Description of Research Expertise

Research Interests:
The functions of small RNAs in fertility, inheritance, and development.

Key words: RNA, sperm, embryogenesis, fertility, epigenetics, microRNAs, epididymis, extracellular vesicles

Research Details:
We are particularly interested in how RNAs present in sperm are capable of transmitting non-genetic information to their progeny, influencing offspring phenotype. This includes, 1) how small RNAs regulate gene expression in the male germline to support spermatogenesis and fertility, 2) how small RNAs are packaged into mature sperm, 3) how RNAs transmitted during fertilization are able to regulate early embryonic gene expression and development, and 4) how this regulation can alter developmental programs to produce a non-genetically inherited phenotype. The lab utilizes a combination of state-of-the-art genomic, molecular biology, and assisted reproduction techniques across multiple model systems including mice, embryonic stem cells, and C. elegans to understand these questions.
