Teaching Activities

2010 – 2011          Technology for Biomed Research. Theory and Application of Cutting-Edge Technology for Biomedical Research. Physiology 221. I was invited to teach the students about epigenetics and techniques used to measure DNA methylation at the Translational Genomics Core at LSUHSC

2012                      “Epigenetics-Genomic Cores, Sequencing and Illumina Facilities,” Dr. Ed Grabczyk, PhD class INTER 122, Dr. Grabczyk, Department of Genetics. invited me to speak on the Translational Genomics Core to this interdisciplinary class.

2015                      Molecular Epidemiology, EPID 6213, Dr. Richard Scribner, Department of Epidemiology invited me to share with the students our experience on molecular determinants of risk of gastritis and gastric cancer in African American and Caucasian individuals.

2013 – present       Co-Director, BCHS 7350: CHS Translational Research, School of Public Health, Department of Behavioral and Community Health Sciences. In this class, we invite researchers who work on basic and clinical sciences to share with the students their work on the clinical field and how they bring all that knowledge into the laboratory to investigate molecular mechanisms of disease. We also invite basic researchers who work on fields with clinical applicability.

Committees & Administrative Responsibilities
