Now that the first few weeks of school are over, many have met the new faculty that are roaming the halls of the STEM College. We may not know them by name just yet, but we recognize that they are new faces. Some of the new faculty were brought in to help expand several areas of the STEM College, including the Ph.D. program in Materials Science and the new natural gas minor.
Let us now introduce the newest members of the faculty!
Dr. Snjezana Balaz
Dr. Snjezana Balaz earned her bachelor’s degree in Physics from Northland College in Ashland, WI in 2001, her Master of Science degree in Physics, as well as her PhD in Chemical and Materials Engineering from the University of Nebraska-Lincoln in 2005 and 2007, respectively. She has since worked at the University of California at Riverside and The Ohio State University. Dr. Balaz has extensive experience and publications in the field of surface science. Her research has focused on the structure of surfaces of thin films, semiconductors, and nanoclusters. Among her accomplishments, she is the first to show that boron carbide, a novel semiconductor, makes an effective neutron voltaic and photovoltaic diode that has been made into a solid-state neutron detector for Homeland Security. She investigated the tantalum oxynitride series ATaO2N (A = Ca, Sr, Ba) and RTaON2 (R = La, Pr), promising candidates for photocatalytic splitting of water under illumination by visible light. She is also the first to reveal the electronic properties of perovskite oxides heterojunctions that are grown and characterized in situ. Dr. Balaz is currently studying organic interfaces using surface science techniques to better understand their electronic and chemical characteristics. Dr. Balaz is passionate about the STEM fields and in creating strong scientists and thinkers.

Her future research interests are focused on combining her coatings experience with her corrosion experience in an effort to reduce and control microbially assisted corrosion in the oil and gas industry. Dr. Martin also has experience teaching a multitude of chemical engineering classes at the freshman, junior, senior, and graduate level.
Dr. Robin Mattheus
Dr. Robin Mattheus graduated from the UNC Department of Marine Sciences in 2009 with his PhD. His graduate work focused on shallow coastal stratigraphy and sediment-transport dynamics through coastal environments of North Carolina. He received both his bachelor’s and master’s degrees in Geology from the University of Alabama in 2003 and 2006, respectively.
Following graduate school, Dr. Mattheus held a position as Visiting Assistant Professor at Hamilton College, in New York, for one and a half years and, most recently, a two-year visiting position at YSU in the Department of Geological and Environmental Sciences. He has had the opportunity to teach a broad spectrum of Earth Science courses over the last 4 years, including Sedimentology/Stratigraphy, Geomorphology, Geohazards, Oceanography, and River Environments, among others.
Dr. Mattheus’s general research interests are in coastal geology, sedimentology, and fluvial geomorphology. He is particularly interested in how coastal environments evolve in response to changes in sea level, climate, and human impacts.
Dr. Donald Priour
Donald Priour has joined the YSU Department of Physics & Astronomy this fall as a tenure track assistant professor. Donald is a native Texan who received his undergraduate degree from Rice University and his doctoral degree from Princeton University. Donald specializes in theoretical condensed matter physics. Donald’s teaching interests at YSU include introductory physics, classical mechanics, modern physics, and materials science at the doctoral level. He is also interested in finding ways to teach computational methods with an emphasis on programming environments, which led to transferable industrially relevant skills. Much of Donald’s research has a computational element, and the presence of disorder is a major theme. Donald has studied magnetic semiconductors, percolation physics in continuum systems, and charge transport in amorphous media. Recently, his research interests have also included thermodynamic phases in hard-core models for liquid crystals and band gaps in patterned photonic crystals.
Dr. Suresh Sharma
Originally, Suresh Sharma is from Nepal. He received his bachelor’s degree in Civil Engineering and his master’s degree in Water Resources Engineering (Civil) from Tribhuwan University, Nepal.
