  3. Computer Laboratory • Staff • 38 academic staff, • 25 support staff, and • 40 affiliated research staff. • Students • 154 research students (PhD), • 30 Mphil Advanced Computer Science, • 20 Mphil in Speech and Language, • 3x50 BA Undergraduates.

  4. Interactive Formal Verification • Professor Mike Gordon • Viper Microprocessor 1985 • Fast Ring ECL Chip in 1986 • ATM Switch Chip in HOL 90 in 1994 • Formal model of ARM 6 in 2002 • Embedding PSL/Sugar in HOL 2004 • Embedded Crypto Algorithms (ongoing)‏ • Prof Larry Paulson (Isabelle Prover)‏ • John Harrison (HOL Lite Prover)

  5. EDA Spinouts • Qudos – E-beam rapid prototyping, • Virata – Broadband Modems, • Tenison – RTL to C++ modelling, • Azuro – Clock tree synthesis, • Embecosm – TLM Debugging. • Our graduates provided technical lead at ARC, Intel, TransEDA, ARM, PA Semi, ...

  7. Welcome to the CL • The UoC Department of Computer Science • Some history of our department • Admission • Undergraduate Taught Courses • Postgraduate Courses • Research Areas • Supporter’s Club • Women in Computer Science • Graduate Association

  8. The Mathematical Laboratory • Founded 1937, Sir MV Wilkes. • EDSAC ran first stored program 1949 • Thenceforth provided a computer service • Titan, IBM machines, Phoenix • Diploma started in 1953 • Undergraduate Tripos in 1969 • Moved to WGB in 2001 • Rated 5* and ‘Excellent’

  9. 1949: Edsac 1

  10. 1977: Cambridge Distributed System

  11. 1993: Autostereo Display

  12. William Gates Building • A split with the Computer Service • All research under one roof • Two lecture theatres, one practical laboratory. • Intel, Optronics and LCE currently on top floor • Microsoft MSR out the back in their own building.

  13. Heads of Department

  14. Undergraduate Courses • 25% Computer Science (with 75% maths)‏ • 50% Computer Science (with 25% NST)‏ • Full time for years 2 and 3 leading to BA. • Part II General - A one year part II • Diploma - A masters-like conversion course

  15. Admission • Undergraduates admitted by Colleges • Admission requirements: • A-level Maths • One other science A level (pref Further Maths)‏ • A third A-level or international equivalent • Postgraduates (PhD) must find a supervisor who will has an interest in their research

  16. It is about theory of data representation It is about network protocol design It is about the history and future of operating systems It’s about fundamental differences between programming paradigms. What is Computer Science ? • It is not how to use Microsoft Excel • It is not how to design web sites • It is not how to be an IT manager • We don’t even train people in C++ programming.

  17. Computability Semantics Hardware Processor Design Business Communications Spec and Verification VLSI Example CST Subject Areas • Continuous Maths • Discrete Maths • Software Engineering • Programming • Operating Systems • Compilers • Databases • Information Theory and Coding

  18. 3 year Tripos Practical Work • Ia: Java ticks • Ia: ML ticks • Ia: Hardware ticks • Ib: ECAD and Architecture ticks • Ib: Group Projects • II: Project and Dissertation (25% marks).

  19. ML programming demo. • ML is the first language our students see • It is functional (not imperative)‏ • One of the most-advanced languages ever becoming mainstream (almost mainstream). • Aim to teach fundamentals, not arbitraryness. • `If something has been known for 10 years and looks as though it will remain true for the next 10 years, then it’s probably worth teaching’ - RMN.

  20. ML: Three Ways to Add Up (* Mathematician *)‏ fun intsum1(a, b) = (b-a+1) *(a+b) div 2; (* Engineer *)‏ fun intsum3(a, b) = if (a=b) then a else let val midpoint = (a+b) div 2 in intsum3(a, midpoint) + intsum3(midpoint+1, b)‏ end ; (* Computer Scientist *)‏ fun intsum2(a, b) = if (a = b) then a else a + intsum2(a+1, b);

  21. Postgraduate Courses • PhD in theoretical computer science • Can be in any area researched in the department. • 1986: M Phil in Speech and Language Processing (with dept of Engineering)‏ • Fourth Year in School of Technology ? • Currently being planned.

  22. Current Major Research Areas • Programming Languages, Compilers • Security - Smart Cards, Trusted Computing • Systems - OS, Processors, Middleware, Trust, Networks, H/W. • Rainbow - Graphics, HCI, Asynch H/W • Natural Language and Information Retrieval • Theory & Semantics - Quantum, Computability • Automated Reasoning - HVG, Protocols • Projects with MSR, LCE and Intel Research. New areas are covered with new appointments: e.g. Bioinfomatics

  23. Research Area Map Theory and Semantics Users Maths Graphics HCI Proof Media Mobility Networks Language Programs Security Hardware Engineering

  24. Example: Pervasive Computing Trusted computing infrastructure Mobile applications Security of smart cards Correctness of Network Protocols XML Ontology for personal information Rules for control of the home Alternative HCI devices for real-time control and generating `programs’.

  25. Supporter’s Club • 10 to 50 Local Industry Fund Contributors • Originally for local companies • Library and consultancy access • Frequently funds PhD Students • Specialist Lecture Series • Recruitment Fair Once a Year • Well-attended annual dinner!

  26. Women in Computer Science • Sometimes seen as a male profession ? • WICS mission to redress balance. • Currently 4 or so female out of 30 lecturers. • Only 5 to 10 percent of undergraduates • 15 percent of postgraduates ? • WICS regular meetings, open agenda • Women frequently come top in Tripos. • 2002: 26.9% of the 52 female applicants to Cambridge Computer Science were accepted compared to 21.6% of the 416 male.

  27. Graduate Association • Called ‘The Cambridge Ring’ • Recently established, 2002 • 200-300 members • Annual update and dinner • Advice and consultancy • Should become self-funding

  28. Local Industry • 28,000 Hi-tech employees in Cambridge • 14,000 of them in computing/electronics • New companies are always being founded by our alumni
