Why I teach Data Science at Harvard Extension School
It is always a rewarding experience to work with the talented students enrolled in courses. I am happy to have the opportunity to share my passion and expertise with our great Division of Continuing Education students.
I have always been fascinated by the analysis of data and the application of analytics. Working on some kind of interesting data-intensive problem always makes me happy. I really like the challenge of trying to find meaning in complex data problems.
I have spent my career focused on data intensive analysis and large-scale computing. My varied career in technology has allowed me to dive into many application areas.
I have had so many great interactions with DCE students over the past 6 years. I suppose my favorite interactions are with students working on individual projects. HES students bring a lot of passion and energy to their projects. I try to provide guidance as students work though the inevitable twists and turns of a project.
Student projects have encompassed a wide range of data science topics from building an AI agent to create dance music, modeling the spread of COVID-19 or determining the rate of melting of the world’s mountain glaciers.
