Yes.  First of all I qualified as a Doctor in 1972 and I have been engaged in the field of forensic pathology since 1974 and during that time I have dealt with many situations where I had to assess skeletal remains.
	During that time, in the 1980's, I developed an interest in facial reconstruction and developed a technique using computerised methodology to do this, in the late 1980's, which since then have been developing and have been improving ever since.  I have also been engaged in other areas in relation to facial identification since the mid-1980's, such as the use of superimposition techniques for examining photographs and overlaying them onto images of skulls, to assess whether they belong to the same person.
	And indeed I have been carrying out research in a number of areas related to facial identification and also the Director of the Human Identification Centre at Glasgow University which was established a few years ago now, initially being in London and then moved up to Glasgow, and where we carried on working in that area, we have been working there ever since.
