Welcome to the web-page for Jackie Daykin, Computer Scientist.

My research interests include big data topics such as pattern inference & compression, stringology algorithmics & data structures, and computational combinatorics involving for instance graphs & posets. The application focus is bioinformatics. An exciting development is that I have recently been appointed Sêr Cymru II Fellow in the Department of Computer Science at Aberystwyth University, Wales.

Erdos number

From time to time it is a surprise when someone approaches me to say with interest that my Erdos number is 2! This is indeed the case, but let me explain that this elated/elevated number is simply due to publishing with my father, David Daykin, who published jointly with Paul Erdos. Think of me as a chipette off the old block!
