My research group utilizes metabolic & enzyme engineering to investigate and customize novel biosynthetic enzymes that can convert biomass-derived feedstocks into value-added chemicals. We have published highly acclaimed papers on model-guided enzyme engineering, process development, enzyme discovery using metagenomics and engineering metabolic control schemes that bridge with bioprocess control and improve productivity. Each of these works represents a critical advance in our ability to employ engineered microorganisms as a manufacturing platform. We also extend the principles of metabolic engineering to the design and development of unique bioremediation strategies to rehabilitate the water quality in and around industrial zones and new mining technologies and we are currently collaborating with Suncor and Jetti Resources, respectively, to deploy novel biotechnologies in the field. In addition to green engineering, my research group also pursues medical biotechnology research, and focuses on three stages in the drug discovery life cycle – (1) bioengineering for assay development, (2) biosynthetic engineering for lead generation, and (3) pharmaceutical product development. Our work on bioengineered assays aims to assemble three-dimensional, structured brain organoids from human pluripotent stem cells for use in pre-clinical screening of hits against Alzheimer’s disease. Through this work, we have established a formal collaboration with STEMCELL Technologies. Our work on pharmaceutical product development is advancing a concept that we dub ‘medicine-by-design’, a fast and low-cost methodology to advance a drug molecule from concept to formulated product based on the synergistic application of bioinformatics and data analysis, metabolic engineering and formulation science. We work closely with an industrial partner, InMed Pharmaceuticals, and have successfully advanced two projects to clinical testing. Our work on development of a ‘smart’ contact lens for treating glaucoma is among the most read scientific articles of 2018. Similarly, our work on the development of a printable bandage for healing damaged skin in patients suffering from Epidermolysis Bullosa Simplex (EBS) is currently under consideration for publication. Both works are the subjects of patent filings. We have recently initiated a new line of research in the group that fuses biology and materials science to develop better materials and transcend current limitations in manufacturing. The synergistic combination of biological systems with abiotic, functional materials that greatly improves the properties of the original host, and the resulting systems can be applied to a wealth of manufacturing, energy and environmental remediation applications. We laid the intellectual foundations of this paradigm in a forum article in Trends in Biotechnology and subsequently published a proof-of-concept study on a biohybrid photovoltaic cell that is the best in its class and could be used in bioorganic optoelectronics. My research group currently collaborates with 7 companies – STEMCELL Technologies, InMed Pharmaceuticals, Jetti Resources, Metabolik Technologies, Sanofi Pasteur, Reliance Industries Limited and Phytonix Corporation.

I support public scholarship, e.g. through the Public Scholars Initiative, and am available to supervise students and Postdocs interested in collaborating with external partners as part of their research.
I support experiential learning experiences, such as internships and work placements, for my graduate students and Postdocs.
I am open to hosting Visiting International Research Students (non-degree, up to 12 months).
I am interested in hiring Co-op students for research placements.

Complete these steps before you reach out to a faculty member!

Check requirements
  • Familiarize yourself with program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit the graduate degree program listing and program-specific websites.
  • Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study. This is either indicated in the program profile under "Admission Information & Requirements" - "Prepare Application" - "Supervision" or on the program website.
Focus your search
  • Identify specific faculty members who are conducting research in your specific area of interest.
  • Establish that your research interests align with the faculty member’s research interests.
    • Read up on the faculty members in the program and the research being conducted in the department.
    • Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
Make a good impression
  • Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
    • Do not send non-specific, mass emails to everyone in the department hoping for a match.
    • Address the faculty members by name. Your contact should be genuine rather than generic.
  • Include a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department. The supervision enquiry form guides you with targeted questions. Ensure to craft compelling answers to these questions.
  • Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to pique someone’s interest.
  • Demonstrate that you are familiar with their research:
    • Convey the specific ways you are a good fit for the program.
    • Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting.
  • Be enthusiastic, but don’t overdo it.
Attend an information session

G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

Biocatalysis and bioprocess engineering for terpenoid production (2019)

The biomanufacturing of terpenoids is limited by the low yields of heterologously expressed biosynthetic pathway and challenges associated with recovering these products at commercial scales. To enhance the flux through methylerythritol phosphate (MEP) pathway for terpenoid biosynthesis, I screened soil metagenomes for more active and stable orthologs of the rate-limiting enzymes. I successfully identified three entirely novel, natural fusions of IspD and IspF, one of which improved production of lycopene from 235 mg/L to 275 mg/L and production of isoprene from 3.6 mg/L to 6.3 mg/L when compared to the native enzyme overexpression. A comprehensive study of the role of the linking domain revealed the higher activity of each of the catalytic domains and the absence of substrate channeling. Moreover, the non-natural fusions of E. coli enzymes catalyzing consecutive steps were constructed. One such a fusion of IspD and IspE yielded 281 mg/L of lycopene, whereas the best performing fusion of IspE and IspF only yielded 39 mg/L of lycopene. Further investigation of the sequence of this biocatalytic cascade concluded the commencement with the activity of IspE, followed IspD and IspF suggesting the reactive plasticity in MEP pathway. I probed the promiscuous nature of terpene synthases (TSs) through the systematic study of monoterpene synthases from Picea abies in vivo and in vitro. I uncovered the influence of intracellular expression and oxygen supply on the promiscuity of TSs. Computational analysis revealed the putative roles of the amino acid residues within the active sites and their evolutionary trajectory. Finally, the fermentation of engineered E. coli strains for carene and myrcene were scaled up to 1 L and a newer technique was developed for efficient product capture using a fluidized bed capture device (FBCD) using a hydrophobic resin. The device was easy to integrate into the existing bioreactor set up. It yielded 2-fold higher carene titers and 17-fold higher myrcene titers.In conclusion, the three aspects of the terpenoid biomanufacture studied in this work address some of the biggest challenges facing the industry and lay strong foundations for commercialization of terpenoid biomanufacturing processes that employ genetically engineered microorganisms.

Novel approaches to treating and preventing malaria (2019)

Malaria presents a severe economic and healthcare burden for the developing world. Recent efforts to reduce the incidents of malaria-associated deaths achieved some success, but drug resistance is increasing and the number of drugs available to treat the diseases is thinning. The current thesis seeks to advance two complementary strategies to develop platform solutions to treat and prevent malaria. First, we applied cheminformatics to assess the chemical space of anti-malarial drugs to identify promising scaffolds. Open-source tools were used to analyze the scaffolds of candidates and approved anti-malarial drugs. Our scaffold-centric analysis reveals that the anti-malarial chemical space is disjointed and segregated into few dominant structural groups with these structures being distributed according to Paretos’ principle. This structural convergence can potentially be exploited for future drug discovery by incorporating it into bioinformatics workflows. This could be used to predict new combination therapies and areas for the development of new molecules.Our second strategy seeks to develop a better tool for repellent discovery; repellent usage to prevent mosquito bites is a safe way to control these infections. The current methods for repellent screening are time consuming. The olfactory pathway involves odorant receptors that form a heterodimeric ion channel with an odorant receptor co-receptor (Orco) and a switching odorant receptor (OR). The heterologous expression of these proteins in Xenopus-oocytes and HEK293 cells, have suggested that the Orco-OR complex is functional. While these hosts have permitted significant discoveries, they have slow growth rates and extensive handling requirements, which make them unwieldy for high-throughput screens. We sought to develop high-throughput repellent screens by reconstructing this olfactory pathway into a simpler host (Pichia pastoris) with the Orco receptor. The Anopheles gambiae Orco protein was successfully expressed, being able to discriminate between compounds (VUAA1, citronella and oct-1-en-3-ol) and doses (0.125 mM to 2 mM for VUAA1) when coupled with a reporter signal. In the future this system could be used to screen chemical libraries. Moreover, the heterologous expression of Orco protein could lead to future structural and functional investigation of OR compounds as well as the development of newer repellents and behavior-modifying compounds.

Functional metagenomics and consolidated bioprocessing for valorization of pulp and paper mill sludge (2018)

Biocatalyst discovery is integral to bioeconomy development, enabling design of scalable bioprocesses that can compete with the resource-intensive petrochemical industry. Uncultivated microbial communities within natural and engineered ecosystems provide a near-infinite reservoir of genomic diversity and metabolic potential that can be harnessed for this purpose. To bridge the cultivation gap, functional metagenomic screens have been developed to recover active genes directly from environmental samples. In this thesis, a pipeline for recovery of biomass-deconstructing biocatalysts sourced from pulp and paper mill sludge (PPS) metagenome is described. This environment is targeted given its high composition of cellulose that is hypothesized to direct enrichment of enzymes capable of hydrolysing it. The resulting oligosaccharides represent platform molecules that can be fed to downstream applications using consolidated process design for converting biological waste streams into value-added products. High-molecular weight DNA was extracted from sludge and used to construct a fosmid library containing 15,000 clones using the copy control system in EPI300™-T1 R E.coli. Extracted DNA was also used in whole genome shotgun sequencing to compare the metabolic potential of the sludge community with fosmid screening outcomes as well as other waste biomass environments using MetaPathways v2.5 software pipeline, with specific emphasis on carbohydrate-active enzymes (CAZymes). Metagenomic assembling, open reading frame (ORF) prediction, binning and taxonomic assignment approaches were also used to bring out correlations between function and taxonomy. In total, 32,232 ORF’s were mapped to the CAZy database predicted to encode glycoside hydrolases, glycosyl transferases, and carbohydrate binding module families. The fosmid library was screened for glycosidase hydrolase activities using a pool of sensitive fluorogenic glycosides of 6-chloro-4-methylumbelliferone (CMU). A total of 744 clones capable of converting pooled substrates were recovered indicating an extremely high hit rate (1 hit per 43 clones). Following fosmid sequencing and annotation, two of the most promising hits with defined single GH family loci were sub-cloned and overexpressed in E.coli BL21 DE3 strain to conduct basic biochemical characterization. Activity of purified enzymes was demonstrated on model lignocellulosic substrates to evaluate the potential of implementing the proposed circular bioprocess with waste PPS as both the feedstock and source of enriched biocatalysts.
