Dr. Orlin D. Velev received M.Sc. and Ph.D. degrees from the University of Sofia, Bulgaria, while also spending one year as a researcher in Nagayama Protein Array Project in Japan. After graduating in 1996, Velev accepted a postdoctoral position with the Department of Chemical Engineering, University of Delaware. He initiated an innovative program in colloidal assembly and nanomaterials and was promoted to research faculty in 1998. In 2001 formed his new research group in the Department of Chemical and Biomolecular Engineering, North Carolina State University, where he was promoted to an Associate Professor with tenure in 2006, to full professor in 2008, to chaired professor in 2009 and to distinguished professor in 2018. He has contributed more than 230 publications, which have been cited more than 29,000 times, and has presented more than 290 invited presentations at major conferences and at universities and companies. His awards include among others NSF Career, Langmuir Lecturer, AIChE Acrivos Professional Progress, Camille Dreyfus Teacher-Scholar, Sigma Xi, NC State Alcoa Distinguished Engineering Research, NC State Alumni Distinguished Undergraduate Professor, NC State Innovator of the Year, Springer Colloid and Polymer Science Lecture Award. Velev has been elected to an ACS Fellow and MRS Fellow. He has served as member of the Editorial Advisory Boards of Langmuir, Chem. Mater., Biomicrofluidics and Particle and as Section Editor of Curr. Opin. Colloid Interface Sci. Velev has established a record of innovative research in the area of colloids and nanostructures with electrical and photonic functionality, biosensors, microfluidics and nanomanufacturing. He has been the first to synthesize "inverse opals", one of the most widely studied types of photonic materials today. Velev has also pioneered techniques for making novel nanoparticle materials, Janus particles, rod-like particles, and responsive foams. Technologies based on his research have formed the basis of two Research Triangle Area startup companies. He has been an advocate of incorporating the latest achievements in the areas of nanoscience and nanotechnology in the engineering curriculum.
