Staff Profile

Qualifications

• BSc (Hons) Astronomy & Astrophysics (Newcastle) 1982
• PhD Condensed Matter Physics (Newcastle) 1985
  

Roles and Responsibilities

• Foundation Physics Laboratory Organiser in Semester 1.
• NMR Lab Server administrator.
  
• Module leader for PHY1025, PHY3020, SFY0014, SFY0015 and SFY0016.
  

Research Interests

Theoretical and computational chemistry. Data visualization and visual programming. General methods in quantum and classical mechanics.

Other Skills

Web/database programming (particularly using Ruby on Rails, PHP/MySQL, Perl) and some aspects of website maintenance. Linux system administration and integration with Windows domain networks.

Current Work

Analytical methods in quantum well systems. Ab-initio quantum chemical calculations on mixed amine structures. I work mainly in the Molecular Photonics Group.

 Recent Computational Development

• Software to calculate eigensolutions for square wells and barriers and produce a TikZ graphic to display them.
  
• Wrote a database for COSHH and unattended experiments.

 I have written and continue to maintain the following software:

• Development of the AIMproDX molecular visualization system for the graphical analysis of AIMpro result files. (AIMpro is an ab-initio density-functional molecular modeller written by Patrick Briddon)
• Development of font2dx — a system to convert outline fonts (Type 1, OpenType, Truetype) to OpenDX format.
• Development of dvidx — a TeX DVI driver for OpenDX output. Related to this is the development of a LaTeX interface to OpenDX called DXFontutils.
  
  

 Much of the above work was published in the international computer typesetting journal TUGboat (TUGboat, 25-2,2004,p177—188). AIMproDX is used in several universities in the UK, Europe and North Africa.

Postgraduate Supervision
