Rebecca Alexander

Rebecca Alexander is a Professor in the Department of Chemistry at Wake Forest University and currently serves as the Associate Dean for Research and Community Engagement. Her research focuses on the molecular mechanisms of protein synthesis, particularly the role of tRNA-acting enzymes in establishing and maintaining the genetic code.

Education:

• B.S., University of Delaware, 1990 (Honors)
• Ph.D., University of Pennsylvania, 1996 (Advisor: Barry S. Cooperman)
• Postdoctoral Research Associate, MIT, 1996–1997 (Advisor: Paul Schimmel)
• Postdoctoral Research Associate, The Scripps Research Institute, 1997–1999 (Advisor: Paul Schimmel)

Her research interests lie at the intersection of biochemistry, molecular biology, and biophysics, with a focus on aminoacyl-tRNA synthetases, tRNA modification, translational fidelity, RNA dynamics, and molecular evolution. She employs both experimental and computational approaches to understand how these enzymes recognize their substrates and maintain accuracy in protein synthesis. Her work has implications for understanding fundamental biological processes, disease mechanisms, and the origins of life.

The analysis of her recent publications reveals a consistent focus on tRNA and synthetase function, with increasing integration of computational methods such as molecular dynamics. Her work spans from mechanistic enzymology to evolutionary questions about the genetic code. Key themes include domain communication in synthetases, tRNA structural dynamics, and the role of RNA modifications in cellular adaptation.

Scientific Awards:

• Robert P. and Debra Lee Faculty Fellowship (2008–2011)
• F. M. Kirby Family Faculty Fellowship (2014–2017)

While specific names of her advisees are not listed in the provided text, her extensive publication record with multiple collaborators and first-author students suggests active mentorship in research. She has not mentioned external grant funding in the provided text, but her sustained research output and fellowships indicate strong institutional and likely external support. Her role as Associate Dean highlights leadership in research administration and community engagement.

Her research is conducted within the Department of Chemistry at Wake Forest University, likely involving a dedicated laboratory team focused on RNA-protein interactions and enzyme mechanisms. She collaborates with computational and structural biologists, as evidenced by co-authored works involving molecular dynamics and biophysical analysis.
