Happy holidays from the Palmer Lab!
Palmer Lab members enjoyed time together at the annual holiday party on December 18, 2025. Food, fun…and rats!

The manuscript titled “Beyond Mendel: a call to revisit the genotype-phenotype map through new experimental paradigms” was accepted for publication in Genetics.
The 11th annual retreat for the NIDA Center of Excellence for Genetics, Genomics, and Epigenetics of Substance Use Disorders in Outbred Rats was held on Thursday, November 20, 2025 at the University of California San Diego.
Thank you to all who attended in person and remotely, and thank you to the session speakers and poster presenters! We hope you found the talks and discussions informative and made connections with new HS rats colleagues.
Palmer Lab members attended SfN/Neuroscience 2025 at the San Diego Convention Center, November 16 – 19 2025.
Did you visit us at the RATTACA booth to support the HS rats P30 center?
The 22nd Annual Meeting of the Complex Trait Community (CTC) was held October 21 to 24, 2025 at the Centre for Genomic Regulation (CRG) in Barcelona, Spain in collaboration with the Rat Genomics Community.
Palmer Lab members Dr. Palmer, Dr. Oksana Polesskaya, Dr. Thiago Sanches, Dr. Montana Lara, Dr. Zachary Tatom, and Apurva Chitre attended and presented in person.

[This is a renewal of “The Genetic Basis of Opioid Dependence Vulnerability in a Rodent Model” (U01DA045300), awarded to Dr. Peter Kalivas, Medical University of South Carolina, from 2018-2024.]
Congratulations!
A new R01 grant from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) was awarded to Dr. Lieselot Carrette, with Dr. Abraham Palmer as co-investigator.
The grant is titled “Magnetic Resonance Imaging of Outbred Rats with Variable Vulnerability to Compulsive Alcohol Use” and it will start September 20, 2025 and end on August 31, 2029.
Congratulations!
Dr. Brittany Leger successfully defended her thesis titled “Utilizing a network biology framework to integrate GWAS signal across species, variants, and traits” on September 15, 2025.
Congratulations, Dr. Leger!
