BHDSC Seminar: “Integrating post sequencing workflows and statistical approaches to improve the robustness of microbial community data analyses”

The Biomedical and Health Data Sciences Collaborative (BHDSC), a cross-disciplinary group formed by the Tufts Clinical and Translational Science Institute (CTSI) and Institute for Clinical Research and Health Policy Studies (ICRHPS) at Tufts Medical Center, invites you to attend an in-person seminar (with a virtual option) at 35 Kneeland Street, 8th Floor Conference room.

Dr. Jacob Nearing will give a talk titled “Integrating post sequencing workflows and statistical approaches to improve the robustness of microbial community data analyses”.


Modern day sequencing technology has allowed researchers to take vast surveys of the various microbes living within numerous environments including the human body, ocean, and soil. Through this work we have found that these microbial communities, termed the microbiome, can play significant roles in their environment’s ecosystem. Yet, while various microbe(s) have been associated with numerous phenotypes such as host health, these results are often not reproducible across studies. There are many reasons as to why this may be the case including the difficulty in matching results between differing sequencing technologies such as 16S rRNA gene sequencing and shotgun metagenomic sequencing or the use of differing statistical models during data analysis. Both of which can result in differing biological conclusions from the same underlying samples. In this presentation, I will highlight my recent research on developing a tool to help address the gap between 16S and shotgun sequencing using phylogenetic placement and the use of uncertainty in difficult to assign taxonomic labels, to provide more clarity during downstream analysis. With the final goal of creating microbial profiles that have higher agreement between differing sequencing technologies. In addition,  I will  present another part of work on evaluating how differing commonly used statistical approaches in microbiome data analysis can result in different biological interpretations. Highlighting the need for more robust approaches to modeling microbiome data in the future.

Speaker Bio

Dr. Jacob Nearing is a postdoctoral fellow in the department of biostatistics at the Harvard T.H. Chan School of Public Health. Under the supervision of Dr. Curtis Huttenhower, he focuses on improving microbiome data analysis through the creation of new bioinformatic tools and evaluating those already present in the current literature. He has expertise in microbiome data analysis, microbiology, and bioinformatic research. During his PhD at Dalhousie University in Halifax, Nova Scotia, he received numerous scholarships to fund his work on the oral microbiome and cancer. During 2022, Nature Communications highlighted his work on microbiome differential abundance analysis as one of the top 25 most downloaded works published in the biology section for that year.

Seminars & Workshops
D&I Interest Group Meeting: “What Taylor Swift Teaches Us about Engaging Stakeholders” w/ Dr. Alysse Wurcel

Join Tufts CTSI’s D&I Interest Group to learn about stakeholder engagement in implementation science!

Tufts Medical Center’s Alysse Wurcel, MD, MS will present “What Taylor Swift Teaches Us about Engaging Stakeholders” via Zoom. An open discussion will follow her presentation.

Dr. Wurcel is an attending physician in the Division of Infectious Diseases and Geographic Medicine at Tufts Medical Center and Assistant Professor of Medicine at Tufts University School of Medicine. She is board certified in Internal Medicine and Infectious Diseases. A graduate of University of Pennsylvania School of Medicine, she completed her Infectious Disease fellowship at Columbia-Presbyterian Hospital and Tufts Medical Center, and received a Masters in Clinical Research from the School of Graduate Biomedical Sciences at Tufts University. She currently provides HIV, hepatitis C care at Tufts Medical Center as well as six local county jails. She is the infectious diseases consultant to the Massachusetts Sheriffs Association for COVID19 prevention and mitigation strategies.
