In general my academic interests reflect my professional context: computer science and teaching. In broad strokes I continually learn about education, software engineering, computer science, adolescent development, and learning. I'm a professional educator who is always interested in reflecting and sharpening my craft. I wrote my master's degree on helping people with high content knowledge and low teaching skill effectively teach.
For personal reasons I study Parkinson's disease at regular intervals (my father suffered and died from the disease). When I look through the world with a research epistemological frame, I generally look for peer-reviewed, journaled research and credentialed academics to learn from. I'm quite comfortable feeling challenged.
I am probably much to curious and interested in to many things to be a true expert in anything. That being said, I've reduced my scope recently, and prefer to learn more deeply about fewer things than learn a bit about a broader range of topics.
