Post-Doctoral Fellowships
Toshitaka Hayashi, Ph.D.
Dr. Toshitaka Hayashi is currently a postdoctoral researcher at the Faculty of Science, University of Hradec Kralove, studying machine learning algorithms for BCG signals. He has obtained a Ph.D. degree in Software and Information Science from Iwate Prefectural University, Japan.
His research topic is machine learning algorithms with limited training data. Especially, he has an interest in how to detect unseen data. Research keyword is One-class classification, Anomaly detection, Self-supervised learning, Data imbalanced classification. His primary publication is Less-complexity one-class classification approach using construction error of image transformation network from Information Science Journal.
RNDr. Oleksandr Kozlov, PhD.
Oleksandr Kozlov completed his doctoral studies in the Analytical Chemistry program at the Faculty of Science of the Pavel Jozef Šafárik University in Košice in 2020. During his studies in 2018, he completed an 8-month internship at the Department of Physical and Macromolecular Chemistry at Charles University in Prague.
He has long been engaged in the analysis of biologically active substances using chromatographic methods. He published the results of his work in international peer-reviewed journals. He is currently a postdoctoral fellow at the Department of Chemistry, University of Hradec Králové, where he deals with metabolomic and lipidomic analysis of biological samples using supercritical fluid chromatography combined with mass spectrometry. His other scientific interests include chiral separations.
RNDr. Miroslav Psotka, PhD.
RNDr. Miroslav Psotka, PhD. studied at Department of Organic Chemistry, Faculty of Science, P. J. Šafárik University in Košice, Slovakia. He studied here organic chemistry for five years and then work as a scientist in the organic synthetic laboratory on his doctoral studies under supervision of Professor Jozef Gonda.
He stayed for five months on Erasmus education stay at Rijksuniversiteit Groningen, Netherlands where he worked out Small research project Wittig reactions of stabilized ylides in water conditions.
From beginning of september 2016 he applied for Post-Doc fellow - Junior researcher position at Biomedical Research Centre at Faculty hospital in Hradec Králové. In november 2017 he successfully defended his PhD thesis Shikimic acid as a precursor for the preparation of 3-deoxy-D-arabino-2-heptulosonates and chiral aminopolyols at P. J. Šafárik University in Košice, Slovakia. He was also working at Department of Toxicology and Military Pharmacy, Faculty of Military Health Sciences in Hradec Králové.
From 2018 till these days he is working at University of Hradec Kralove, Faculty of Science, Department of Chemistry. His scope of employment is synthesis of biological active natural compounds used as insecticides, anticancer drugs and for Alzheimer disease and incontinence treatment. He also do structure analysis (NMR; MS; HRMS), preparing samples for solubility and biological activity measurements.
RNDr. Lenka Plavcová, Ph.D.
RNDr. Lenka Plavcová, Ph.D. received her Bachelor's and Master's degrees from the University of South Bohemia in České Budějovice. She completed her PhD studies (2008-2012) at the University of Alberta, Canada, in the field of forest ecology and management, where she studied the mechanism causing cavitation in xylem plants. She worked as a postdoc at the Technical University of Vienna and as a Humboldt Foundation Fellow in Ulm, Germany. Since 2015, she has been working at the University of Hradec Kralove, however, her scientific activity was interrupted three times by parental leave.
At the Department of Biology she is now working on the ecophysiology of woody plants with a focus on xylem structure and function. In her research she uses methods of functional anatomy, water potential measurements, leaf gas exchange measurements and dendrometry. The main objective of the research is to improve knowledge of the factors that control radial and axial parenchyma diversity in tropical tree species and to determine how parenchyma anatomy relates to the growth characteristics of these tree species.
