Research Interests:

Our research program uses genetics and genomics tools to study phenotypic traits and diseases in companion animal species, with particular focus on horses and camelids. The goal of our research is to use a multidisciplinary and collaborative approach to study the genetic basis of biologically and economically important traits in these species, as well as to elucidate the genetic mechanisms of inherited diseases.

Equine Research Projects:

Our equine research studies are conducted in collaboration with Dr. Rebecca Bellone, and focus on investigating the genetic basis of coat color, conformation and performance phenotypes in various breeds. Our team is also interested in studying genetic diversity within and among horse breeds, and how modern breeding practices have shaped the genome of different breeds.

Camelid Research Projects:Llama

Our camelid research program involves a multidisciplinary and collaborative team of researchers and veterinarians, with the goal of studying coat color and disease genetics in alpacas and llamas. Currently, we are investigating the genetic basis of congenital sensorineural deafness in blue-eyed white alpacas, as well as various pigmentation phenotypes in both alpacas and llamas. Our team is also invested in helping the camelid genomics community to improve the alpaca genome assembly and annotation.

If you are interested in joining Dr. Avila’s team, or would like to contribute to a research project, please contact Dr. Avila.

 

Current Team Members:

Elizabeth Esdaile

Elizabeth Esdaile is a Masters student in the Animal Biology Graduate group. She is currently studying the genetics of several coat color traits in horses as well as genetic diversity within and among horse breeds under the mentorship of Dr. Bellone and Dr. Avila.


Rayann Eaves

Rayann Eaves is an Animal Science undergraduate student at UC Davis. She joined the Bellone/Avila laboratory during her junior year, and is currently working on various coat color and disease genetics projects in camelids.
