Biography
Dr. Dineshkumar Sengottuvelu is a Research Assistant Professor at the Center for Graphene Research and Innovation at the University of Mississippi. He received his Ph.D. in Chemistry from Bharathiar University, India, where his doctoral research focused on the synthesis and characterization of conjugated polymers and their optical, electrical, and thermal properties. He subsequently completed postdoctoral research at Birla Institute of Technology and Science (BITS Pilani), India, and Mississippi State University, where he investigated aggregation‑induced emission materials, carbon quantum dots, and sustainable polymer systems for optoelectronic and energy‑related applications. Dr. Sengottuvelu’s research centers on the development of low‑dimensional materials, including graphene, transition metal dichalcogenides, and quantum dots, with particular emphasis on chemical vapor deposition synthesis, photophysical characterization, and structure–property relationships. His current work focuses on 0D–2D and 2D–2D heterostructure materials and their integration into optoelectronic and energy‑efficient electronic devices such as photodetectors and field‑effect transistors. He is a Co‑Principal Investigator on a U.S. Department of Energy EPSCoR award supporting research on heterogeneous integration of 2D–3D materials for next‑generation electronics. Dr. Sengottuvelu has authored numerous peer‑reviewed publications in high‑impact journals, including ACS Applied Materials & Interfaces, ACS Nano Materials, Macromolecules, and ChemSusChem. In addition to his research activities, he is actively involved in mentoring graduate and undergraduate students, engaging in K–12 STEM outreach, and contributing to the scientific community through editorial board service, guest editorships, and peer review for leading materials and chemistry journals.
