Jennifer Oraha, PhD student

In 2024, Jennifer moved from Sydney, Australia to Lund, Sweden to start her PhD studies at the TNU, supervised by Pof. Åsa Petersén. In utilizing novel AAV-vectors and crossbreeding of animal models, Jennifer’s project aims to elucidate the specific hypothalamic circuitries important for the control of metabolism and emotion, with relevance to Huntington’s Disease, Amyotrophic Lateral Sclerosis and Frontal Temporal Dementia. Since 2021, she has been working as a full-time research assistant, wherein her first original research article was published in Natures International Journal of Obesity Journal titled “Sex-specific changes in metabolism during the transition from chow to high-fat diet feeding are abolished in response to dieting in C57BL/6J mice” (Cites 16, FWCI 2.54, 89th percentile).
