Research in the Jarome lab is focused on elucidating the cellular and molecular mechanisms of memory formation and storage, with an emphasis on understanding how stressful or traumatic events alters brain chemistry that drives future behavioral and physiological responses. These future responses are often maladaptive, resulting in a variety health concerns, and can be passed to future generations through “epigenetic” mechanisms. The lab focuses on mechanisms of initial memory storage and those involved in memory modification following retrieval (recall). Currently, the lab has several areas of interest:

  • An epigenetic role for the ubiquitin-proteasome system in fear memory formation
  • Epigenetic mechanisms of fear memory modification following retrieval

To address these topics, we combine a traditional rodent behavioral paradigm (Pavlovian fear conditioning) with a variety of traditional and modern molecular biology and neuroscience techniques. This includes using in vivo pharmacology, siRNA-mediated gene knockdown, and CRIPSR-dCas9 transcriptional editing to manipulate specific genes and/or cellular processes during learning or memory retrieval and analyzing the effects of these manipulations on the cellular memory storage process using western blotting, qRT-PCR, chromatin immunoprecipitation, methylated DNA immunoprecipitation, bisulfite sequencing and other molecular biology methods. Students who join the lab will have the opportunity to learn these techniques and, as they advance, will have the opportunity to take projects in new directions or initiate new topics.

Prospective students interested in joining the lab should contact Dr. Jarome by email.
