Dr. Avery McIntoshAvery McIntosh, Ph.D.

MIC Assistant Director and Research Scientist


Dr. McIntosh joined the Microscopy and Imaging Center in January 2018 to oversee daily operations of the Center. He received his Ph.D. in Physics from Texas A&M University in August 1998.  He has extensive experience in fluorescence spectroscopy and imaging including confocal and multiphoton laser scanning microscopy, fluorescence photobleaching recovery (FPR) fluctuation correlation spectroscopy (FCS), and fluorescence lifetime imaging (FLIM). 


Dr. Hansoo Kim
Research Scientist


Dr. Hansoo Kim joined the Microscopy and Imaging Center at TAMU in January 2008 as an Associate Research Scientist. He received his Ph.D. in Materials Science and Engineering from University of Florida at Gainesville in 2003. He preformed his postdoctoral researches at University of Pennsylvania before he became a research scientist at the University of North Texas. His research area has been synthesis and characterization of nanomaterials, morphological study on ionic polymers (ionomers), characterization of metallic composites. For these researches various kinds of conventional and advanced scanning and transmission electron microscopes have been major analytical tools. His research interests are analysis of materials for crystallographic, physical and chemical properties along with tomography of 3d-shaped materials using the analytical transmission electron microscopy TECNAI F20 and JEOL 2010.

Curriculum Vitae

Rick Littleton
Senior Research Associate


Rick Littleton is a Senior Research Associate with the Microscopy and Imaging Center. He joined the MIC staff in 1994 after working in the graphic design and photography industry then later as a consultant in wetland ecology and management. His duties include training, operation, and maintenance of the JEOL 1200 Transmission  Electron Microscope, training on the Nikon Stereo light microscope, and assisting in training and operation on the JEOL 6400 Scanning Electron Microscope. Rick's duties also include preparation and microtomy of TEM samples using the Ultracut E Microtome and overseeing the Center's entire photographic facilities.

Rick received a B.S. degree in Dairy Manufacturing from Texas A&M University in 1982 and a B.S. in Wildlife Ecology in 1992. Prior to working for the MIC he consulted on wetland delineation projects using physiological and morphological adaptation of plant species occurring in potential wetland areas. Rick also worked to identify the impact of bird populations as they relate to plant diversity in the management of seasonally flooded wetlands.

Dr. Michael Pendleton
Research Associate



Mike Pendleton received his Ph.D. in anthropology from Texas A&M University in 1993. He has been employed as an archeological surveyor in a national forest, as a consultant at archeological sites, and as a biological technician for the Southern Plains Agricultural Research Center, Agricultural Research Service, U.S.D.A. He studied, for instance, insect migration and foraging patterns by the analysis of pollen adhering to their bodies. Mike has mainly used SEM techniques for his archeological and biological research. In the Center, he was responsible for the Tescan Vega SEM before his retirement in September 2018.
