American professor and academic
Kimani Christopher Toussaint, Jr. is an American engineer who is a professor and senior associate dean in the School of Engineering at Brown University .[1] [2] His research considers the development of quantitative nonlinear optical imaging methods and advanced optical techniques for nanotechnology, and the characterization of plasmonic nanostructure.[3] He is a Fellow of Optica .
Early life and education [ edit ]
Toussaint is from Philadelphia .[4] He became interested in physics as a child.[5] Toussaint studied physics and African American Studies at the University of Pennsylvania , where he met Anthony Garito, a professor who introduced him to optics and engineering.[5] In his physics classes, he was one of the only African American students.[5] He moved to Boston University for his graduate research, where he specialized in electrical engineering. His doctoral research explored quantum ellipsometry of semiconductors.[6] At Boston, he was awarded a Gates Millennium Fellowship , which supported his graduate program.[4]
Research and career [ edit ]
After his PhD, Toussaint was a postdoctoral fellow at the University of Chicago , where he worked on superresolution optical microscopy, optical tweezing of nanoparticles, and polarization control.[7] [8]
Toussaint was appointed to the faculty at the University of Illinois at Urbana-Champaign in 2007.[citation needed ] His research exploits various properties of light, including angular momentum , linear momentum and other polarization degrees of freedom. He is interested in the realization of bioimaging techniques to better understand biological tissue and disease.[9] To this end, he developed an imaging platform that combines second-harmonic generation imaging with confocal microscopy and Mueller matrix polarimetry.[5] Alongside bioimaging, Toussaint has developed nano antennas to exploit near-field optics .[5]
In 2014, Toussaint worked as a Martin Luther King Jr. Visiting associate professor at Massachusetts Institute of Technology and worked with Peter So .[10] In Fall 2019, Toussaint joined the faculty at Brown University , and by 2020 he was made a Senior Associate Dean of the School of Engineering.[11] [12] He leads the Photonics Research of Bio/Nano Environments (PROBE) laboratory[13] and is Senior Associate Dean in the School of Engineering.[14] He is part of the National Science Foundation Engineering Research Center in Cellular Metamaterials.[11]
During the COVID-19 pandemic , it emerged that pulse oximeters were less effective on Black patients. This is because melanin absorbs light, making pulse oximeters overestimate the level of oxygen in a patient's blood.[15] In response, Toussaint started to develop a new, more equitable device.[16] [15] In an interview with Optica, Toussaint said that the pandemic changed his perspective of where his research could have the largest societal impact.[15] [17]
Awards and honors [ edit ]
Toussaint is a Fellow of SPIE [18] and Optica .[5] Other awards and honors include:
Selected publications [ edit ]
His publications[1] [2] [3] include
Application of plasmonic bowtie nanoantenna arrays for optical trapping, stacking, and sorting [25]
The effect of keratoconus on the structural, mechanical, and optical properties of the corne [26]
Nonlinear optical response from arrays of Au bowtie nanoantennas [27]
