  • Ph.D. (Animal and Dairy Science), University of Georgia, 2015
  • MS (Animal Science/Breeding and Genetics), Federal University of Minas Gerais (Brazil), 2012
  • Doctor of Veterinary Medicine, Federal University of Bahia (Brazil), 2009
After receiving his Ph.D. in 2015, Dr. Fragomeni completed two and a half years of postdoctoral training at the University of Georgia, under the mentorship of Dr. Ignacy Misztal. In 2018, Dr. Fragomeni joined the University of Connecticut as an Assistant Professor in the department of Animal Science.


Area of Interest

My current research focuses on using genomic information in predicting animals' performance, and implementing this information for optimum selection and breeding decisions. Our lab's main goal is to use genomic selection to improve novel and complex traits such as disease resistance, environmental robustness, survival, among others; we also aim to dissect the underlying genetics of such traits. Additionally, our lab utilizes various genomic tools to study the structure of livestock populations.

Research Interests

  • Methods for genetic and genomic evaluation in livestock animals.
  • Use of genetic and genomic tools to mitigate environmental impact in livestock.
  • Genotype by environment interaction.
  • Selection for novel traits, such as disease resistance, heat stress robustness, resilience.
  • Animal breeding and sustainability.
  • Use of high throughput data in genomic evaluation.
