Kumar Ankit is an Assistant Professor in the School for Engineering of Matter, Transport and Energy at the Arizona State University. He received an Integrated B.Tech.-M.Tech. degree (2010) in Metallurgical Engineering from Indian Institute of Technology, BHU and obtained Ph.D. (2015) in Mechanical Engineering from the Karlsruhe Institute of Technology (KIT), Germany, where he graduated summa cum laude. Following graduation, he was appointed as Group Leader at KIT, where he received an Early-career Investigator grant from the German Research Foundation, centered on computational modeling of microstructural pattern formation in multicomponent steels. Prior to his appointment at ASU, he was a postdoctoral research associate at the Texas A&M University where he worked in the area of modeling and simulations of pattern formation during deposition of multilayered films. Ankit’s research is focused on computational materials science, with an emphasis on phase-field modeling. He is currently interested in deciphering computational pathways to optimally design microstructure processing routes. Focus areas include solidification, solid-state transformations and grain coarsening in multicomponent alloys and geomaterials, electromigration-induced damage, and self-organization in polymers and vapor-deposited films.

My research group specializes in the development and application of mesoscopic, computational modeling techniques and their integration with continuum approaches for both fundamental and applied research in microstructure science and engineering. Our expertise lies in the quantitative phase-field modeling of microstructural evolution in materials. Areas of application include solidification, solid-state transformations and grain coarsening in multicomponent alloys and geomaterials, electromigration-induced damage, and self-organization in polymers and vapor-deposited films.
