Post Doctoral Fellows, Research, and Management Staff


Ivy Yang, PhDIvy
Ivy is working in the Groundwater Lab under the co-supervision of Professors Brent Sleep and Elizabeth Edwards. Ivy is involved in two projects, carrying out a field study with MASc Michael Previdsa, where coarse ZVI was injected into the ground at a site with 1,1,1-trichloroethylene (1,1,1-TCA) and dichloromethane (DCM) contamination. Besides GC analyses of all groundwater samples, Ivy will performe high-throughput amplicon sequencing and quantitative polymerase chain reaction (q-PCR) to assess the changes in the microbial community in the groundwater during the in-situ remediation. In her second project, Ivy is looking at the influence of the addition of different dosages of nanoscale zero valent iron (nZVI) on the microbial communities degrading tetrachloroethylene (PCE) in batch assays.

Research Staff

Line Lohmheim, M.A.Sc.
Research Technician – BioZone UofT. In addition to helping keep the BioZone labs working smoothly, Line performs remediation treatability tests using bioremediation technologies such as biostimulation and bioaugmentation. She is involved in the analyses and experiments using nZVI as a remediation technology.

Pulin Mondal, PhD
Dr. Mondal is a Research Associate in Professor Brent Sleep’s research group at the University of Toronto. Pulin is investigating in-situ chemical oxidation (ISCO) of BTEX compounds by thermally- and chemically- activated persulfate, and the effects of persulfate oxidation on biodegradation of BTEX and the oxidation biproducts. He is also working on CMC-stabilized nZVI transport in porous media. Pulin completed his Ph.D. in July 2012, in Civil Engineering (specialized in Environmental Engineering) at the University of Toronto, under the supervision of Professor Sleep. His Ph.D. research focused on identifying important environmental factors affecting virus and virus-sized particle transport in variable aperture rock fractures through laboratory-scale experiments and modelling. Pulin completed his master’s degree in Environmental Engineering at the University of Windsor. During the master’s program, he worked on improving operational performance of slow sand filters by using non-woven fabric. He received a Bachelor degree in Civil Engineering from the Bangladesh University of Engineering and Technology (BUET). Email:

Jorge Luis Gabayet Dominguez, Western – Reaserch Engineer with Professor Gerhard – STAR Team

Project Manager

Glaucia Lima, PhD
Dr. Lima graduated in Civil Engineering from the Federal University of Espirito Santo (Brazil) and obtained her M.Sc. degree from the Federal University of Rio de Janeiro (Brazil). In 2005, under supervision of Prof Brent Sleep, she obtained her Ph.D. from the University of Toronto. Her PhD thesis involved laboratory column studies in compacted soils and carbon tetrachloride contamination. Until February 2008, Dr. Lima held a faculty position at the Federal University of Espirito Santo until she moved to Canada, in February 2008, where she joined Prof. Beth Parker’s research group at the University of Guelph. In October 2011, Dr. Lima re-joined Prof. Brent Sleep’s group as Project Manager of his ORF-RE Water Round Project. Email:
