  14. 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

  15. 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’

  16. 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, ...

  17. 1977: Cambridge Distributed System

  18. 1993: Autostereo Display

  19. William Gates Building • A split with the Computer Service • All research under one roof • Two lecture theatres, one practical laboratory.

  20. 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

  21. 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

  22. 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.

  23. 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

  24. 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).

  25. 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.

  26. 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);

  27. 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.

  28. 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’.

  29. 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!

  30. 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.

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

  32. 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

  33. Thank-you and any questions ? • Web www.cl.cam.ac.uk • djg@cl.cam.ac.uk
