Our lab studies how pathogens evolve and spread. We use experimental and computational tools to test our hypotheses, and collaborate with clinical and public health institutions. We focus on questions of antibiotic resistance, within-host evolution and between-host transmission, and pathogen response to host immune pressures. Our overall aim is to improve diagnostics, therapeutics, and clinical and public health strategies to aid in the control of infectious diseases.
Updates from the Lab
Mar 2019 Congratulations to Jess on being named a Harvard College PRISE (Program for Research in Science and Engineering) fellow for this summer!
Mar 2019 Thanks so much to the Broad Institute for the BroadIgnite award! I’m very excited for the support for this project!
Feb 2019 Thrilled for Crista, who will become an assistant professor at the Rochester Institute of Technology starting this summer! Very proud and excited to see you achieve exactly what you aimed to do when you started as a post-doc!
Feb 2019 Congratulations to Mohamad, who has accepted an offer at Day Zero Diagnostics for a position as Senior Computational Biologist. Bittersweet, but we’re excited for your new venture!
Feb 2019 A new manuscript from Scott in which we use modeling and empirical data to start to tackle the following questions: what’s the right geographic scale to test outpatient antibiotic stewardship interventions? How much does spillover from neighbors impact results?
Feb 2019 Crista’s new pre-print on developing RNA-based diagnostics for antibiotic resistance detection in gonococcus and the importance of considering population structure in doing so is now up on bioRxiv. Great work, Crista!
Jan 2019 Yonatan had a great time visiting the Institute of Microbiology and Infection at the University of Birmingham, catching up with colleagues and friends, and meeting new ones. Thanks for having me!
Jan 2019 Hurray for Scott, who accepted a job offer as Scientific Director at OpenBiome! The lab will miss you, but we’re excited to see the amazing things you’ll do!
Dec 2018 Congrats to Scott and our co-authors on the publication of The distribution of antibiotic use and its association with antibiotic resistance in eLife! We show: 10% of the population in the US uses 57% of the antibiotics; around 1/3 of people take an antibiotic every year; for most of 72 pairs of antibiotics and bacteria, there’s a positive correlation between use and resistance across the US; breadth of use (the fraction of the population consuming antibiotics) is more positively associated than repeat use with resistance in a population.
Dec 2018 Yonatan gave a keynote lecture at the One2Many systems biology conference at the Weizmann Institute. Such an honor to be invited by the graduate students!
Nov 2018 Allison and Kevin both spoke at the Wellcome Genome Campus meeting on “Antimicrobial Resistance – Genomes, Big Data and Emerging Technologies” — and Kevin received a commendation for his talk. Well done, Allie and Kevin!
Nov 2018 Yonatan gave a lecture in the NDPIA/IBA course on ”Antibiotics and Antibiotic Resistance” at Hjortviken, Hindås / Gothenburg. Great course, wonderful students and faculty.
Nov 2018 The 2nd SMBE satellite workshop on pathogen genomics was fantastic! A community of scientists and public health folks, all eager to apply innovations in genomics to disease control. Thanks so much to the organizers for the invitation and opportunity to participate!
Oct 2018 Yonatan visited NYC for the Doris Duke Charitable Foundation Clinical Scientist Developmental Award meeting — inspiring to hear about a lot of exciting science, meet new colleagues, and catch up with old friends.
Oct 2018 Yonatan had a great trip to Indiana University School of Medicine — thanks, Dave Nelson, for the invite! Fun to learn more about the exciting ongoing work, meet colleagues, and share what we’re up to.
Sept 2018 Kevin and Yonatan attended the International Pathogenic Neisseria Conference, where Kevin presented a poster of his GWAS work, and Yonatan had the pleasure of presenting work by Sam and Crista. Great conference, wonderful community.
Sept 2018 Scott’s paper on racial/ethnic disparities in antibiotic use, using MEPS 2014-15 survey of prescription fill rates, is now up at Emerging Infectious Diseases. Whites use more antibiotics (across all classes) than all other races/ethnicities. Raises many questions, including how this may impact on emergence and spread of AMR.
Sept 2018 New preprint up on bioRxiv, in which we present a Bayesian model of acquisition and clearance of bacterial colonization, with the goal of improving on the heuristic SNP distance often used to say whether two isolates represent the “same” strain. Great work led by Marko Järvenpää and together with Pekka Marttinen and a wonderful group of collaborators.
Aug 2018 Scott and Yonatan attended and spoke at the STD Prevention Conference, with Scott talking about his project investigating the relationship between seasonal variations in azithromycin prescribing and resistance in gonococcus and Yonatan presenting on modeling to help slow and control the spread of resistance. CDC colleagues presented data showing a continued and marked increase in rates of gonorrhea and the extent of resistance — lots of work to do!
Aug 2018 Crista’s paper on gonococcal acquisition of azithromycin resistance through interspecies recombination (and a lot of great work exploring epistasis and integrating population genomics and basic microbiology) is now out at mBio. Highlighted in an accompanying commentary!
July 2018 Scott’s paper on trends in antibiotic prescribing in the elderly is now out at BMJ.
June 2018 Yonatan gave a talk on mumps at the Virus Genomics and Evolution meeting at the Wellcome Genome Campus. Excellent meeting!
June 2018 Tatum and Yonatan’s review on genomics and MDR gonococci is now out.
Apr 2018 Congratulations to both Daphne and Allison on passing their PQEs!
Mar 2018 Our paper on the resurgence of mumps in highly vaccinated populations is now out in Science Translational Medicine.
