In each of us, there is a world…

 

…but one person is not just one person. In each of us, there is a world, webbing out, reaching others. Creating reactions—sometimes equal, sometimes opposite. We rush to say, one life gone. But each of us is world. And today a world has been lost.
       - Funeral homily by Father Lantom, Daredevil, Season 2/4, Penny and Dime.

 

 

This Daredevil quote captured a core concept o...

Our lab's work has recently been featured on the Washington University Institute for Public Health blog! The article cites us our Social Networks & Stroke Recovery study and art project as an excellent example of social network analysis, along with other studies on health system financing and cross-disciplinary collaboration at the university. We are definitely honored to be considered among these innovative applications of ne...

Data clustering is a powerful way of visualizing networks through grouping similar data points together according to common attributes. In preparation for our upcoming project on the mobile phone networks of stroke patients, our lab has been piloting the use of data clustering algorithms on our own cell phone data. The data presented here is of a year’s worth of my own cell phone calls.

 

K-Means Clustering

 

To gather our data, w...

Network Video Clips

Network video clips are short 10 second videos that show network change. Through the use of the ndtv R package, we have been able to create visual networks that change over time from stroke onset to 6 months after stroke. The network video clips can be found here.

 

Description

The network clips show the patient surrounded by individuals in their personal network. These are individuals who provide advice,...

What is a research brand?

A research brand was defined by Jeffrey McDonnell as, “your central mission: the particular branch of research you’d like to be truly excellent in and known for.”  It’s important to have because it helps you stay organized and avoid some pitfalls of wasting time, energy, & resources that some junior investigators may run into.

 

How to pick a brand?

First you want to connect your brand with your advisor...

"Interventions will need to target not just individuals or groups but their social circles."

The Public Health Perspective

The main goal of the field of public health is to improve the health of as many people as possible. Public health scholars focus on what proportion of people can benefit from interventions actually benefit. A public health program usually will have a higher likelihood of success if they can work in cooper...

Lab member and artist Lindsay Obermeyer is making her way to the Vogue Knitting LIVE event at Palmer House Hilton Hotel in Chicago. She is giving her first show of the social networks crochet project. This is an example of physican-patient and science-art collaboration. The art is both a beautiful visual representation of the research and a platform to raise awareness about stroke and social networks. Each mandala is modeled a...

Take home point: Functional outcomes after stroke at 5 years are equal to the outcomes at 2 months, which are both less than the outcomes at 6 months. Age and stroke severity are important predictors of these patterns.

 

This study across four European centers had the ambitious goal of measuring recovery 5 years after stroke. This evaluation is far beyond the usually studied 6-month mark, where it is thought that recovery platea...

This study focuses on whether or not Hamilton’s rule applies to humans. Hamilton’s rule suggests that individuals are more likely to altruistically help closer kin and, in turn, receive altruistic help from the same kin. While this rule has been well supported in animal subjects, data on humans has been lacking. Testing for altruism without causing any serious risk to participants proved difficult in many of the previous stud...
