Elena B. Kiseleva, has a PhD in biology (Biophysics), she is a researcher of Laboratory of Optical coherence tomography (OCT) of the Privolzhskiy Research Medical University (Nizhny Novgorod, Russia). Her research ranges from optical imaging of biotissues, in particular, cross-polarization (CP) and angiographic OCT, polarization and nonlinear microscopy to histological evaluation of tumor and normal tissues response to different types of treatment (PDT, radiation therapy). She has contributed to the development of the numerical processing of CP OCT images (quantification of OCT signal and improvement the OCT contrast) for differential diagnostics of mucosal and brain diseases; to studies of myelinated fibers changes due to glioma invasion and radiation-induced changes of bladder and rectum collagen structure. Her research experience includes over 12 years in application of OCT devices in experimental and clinical studies. She is an author more than 70 publication on OCT.
