When I first read Dr. Atul Gawande's Being Mortal and wrote a blog article about it, I have never had any experience of death outside actuarial mortality modeling. I didn’t truly understand the meaning of this word “limit,” especially when it comes to the time we have on this earth. In the past half a year, for the first time in my life, I had to deal with the passing of family members and friends. I gained some new perspectives on life I never had before.
In July 2018, I had the great pleasure of joining a 3-month-old data science team at Cigna on a mission to use machine learning to transform underwriting (The Road Less Traveled: My Decision to Explore Data Science). For two and half years, working alongside data scientists and engineers, I built some cool predictive models using billions of data points. It was a rewarding experience! While in the data scientist role, I wrote down 4 aspects of data science that I greatly appreciated.
