After joining the Trust in 1998 as a trainee, Grant was appointed a consultant and became Head of Immunology in August last year.
The unit diagnoses and treats a number of conditions, including severe allergies, chronic fatigue syndrome and immunodeficiency (which means that some part of the body's immune system is inadequate so resistance to infectious diseases is reduced).
Grant is originally from South Africa and moved to Britain in 1991. Already a qualified doctor, he decided to continue with his studies. He said: "I originally intended to be here for six months but thought that I should do the Royal College of Physician's exams. After the first part I had to finish the second, and haven't looked back since."
Grant genuinely enjoys his work, but recognises that immunology isn't the easiest of jobs to end up in. He said: "Quite often, people only become involved in clinical immunology for one of two reasons: either they have a scientific interest in the subject or they have somehow become exposed to it in postgraduate training.
"Unfortunately, it is not taught very much in undergraduate training and not much more in postgraduate studies either. But it is a very rewarding job. The patients that we treat have often been very poorly and suffering from persistent infections for a long period of time.
"On average it takes eight years from the onset of immune deficiency symptoms to reach a diagnosis due to a general lack of awareness of the condition, so it's fantastic to see people improving after the introduction of treatment."
Grant's spare time is dedicated to his family and a love of music. He said: "I have two young daughters and, as you can imagine, they take up a lot of my time. I'm also a bit of a hi-fi buff, and that's something that I really enjoy. As with any hobby, it's something that you want to improve on and fiddle around with it. I listen to all kinds of music - from classical, blues and jazz to contemporary.
"Saying that though, we've just moved house, so I'm not sure how much time I'll have for hobbies in the coming weeks. It'll take time to get settled in."
