Professor

Associate Professor, Kimani C. Toussaint, Jr.

Kimani C. Toussaint, Jr. earned his B.A. from the University of Pennsylvania in 1996, and M.S. and Ph.D. degrees in Electrical Engineering from Boston University in 1999 and 2004, respectively. His dissertation work focused on using polarization-entangled photons to probe the optical properties of materials. Prior to starting at Illinois, Toussaint was an NSF Minority Postdoctoral Fellow in Biology at the University of Chicago, where he worked on interference microscopy, exotic polarization states, and optical trapping. In 2006, he was one of 100 top American scientists in the United States (under 45) to be selected for the National Academy of Science's 18th Annual Kavli Frontiers of Science Symposium.

Dr. Toussaint joined the Department of Mechanical Science and Engineering at the University of Illinois, Urbana-Champaign in August 2007, and became an affiliate in the Department of Electrical and Computer Engineering, and an affiliate in the Bioengineering Department, in October 2007, and March 2008, respectively. His group pursues interdisciplinary research in optical physics and engineering that has applications in many disciplines, including biology and chemistry. Currently, he is developing an advanced optical microscopy platform for characterizing and manipulating both nano- and biological systems.

 

Postdoctoral Researchers

Hao Chen

Hao received his M.S. and Ph.D. degrees in Department of Physics from Nanjing University, China in 2009 and 2012, respectively. He joined the PROBE Lab in Spring 2013 as a postdoc. His research interest mainly focus on the application of unconventional polarization, optical manipulation, microscopy, optical angular momentum and sigular optics.

 Gopala Krishna Inavalli

Is a Post doctorial research associate who joined the PROBE lab in spring 2013, his research interests mainly focus on Bio imaging using tightly focused vector beams, polarization second harmonic generation and linear susceptibility. Also, he is interested in dynamical behavior of isolated polarization singularities and angular momentum.

V.V.G. Krishna Inavalli received his M.Sc degree in physics from Andhra University 2006 and PhD degree in Singular Optics from Hyderabad Central University in 2012. His PhD work carried in the Beam Optics and Applications Group on the generation and characterization of Optical vector, vortex and isolated polarization singularities using a two mode step-index fiber and their applications. Generated beams are characterized using different techniques such as analyzer rotation, polarization interferometric method, complex Stokes parameter method and the state of polarization (SOP) map at each point in the output beam cross section.
