Special Recognition in Science Education
My research is focused on the basic biology of the nervous system and is currently exploring chronic pain.
Since the 1980s, I have explored the development of nerve cells in the fruit fly eye. Among other things, we have found that the RUNX1 transcription factor, LOZENGE, initially influence cells with undetermined fates to choose survival over death. We have also found that LOZENGE proteins contribute to helping a cell choose a specific fate. We have investigated what genes regulate lozenge and in turn, what LOZENGE protein specifically regulates during axon growth and guidance. Our research uses a combination of confocal microscopy techniques as well as quantitative reverse transcription PCR analysis of mRNA expression among other approaches.
New research directions include the analysis of TRP (calcium channel) in the context of a rat chronic pain model. The extensive family of TRP related proteins are intimately involved in pain physiology. As Co-Director of the Chronic Pain Research Consortium (http://www.duq.edu/pain), I am collaborating with Dr. Jelena Janjc (Mylan School of Pharmacy). We are using small animal imaging to co-localize the immune system response to chronic pain and changes in TRP expression through the use of theranostic nanoparticles. We can visualize changes in neuroinflammation in live animals and also use the nanoparticles as a targeted drug delivery mechanism.
Partnerships in Education
My research creates new multimedia learning resources that focus on fundamental principles of science and health literacy, and then explores how people learn from these new resources.
As Director of the Partnership in Education I strive to create a strong and accessible scientific dialogue between the research community and the general public and classrooms. To achieve this, I create informal science education pieces for use in museums including planetariums shows, exhibits, interactive media and supporting teacher resource materials (www.sepa.duq.edu). Research evaluates how effective the new learning tools are as well as how people learn. Topics have included tissue engineering, regenerative medicine, and the fundamental principles of evolution (www.sepa.duq.edu/darwin). Collaborative partners have included the Carnegie Science Center, Carnegie Museum of Natural History, Pittsburgh Zoo & PPG Aquarium, Phipps Conservatory & Botanical Gardens, The National Aviary, The Children's Museum of Pittsburgh, Carnegie Library of Pittsburgh, Pittsburgh Public School, and American Philosophical Society Museum-Philadelphia.
I have also created a children's television show called Scientastic! (www.ScientasticTV.com). Scientastic has been broadcast on public television stations nationwide. A companion App called Powers of Minus Ten-Bones is available from iTunes.
Project funding has come from Science Education Partnership Awards from the National Institutes of Health, and from the US Department of Education, The Pittsburgh Foundation, the John Templeton Foundation, and UPMC Health Plan, among others.

Dr. John Archie Pollock is currently a Full Professor of Biological Sciences at Duquesne University. Dr. Pollock holds appointments as Visiting Professor with the Entertainment Technology Center, jointly managed by Carnegie Mellon University's College of Fine Arts and School of Computer Science. Dr. Pollock is also an Affiliated Faculty with the McGowan Institute for Regenerative Medicine, University of Pittsburgh and UPMC.
Dr. Pollock is an educator who teaches courses in his expertise including neuroscience, microscopy, molecular and cellular biology. His outreach teaching has included working with informal science education in museums and for broadcast television. Currently, he also participates in weekly activities with young learners (4 -7 year olds) and 5th - 7th grades.
As a scientist, Dr. Pollock has spent over 25 years as a principal investigator directing a continuously funded research program in basic science investigating the development of the nervous system. He is also studying chronic pain and the changes in gene expression that are associated with it. He received his Bachelor of Science in physics and also completed a major in philosophy at Syracuse University. He then earned a Masters of Science in physics, as well as his Doctor of Philosophy in biophysics, also from Syracuse University. In order to study in the laboratory of Prof. Seymour Benzer, a pioneer in neuro-genetic and behavioral research, Dr. Pollock moved to Caltech in Pasadena, California. From Caltech, he moved to Carnegie Mellon University to serve as Assistant and then Associate Professor of Biology for 12 years before joining Duquesne University in 2001.
Dr. Pollock is co-director and partnering principal investigator for the Chronic Pain Research Consortium at Duquesne University. This research collaborative is engaging faculty distributed between several colleges and schools at Duquesne University to focus on the study of chronic pain in relationship to regenerative medicine. In addition to conducting research and teaching, Dr. Pollock has served as founding director for the Partnership in Education, which produces multimedia based informal science education projects that are artistically rich STEM learning resources including videos, TV shows, Apps, videogames and teaching resources for young people and the general public. The funding for this work has come from three separate Science Education Partnership Awards from the National Institutes of Health, which have provided support from 2000-2019. Additional support for science education has come from the US Department of Education, The Pittsburgh Foundation, UPMC Health Plan, and The John Templeton Foundation, among others.
Honors and awards include: Samuel and Emma Winters Foundation Research Award, James A. Shannon Director's Award from the National Institutes of Health, Basil O'Connor Starter Scholar Research Award from the March of Dimes Birth Defects Foundation, Visiting Scholar Award from the University of Melbourne, Melbourne Australia, a Grass Foundation Traveling Lecturer for the Society for Neuroscience.
Duquesne University recently recognized Dr. Pollock for the significant and consistent funding that he has generated and awarded him induction into the Office of Research Hall of Fame 2010. In recognition for work in science education, Dr. Pollock was awarded the Carnegie Science Award, Special Achievement in Education 2011.
In 2013, Dr Pollock was recipient of the Bayer School of Natural and Environmental Sciences Award for Excellence in Teaching, in recognition of outstanding instruction provided. Later that same year, Dr. Pollock was honored with Duquesne University President's Award for Excellence in Teaching.
In 2014, the Dr. Pollock, along with Dr. Jelena Janjic, shared the inaugural Provost's Interdisciplinary Research Consortia Grant, which provides University funding for interdisciplinary research and scholarship for the Chronic Pain Research Consortium.
