Alannah is an Associate Professor in the Department of Physics and Astronomy at the University of British Columbia. She heads the Quantum Materials Design Lab, which is part of the Blusson Quantum Matter Institute. Before starting her faculty position at UBC in 2019, she completed her PhD in Physics at McMaster University in 2017 and worked as a postdoctoral fellow at Rice University. Alannah’s research centers on the design and discovery of new magnetic quantum materials, whose quantum properties she studies using x-rays, neutrons, and muons. One of her overarching interests is disorder and its effect on material's properties. Having worked in both physics and chemistry departments, she is passionate about taking an interdisciplinary approach to the study of quantum materials. Alannah is a Sloan Research Fellow and the co-Director of CIFAR's Quantum Materials Program. When she's not growing crystals or at the beamline, Alannah loves cooking (and eating!), playing bridge, and learning to sail in the waters around beautiful British Columbia.
Mohamed is a research associate for the Disorder as a Design Principle Grand Challenge. Mohamed received the MEXT scholarship to pursue his PhD at Kyoto University working in the group of Yoshi Maeno. During his PhD, he discovered superconductivity in the hole-doped Antiperovskite Oxide Sr3-xSnO and studied the negative ionic state of Sn in this unusual oxide. Mohamed joined SBQMI in 2018 as a postdoc, primarily working with Doug Bonn, and he spent a part of his postdoc at Max Planck Institute in Stuttgart working with the groups of Hide Takagi and Bernhard Keimer. In the early part of his postdoc, he focused on high-pressure synthesis of new topological phases and silver containing compounds. Then his focus shifted towards identifying new topological materials related to the square-net family of compounds. As a research associate, he is working on synthesis of high entropy phases and measuring their properties. Besides research, Mohamed enjoys badminton, swimming, and eating chocolate.
Dongjoon joined SBQMI in 2022 as a research associate for growing crystals of quantum materials by state-of-the-art floating zone technique. He received his PhD in physics at Yonsei university, via photoemission spectroscopy experiments on high-transition-temperature superconductors. During his postdoctoral period as a JSPS fellow at the National Institute of Advanced Industrial Science and Technology in Japan, he carried out in-depth material growth to tailor-make the functionality of novel superconductors. Also, joining an innovative project, he explored new mixed-anion materials by using high-pressure synthesis technique. Then, he moved to Institute for Basic Science in South Korea and led a superconductivity team of center for correlated electron system. Dongjoon has marked milestones in research on cuprates, Fe-based superconductors and 4d transition-metal oxides. He also discovered Copper-Oxy-Telluride family that can be a potential platform of high-thermoelectric materials. Outside of the laboratory, he spends his time with drawing, running, traveling, and having coffee (a.k.a beer) with people.
Solveig is an SBQMI postdoctoral fellow for the Disorder as a Design Principle Grand Challenge. Solveig received her PhD in materials science at the Norwegian University of Science and Technology, working on ferroelectric materials under the guidance of professor Tor Grande. During her PhD work, she spent four months with professor Ulrich Aschauer at the University of Bern to learn more about density functional theory calculations. Solveig is interested in how disorder influences the functional properties of a material, and in the combination of computational and experimental work to study the crystal structure and thermodynamics of new phases. In her free time, she likes to be outdoors for hiking, running, or skiing, but she can also be found in the bouldering gym on a rainy day.
Ashutosh joined the Hallas lab at SBQMI in January 2024 as a postdoctoral research fellow, focusing on developing intermetallic and oxide quantum materials. He earned his PhD in materials science from JNCASR, Bangalore, under the guidance of Prof. Sebastian C. Peter. Throughout his doctoral studies, Ashutosh made significant contributions, uncovering a novel chiral intermetallic, investigating spin glass behavior in rare-earth-based intermetallic, and exploring the causes behind deficiencies in intermetallic compounds. Beyond his academic pursuits, Ashutosh indulges in badminton and table tennis as enjoyable pastimes. Ashutosh is the recipient of the prestigious UBC Killam Postdoctoral Fellowship.
Austin joined the Hallas lab in October 2024 as a postdoctoral research fellow. He received his PhD in chemistry from the Johns Hopkins University, working on the development of novel and adapted methods for the synthesis of novel quantum materials under the guidance of Prof. Tyrel M. McQueen. Austin is primarily interested in exploring synthesis under extreme conditions, particularly through the use of physical pressure, extreme oxidizers, and high-pressure hydrothermal and hydroflux conditions, towards the stabilization of novel highly-frustrated magnets and unconventional superconductivity. In addition to research, Austin enjoys hiking, exploring with his dog Hotpot, and playing Pokemon Go.
Samikshya joined the Hallas group as a graduate student in January 2020. Previously she received her BS-MS Dual degree in Physics as a DST-INSPIRE fellow from IISER, Bhopal, India. Her interests include working on designing and characterization of exotic phases of matter like frustrated magnetic systems. Besides physics and crystal growth, she enjoys sketching, playing tennis, occasional cooking, reading novels (mostly fictional), and traveling.
Mario joined the Hallas group in 2021 as a PhD student under a QUEST Scholarship from SBQMI. He received his B. Eng. in Nanotechnology from ITESO, and a MSc. in Materials Science from Universidad de Guadalajara, both in Mexico. For his Master’s, he worked in the relationship between the electronic and crystal structures of a rare-earth iron garnet from an experimental and computational point of view. Mario is interested in how controlled amounts of disorder in a crystal structure can lead to unexpected behavior, and enjoys crystal growth. When outside the lab, Mario enjoys playing basketball, photography, and training his dog.
Andree joined the Hallas group as a PhD student in January of 2025. She previously completed her BSc. Physics at UBC and MSc. Physics – Nanotechnology at the University of Waterloo, where she primarily investigated the low frequency 1/f noise in Josephson junctions for superconducting qubit applications. For her PhD, Andree is co-supervised by Prof. Ziliang Ye, who focuses on two-dimensional materials. As such, her project involves the growing of bulk rhombohedral TMDs which will then be exfoliated into 2D devices to investigate sliding ferroelectric switching. In her free time, Andree enjoys dancing, running, cycling, and frequenting coffee shops.
Before coming to Vancouver, Abraham earned his degree of B. Sc. Engineering Physics in the Tecnológico de Monterrey in Mexico. He then joined the Hallas Group in September 2023 as a master student. Abraham is interested in the properties in crystals grown by the floating zone technique that arise due to their quantum nature, in particular crystals with 214 Ruddlesden-Popper phases, which have previously shown very interesting phenomena. Outside of research, he enjoys dancing, hiking, cooking (for non-survival purposes), and photography.
William joined the Hallas group in June 2024 to get a head start to his chemistry M.Sc. jointly supervised by Prof. Sarah Burke. He completed his B.Sc. in chemistry with a minor in mathematics at SFU, conducting research supervised by Prof. Daniel Leznoff. There, he grew and investigated inorganic dithiolate crystals including non-centrosymmetric lead(II) and bismuth(III) complexes as well as emissive platinum(II) materials. William is excited to learn more about x-ray crystallography and crystal growth through his research in new quantum materials. Outside of the lab, William enjoys walking and roaming around, spending time with friends and staying up to date with One Piece.
Morgan is a fourth year undergraduate physics student, rejoining the Hallas group in 2024 for his Honours thesis project.

She is currently completing her Honours thesis in the Hallas lab where she is investigating the unconventional thermal expansion in high entropy oxides. Previously, she received an NSERC USRA to work in the Hallas group during the summer of 2024 studying the growth of high entropy oxides and rare earth oxysulfides. She hopes to learn more about the structures of these quantum materials, and how this influences their unique properties. Outside of physics, Ksenia is interested in running, hiking, yoga, and reading fiction.
