Bio

Daniel, as expected from a theoretical physicist, likes wearing ‘Green Lantern’ symbology, discussing depths of ’The Matrix’ and playing board games. Additionally, Daniel is a movie maniac and collector of vinyl records. He plays drums and guitar, and equally loves vegan food, sushi and jamón serrano (no incongruence at all).
Daniel leads the theoretical and computational side of the Z-lab. He’s actively involved in projects from different subfields in the lab, from differentiation patterns in organoid structures to differentiation trajectories in hematopoietic stem cells, where he is emphasizing in the control aspects of these lines. In this direction, Daniel is opening new research lines in the control of growth in functional organoids, and in the detection, quantification, analysis and control of emergent properties, with the latter research line being translationally applied through the different areas composing the Stem Cell Bioengineering lab.

Frank Hsu

Lab Technician

Education

Free University of Brussels, Brussels, Belgium
Masters, Molecular Genetics

Bio

I completed my MSc training in Molecular Genetics at the University of Brussels, Belgium. I have been fortunate to work with an enthusiastic group of graduate students and researchers in this lab for over a decade. My responsibilities include overseeing the daily activities of the lab, organizing and controlling all aspects of the lab environment, ordering and keeping track of all equipment and supplies, and maintaining and stocking all hESC lines.

Beth Castle

Beth Castle

Education

Dalhousie University, Halifax, NS, Canada
Master of Science, Microbiology and Immunology
Dalhousie University, Halifax, NS, Canada
Bachelor of Science, Microbiology and Immunology

Bio

Once upon a time, Beth lived in a distant eastern land, Halifornia. There her first love was viruses, an evasive love, but infectious nonetheless. Alas, as life goes, she continued her journey west and a new love stemmed. While this new romance felt cell-fish, Beth dove right in to exploring the early stages of development of blood and immune cells.
Now, she is trying to understand how the spatial context of developing cells can tune what type of cell they become. It’s bloody exciting.
In her new life in BC, Beth likes to run, cook, go up and then back down mountains (through a variety of methods) and make lots of bad puns.
Catherine Ko

Catherine Ko

Education

University of Calgary, Calgary, AB, Canada
Bachelor of Science, Biomedical Engineering

Bio

Catherine is working on developing a smart bioprocess control system for real-time monitoring of hiPSC differentiation into hematopoietic stem and progenitor cells. Drawing on her background in scale-up and bioreactor engineering, her work integrates real-time process monitoring with computational modelling to better understand and control the differentiation process, ultimately aiming to improve reproducibility and scalability in cell manufacturing.
Catherine grew up in Alberta and has happily traded the mountains for Vancouver’s beaches (rain or shine but mostly rain). She travels every chance she gets, as she believe the best way to understand a city is to walk until your feet hurt, following her stomach to the best local food, and photographing everything along the way (her camera roll has zero interest in reproducibility).

University of Toronto, Toronto, ON, Canada
Bachelors of Science, Immunology

Bio

Cellular engineering is a crucial area in developing personalized medicine. Synthetic biology takes advantage of advancements in DNA synthesis, molecular and computational biology to design and engineer customized synthetic signaling pathways that allows for “smart” forward programming of the cell based on their transcriptomic state.
Charles focuses on using synthetic biology to influence cell development and cell fate of pluripotent stem cells with the goal of generating specific cell types for regenerative immunotherapy.
Always down for a drink. If you want to get me drunk, one drink is all it takes. Interesting include archery, guitar, video games and distracting people from their work.
Darian Ellis

Darian Ellis

Ph.D.
 

Education

University of Toronto, Toronto, ON, Canada
Bachelor of Science, Biological Physics and Neuroscience

Bio

Cell fate is shaped by changing interactions between cellular signaling, gene regulation, and chromatin state. Darian’s research will focus on developing synthetic biology tools that can sense cellular states and guide pluripotent stem cells toward desired fates. To make this possible, he will engineer gene circuits that can interpret changing developmental signals while remaining functional as cells differentiate. These tools could enable more reliable production of specialized cells for regenerative medicine and engineered cell therapies.
This is Darian’s first time living on the West Coast, and he is really enjoying the climate. He is impatiently awaiting the next book in The Stormlight Archive, but until then will pass the time rewatching Star Wars, playing video games, and enjoying nature.

Divy Raval

Education

University of Toronto, Toronto, ON, Canada
Bachelor of Applied Science, Engineering Science (Biomedical Engineering Major, Robotics Minor)

Bio

Differentiating cells face numerous lineage-fate decisions throughout their development. Divy is utilizing computational approaches to investigate the regulatory state that controls the bifurcation of iPSC-derived T cells towards the naive cytotoxic and helper T cell fates. Variations between the regulatory states of iPSC-derived T cells and naturally developing T cells may elucidate perturbable variables for robustly controlling cell fate in vitro.
Outside the grind, Divy enjoys playing chess (he sucks), eating food (a lot), and watching movies (he excels).

Lauren Durland

Lauren Durland

Education

University of Toronto, Toronto, ON, Canada
Bachelor of science, Molecular Genetics and Physiology

Bio

CAR-T cell therapy has revolutionized cancer treatment. While this approach has achieved remarkable success in blood cancers, the efficacy is relatively limited in solid tumors. Lauren is developing a T-cell compatible tumor-on-a-chip model to understand the reasons for CAR-T cell dysfunction in the solid tumor microenvironment. These insights will be used to inform design strategies for CAR-T cells with improved function in solid tumors.
When she’s not in the lab, Lauren loves to run, ski, and explore new places around Vancouver.

Bio

If you had the chance to change your fate, wouldja?” — Brave (2012)
As individuals age, hematopoietic stem cells increasingly favor myeloid over lymphoid differentiation, depleting T cells and weakening the immune system. This leads to poorer vaccine responses, higher autoimmunity risk, and reduced immune defenses. Taia is interested in whether this shift can be reversed by testing blood stem cell culture conditions, small molecules, and cytokine combinations to restore T cell output. Her long-term goal is to develop autologous cell therapies to reconstitute immune function in aging or immunodeficient patients.
Outside of the lab, Taia loves to educate others about biomedical engineering through workshops, activities, and lectures. Additionally, she loves to run around, try new restaurants, and take on random side projects. 🙂
Thristan Taberna

Thristan Taberna

Education

University of Calgary, Calgary, AB, Canada
Bachelor of Science, Chemical Engineering (Biomedical Engineering Specialization)

Bio

T cell therapies have shown tremendous clinical efficacy against deadly diseases such as cancer. However, expensive production processes hamper the widespread application of this approach. Pluripotent stem cells can self-renew and become T cells. Thristan aims to harness the unlimited potential of pluripotent stem cells to produce off-the-shelf cellular therapeutics. Using cell and process engineering tools, Thristan hopes to develop a robust, scalable, and cost-effective bioprocess that guides pluripotent stem cells to become T cells.
Outside the lab, Thristan enjoys trying out food from around the world, kickboxing, binge-watching shows on Netflix, listening to audiobooks, and hiking.
