Dr. Kolber serves as an Associate Professor in the Department of Biological Sciences and the Research and Education Coordinator for the Chronic Pain Research Consortium. Dr. Kolber came to Duquesne in 2011 from Washington University in St. Louis. Dr. Kolber has over 15 years experience doing neuroscience research.
His graduate work with Dr. Louis Muglia, M.D., Ph.D. looked at the role of the endocrine stress response in the modulation of stress adaptation, depression, and anxiety. His post-doctoral work with Dr. Robert Gereau IV, Ph.D. focused on understanding the role of the amygdala in the modulation of acute and chronic pain. Dr. Kolber also has extensive experience teaching at the undergraduate and graduate level. His teaching interests focus on teaching neuroscience, endocrinology, physiology, and in utilizing innovative teaching techniques in the classroom.
In the U.S., more than 115 million adults suffer from chronic pain. Often, successful management of chronic pain involves the treatment of other conditions such as depression and anxiety disorders. In the Kolber lad, we try to understand the common mechanisms of chronic pain and psychiatric illness. This is done by integrating cutting-edge behavioral, pharmacological, electrophysiological, and molecular techniques to understand the mechanisms of stress and pain.
Most of our work is focused on studying the amygdala, which is a small structure in the brain involved in processing stressful stimuli, modulating reactions to a stressor, and modulating pain responses. Depending on the emotional state of an organism, activation of the amygdala can either increase or decrease pain. We are trying to understand the molecular and cellular components of this processing. The precise types of pain that we are interested in understanding include disorders with a clear connection to stress (e.g. fibromyalgia) as well as those that are less commonly associated with emotional dysregulation (e.g. painful bladder syndrome/interstitial cystitis).
An additional focus in the lab is on identifying novel therapies for pain and depression. This includes basic science drug discovery of novel pharmaceuticals from nature and modifications of existing drugs. These projects involve extensive collaborations at Duquesne University (e.g. drug discovery from the ocean with Dr. Kevin Tidgewell, Pharmacy), nationally (e.g. drug discovery utilizing polymers of existing drugs to extend analgesic effects with Dr. Saadyah Averick (Allegheny General), Dr. Lei Yu (Rutgers), Dr. Kathryn Uhrich (UC Riverside)), and internationally (e.g. drug discovery from terrestrial plants with Dr. Telesphore Nguelefack (University Dschang)).
Approaches used in the lab include behavioral tests (e.g. nociceptive tests, anxiety tests, depression tests, learning and memory tasks), physiology (e.g. in vivo recording from the brain, EMG recording during peripheral stimulation), optogenetics, genetic manipulation (e.g. disrupting or activating genes using viral constructs), and molecular/cellular techniques (e.g. PCR, RT-PCR, immunohistochemistry, Western analysis, cell culture, and cloning).
Trainees working in the basic science lab receive a broad-based training in behavior, neuroanatomy, surgical techniques, and molecular biology. This training regiment provides a strong foundation for future success in research and medicine.
In the Kolber lab, we are interested in the application of our basic science mechanistic studies to the human condition. Our translational research is focused on understanding and applying non-pharmacological treatments in chronic pain. These studies stem from our animal studies of physical exercise for treating pain and the numerous studies showing that physical exercise is a valuable integrative therapy in treating complex pain in human patients.
We study the impact of exercise dose in modulating baseline pain responses in healthy human participants and the therapeutic interaction between physical exercise and mindfulness meditation in treating chronic low back pain. These studies involve critical collaborations at Duquesne University (Dr. Matthew Kostek and Dr. Kimberly Szucs, Rangos) and in the Pittsburgh region (Dr. Eric Helm and Dr. Natalia Morone (University of Pittsburgh)).
Techniques in these studies involve human quantitative sensory testing, psychophysical testing, and qualitative assessment of pain.
Trainees working in the clinical research space receive a broad-based training in clinical trial management, human studies ethics, human pain testing, and translational research. This training regiment provides a strong foundation for future success in research and medicine.
