Our Research:

Our research combines biomolecular engineering, genetic studies and computational modeling to understand molecular features that lead to the specific recognition and interaction of regulatory RNAs and proteins. We apply fundamental concepts that emerge from experimental (and computational) work to develop novel applications that could beneficially impact human health and biotechnology. Overall research interests: *transcriptional regulation, *regulatory RNA networks, *epitranscriptomics,  * RNA-protein interactions, RNA-protein folding * Novel molecular tools for intracellular studies of RNA-metabolism *  * Diagnostics for RNA-related diseases * Molecular mechanisms of stress-responses

 

Our Team Values:

Our lab strives to be at the forefront of exciting scientific discoveries in the field of RNA biology. To accomplish this, we value a strongly cohesive and team-oriented environment where we encourage and respect each other. We value the contribution of every member towards creating and sustaining a safe, stimulating, and engaging environment for intellectual growth. 

We believe that a collaborative, professional, and diverse environment fosters creativity and excellence in our field. Therefore, the Contreras group is committed to maintaining an inclusive environment for every student, at every level, regardless of race, age, citizenship status, national origin, gender, gender-identity, sexual orientation, religion, marital/parental status, veteran status, or physical/ mental abilities.
