We are happy to announce that our work exploring the role of the microbiota-gut-brain axis in understanding and influencing components of adverse post-traumatic neuropsychiatric sequelae (APNS) got published today. By analyzing stool samples from trauma-exposed emergency department patients, we identified specific gut microbial species and metabolic pathways associated with worse APNS outcomes.

The position is funded via Bill and Melissa Gates Foundation grant to the Bucci Lab.
The selected candidate will work on the development of novel dynamical systems modeling and deep learning methods to predict the dynamics of the microbiome and how they impact host immunity. Applications of these methods will include forecasting microbial population and metabolite dynamics that are constrained on longitudinal data from human clinical trials, predicting interactions with the host immune system, and using the models to perform combinatorial analysis to identify microbial combinations and functions maximizing host phenotypes of interest.
This project provides an excellent opportunity to learn and further develop a variety of computational modeling, bioinformatics, and deep learning techniques. The selected candidate will work independently to design and execute experiments. Results of this project will be presented at seminars and scientific meetings, which may involve travel. The post-doctoral fellow will also prepare and submit manuscripts and may assist with grant preparation.
Qualifications: Education, experience and skills required for consideration:
- Ph.D. in quantitative sciences including Math, Physics, Engineering
- Required experience with development and running of mathematical models
- Required experience with inferential statistics
- Required experience with solving Ordinary and Partial Differential Equations numerically
