Research Interests

My research interests are in (1) the use of laboratory animal models of psychiatric diseases and symptoms for the evaluation of potential therapeutic approaches, (2) the use of drugs and genetically engineered animals to identify the neurobiological contributors to basic and complex behavioral processes, and (3) the investigation of short- and long-term effects of exposure to psychiatric medications. Dr. Soto also collaborates with Dr. Christopher Morrison ( at the Pennington Biomedical Research Center using behavioral economic demand assessments to measure changes in “motivation” for protein induced by changes in dietary protein and using genetically modified mice to identify the neural substrates that mediate behavioral changes in response to variation in dietary protein. Recently, Dr. Soto has begun advocating for the use of single-case experimental designs in areas outside of behavior analysis, such as behavioral neuroscience, because of the scientific and ethical benefits provided by these designs.
