Principal Investigator

Jenny Chen, PhD

My research is inspired by the remarkable fact that a simple four-letter code generates the immense diversity we see across the tree of life.

I am passionate about developing high-throughput sequencing and computational approaches to understand the molecular mechanisms that give rise to this diversity, with a current focus on investigating innate animal behaviors.

I received my PhD in Bioinformatics and Integrative Genomics from MIT, where I was advised by Aviv Regev. I then became a Harvard Data Science Fellow and NIH K99/R00 Fellow, and worked in collaboration with Hopi Hoekstra and Sean Eddy to study the genetic basis of monogamy-related behaviors in Peromyscus deer mice.

Research

Our research aims to investigate the evolution of innate social behaviors and discover novel neuropeptides.

To do so, we take advantage of evolutionary patterns of innate animal behaviors, and use comparative genomics approaches combined with techniques from neurogenetics and behavioral neuroscience. We work with non-traditional mammalian model organisms, like closely related Peromyscus deer mouse species that have evolved a variety of innate behaviors despite their high degree of shared genetic similarity.

Genetic basis of monogamy-related behaviors

Monogamy has independently evolved multiple times across the rodent lineage, and co-evolves with a suite of behaviors including biparental care, increased territoriality, and selective aggression. What genes encode these behaviors, and how do they evolve to produce differences across species? To answer this, we use single-cell multiomics to characterize how hypothalamic neurons are evolving across monogamous and promiscuous rodent species, paired with neurogenetic approaches to identify key genetic changes driving this behavioral evolution.

Neuropeptide discovery

Neuropeptides are critical signaling molecules that regulate diverse biological processes, yet some may remain undiscovered due to their small size and low abundance. We develop computational methods to discover novel neuropeptides and generate transgenic rodent models to investigate their function.

How to Join

We are looking for curious, collaborative people interested in working at the interface of genomics, evolution, and neuroscience. Those with backgrounds in either computational or experimental biology are all welcome. The lab is based at EMBL Rome, in Monterotondo, Italy — about 20 minutes north of Rome.

Prospective graduate students: I accept graduate students through the EMBL International PhD Programme.

Prospective postdocs: send a brief description of your research interests and how they connect to the lab, along with your CV to jennifer.chen @ embl.it.
