Ruby Sullan

Ruby Sullan is an Associate Professor in the Department of Environmental Science & Chemistry at the University of Toronto Scarborough (UTSC). Her research focuses on mechano-microbiology, nanomaterial-biosystem interactions, and bacterial biofilm formation. She leads the Mechano-microbiology Lab, investigating molecular forces governing bacterial adhesion and biofilm development, particularly at the single-cell and single-molecule levels.

Key research themes include:

• Molecular forces in bacterial biofilms
• Bacterial rigidity sensing
• Nanoparticle-antimicrobial platforms
• Nanoplastic-bacteria interactions in environmental systems
• Bacteria-root interactions
• Quantitative imaging of biofilm dynamics

Recent work emphasizes in situ analysis of biofilms using advanced techniques like single-cell force spectroscopy and nanoscale imaging. Her lab develops bioinspired nanomaterials targeting anti-biofilm therapies and environmental applications. Ongoing projects explore how mechanical forces influence microbial behavior and how nanomaterials can be engineered for precision medicine and environmental remediation.

Publications since 2021 reflect a focus on interdisciplinary approaches, including antimicrobial nanoparticle design, laser-responsive drug delivery systems, and mechanistic studies of nanoplastics in ecological contexts. The lab’s work has been supported by multiple funding streams, though specific grants are not detailed in the text. No scientific awards are explicitly mentioned.

Research outputs highlight advancements in:

• Antimicrobial nanocomposite hydrogels
• Single-cell mechanical interactions with plant roots
• Environmental toxicity of nanoplastics
• Biofilm matrix nanomechanics

Collaborations involve cross-disciplinary teams, though specific student/advisor relationships are not listed here.
