Research Focus and Collaboration
The focus of our research is statistical applications. As such our faculty collaborate extensively with research groups within the university: faculty from Biology and Computer Sciences Departments, the College of Education, the School of Public Health, the College of Engineering, and the Fogelman College of Business and Economics. We stress the importance of graduate students' participation in faculty research and collaboration. To ensure that our graduate students get training in analyzing real life data, we have an established internship program for PhD students with the Department of Biostatistics at St. Jude Children's Research Hospital and occasionally with the University of Tennessee Health Sciences Center. Our graduate students also get practical experience through graduate assistantship support from other departments as needed.
明升体育-英超直播The group holds regular research seminars with presentations from faculty and graduate students. Our statistics group and members of the biostatistics faculty from the St. Jude Children's Research Hospital form the backbone of the West Tennessee Chapter of the American Statistical Association (WTASA), an organization whose membership includes faculty and graduate students from the School of Public Health, and the University of Tennessee Health Sciences Center. The WTASA holds monthly meetings and seminars.
In addition to foundation courses in the theory of probability and statistical inference, we encourage every student to take courses in Bayesian Inference, Stochastic Processes, Linear, Generalized Linear and Non-linear Models, Design of Experiments, Statistical Computing, Statistical Programming in R and SAS.
明升体育-英超直播PhD students are encouraged to attend various conferences in their research areas. This is in addition to the conferences and seminars frequently hosted by the Department. Usually, graduate students presenting at conferences get some funding for travel, hotel and meals.
We have a most impressive record of placement of PhD students. Practically all our Masters and PhD graduates obtain employment in universities, industries, colleges or high schools. These include those who are currently employed at top institutions such as Universities of Florida, Maryland, Chicago and Tennessee. Some others have achieved executive positions in pharmaceutical, insurance, and financial industries. Among our masters graduates are heads of department in some of the top private high schools in Memphis.
明升体育-英超直播Summer funding may be available for some advanced PhD students.
Our faculty provide editorial services to top journals that include the Journal of the American Statistical Association, Journal of the Royal Statistical Society, Biometrika, Biometrics, Technometrics, Journal of Statistical Planning and Inference, Journal of Computational Statistics and Graphical Statistics, Statistics in Medicine, Annals of Statistics, and Annals of Statistical Mathematics and Bioinformatics.
