What It Takes to Challenge Conventional Wisdom in Science
Science is often described as a process of discovery: ask a question, design an experiment, follow the data, and revise what we know. In principle, it sounds beautifully straightforward. In practice, it is much harder. Some ideas in biology become so familiar that they stop feeling like ideas at all. They become the background. They shape the diagrams in textbooks, the language we use in lectures, the assumptions built into experiments, and the way entire fields decide what i

Science as Religion, Science as Business
Science is often portrayed as the ultimate objective pursuit: a steady march toward truth, guided by data, reason, and reproducibility. It is the closest thing modern society has to a shared belief system grounded not in faith, but in evidence. And yet, from the inside, science can feel strikingly similar to a religion. There are founding texts and papers that become canon. There are high priests such as senior figures whose opinions carry disproportionate weight. There are o

My Favorite Book
I have always had a theory about science. There is science that feels nice (it answers an important question, it fits neatly into what is known and even moves the needle a bit in the right direction) and then there is grand science (it can give you chills, makes you feel like you just took a dunk in an ice cold bath and gives you at the same time as much elation as trepidation). As a young scientist there is a clear benefit to nice science, it allows you to test hypothesis in

Regeneration Rewritten: Translational Control as a Driver of Tissue Repair
One of the most profound mysteries in biology is why some organisms, such as the axolotl, can regenerate entire limbs, while mammals cannot. For decades, efforts to understand regeneration have focused largely on transcription—the process by which genes are turned on or off. However, this perspective overlooks a critical layer of gene regulation: translation , the step where proteins are actually produced. In this work, we uncover a fundamentally new principle: rapid, selecti

Exploring Ribosomopathies: Understanding Cell Identity at Stanford
A p53-Dependent Translational Program Directs Tissue-Selective Phenotypes in Ribosomopathies Ribosomopathies are a paradox in human biology. Although ribosomes are essential and ubiquitous molecular machines, mutations in ribosomal proteins (RPs) often lead to highly tissue-specific developmental defects . This raises a fundamental question: how can perturbations to a universal cellular machine result in selective phenotypes? In this work, we uncover a mechanistic framework t

A Subcellular Map of Translational Machinery
Revealing how ribosomes are organized, specialized, and regulated inside cells For decades, ribosomes—the molecular machines that synthesize proteins—were viewed as uniform and passive participants in gene expression. This view assumed that all ribosomes were functionally equivalent, translating mRNAs without selectivity or spatial regulation. However, emerging evidence has suggested that ribosomes can vary in composition and may contribute actively to gene regulation. What h

Mapping the Hidden Regulators of Translation
Systematic discovery of ribosome-associated proteins across development, immunity, and disease For decades, ribosomes were viewed as uniform molecular machines—passive participants in gene expression that translate mRNA into protein with little selectivity. This classical view positioned regulation upstream, in DNA and RNA, while the ribosome itself was considered invariant. Our work challenges this paradigm. We now understand that ribosomes are embedded within a dynamic and

Ribosome Diversity Encoded in RNA: From Sequence Variation to Human Physiology and Disease
Hidden Genetic Diversity in the Ribosome The human genome contains hundreds of copies of rRNA genes (rDNA), arranged in highly repetitive arrays across acrocentric chromosomes. Because of their repetitive nature, these regions have historically been excluded from genomic analyses, leaving a major gap in our understanding of human genetic variation. Using long-read sequencing, computational innovation, and biochemical validation, we generated the first comprehensive atlas of r
