Integrative Imaging

Small world. Big ideas.

We're Hiring!

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.

Jesse joined the Advanced Imaging Center in 2014, and has nearly 20 years’ experience in microscope design, development, and application across a wide range of biological models.  He previously was Senior Engineer at Vutara, Inc., where he helped to successfully commercialize 3D super-resolution microscopy systems.  Jesse performed postdoctoral work at Sandia National Laboratories, where he implemented several high-resolution optical imaging systems, including TIRF, STORM, hyperspectral, and STED microscopies, with biological applications ranging widely from cell surface receptor tracking and innate immune response, to algal biofuels research.  Jesse received his Ph.D. in Biomedical Engineering from the University of Texas at Austin.


Damien Alcor

Research Specialist

Damien joined the Light Microscopy Facility in 2017. Prior to joining Janelia, he managed the light microscopy facility of the Mediterranean Center for Molecular Medicine (Nice, France) for 5 years. This center is known for leading fundamental research in biology as well as translational research with clinicians. Damien was trained as a physical chemist, he received his Ph.D. from the department of Chemistry of the Ecole Normale Superieure (Paris, France). He then used his training in photophysics and photochemistry to develop his expertise in microscopy through research projects involving custom systems with a particular interest for techniques such as FRET, FLIM, SPT, FRAP, and FCS. Throughout his research projects and his support role in microscopy facilities, Damien has worked with a wide range of microscope modalities. He applied those in various fields of biology ranging from cell biology, cancer research, metabolic diseases, and neuroscience.

Heather Cartwright

Application Scientist

Prior to joining AIC, Heather worked in light microscopy cores at the National Institute of Allergy and Infectious Diseases, Stowers Institute for Medical Research, and Carnegie Institution’s Department of Plant Biology, where she was director for eight years. While at Carnegie, she built a modified OpenSPIM light sheet and a custom macro system for imaging the phototropic response. After departing Carnegie, she was an applications scientist at Intelligent Imaging Innovations, where she supported the Marianas LightSheet (diSPIM).


Heather received her Ph.D. in cell and developmental biology from the University of California, San Diego.


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.

Leanna Eisenman

Cell Culture Technician

Leanna joined the AIC in November 2021 as a Research Technician.  She provides support in cell culture and sample preparation for the AIC.  Prior to joining the AIC, she worked at the University of Pittsburgh’s Neurobiology Department.

Chad Hobson.jpg

Chad Hobson

Application Scientist

Chad joined the AIC as a recent PhD graduate from the department of physics and astronomy the University of North Carolina at Chapel Hill. His PhD research in Rich Superfine's lab focused on combining atomic force microscopy and single-objective light-sheet microscopy to study the mechanical properties of cell nuclei. At the AIC, Chad works primarily on the various light-sheet microscopy systems, assisting visitors from consultation to publication. Prior to graduate school, Chad received his BS in both physics and mathematics at the University of Lynchburg, where he developed models of the Tour de France and soccer ball aerodynamics.
