Passionate About Helping Others
I grew up in Trinidad and Tobago and have always been interested in science. I enjoy interacting with students and investigating intracellular signaling that has not been previously explored.
Outside the lab I enjoy traveling with my family, hiking, drawing, painting, modern technology and movies.

Muscle Physiology and Proteomics Laboratory
Impaired protein degradation is associated with many cardiac and skeletal muscle diseases. Our laboratory is interested in investigating the signaling pathways involved in proteostasis (protein homeostasis) in cardiac and skeletal muscle diseases. Our laboratory is also interested in the side effects of commonly used drugs, such as ibuprofen, on the heart.

Areas of Research
The Molecular Mechanisms involved in the Side Effects of Commonly used Drugs Such as Ibuprofen
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used drugs worldwide. NSAIDs are used for pain, rheumatoid arthritis, and musculoskeletal disorders. The beneficial effects of NSAIDs in relieving pain are well established, and other benefits such as reducing inflammation and anticancer effects are also documented. The undesirable side effects of NSAIDs include ulcers, internal bleeding, kidney failure, and increased risk of heart attack and stroke. We are interested in what intracellular molecular pathways are involved in causing these side effects and how to prevent them.
The Role of the Proteasome in Cardiovascular Disease
Many students were taught that the lysosome was responsible for most of the intracellular protein degradation. However, it is the proteasome that is responsible and can up to 80% of all the intracellular proteins. The proteasome is a multicatalytic threonine protease complex that is a part of the ubiquitin proteasome system (UPS). The UPS has been increasingly recognized as an integral component in numerous biological processes, including cell proliferation, adaptation to stress, and cell death. The turnover of intracellular proteins inevitably affects the contributions of these molecules to cellular networks and pathways in any given tissue or organ, including the myocardium.
Role of Proteasome in Cardiomyopathies: Proteasome inhibitors block activities of the 20S and 26S proteasomes. In general, inhibition of UPS-mediated protein degradation by proteasome inhibitors leads to accumulation of proteasome substrates, including cyclins, transcriptional factors, tumor-suppressing proteins, and protooncogenes. The activity of the proteasome is significantly affected in cardiomyopathies and the role of the proteasome in these cardiomyopathies is currently being investigated. The proteasomes are also involved in Alzheimer’s, Parkinson’s, Cancer and Diabetes.
How to improve University/Life Balance
Everyone encounters stress at some time. Achieving a healthy University/life balance can improve relationships, stress management and productivity. Our motto in the lab is “Work Hard but also Play Hard.” As such we are always interested in ways to have fun and enjoy life outside the lab with the friends we made in the lab.
