Research Scientist in Neuroscience
Biography
Many years of experience in worldwide laboratories (Russia, France, Norway and Hungary) lend to expertise in the methods of scanning and transmission electron microscopy including pre- and post-embedding immunolabeling. This also let me introduce to Yale the method of three-dimensional reconstruction of large cell fragments such as neuron cell bodies or processes from serial electron micrographs.
