My biomedical scent detection project

For the past year and a half I have been doing a project at a hospital in Toronto (a collaborative project with researchers at Dalhousie University in Halifax) which has been a dream come true in a sense: I have been able to combine my PhD education and 15+ years of experience as a researcher in cell biology and my love of training dogs. The project is in a relatively new and emerging field, biomedical scent detection research, the purpose of which is to investigate whether dogs’ sense of smell can be used to diagnose diseases. In my case the focus is on training dogs to detect a pathogenic micro-organism which is a major concern in healthcare facilities and certain communities. I still need to be cryptic here as the study is not published as we speak, but I want to share some observations and personal thoughts that have been on my mind regarding the training aspect of it.

What did surprise me is that the nature of the research is more or less the same whether you are looking at one cell under a fluorescence microscope or training a whole organism. In both cases you are training the system to obey your will in a way so that you can hopefully prove your hypothesis. On the way there you hit a lot of roadblocks, you take wrong turns and sometimes travel on the wrong path a long way until you realize that you need to backtrack to the previous intersection. It is a lot of fumbling in the dark until you see a glimpse a light. Continue reading
