As someone who studies state and federal policies, I spend a lot of time trying to identify natural experiments that can provide a degree of causal insight into the effects of certain policy choices. Many studies suffer from a lack of causal design and cannot go beyond simply finding correlations, which may be biased by … Continue reading Visualizing Difference in Differences Studies
This past weekend, myself and a friend of mine competed in a triathlon in downtown Indianapolis. The group that organizes the race does a great service by publishing all of the athletes' final times along with event splits in one big table after the race. Having done a few of these races now, I thought … Continue reading Visualizing Tri Indy Race Results
I've been working this weekend on a couple of papers related to scooter trips and public safety, which has involved a review of the existing peer-reviewed evidence and reports from Bird and others on scooter safety and related municipal priorities. Inspired by Portland's heatmap of the most popular hours for scooter trips for each day … Continue reading When do people scoot?
We are hot off the presses with some new scooter stats, having received data for January through March of 2019. As you might imagine, scooter usage in Indianapolis is starting to recover with the warming temperatures and longer days. For readers in Indy, use those extra hours of sunlight we get by virtue of our … Continue reading Lime Scoots Ahead in 2019
A few weeks ago, I posted some preliminary statistics on Bird and Lime electric scooters (aka dockless mobility devices) in Indianapolis, comparing the scooters here to those in Louisville. I then spoke with Alison Griswold at Quartz to refine the population of scooters we were analyzing, and have since updated the numbers. The main takeaway … Continue reading Update to Scooter Stats
I was lucky enough to join two of my colleagues from the Fairbanks School of Public Health and Regenstrief for a hackathon in Haifa, Israel where we built a prediction model and visualization tool for congestive heart failure risk among diabetic patients.
Note: an update to this analysis was posted March 27, 2019 March 5, 2019 Update After publishing this, I was able to chat with Alison at Quartz (new newsletter out today) and talk through some of the methodological differences between what Nathan (Louisville) and I did. I wanted to update the post with some new … Continue reading Bird & Lime Scooters in Indianapolis, Fall 2018 Edition
I've been working a lot lately with the CDC's Opioid Prescribing Rate data I posted about in May. A fellow grad student at IU, Kevin Wiley, and myself, have been working on an RShiny app for visualizing maps of this data and the trends over time. We have a lot left that we want to … Continue reading Visualizing State-Level Changes in Opioid Overdose Deaths
The opioid epidemic regularly garners national headlines, and numerous new and ongoing efforts are attempting to curb the overprescription of opioids in this country. For example, here in Indiana, IU has already invested in 16 projects as a part of the Addictions Grand Challenge. The university-government partnership is currently preparing for the second phase of proposals proposing novel … Continue reading Opioid Prescribing Rate Trends in Indiana, 2006-2016
I typically have no reason to post photos; most pictures I have are screenshots of articles or pictures of my mom's cats being lazy cats. But I just can't keep these to myself. My cousin, uncle and I hiked Mount Verstovia in Sitka, Alaska today. We summited Arrowhead, roughly 3,000 vertical feet of climb … Continue reading Mount Verstovia in Sitka, AK
