Dr. Mazda Kompanizare, Ph.D (E-mail)                                                                   

Mazda holds a Ph.D. in Hydrogeology from Shiraz University, Iran, under the supervision of Dr. Nowzar Samani. He is currently working on Hydrological connectivity of surface layers in some selected watersheds in northern Alberta. He is simulating the surface and groundwater flows and their interactions to determine how dry or wet scenarios of climate change can affect the hydrologic connectivity in those watersheds. He is working with GSFLOW for simulation of surface and groundwater flows and OSTRICH for multi-objective (MO) calibration of the model and post processing analysis.

He was lecturer at Bushehr University, Iran (1992-1995), assistant professor at Shiraz University ( 2004-2011), visiting scholar in Texas A and M University (2003) and visiting researcher in University of Waterloo (2011-2015). His previous work at the University of Waterloo Mazda was focused on the simulation of groundwater flow in variably saturated layers around an open pit mine in North of Ontario under supervision of Dr. Jonathan Price.  In this project he predicted the effect of mine dewatering on temporal and spatial changes in percolation rate through overburden layers and peat layers. He used HYDRUS3D for simulation of flow and UCODE for calibration of his model.


Dr. Olena Volik, M.Sc., M.Ed., Ph.D (E-mail)                                                                

Olena’s research focus is on carbon uptake and long-term storage along a salinity gradient within a saline, boreal, peat-forming wetland that represents an adequate model for wetlands reclamation in the Athabasca Oil Sands Region. Specific questions of interest include: reconstruction of temporal salinity change within the wetland using diatom-based transfer function and assessment of the main controls on salinity fluctuation over time; examination of the main controls on organic matter accumulation rate in open-water areas within the wetland over time; evaluation of degree of variability in long-term carbon accumulation rates within terrestrial areas of the wetland and assessment the main drivers of this variability; assessment of the main controls on recent carbon uptake along a salinity gradient. Olena’s study will endeavour to improve our understanding of carbon sequestration in natural saline fens that is useful for advancing fen construction in the region.


Dr. Matthew Elmes, B.A., M.Sc., Ph.D (E-mail)                                                                   

MattMatthew’s research interests are focussed primarily on the variability of peatland-landscape connectivity in the Western Boreal Plain (WBP), northern Alberta, and understanding the implications of climate change on peatlands connected to groundwater flow systems of varying scales (local, intermediate, and regional). Other interests include the effects of wildfire and oil sands mining activities on peatland watershed hydrology in the Athabasca Oil Sands Region of the WBP and associated hydrological feedbacks


Dr. Myroslava Khomik, Ph.D (E-mail)                                                                   

Myroslava is a biogeochemist with experience in terrestrial carbon cycling. In her work, she uses chamber and eddy covariance based methods to measure various components of ecosystem carbon fluxes and relates these to different environmental drivers using empirical modelling and statistics. She works closely with ecosystem modellers, providing them empirical data for model development and validation, and in turn uses their feedback to inform new experiments. She also works with colleagues who are experts in remote sensing, to find ways to improve our ability to estimate carbon emissions from remotely sensed data.

Myroslava’s research interests include improving our understanding of the impacts of land management practices and extreme weather events on soil and ecosystem greenhouse gas emissions. She is also interested in improving our understanding of various drivers of soil carbon emissions and in using that knowledge to improve process-based models of carbon turnover and remote-sensing-based models of carbon emissions. She has worked in boreal, temperate and oceanic climate zones.
