Rate My Professor Alfredo Oliveros

Alfredo Oliveros is an Assistant Professor in the Department of Biological Sciences at the University at Buffalo. He earned a BA in Psychology from the University of North Florida, a PhD in Biomedical Sciences specializing in Molecular Pharmacology and Experimental Therapeutics from the Mayo Clinic Graduate School of Biomedical Sciences, and completed postdoctoral research at Rutgers University. His research specializations encompass regenerative neurobiology, neurogenesis, chemotherapy-induced cognitive impairment, neuroimmunology, omics approaches, and behavioral neuroscience.

The Oliveros Lab examines regenerative neurobiology in disease states that impair cognitive function and reward-motivated behavior, with particular emphasis on chemotherapy-induced cognitive impairment, or chemobrain, which detrimentally affects up to 75% of cancer survivors through cognitive and mood dysfunctions, impaired neural stem cell development, and neuroinflammation. Utilizing a multidisciplinary approach, the lab integrates preclinical mouse models, behavioral assays such as the Morris water maze, novel object recognition, elevated plus maze, and 5-choice serial reaction time task for operant conditioning; advanced techniques including RNA sequencing, proteomics, bioinformatic pathway analysis, stereotaxic AAV-Cre viral targeting in specific brain regions, molecular biology methods, immunofluorescence, and confocal microscopy. This enables investigation of molecular mechanisms by which chemotherapies disrupt hippocampal neurogenesis—tracked via colocalized MCM2 and DCX markers in the dentate gyrus—and striatal function, leading to deficits in learning, memory, attention, and emotive behavior. Additional projects probe neuroinflammatory activation of microglia across hippocampus, cortex, and striatum, as well as innate and adaptive immune responses in the meningeal compartment contributing to cognitive decline.
