To drive traffic and make your blog more likely to be found, you should make full use of blog directories and tagging services. You haven't mentioned whether you are already doing anything like that but I didn't see any tagging options on your blog. Provide RSS as well if possible. Above all, keep it interesting and different and always write for your readers, not just for you.
Do some research into the potential of contributing to specialist wikis and/or lenses (see Squidoo for example).
Your specialisation is advantageous, so make the most of it. Submit articles online (article repositories) and offline (magazines and journals, etc.) and keep up with carefully targeted link submissions. I noticed that your site includes articles, which are obviously good for varying the content, but are also useful for deep linking.
