Being a Golden Hawk means more than just cheering on our (really good) varsity teams – it means being a student who cares about your community, who works hard in the classroom, and who takes advantage of all the learning opportunities that can happen outside the classroom, too.
I received my PhD in Biotechnology from the Universidad Nacional Autónoma de México. My first job after obtaining my PhD was at the Center for Research in Nitrogen Fixation, called now the Center for Genomic Sciences of the Universidad Nacional Autónoma de México. I spent two years as a visiting scholar at the USDA/ARS and Cornell University, and then came to Laurier as an associate professor in 2004.
Research Interests / Ongoing Projects
The focus of the Lab of Computational consequences is on the study, prediction, and evolution of genetic functional networks. The main data used is the sequence databases containing complete and draft genomes, as well as metagenomes (DNA sequences from random samples of a given environment). One of our main goals is the prediction and understanding of the functions of the vast amount of uncharacterized genes.
Student Opportunities / Supervising
I commonly supervise PhD, MSc, undergrad Theses, and undergrad directed studies. Please note that the work at the Lab of Computational conSequences is computer-based. You should have command of a programming language, like PERL or PYTHON, and familiarity with a UNIX-based operative system and the command line. Otherwise you still have to demonstrate that you have loads of energy to learn these skills. Don’t come to talk to me without having read and tried hard to understand a few of our most recent articles. I welcome proposals, but they have to be well investigated. Remember that any research project requires you to have a lot of energy, not only to carry on the necessary steps towards answering research questions, but also to continue reading the pertinent literature.
