Antal I. "Tony" Jákli (born 3 October 1958) is a Hungarian-American physicist and professor of Chemical Physics at Kent State University. He is known for his work with bent-core,[1][2] flexoelectric, and ferroelectric liquid crystals.

Education and Career[edit]

Jákli received a Master of Science in 1983 and later a Ph.D. in 1986 in Physics from Eötvös Loránd University in Budapest, Hungary.[3] After postdoctoral fellowships with Alfred Saupe at Kent State University from 1989 to 1992 and at the Max Planck Institute in Halle, Germany, from 1993 to 1995, he became a research fellow at the Research Institute for Solid State Physics in Budapest. He was later awarded a D.Sc. from the Hungarian Academy of Sciences in 2000.

He moved to the United States in 1999 to join the Liquid Crystal Institute at Kent State University as a research fellow. He became an assistant professor there in 2004, receiving tenure in 2007 and a promotion to full professorship in 2012.

Research[edit]

His current research interests include studies of bent-core and other liquid crystals with reduced symmetry, electrospun responsive fibers and mats, flexoelectricity and piezoelectricity, small-scale rheometry, blue phases, and surface interactions of liquid crystals.
