Herb Schellhorn - Department of Biology

McMaster University will continue to host undergraduate academic activities remotely for the Spring/Summer/Intersession term with only a few exceptions for courses that need student access to specialized equipment.

More Information

Research in the area of ‘bioinformatics and functional genomics’ leverages the power of genomic and post-genomic technologies, to address fundamentally important biological questions in a wide range of organisms, from a molecular level, through to a population perspective. Our laboratories provide a superb training environment for motivated post-doctoral fellows, graduate students and undergraduates.

Research Highlights

3.5 million dollar Ontario Research Fund grant awarded to Dr. Weretilnyk to use next generation sequencing to reveal the incredible stress tolerance mechanisms of the Yukon native plant Thellungiella. The long term goal is use this knowledge to improve crop stress tolerance and sustainability.
2.8 million dollar ORF grant awarded to Dr. Herb Schellhorn and colleagues, to fund studies into water contamination by E. coli bacteria
Infection modelling by the Dushoff lab has provided key insights into the spread of HIV and influenza infections (as published in PLoS Biology and PNAS)
Recent work by the Evans lab has uncovered new amphibian species (as profiled on CBC), revealed variation in the genetic mechanisms for sex determination in frogs, and explored how social systems affect gene evolution in primates
Functional genomic analyses by the Finan lab (funded by Genome Canada) have significantly advanced our understanding of bacterial-plant symbiosis
The Golding lab is a national leader in understanding molecular evolution, and has provided important analyses into antibiotic resistance (Nature, 2011), and the bubonic plague (Nature, 2011)
Discoveries in the Elliot lab have revealed novel mechanisms governing bacterial development (PNAS, 2011), and led to the development of new strategies to stimulate antibiotic production (mBio, 2012)
Work in the Stone laboratory focuses on ‘big picture’ questions, as befits the Associate Director of the Origins Institute here at McMaster

Research

We study gene regulation and physiological adaptation in E. coli and other bacteria to better understand how bacteria cause disease and persist in the environment. We also have many collaborative projects with biochemists, engineers, industry and government agencies to develop new tools for monitoring water quality and understanding waste treatment processes from a microbiological perspective. We are using new DNA sequencing technology and bioinformatics analysis tools to track microorganisms, characterize composition of complex microbial communities and conduct comprehensive studies of gene expression.

Research Interests:

Bioinformatics & Functional Genomics; Genetics & Molecular Biology
