where he is also a professor of philosophy, and visiting professor in the Centre for Computing and Social Responsibility in De Montfort University, Leicester, England.  He is best known as a pioneer and historian in the field of computer and information ethics; for his achievements in that field, he was awarded the Barwise Prize of the American Philosophical Association, the Weizenbaum Award of the International Society for Ethics and Information Technology, and the 2011 Covey Award of the International Association for Computing and Philosophy.  In addition, Bynum was the founder and longtime editor-in-chief of the philosophy journal "Metaphilosophy" (1968 to 1993); a key founding figure (1974–1980) and the first executive director (1980–1982) of the American Association of Philosophy Teachers; biographer of the philosopher/ mathematician Gottlob Frege, as well as a translator of Frege's early works in logic.  Bynum's most recent research and publications concern the ultimate nature of the universe and the impact of the information revolution upon philosophy.
