Office: N704

​Dr. Oner Celepcikay is an adjunct faculty at the University of Houston-Downtown Department of Computer Science & Engineering Technology. He also teaches for Texas A&M Commerce. His main teaching and research fields are Data Science, Data Mining, Machine Learning and Regression Analysis. He previously taught at University of Phoenix and University of Houston. He received his bachelor's degree in Electrical Engineering from Istanbul University in Istanbul, Turkey, and his master's and doctorate degrees in Computer Science from the University of Houston. Dr. Celepcikay is a published researcher doing research in spatial data mining, cluster analysis, regional regression analysis, and big data analytics. He worked at the University of Houston Educational Technology Outreach Department from 2000 to 2007, and is a member of the Institute of Electrical & Electronics Engineers, the world's largest professional association dedicated to advancing technological innovation and excellence. Dr. Celepcikay is one of the founding members and current Chairman of the Board of Harmony Public Schools, the largest charter school system in Texas with a STEM focus and 43 campuses in Texas. He also sits at he Board of Directors of the Region 4 Education Service Center which serves a seven-county area composed of 50 public school districts and 45 public charter schools, representing more than 1.1 million students and 1,500 campuses.

Academic Interest

My main research interests lie in the field of knowledge discovery and data mining, with applications to geosciences, environmental sciences, and astronomy. My research focuses on designing and implementing an integrated framework to systematically discover regional knowledge in spatial datasets. We work on developing methods to uncover hidden correlation patterns and developing regional regression tools that capture spatially varying relationships among attributes. We developed a regional regression framework, called REG^2, that discovers regional regression functions that are associated with contiguous areas in the subspace of the spatial attributes which we call regions.

I teach data mining, big data analytics, database management systems, object-oriented analysis and design, web programming, programming languages. One important aspect of my teaching philosophy is that students must ultimately take responsibility for their own learning. I try to make my classes very interactive and encourage students to earn participation points by asking questions or solving in-class exercises. Students can always expect that I am approachable and available to answer questions, and will happily invest in their academic success.
