Other positions

I was pre-resident fellow in Neurosurgery at the Miller School of Medicine at the University of Miami and the Jackson North Medical Center, where I helped run the Neurosurgery service providing surgical and hospital care to brain and spine patients. 

I was appointed Visiting Investigator at the Memorial Sloan-Kettering Cancer Center, where I worked in the Brain Tumor Center lab directed by Luis F. Parada in the Cancer Biology & Genetics Program.

I worked as a Fellow in the Neurosurgery Unit for Pituitary and Inheritable Diseases lab directed by Prashant Chittiboina at the National Institute for Neurological Disorders and Stroke (NINDS) at the National Institutes of Health (NIH)

Using Social Artificial Intelligence to Modify Collective Behavior in Realistic Networks

Christakis (PI)
06/01/19 – 05/31/23

Role: Research Scientist

The purpose of the study is to design and implement heterogeneous AI-human systems, test them using the Human Nature Lab’s breadboard experimental platform, and implement these systems in real-world social networks to evaluate their effectiveness in promoting cooperation in standard economic model interactions. My role on the project involves designing and implementing behavioral economics experiments using Human Nature Lab’s online experimental platform breadboard, both in online artificial social networks and through “lab-in-the-field” experiments using face-to-face networks (mapped using Human Nature Lab’s Trellis mobile photographic census platform).

Microbiome Biology and Social Networks in the Developing World

Christakis (PI)                        01/01/19 – 12/31/22

Role: Research Scientist

The purpose is to conduct a metagenomic microbiome study of 2,000 people who share face-to-face village social networks in rural Honduras. We are investigating the distribution of the human microbiome across social networks, the reciprocal nature of human and microbial networks, and the role of both of these types of networks on community health, prevalence of chronic conditions, and spread of infections. My role on this project is taking a lead on the design and implementation of metagenomic sequencing methods and GC-MS/MS and HPLC-MS metabolomic profiling. I work on all aspects of the study, from initial idea generation to study design and implementation, to computational bioinformatics and statistical modeling, to manuscript writing.

Master Collaboration and Research Agreement

Christakis (PI)                        04/20/16 – 04/19/21

Role: Research Scientist

The purpose of the Master Collaboration and Research Agreement between the Tata Group and Yale University is to establish a research and knowledge sharing collaboration between Tata and Yale to build a world-class research program focused on mutually agreed upon areas of interest. My work is on randomized controlled trials of network targeting in field interventions and online behavioral experiments on social networks using the Human Nature Lab experimental platform breadboard.

Exploiting Social Influence in Networks to Magnify Population-Level MNCH Behavior Change

Christakis (PI)                       07/01/14 – 12/31/18
Role: Research Scientist, Lead Data Analyst

The purpose of the study is to use detailed understanding of social network structure and function to identify novel ways of targeting influential individuals so as to foster behavioral cascades and population-level behavior change. This objective is achieved by conducting a randomized controlled trial of network targeting algorithms, deployed in a sample of 30,000 people across 172 villages in Honduras, with maternal and neonatal care interventions.

The Role of social Networks in Health and Well-Being

Christakis (PI)                      09/30/14 – 05/31/19

Role: Research Scientist, Pilot Study Lead

Our lab’s Roybal Center’s two overarching goals of our work are (1) to ask significant questions about the role of social networks in producing specific outcomes related to health and well-being, and (2) to develop methods of answering such questions involving real social networks in which behavioral information relevant to health and wellbeing can be measured. My work includes pilot studies on network targeting interventions, on social crowdsourcing for health testing/screening in marginalized communities, and on microbiome metagenomics and social networks.
