Xueting Qiu

Postdoctoral Research Fellow
Center for Communicable Disease Dynamics, Department of Epidemiology

Xueting Qiu is a postdoctoral research fellow under the mentorship of Drs. Marc Lipsitch and Bill Hanage in the Department of Epidemiology at the Harvard T.H. Chan School of Public Health. Her research at CCDD focuses on understanding the molecular evolution of Streptococcus Pneumoniae and identifying critical genes/loci under selection that shape the pathogen populations. This work can provide a better understanding of evolutionary trajectories of different genes and population…

Madikay Senghore

Postdoctoral Research Fellow
Center for Communicable Disease Dynamics (CCDD)

Madikay Senghore, PhD, joined CCDD as a postdoctoral research fellow working in Hanage lab. His work will further study the role of accessory genome variation in the fitness of pneumococcal clones. He will work closely with Dr. Hanage to develop a model for reconstructing chains of transmission in an experimental mouse model using deep sequencing. Madikay is an award winning early career scientist who was awarded the 2018 Robert Austrian…

Bradford Taylor

Postdoctoral Research Fellow
Center for Communicable Disease Dynamics (CCDD)

Bradford Taylor is a quantitative biologist interested in how the environment shapes bacterial pathogen pangenomes. As a theorist, he tends to tackle questions using some combination of dynamical and statistical modeling. Previously for his PhD, he worked with Joshua Weitz at Georgia Tech to address how multiple phage infections ecologically impact host populations. Next with Joao Xavier, he investigated how the gut microbiome mediates antibiotic resistant infections in immunocompromised patients…

Siyang Xia

Postdoctoral Research Fellow
Center for Communicable Disease Dynamics (CCDD)

Siyang is broadly interested in the dynamics and evolution of the interactions between pathogens and human immune systems, and how vaccines could affect these interactions. In his Ph.D., Siyang studied the mosquito Aedes aegypti, a major disease vector for dengue and Zika virus. His dissertation examined the impacts of human activities on the mosquito’s evolution and the possibilities of using human-assisted evolution to reduce vector-borne diseases. Outside of the lab…
