My research interests include functional programming, functional programming environments, and various aspects of design, semantics, and implementation of programming languages in general, such as advanced type systems and their applications. I am also interested in modelling and simulation languages, and how such languages can be improved by using techniques developed in the declarative language community. I got my PhD from Linköpings universitet, where I worked at PELAB (the Programming Environments Laboratory), IDA, on debugging tools for lazy functional languages. The aim was to provide a declarative, source-level view of lazy computations, while making sure that the space and time costs of the techniques are acceptable. After getting my PhD, I was a postdoc within the OASIS project at INRIA Sophia-Antipolis, where I was involved in research concerning a programming environment for Java Cards based on formal semantics. I was also involved in the design of Modelica, an object-oriented, declarative language for non-causal modeling and simulation of continuous systems with discrete features. I then moved to the CS Department at Yale University, where I am worked with Paul Hudak and John Peterson in the Yale Haskell Group on declarative, domain-specific languages for applications such as robotics and vision. This was all within the unifying framework of Functional Reactive Programming (FRP). I have in particular been working on Yampa, our latest FRP implementation, and associated software such as the Yampa robot simulator. At present, I am a lecturer at the School of Computer Science, The University of Nottingham, where I work in the Functional Programming Lab.
My publications, including my PhD thesis, can be found here.
Papers and talks (including slides from a post-graduate course) of a tutorial nature on FRP in general and Yampa in particular can be found here.
Slides for some recent and some not so recent talks I have given can be found here.
A very alpha release of the Freja compiler and debugger can be found here. (Currently binaries only for SPARC/Solaris. Sources available on request.)
Yampa and related software can be downloaded via the Yampa page (out of date, alas).
Ulf Norell has kindly put together an updated distribution that should work with recent GHC installations:

I organised the Midlands Graduate School 2007, which was hosted here in Nottingam, 16 - 20 April, 2007.
I organised the MGS Christmas Seminars 2012.
I have lectured at the Midlands Graduate School regularly since 2005. Slides from some of those years below, including the latest one for 2012:
Some postgraduate courses I have taught or been involved in:
I am currently teaching/coordinating the following modules:

I'm always happy to discuss ideas for individual projects (e.g. Final Year Undergraduate projects (G53IDS) or MSc projects). If you are looking for inspiration, I have compiled a list of suggestions that can be found here. Some are general, some are related to my research interests. Some a quite developed, some are very rough. Have a look. Maybe you'll find something you like, or maybe one of the suggestions will spark your imagination, spawning new and intriguing project ideas.
