Bio: Dr. Derakhshani leads the TLMR Lab with a focus on decoding the complex interactions between livestock hosts and their resident microbiota. With a background in veterinary medicine and microbial ecology, he drives the lab's strategic direction.

Research Focus:

  • Host-microbe interactions in ruminants and swine.
  • Development of microbiome-based therapeutics.
  • Integration of multi-omics data (metagenomics, metatranscriptomics, metabolomics).

Postdoctoral Fellows

Dr. Rahman

Dr. A S M Zisanur Rahman

Bio: Dr. Rahman is a Postdoctoral Fellow specializing in molecular microbiology, chemical genetics, and advanced computational biology. He leads the lab's computational pipelines development for analyzing complex metagenomic and genome-resolved datasets.

Research Focus: Dr. Rahman's research focuses on multiomics integration with metabolic modeling, and artificial intelligence-driven approaches to reduce enteric methane emissions from ruminant livestock.


Graduate Students

PhD Students

Nahidur Rahman

Nahidur Rahman

Bio: Nahidur is a PhD student, co-supervised by Dr. Nazim Cicek and Dr. Hooman Derakhshani. He holds a Doctor of Veterinary Medicine (DVM) degree (2021) and a Master’s degree in Microbiology (2023) from Sylhet Agricultural University, Bangladesh.

Research Focus: Nahidur's research is situated within a One Health framework and focuses on understanding and tracking the spread of antimicrobial resistance (AMR) in the dairy industry through microbiome and genomic data. His work aims to develop comprehensive databases and analytical approaches to support AMR surveillance and risk assessment across animal production systems.

MSc Students

Larissa Scott

Larissa Scott

Bio: Larissa is an MSc student researching the cattle microbiome and its role in enteric methane emissions. She holds a bachelor's degree in Animal Science and has previous experience working in a veterinary clinic, as well as in food safety and inspection. Outside of research, she spends much of her time with her horse and dog, and unapologetically enjoys winter and snow.

Research Focus: Larissa’s research focuses on characterizing the rumen microbiota and fermentation pathways. Her aim is to identify homoacetogenic bacteria and anti-methanogenic natural products to mitigate enteric methane emissions.

Fatemeh Mohammadian

Fatemeh Mohammadian

Bio: Fatemeh is an MSc student studying swine gut microbiome. She earned her Doctorate of Veterinary Medicine (DVM) from Ferdowsi University, Iran. She also founded and managed a veterinary clinic and pharmacy in Iran before joining the lab.

Research Focus: Fatemeh's research focuses on the culturing and genomic characterization of swine gut bacteria to uncover antimicrobial biosynthetic potential and identify novel strains with promise as next-generation probiotics and therapeutic agents.

Anindita Roy

Anindita Roy

Bio: Anindita is an MSc student with background in biotechnology and genetic engineering. She has prior research experience in microbial culture (bacteria, bacteriophages, and cyanobacteria), animal disease models, animal cell culture, and gut inflammation, with a particular focus on probiotic and synbiotic regulation of intestinal inflammation and host immune signaling.

Research Focus: Anindita's research evaluates postbiotics as dietary interventions to improve gut health, immune development, and passive immunity transfer from sows to piglets, with the goal of mitigating post-weaning diarrhea (PWD). Her interests include host–microbiome interactions, mucosal immunity, gut barrier function, immune modulation, and translational strategies to improve health and resilience in intensive swine production systems.

Gary Chan

Gary Chan

Bio: Gary previously worked as a Research Assistant at the School of Public Health, University of Hong Kong, where he contributed to projects focused on antimicrobial resistance, the human microbiome, and One Health. He is currently an MSc student in Dr. Derakhshani’s research group and is affiliated with Agriculture and Agri-Food Canada.

Research Focus: Gary’s research focuses on the transmission of antimicrobial resistance in Canadian agricultural systems and the development of mitigation strategies.

Arezoo Alizadeh

Arezoo Alizadeh

Research Technician

Bio: Arezoo manages daily lab operations, ensuring safety compliance and overseeing ongoing projects in the lab. She holds a Doctor of Veterinary Medicine degree and an MSc degree in Animal Science.

Expertise: Sample processing, project management, molecular biology workflows.

Tasneem Hassan Muna

Tasneem Hassan Muna

Research Technician

Bio: Tasneem supports the lab’s experimental and analytical workflows, with a strong background in protein and structural biology, proteomics, and mammalian cell culture. She contributes to molecular and proteomic analyses that complement the lab’s microbiome and genomics research. She is currently involved in high-throughput screening of microbial natural products against common pathogens and in assessing host immune responses following exposure to these natural products.

Expertise: Protein biology, X-ray crystallography, proteomics, mammalian cell culture, host–microbe interaction assays, and anaerobic culturing.
