My lab has been involved in projects at the forefront of devising novel technologies for high-quality genome sequencing, assembly, evaluation, and annotation, beginning with the Avian Phylogenomics Project, which we published in 50 papers in 2014-2016, and currently with the Vertebrate Genomes Project (VGP) since 2016, The Earth Biogenomes Project (EBP) since 2018, the Human Pangenome Reference Consortium (HPRC) since 2019, and the Telomere-to-Telomere consortium (T2T) since 2019. The aim of the VGP is to generate near error-free, chromosomal-level, and haplotype phased genome assemblies of at least one individual each representing all ~70,000 vertebrate species; the aim of the EBP is to generate reference genomes for all eukaryotic species; and the aim of the HPRC is to generate high-quality genome assemblies from 350 people (700 haplotypes) representing over human genetic diversity, and create a new human panspecies reference. These genomes are becoming the main references in the public databases, to be used by researchers to address currently unanswerable questions without them, such as the genetics of complex traits and associated diseases. Our highquality genome assemblies are providing a unique level of genomic resolution and precision to discover hitherto elusive structural genomic variants relevant to disease in humans. My lab has published more than 200 papers, with students and post docs, which have been collectively cited over 25,900 times to date (hIndex of 74 in Google Scholar as of May 2022). Thus, I believe I have past evidence of the skills and leadership experience necessary to carry out this project.

Jarvis uses song-learning birds and other species as models to study the molecular and genetic mechanisms that underlie vocal learning, including how humans learn spoken language. He is interested in how their brains, and ours, have evolved to produce this complex behavior. Among his objectives for his NIH lecture, Jarvis hopes to impart an understanding of the relationship between vocal learning brain pathways and other brain circuits, as well as an hypothesis on how it evolved out of a preexisting motor brain pathway that controls learned movement. He will also discuss what happens when genes are mutated leading to speech disorders.
Learning Objectives:
- Distinguish the behavioral and neural components of spoken language, and why vocal learning is the most specialized
- Understand the relationship of vocal learning brain pathways with other brain circuits, and the hypothesis on how it evolved out of a preexisting motor brain pathway that controls learned movement
- Have an understanding of general principles of what type of genetic changes makes vocal learning/spoken language brain pathways specialized, and what happens when those genes are mutated leading to speech disorders.
