Hi! I'm David Grethlein and I currently study as a PhD candidate (and work as a research assistant) for the Games, Artificial Intelligence, and Media Systems (GAIMS) Center at Drexel University. Concurrently, I worked as a Data Scientist at Diagnostic Driving, Inc. in West Philadelphia. My job largely revolved around analyzing and visualizing driving simulator time series data with the goal of improving driver on-road safety using Simulator pre-screening.
I graduated (cum laude) with a Bachelor's of Science in Mathematics and 2 minors in Mandarin Chinese and Computer Science from Drexel University in 2017. At the same, I graduated with honors from the Pennoni Honors College, also at Drexel University.
Since graduation, I have been enrolled as a PhD Student in the College of Computing and Informatics at Drexel University where Santiago Ontañón PhD has been my research advisor. In the time as a graduate student there we have co-authored several works with some published and others still currently in submission (Google Scholar Profile).
I am currently researching time series supervised and unsupervised learning methods. My work largely focuses on developing methods for automatically detecting and characterizing prototypical behaviors in time series data (Github Profile).
