Explore What is Possible

Teng-Leong Chew


Leong became the director of the Center for Advanced Microscopy at Feinberg School of Medicine, Northwestern University in 2002, and led the facility to be recognized as one of the few selected Nikon Imaging Centers in the world. At the same time, his lab began devising methods to engineer three-dimensional, lumenized vascular network capable of dynamic signaling read-out. This approach ultimately allowed Leong and his team to dissect the regulatory signals in the opposing endothelial cells during cancer diapedesis. In 2009, he was further appointed to the position of Director for University Imaging Resources at Northwestern, overseeing the institutional strategy in building integrated imaging infrastructure across all seven imaging centers within the university.

Leong joined Janelia in 2014 to serve as the Director for the Advanced Imaging Center. Here, he leads the effort in building the unique collaborative imaging center that serves as the gateway through which the wider scientific world can access Janelia’s cutting-edge microscopy capabilities.

He finally moved to the Stowers Institute for Medical Research where he discovered how immune cells control organ regeneration in zebrafish. At Janelia, Nicolas will use his problem solving skills and microscopy knowledge to help researchers tackling some of the most challenging questions in biology.


Michael DeSantis

Research Specialist

Michael received a B.S. in physics and biophysics from Brandeis University before earning A.M. and Ph.D. degrees in physics from Washington University in St. Louis. As a graduate student, he developed image deconvolution techniques and particle tracking algorithms for single molecule fluorescence studies with high spatiotemporal resolution. Afterwards, he pursued postdoctoral research at the University of Michigan studying the real-time infection of individually characterized HIV-1 virions using a novel platform that combined optical trapping, two-photon excitation microscopy, and back-focal-plane interferometry. He was awarded a Ruth L. Kirschstein NRSA individual postdoctoral fellowship from the NIH to advance his training in virology and fluorescence imaging systems.
Michael joined Janelia’s Light Microscopy facility as a research specialist, where he helps maintain a full complement of state-of-the-art instruments. Working closely with researchers, he provides microscope training as well as technical assistance for fluorescence imaging and image analysis techniques including organized workshops. He enjoys playing ultimate frisbee, traveling abroad, reading 19th century European literature, and dancing Argentine Tango.
