Sam earned her PhD at the University of Massachusetts Medical School, where her thesis work focused on host/pathogen interactions of the plague bacterium Yersinia pestis. She joined CCDD as a postdoc jointly mentored by Dr. Lipsitch and Dr. Grad. She is now a scientist in Dr. Grad’s lab, where she studies antimicrobial resistance and immune evasion of Neisseria gonorrhoeae.
Corey Peak
(Former Bio) Corey Peak completed his Doctor of Science in Infectious Disease Epidemiology at the Harvard T.H. Chan School of Public Health with two CCDD committee members – Caroline Buckee, his advisor, and Marc Lipsitch. He defended his dissertation entitled “Optimizing Interventions to Control Emerging Infectious Diseases” on March 7, 2017. He is currently an Epidemic Intelligence Service (EIS) Officer with the US Centers for Disease Control and Prevention (CDC).…
Xueting Qiu
(Former Bio) Xueting Qiu was a research associate 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 focused 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…
Talia Quandelacy
(Former Bio) Talia is a PhD student in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health. Her research focuses on understanding micro-scale transmission and immuno-dynamics of influenza in the US and southeast China, co-advised by Drs. Derek Cummings at the University of Florida and Justin Lessler at Hopkins. She is a member of the University of Florida and John Hopkins Infectious Disease Dynamics research groups.
Paul Reeping
(Former Bio) Paul Reeping is a first year doctoral student at Columbia University. He received his M.S. from Harvard T.H. Chan School of Public Health in the spring of 2017. He grew up in Pittsburgh where he also attended the University of Pittsburgh where he studied microbiology. After college, he became a teacher through Teach for America and taught environmental science to 10th graders on the South Side of Chicago…
Madikay Senghore
(Former Bio) Madikay Senghore, PhD, is a research associate working in the 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…
Rinat Sergeev
(Former Bio) Rinat received his PhD in Physics of Semiconductors in Ioffe Institute, Saint Petersburg. Following his innate curiosity, he pursued challenges in a variety of academic fields, from Quantum-Mechanical Processes to Immunology and Epidemiology. His research interests include conceptual analysis, analytical approaches and models in multiple areas. Currently, Rinat is a growing specialist of machine-learning algorithms and algorithmic challenges. His personal interests include Math puzzles, strategic games and politics.
Aimee Taylor
(Former Bio) Aimee Taylor was a postdoctoral research fellow at the Harvard T.H. Chan School of Public Health working under the mentorship of Caroline Buckee. Aimee also has close ties with the Parasite and Vector Genomics group at the Broad institute, where she was previously based under the mentorship of Daniel Neafsey. Aimee received her PhD from the University of Oxford, joint between the Department of Statistics and the WorldWide…
Bradford Taylor
(Former bio) 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…
Christine Tedijanto
(Former Bio) Christine Tedijanto completed a PhD in the Population Health Sciences program, concentrating in Infectious Disease Epidemiology under Marc Lipsitch. Prior to her PhD studies, Christine studied computational biology and business as an undergraduate and worked as a management consultant.
