Current Research:

   Dr. Steele's collective past biomedical research spans a wide gamut of topics including: the development and application of molecular screening methods for rapid identification of novel genetic mutations resulting in galactosemia in humans, the molecular genetics of ocular lens proteins and mutations in the genes encoding them that result in loss of vision due to cataract formation, the molecular expression and physiological function and inter-connectivity of retinal neurons and glia in both healthy and stressed or diseased retina, microscopic imaging and quantification of the intracellular calcium dynamics of the presynaptic terminals of intact isolated vertebrate retinal photoreceptors, and the consequences of stroke on retinal expression, structure, and function. Dr. Steele's research has been published in top tier peer-reviewed journals, and continuous and current citations by researchers beyond his immediate collaborators in the fields of study confirm the significant contributions of his work to their respective fields of scientific inquiry.
   After a successful period of active contribution to biomedical research, Dr. Steele has now shifted his focus to the preparation of the next generation of diverse STEM talent. To this end, he serves as author and PI of the NSF-funded Strategies for Transforming Access to Research and Scholarship-1 (STARS-1) Program (https://www.nsf.gov/awardsearch/showAward?AWD_ID=1154218&HistoricalAwards=false) and co-author and co-PI on the NSF-funded science education research grant entitled "Impacts of the Concept Mapping Strategy in Introductory Biology Courses on Learning and Retention of Underrepresented STEM Students" (https://www.nsf.gov/awardsearch/showAward?AWD_ID=1623215&HistoricalAwards=false). These synergistic projects have the shared goals of: 1) informing our present understanding of aspects of learning and student development that contribute to success of underrepresented students in STEM-related disciplines, in the classroom and beyond; and 2) increasing the quality and capacity of STEM-related pipelines for underrepresented students to increase the overall diversity and quality of STEM-related graduate and professional programs and workforces.
