Dr. Rijal is an Assistant Professor at Lab. Sciences, Public Health & Nutrition Science (MLSPHNS) at Tarleton State University (TSU). He received his Ph.D. in Dentistry with majors in Pathology and Regenerative Biology from Kyungpook National University, South Korea under the supervision of Professor Dr. Hong-In Shin. After a brief stint as a postdoc (2013) at POSTECH, South Korea, he joined Elson S. Floyd College of Medicine, WSU Spokane as a Research Associate (2014). In addition, he had worked as a scientist at Department of Bioengineering, University of Texas at Dallas (UTD) before being appointed to MLSPHNS at TSU in 2020. Dr. Rijal has made scholarly contributions to cancer research and biomedical engineering. He is also serving as an editorial board member and as a reviewer of various peer-reviewed journals. His research has been published in various peer-reviewed journals. His current research at MLSPHNS is primarily focused on identifying the mechanisms of cancer tissue initiation and growth using innovative native mimicking 3D systems. The multi-cell-guided microenvironment is created that supports the release of signaling factors, similar to what cells do in native tissue. His second research priority is to generate fundamental native-like 3D cancer scaffolds that help preclinical screenings of anti-cancer drugs in the lab, providing the suggestion either to go for the re-efficacy optimization of anti-cancer drugs or for clinical trials.
