Heriot-Watt University



The last year has been one of considerable change for the Department of Mathematics at Heriot-Watt. Two long-standing members of staff, Professor Robin Knops and Mr Jim Bree, retired during the year. Robin Knops has been at Heriot-Watt for 27 years, including periods as Head of Department, Dean of Science and Vice-Principal; we are pleased that he continues to be involved in the local mathematical community through ICMS and ICIAM99.

In 1998 we were pleased to honour one of our former colleagues, Professor John M Ball, FRS, who was given an honorary degree in the July graduation.

The department has also welcomed many new faces during the year, which started with the arrival of Professors Sergei Kuksin and Jonathan Sherratt, and Dr Robert Weston. During the summer, Drs Chris Boulter and Paul Turner were appointed, and joined us later in the year, and we look forward to the arrival of Drs Jan Kristensen and Andrew White, who have recently been appointed.

With these new appointments, our research activity continues to grow and broaden. An exciting development during the year was the award of a prestigious grade 1 to a Teaching Company project, lead by Dr Dugald Duncan and Professors Chris Eilbeck and Andrew Lacey, in collaboration with Edinburgh Petroleum Services, and follow-up projects are building on this success. Mathematical biology is growing within the department, and a Scottish Theoretical Biology Forum, part-led by Professor Jonathan Sherratt, was established during the year. Professor Cliff Beevers and the CALM group went from strength to strength, gaining a major contract in 1998 for the development of computer examinations for use in the Far East.

As in previous years, members of the Department made several invited lectures at international conferences.  Most notable of these was the invited address given by Professor Sergei Kuksin at the International Congress of Mathematicians in Berlin.

In 1999, we look forward to a number of scientific meetings run by members of the department at the International Centre for Mathematical Sciences, and to the Fourth International Congress of Industrial and Applied Mathematics, coordinated by Professor Jack Carr and Dr Michael Levitin, which will bring several thousand mathematicians to Edinburgh.
