Amin Hashemi |
Amin (Mohammad Taghi Hashemi) received his B.S. from Sharif University of Technology, Iran in 2017. His thesis was on the synthesis and characterization of core-shell PbS-Graphene quantum dots used for NIR Bio-imaging. He now uses SEM, TEM and its related characterization techniques such as EELS and EDS to investigate the Li-ion battery materials and understand the dynamics of structural/chemical in these materials after cycling.
Tyler Champagne-Peacock  |
Tyler received his B.Sc. in Chemistry from Wilfrid Laurier University in 2017. He will use SEM-EBL to build plasmonic nanostructures as well as STEM-EELS to characterize the plasmonic behaviour in the IR region for the potential use of ITO as an alternative material to gold and silver for plasmonic devices. 
Isobel Bicket |
Isobel received her BASc from the University of Waterloo in 2014, joining the Botton group shortly after. She transferred from the Master's program to the PhD program after one year. Isobel's currently studies plasmon resonance modes in 3D nanostructures (and others!) using electron energy loss spectroscopy (EELS) and other advanced techniques to try to characterize the in-plane electromagnetic fields of the resonance modes.
Alex Pofelski |
Alex is currently a PhD student in the Botton’s group working on STEM Moire interferometry as a method to characterize 2D strain fields in crystalline materials. He has over 6 years experience as a TEM analyst in the semiconductor industry in the past. Alex has also a Masters degree in Physics and Nanoscience program that he earned in 2009 from Grenoble-INP PHELMA Institute, France.
Nafiseh Zaker |
Nafiseh received her M.Sc. in Materials Science and Engineering from Sharif University of Technology, Iran. She is currently a Ph.D. student working on the characterization of Li-ion batteries, implementing different approaches. Li-ion batteries chemical composition, morphology, internal microstructural stresses, and their electrochemical performance and efficiency are some of the aspects that she is currently scrutinizing for her thesis. To this end, she is utilizing TEM, SEM, EDX, EELS and other high-end techniques to better understand and characterize the Li-ion batteries.  
Shayan Mausavi |
Shayan received his B.Sc. from Sharif University of Technology, Iran. His thesis was on the synthesis of nanostructured materials for electrochemical biosensing applications. He works on the  plasmonic biosensors fabrication, for final application of DNA detection. For his studies, he majorly uses photoelectrochemical methods, electron energy loss spectroscopy (EELS), photolithography, electron beam lithography, and related simulation methods.
 Hanshuo Liu |
Hanshuo received her Masters from the University of Science and Technology Beijing in 2012, and finished her PhD from McMaster University in 2017. Her current research focuses on the characterization of structural and chemical evolution of energy storage materials, primarily the lithium-ion battery materials. For this she uses advanced electron microscopy techniques such as, HAADF-STEM imaging, EELS and FIB-tomography. 
Maureen J. Lagos |
Maureen is currently a Research Associate in Botton's group. His current research focuses on the understanding of the vibrational scattering in nanostructures using electron probes. For his PhD thesis he worked on the structural effects on the quantum conductance of metal nanowires using in-situ HRTEM. In addition, he has also worked on the temporal aspects of the inelastic electron scattering associated with plasmon excitations.
