Milenka Andelic |
Milenka received her M.Sc. in Physics from Kyung Hee University, South Korea. She is currently a Ph.D. student working on the infrared plasmonics. She is using ultrahigh energy resolution electron energy loss spectroscopy (EELS), scanning transmission electron microscopy (STEM) and other related advanced techniques to characterize the plasmonic response of heavily doped semiconductor nanoantennas.
Peter Neathway  |
Peter received his Master's degree from the University of Waterloo in the Physics. His research is focused on investigating the impacts of defects in atomically thin materials. Substitutions and vacancies can modulate electronic and magnetic properties and be used to design materials for novel applications. Studying the corresponding impacts on local electronic band structure requires momentum, energy, and spatial resolution at the limits of existing technology. Electron microscopy can be used to both create these point defects and to fulfill the aforementioned resolution requirements, making it the ideal tool for this research.
Jingyi Qu  |
Jingyi received her Master's degree from Tianjin University, China in 2019 and joined the Botton Group as a PhD student soon after. She is currently working on the preparation and characterization of energy storage materials. For the preparation, the ALD technique is mainly focused on. With STEM, EELS, XRD2&3, FIB and other advanced techniques, she tries to explore the structural and chemical evolution of primary target-Li-ion battery materials.

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.
Isobel Bicket |
Isobel is a joint post-doc in the Botton group with M. While in the group she transferred from the Master's program to the PhD program after one year. Isobel's PhD research was on the studies of 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 post-doc in the Botton’s group. He finished his PhD on STEM Moire interferometry as a method to characterize 2D strain fields in crystalline materials in 2020. 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.
Research Asst
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.
