Jonathan Roth, Ph.D., Postdoctoral Fellow
Dr. Jonathan Roth recently completed his Ph.D. in Neuroscience in the Department of Neurology at UAB in Dr. Erik Roberson’s lab, where he studied the role of Tau and its interaction partners in Alzheimer’s disease (AD). He was awarded a National Research Service Award F31 from the National Institute of Aging to fund his research. During his Ph.D., Jonathan was also a teaching assistant for many classes at UAB, completed a Center for Integration of Research, Teaching, and Learning (CIRTL) Practitioner teaching certificate, and published an education manuscript based on his experience.
Jonathan joined Dr. Girish Melkani’s lab studying genetic contributions to circadian dysfunction in AD using Drosophila melanogaster (fruit fly) models of AD. He will test the impact of genetic or environmental circadian rhythm disruption on the onset and severity of AD pathology. Conversely, to restore aspects of circadian rhythm in older flies, he will subject flies to time-restricted feeding (TRF) in which food is provided only during the day. To test the molecular pathways mediating the opposite effects of circadian rhythm dysfunction and TRF on AD pathologies, time-series transcriptomes from these flies will be analyzed to find candidate pathways. The functional significance of these pathways will be tested by expressing the genetic gain of function and loss of function alleles in AD models. Successful completion of this project will provide a deeper molecular understanding of the interaction between circadian rhythm and the genetic risk of AD. Most importantly, this research will assess the efficacy of a behavioral intervention that has a high potential for adoption in humans.
Ruan Moraes, Ph.D., Postdoctoral Fellow
Dr. Ruan Moraes holds a Ph.D. in Human Physiology, with a major in neurophysiology, at the Institute of Biomedical Sciences from the University of São Paulo (Brazil). During his Ph.D. he researched the metabolism of complex B vitamins and bioenergetics in models of neurodegeneration and Alzheimer’s disease. During his Ph.D. he was awarded a fellowship (CAPES-PDSE) at the German Institute of Human Nutrition (DiFE) to conduct part of his experiments. He is constantly interested in nutritional biochemistry and metabolism, and has collaborations in studies involving drug development and pre-clinical tests of metabolic modulator drugs to treat diabetes and fatty liver disease. His experiences also include research on menopause, intermittent fasting, and exercise performance. Ruan joined Melkani’s lab to investigate the role of Lamin (LamC) gene mutations in cardiometabolic and neurodegenerative diseases using Drosophila melanogaster (Fruit fly) models, as well as to investigate the bioenergetic effects of time-restricted feeding and circadian rhythm disruption in models of neuropathologies.
Yiming Guo, MS, GBS, Graduate Student
Yiming is currently researching potential underlying mechanisms of cardiac and intestinal aging under metabolic challenges, and the understanding mechanism underlying TRF-mediated benefits on cardiac and intestinal function. Her other project is linked with lipid storage myopathy and she has generated CRISPR models for understanding the pathophysiological basis of lipid storage myopathy in a Drosophila model.
Christopher Livelo, MS, GBS, Graduate Student
Christopher’s research involves exploring skeletal muscle function as a key metabolic organ and how interventions such as time-restricted feeding (TRF) protect muscle function against metabolic challenges. Additionally, he is also involved in studying the potential role of the microbiome in mediating skeletal muscle function upon TRF intervention.
Farah Abou Daya, MS, GBS, Graduate Student
Farah’s project revolves around identifying the genetic link between insomnia and cardiovascular disease, using human genome studies and fly models. She is modulating Drosophila orthologs of causal human insomnia genes to outline biological pathways linking cardiovascular disease with insomnia. She is also testing if improved sleep through genetic, lifestyle or small-molecule interventions improves cardiovascular function.
