CURRENT POST

September 1995 to the present,

Research fellow in the Divisions of Clinical Decision Making and Cardiology, Tufts-New England Medical Center (50%)

Research affiliate in the Clinical Decision Making Group at the Laboratory for Computer Science of the Massachusetts Institute of Technology (50%).

I have spent three years working on the Heart Disease Program, a large expert system (based on a modified Bayesian Belief Network) developed by Bill Long to assist with the diagnosis of heart disease. During that time we developed a new user interface and have increased the knowledge base considerably, adding new diseases from cardiology and general medicine in the light of the evaluation work.

MD Project Work

I have designed, set up and performed a clinical trial of the Heart Disease Program with physicians (mainly residents) at the New England Medical Center. We developed the user interface as a Web site to allow physicians to access the program over the Internet. 127 cases have been directly entered by participating physicians and 50 entered over the Internet from around the world, many by cardiologists. This work has been presented at the American Medical Informatics Association, the American College of Cardiology and the British Cardiac Society meetings. The work is forming the basis for an MD thesis submission to Edinburgh University.

Machine Learning/Data Analysis

My second major area of work has been in using tools from machine learning and statistics to develop decision support tools from data. I started this area of work with Dr. Lee Kennedy in Edinburgh, developing models to predict the diagnosis of myocardial infarction in patients with chest pain. I continued this work with Bill Long and Chris Tsien at MIT exploring ways to optimise decision trees induction, improve generalisation of models over data collected in different countries and to deal with missing data.

In 1997/98 I received funding from Pfizer Inc. to develop models that can predict adverse events in clinical trials. Techniques applied to this problem included machine learning, logistic regression and backpropagation neural networks. I continue to be interested in the detection of trends over time, and the use of patterns in medication to predict adverse events.

Patient Directed Decision Support Tools

My most recent grant is from the National Heart Attack Alert Program, a group funded by the NIH to explore ways to assist patients with myocardial infarction to recognise and act on their symptoms early. I am assessing the performance of current patient guidelines on data from Edinburgh and Boston. I am running a randomised trial to assess the effect of patient educational materials on the ability of patients to recognise and act on symptoms of MI. In addition we are exploring the use of the Internet and palm top computers to provide teaching and advice to patients with heart disease.

CAREER INTENTIONS

I intend pursuing a career in Medical Informatics/Artificial Intelligence with a particular emphasis on the application of these techniques to cardiology. Experience in the US suggests that researchers with both medical and computer science training are particularly productive in this field. Having completed the majority of my clinical training in cardiology and with experience and qualifications in AI/computing techniques, I am keen to continue working in both Informatics and Cardiology. I will submit this work for a British MD thesis (similar to a PhD) at Edinburgh University, which can be based on work performed abroad.
