Talk Title: Cervical Cancer Prevention: The Quintessential and Persistent Public Health Challenge

Abstract: Effective and cost-effective preventive strategies against cervical cancer have been available for several decades. HPV vaccination and cervical cancer screening hold such promise that the World Health Organization Director General issued a call for the global elimination of cervical cancer as a public health problem in 2018. Despite these available options, cervical cancer remains hugely burdensome with wide disparities in incidence and mortality around the globe, and even within the United States.

This talk chronicles the progress towards cervical cancer elimination over the past two decades and the many remaining challenges. I discuss this quintessential public health problem from the lens of decision sciences as an approach to evidence-based decision making that has informed policy recommendations for HPV vaccination and cervical cancer screening in the United States and globally. Professional development and lessons learned through research collaborations, which were found to be portable to leadership roles more broadly, are shared.

Deeper Differential Expression Analysis with Shrinkage Correction

 

HBC Current Topics in Bioinformatics
Jul 16, 2025 01:00 PM
Register here.
February’s R Basics, or a working knowledge of R, is a prerequisite for this workshop.
Jared Brown, PhD
Postdoctoral Research Fellow, Irizarry Lab
DFCI Data Science
Differential expression (alternately abundance) analysis is regularly a core tool in identifying and quantifying differences between and across groups in -omics data. In this workshop session with follow-along analysis scripts we will take a deeper look at the models underlying differential expression analysis with the particular example being the DESeq2 framework. We will examine questions around design specification, the proper use of pre-computed offsets like normalization corrections, parameter estimation and testing, and robust false discovery rate correction through post-hoc shrinkage. Examples highlighting how these approaches differ across datasets will be drawn from bulk RNAseq, single-cell RNAseq, and ChIPseq.

Complex Disease Modeling And Efficient Drug Discovery With Large Language Models

HSPH Biostatistics and DFCI Data Science Seminar
Tuesday April 29 from 11:00-12:00pm
Zoom only (Link to be posted shortly)

Yu Li, PhD
Assistant Professor, CSE
The Chinese University of Hong Kong

Large language models, which can integrate and process large amounts of data in biomedicine, have great potential in modeling complex diseases and discovering functional biomolecules for potential therapeutics. To model complex diseases and identify the potential drug targets for such diseases, we built a language model trained on the insurance claims of around 123 million US people. With the model, we can give a unified representation of all the common complex diseases, which enables us to predict the genetic parameters of the diseases and discover unique genetic loci related to them efficiently. Then, we developed models based on protein language models to efficiently discover remote homologs and functional biomolecules from nature, such as signal peptides and antimicrobial peptides. With the model, we can identify remote homologs 22 times faster than PSI-BLAST and discover diverse functional peptides with sequence similarity lower than 20% against the known ones. Finally, we developed an RNA language model to model the RNA sequence and structure relation, which enables us to perform RNA structure prediction and reverse design effectively. Within two months, we designed and experimentally validated 19 RNA aptamers that are structurally similar, yet sequence dissimilar, to known light-up aptamers. More importantly, 10 designed aptamers show higher fluorescence than the native Mango-I. The above projects demonstrate the great potential of large language models in promoting fundamental computational biological research and potential transformational development.

The intersection of Al/ML and biomedicine is entering a transformative era, with growing potential to
impact both basic research and translational medicine. Yet, despite remarkable advances in high-
throughput technologies across genomics and cell biology, our understanding of the diverse cell types
in the human body and the underlying principles of intracellular molecular organization and
intercellular spatial interactions remains incomplete. A central challenge lies in developing
computational frameworks that can integrate molecular, cellular, and tissue-level data to advance cell
biology at an unprecedented scale. In this talk, I will present our recent work on machine learning
approaches for regulatory genomics, with a focus on single-cell 3D epigenomics. We introduce methods
that connect different layers of 3D genome architecture and cellular function at single-cell resolution,
including graph- and hypergraph-based models that capture spatial genome organization. I will also
highlight our latest efforts in developing self-supervised learning frameworks to delineate multiscale
cellular interactions within complex tissues, enabling the discovery of previously unrecognized spatially
organized patterns. Together, these Al-driven models provide a foundation for integrative, multiscale
representations of cellular systems, offering new insights into genome structure, gene regulation, and
cell-cell communication. This line of work opens new opportunities toward building cohesive multiscale
cellular models applicable across a broad range of contexts in health and disease.

Fréchet Regression of Random Objects on Vector Covariates and Its Applications for Single Cell RNA-seq Data Analysis

HSPH Biostatistics and DFCI Data Science Colloquium
Thursday, April 3, 2025
4:00pm
Harvard TH Chan School of Public Health, FXB G13

Hongzhe Li, PhD

Director, Center for Statistics in Big Data Vice Chair for Research Integration, Department of Biostatistics, Epidemiology and Informatics, University of Pennsylvania

Population-level single-cell RNA-seq data captures gene expression profiles across thousands of cells from each individual in a sizable cohort. This data facilitates the construction of cell-type- and individual-specific gene co-expression networks by estimating covariance matrices. Investigating how these co-expression networks relate to individual-level covariates provides critical insights into the interplay between molecular processes and biological or clinical traits. This talk introduces Fréchet regression, modeling covariance matrices as outcomes and vector covariates as predictors, using the Wasserstein distance between covariance matrices as a metric instead of the Euclidean distance. A test statistic is proposed based on the Fréchet mean and covariate-weighted Fréchet mean, with its asymptotic null distribution derived. Analysis of large-scale single-cell RNA-seq data reveals an association between the co-expression network of genes in the nutrient-sensing pathway and age, highlighting perturbations in gene co-expression networks with aging. Additionally, a robust local Fréchet regression approach, leveraging neural unbalanced optimal transport, is briefly discussed to explore how cells are temporally organized during the differentiation of human embryonic stem cells into embryoid bodies.
