Dr. Covelo is a neuroscientist interested in motivation. In his laboratory, Dr. Covelo uses non-human animal models to study the neurobiological mechanisms underlying motivated behaviors (v. g. feeding, drinking, sex, drug intake, etc.). His main interest is the study of brain circuits that control overeating or non-homeostatic feeding. Before joining the University of Wisconsin-Parkside, Dr. Covelo was a researcher at the Psychiatric Institute studying schizophrenia and obtained a Ph.D. in Neuroscience from the University of Illinois at Chicago studying the neural control of non-homeostatic feeding. After defending his doctoral dissertation, Dr. Covelo completed a postdoctoral fellowship in the Neuroscience Institute at the University of Michigan studying pre-clinical models of addiction. Finally, Dr. Covelo moved to Wisconsin, taught biology and psychology courses at Marquette University, and joined the department of psychology at Parkside in 2019.
Areas of Expertise
- Motivated behaviors
- Neurobiology of mental disorders
- Neurobiology of addiction
- Neurobiology of eating and obesity
- Cortico-thalamic-striatal-hypothalamic circuits
Teaching Interests
Dr. Covelo teaches courses in behavioral neuroscience where students explore the relationship between brain function and behavior. His interests also include the neurobiology of mental disorders, emphasizing the underlying neural mechanisms of conditions such as anxiety, depression, and schizophrenia. Additionally, Dr. Covelo enjoys teaching psychopharmacology, providing students with a basic understanding of how drugs influence the brain and behavior in clinical and non-clinical settings.
Research Interests
My main scientific interest is the study of how the brain controls motivated behaviors (e.g., food, water, sex, drug seeking, and consumption).
To address my main interest, I am studying how a brain circuit composed of the nucleus accumbens, ventral pallidum, and hypothalamic nuclei regulates feeding. Specifically, feeding in excess of the organism’s homeostatic needs or overeating. In this program, I work with a group of undergraduate students. In the laboratory, we use preclinical nonhuman animal models to explore how pharmacological and chemogenetic manipulations of brain cells within this brain circuit lead to dysregulated feeding.
I believe that this line of research can potentially lead to novel therapeutic methods aimed at treating overeating and other disorders of dysfunctional feeding. And inform our understanding of disorders characterized by dysfunctional motivation.
Consulting Interests
Dr. Covelo is an expert in behavioral neuroscience available for consulting on grant proposals, research methodologies, designing behavioral models, and advising on data interpretation.
