About Me

Email: damien.huzard (at) gmail.com

Hi! I’m Damien Huzard, PhD in behavioral neuroscience.

I’m fascinated by bio-behavioral phenotyping, which is considering and describing organisms in their entirerity. I consider myself a “neuro-physio-behaviorist”. I like doing and trying a lot of stuff, mostly science related.

My main research interests are gravitating around the concepts of Adaptation, Stress, coping strategies, social interactions which are linked to main physiological features such as cardiac regulation and sensory-processing.

I am an advocate for the biobehavioral phenotyping of animal models, pushing for a description over an interpretation of data!

Now, I am focusing on analyzing the skin as (one of) the first interface linking environment and behavioral adaptation.

I am an expert in behavior: protocols and analysis. I’m moderator of TheBehaviourForum
I know a few Python libraries: Pandas, Scipy, Seaborn, statsmodel, Dabest, ipywidget …
I developed one python library (LMT-Widget-Tool) to help non-python-experts analyze live mouse tracker data.
I combine behavioral tests with physiological parameters, such as ECG/HRV and Skin-Nerve recordings.

My ultimate goal is to improve the way preclinical behavioral research could benefit clinical conditions.

Lab Experience

Senior Postdoc

Labs of E. Bourinet and A. François
Affective touch lab link
Uni Montpellier, Inserm, IGF
Montpellier, France July 2021 - May 2024

What if the skin and somatosensory system were involved in social deficits of a mouse model of autism?

I was Studying the effects of Affective Touch on mice:

Analyzing a Shank3-KO mouse model of autism:
- What if sensory deficits at the periphery may be related to reduced sociability?
- Dysregulation of primary somatosensory neurons.
Links with heart rate variability features?
Studying the emergence of social interest and its link with vagal components.
Studying the development of affective touch neurons (C-LTMRs) and their implication on the development of sociability.

Techniques used: Skin-Nerve recordings, Live Mouse Tracker, ECG recordings (HRV analysis), behavioral phenotyping…

Postdoc #1

Jeanneteau Lab
Inserm, IGF
Montpellier, France February 2019 - February 2021

I was studying social behaviors with two mouse models of Autism (Magel2-KO and Cntnap2-KO).

Developed the Social Fear Conditioning protocol and the Live Mouse Tracker system in the laboratory.
Observed higher social fear retention in both mouse models of autism.
Attempted to reduce social fear with positive social interactions (with different social housing conditions)… It only worked in some specific situations.

PhD Candidate

Sandi Lab (LGC)
EPFL, Switzerland March 2014 - June 2018

LGC Lab

I studied the bio-behavioral phenotype of rats with different stress adaptation profiles:

Focused on a model of rats selected for differential adaptation profiles to stress.
Low < Inter < High reaction animals showed different bio-behavioral profiles.
Validated the use of the lines as an effective way to study neurodevelopment disorders related to stress pathways.
Demonstrated that both Low and High lines had abnormal heart rate variability (cardiac susceptibility).
Observed that High line rats had better working memories after aging: “stress helps consolidate memories”, while the Low line rats had impaired learning and deficits in memory reversal: “illustrating negative effects of blunted stress responses”.
Explored the influence of social buffering and social contagion between rats with different ‘personalities’ by housing them together (still under preparation…).

Master Project

Mumby Lab
Concordia University
Montreal, Canada July 2012 - October 2013

CSBN Website

The effects of extrinsic stress on somatic markers and behavior are dependent on animal housing conditions, D. Huzard et al., Physiology and Behavior, 2015

Studied the beneficial effects of Enriched Environments on stressed rats.
Rats were stressed and then housed in enriched environments in social groups (4 males and 2 females).
Observed beneficial effects of the enrichment on the behavioral phenotype of the stressed animals.
