Soniya Naik, PhD
Postdoctoral Fellow

Soniya Naik, a postdoctoral fellow at Bressler’s lab, holds a Ph.D. in chemistry and is currently pioneering research in the bio-jet fuel project. As air transportation demands soar, the development of sustainable aviation fuels becomes increasingly critical. Her work builds on earlier findings that highlighted a substantial boost in branched hydrocarbon yields during lipid pyrolysis, an essential component that enhances jet fuel's freezing point. Her research is in on catalytic isomerization of these renewable hydrocarbons, focusing on synthesizing and characterizing catalysts to improve branching and cold flow properties, thereby meeting aviation industry standards. Pursuing a hydrogen-free methodology, she aims to deepen the understanding of this chemical process and enhance the cost-effectiveness of sustainable aviation fuel production. Her approach holds the potential for significant advancements in energy sustainability, contributing to global efforts to combat climate change.

Mark Lawley, PhD
Postdoctoral Fellow

Mark did his PhD thesis in chemical engineering on novel solvent extractions for the biopolymer poly(hydroxybutyrate). As a postdoctoral fellow in the Bressler Lab, Mark’s research looks at the optimization and scaling of bioreactor and downstream process operations for single-cell protein production processes. Single-cell protein has the potential to greatly reduce the carbon intensity and land-use impacts of animal feed while providing a way to valorize byproducts of other processes.

Beyond the laboratory, Andrés is actively involved with the Catholic Students' Association and several social justice initiatives, where his contributions resonate with his advocacy for science, education, and faith. His multifaceted involvement illustrates a commitment to not only scientific inquiry but also to the cultivation of an integrated, socially responsible scientific community.

Bernardo Araujo Souto
PhD Candidate 

Bernardo obtained his bachelor’s degree in Chemical Engineering at the Federal University of Itajuba, Brazil. He worked as an undergraduate researcher in organic synthesis, focused on the microwave approach to obtain possible bioactive compounds. After that, Bernardo worked as an intern at the Brazilian Center for Research in Energy and Materials, when he studied the synthesis of bioactive compounds for heart disease. At the end of his undergraduate, he participated in the Mitacs internship when he joined Dr. Bressler’s lab to work on preliminary studies on microwave heating for the Lipid-to Hydrocarbon (LTH) project.

Nowadays, he is pursuing his Ph.D. degree at Dr. Bressler’s lab, working on the bio-jet fuel project. With the increasing demand for air transportation, the investigation of biofuel production for aviation is necessary to develop a sustainable fuel. Previous work at the lab showed the application of short alkene gases enhanced the branched hydrocarbons yield. This essential fuel fraction improves its freezing point, which is a desirable property for jet fuel. In this way, Bernardo’s research is focused on optimizing processes with four-carbon compounds to improve branching and cold flow properties to meet aviation industry standards, using model lipid compounds and the real feedstock. In addition, the study will focus on understating how the structural variability may affect the properties of the bio-jet fuel.

Bingxin Hai
PhD Candidate

In alignment with the global movement towards energy transition collaboration, Bingxin is dedicated to contributing to this transformative effort. Currently pursuing a Ph.D. in Bioresource Technology, her research builds upon prior findings that demonstrated a significant increase in the yield of branched hydrocarbons during lipid pyrolysis when short-chain alkenes are introduced. These hydrocarbons are crucial for enhancing the properties of aviation fuels, such as a reduced freezing point. Bingxin's current focus lies in investigating the reaction chemistries inherent in fatty acids and propylene pyrolysis, with the overarching goal of advancing the viability and competitiveness of sustainable aviation fuels.

Before joining the group, she earned a Bachelor’s degree in Food Science with Honors from the University of Alberta. Along her academic journey, she gained valuable experience through multiple internships in diverse industries, including both the food sector and the energy industry. This background equips her with a holistic perspective as she dedicates herself to the pursuit of innovative solutions within sustainable energy.

Endriss Ali Umer

Haley Wolgien-Lowe
MSc Student 

Haley obtained her bachelor’s degree in chemistry and biochemistry from Concordia University of Edmonton and also holds a technical diploma in Chemical Technology from the Northern Alberta Institute of Technology in Edmonton. Her undergraduate research involved developing analytical methods for the determination of advanced glycation end products in both laboratory and food matrices. Outside of academia, Haley has extensive work experience undertaking product development of cosmetic, nutraceutical, and food formulations. She also has experience in process development, scale-up, and pilot plant operations of natural health products obtained from working at the University of Alberta’s Agri-Food Discovery Place. Haley is now engaged in a master’s degree in bioresource technology under the supervision of Dr. Bressler at the University of Alberta. Her research addresses the issues around conventional animal feed sources and their implications for global food availability.

The soy and fishing industries are largely devoted to producing protein for animal feed, which contributes to deforestation, strip mining of our oceans, and food insecurity. Given these concerns as well as the growing world population, it is desirable to find alternative sources of animal feed protein so soy and fish can be redirected for human consumption. The Bressler Lab is developing an alternative protein source called single cell protein, which is produced through fermentation of bacteria. Haley’s research focuses on developing a scalable downstream processing system to separate the fermentation product to obtain single cell protein in a form suitable for animal feed.

Domenic Marano
MSc Student 

Domenic obtained his bachelor's degree in biochemistry from the University of Alberta. His undergraduate research largely involved synthetic biology in the realm of probiotic development and the determination of lipid biosynthetic pathways in Saccharomyces cerevisiae. During his undergraduate degree, Domenic worked as an intern at Teck Resources, where he studied the biorecovery of rare earth metals from mine tailings. At the end of his undergraduate studies, he completed a Mitacs internship in Dr. Bressler’s lab, where he assisted in the operation and development of a novel high-performance single-cell protein continuous fermentation system. Domenic is currently pursuing a master’s degree in bioresource technology under Dr. Bressler at the University of Alberta. His research focuses on valorizing spent fermentation media for recycling, aiming to enhance sustainability and resource efficiency in industrial bioprocessing.

Preston Tran
MSc Student 

Preston obtained his bachelor’s degree in Biochemistry with Honors from the University of Alberta. His undergraduate research led him to develop an interest for synthetic biology and its applications in industry. During his studies, Preston worked to modify a diverse array of bacteria, yeast and fungi for purposes ranging from nanobody secretion to biofuel production. More recently, he worked to engineer Aspergillus oryzae to express bovine myoglobin, laying the foundation for a beef alternative. Preston was also part of a team that represented the University of Alberta at the International Genetically Engineered Machine (iGEM) competition, earning a silver medal in 2023. He focused on developing a biological sensor for Fusarium head blight (FHB) in cereal crops utilizing fluorescence and an autonomous drone system. In the Bressler lab, Preston’s work will involve optimizing methanol fermentation for the production of single cell protein (SCP), building on the former ICI Pruteen process.
