I have a passion for understanding how living systems work, as well as for sharing my love of biology and research with the next generation of scientists and informed citizens.

The central goal of my lab is to understand the regulatory mechanisms that underlie mycobacterial stress tolerance. We combine genetics, genomics, transcriptomics and biochemistry to understand how mycobacteria respond to, and ultimately survive, stressful conditions.

Our guiding principles are curiosity, respect, and scientific rigor. Together we strive to push the boundaries of knowledge and advance our field by addressing basic research questions that hold the keys to advancements in human health and understanding of the natural world.

Caption

To treat many infectious diseases, including the global scourge of tuberculosis, doctors must do battle with a wily adversary, bacteria. Unfortunately for afflicted patients, bacteria have also acquired strategies for thwarting attacks from the immune system and the onslaught of antibiotic drugs. We need to know more about the strategies bacteria use to survive stresses. Biology and biotechnology professor, Scarlet Shell, is seeking to do just that by probing the molecular changes that underlie these mechanisms.
