Job Title

Professor at the Institute of Chemical Engineering, Bulgarian Academy of Sciences, Sofia, Bulgaria

Research interests

I am interested in the molecular-scale mechanisms of aqueous ion interaction with mineral and bacterial surfaces, including complexation, sorption, incorporation, surface-controlled precipitation, and redox reactions. I am also studying metal transformations caused by the respiration of bacteria, including direct enzymatic redox processes and indirect processes occurring through reduced iron or sulfur minerals. These fundamental processes are studied in the biogeochemical context of metal, metalloid, and radionuclide transport in natural and engineered environments. I employ synchrotron x-ray spectroscopy (XANES and EXAFS) to determine the molecular structure around the metals, as well X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), acid/base titration, and atomic emission spectroscopy (ICP-AES) to determine uptake and precipitation. I am also developing and applying x-ray fluorescence and soil tomography imaging techniques at micron and sub-micron spatial resolution.


The projects I am involved with can be described as Condensed Matter Physics and Physical-Chemistry problems related to Molecular Environmental Science. 


More details on these projects, my professional qualification, publications, and awards can be found in my Résumé (web format).  A typeset version for letter paper can be downloaded in pdf format.


The publications in the Résumé are available upon request.


I am currently a member of the Transfer Processes in Multiphase Media Laboratory at the Institute of Chemical Engineering, Bulgarian Academy of Sciences.


Previously I was a staff scientist at the Biosciences Division of Argonne National Laboratory as part of the Subsurface Biogeochemical Research Science Focus Area project.


Before that I was a faculty member (assistant professor) at the Department of Solid State Physics in the Faculty of Physics at the University of Sofia, Bulgaria.


My post-doctoral experience was with the Molecular Environmental Science group led by Dr. Ken Kemner, at the Biosciences Division of Argonne National Laboratory.


Most of our synchrotron experiments are performed at the MRCAT beamline, sector 10-ID at the Advanced Photon Source.


I also actively collaborate with the group of Prof. Bruce Bunker at the Department of Physics and the group of Prof. Jeremy Fein from the Department of Civil and Environmental Engineering and Earth Sciences, both at the University of Notre Dame which is where I got my Ph.D. degree from.
