The Lucks Group aims to understand and harness the ability of RNA molecules to control cellular processes for an array of applications in biomanufacturing, diagnostics and disease. Our focus is on making RNA a powerful molecular substrate for engineering gene expression by leveraging its functional versatility, our ability to control its function by designing its structure, and our ability to characterize its biochemistry and biophysics in unprecedented throughput and scale with next generation sequencing tools that we have pioneered. Specifically, we: (1) Engineer new RNA regulatory mechanisms and build RNA genetic networks to precisely program gene expression in applications that range from metabolic engineering to smart diagnostics; and (2) Develop new technologies to uncover RNA sequence/structure/function relationships that feed back into our RNA engineering. We also use our tools to understand natural RNAs that regulate fundamental cellular processes and diseases.

Our research is highly interdisciplinary and links core concepts from chemical engineering, physics, and molecular and structural biology to develop theoretical and experimental techniques for understanding and controlling cellular function with RNAs. To do this we utilize both wet lab and computational techniques. In the wet lab, we use methods spanning molecular biology and biochemistry to next generation RNA sequencing technologies to measure RNA structures in a massively parallel fashion. On the computational side we develop models of RNA genetic networks, develop new techniques for computational RNA design and develop new RNA structure prediction algorithms.

Our current research activities are structured into two thrust areas: (1) Engineering enhanced RNA genetic regulators and networks for control of cellular systems, with a growing interest in using these regulators in cell-free smart diagnostics, and (2) Uncovering the biological design principles of cellular RNA folding and function by developing and applying our SHAPE-Seq technology for measuring RNA structures with next-generation sequencing. These two areas are synergistic, with engineering projects identifying gaps in our knowledge that are filled through fundamental biology investigations.
