During a summer research program when she was a biochemistry undergrad at Abilene Christian University in Texas, Rebecca Ann Faulkner worked in a polymer chemistry lab that synthesized compounds for biomedical applications. This experience inspired her to study biomedical science.

At the University of Texas Southwestern Medical Center in Dallas, Faulkner earned a Ph.D. in cellular and molecular biology with an emphasis on cell regulation. Her research focused on the pathways in the cellular quality control system that balance protein synthesis and degradation. She was particularly interested in endoplasmic reticulum–associated degradation, or ERAD, of integral membrane proteins with special attention on the enzyme that catalyzes the rate-limiting step in the mevalonate pathway, which synthesizes sterols and is, therefore, a molecular target of drugs, including statin drugs that are used to treat lipid disorders.

Faulkner pursued postdoctoral training with at UTSW. Her collaborative project identified and characterized a protein complex involved in retromer-independent endosomal cargo recycling, a novel cargo-sorting complex that contributes to maintaining cellular homeostasis.

“I was fascinated by how interconnected cellular processes are and how their dysregulation can lead to disease,” she said.

In 2016, Faulkner paused her career for four years to focus on her family, a decision that she believes made her a more effective and empathetic scientist.

“Stepping away from the lab to raise my children gave me a renewed perspective and a deeper understanding of the importance of work–life balance,” she said. “I returned to science with a clear vision of what I wanted to achieve and a passion to explore lipid metabolism further.”

Faulkner's research is now centered on that regulate lipid homeostasis. Her recent findings have shown that sterols directly interact with the membrane domain of this enzyme to initiate sterol-induced endoplasmic reticulum–associated degradation. This work has implications for strategies to combat hypercholesterolemia and atherosclerosis.

“Our research could lead to alternative treatments for cardiovascular diseases, which is incredibly exciting,” she said.

Faulkner is now a scholar in the 偷拍偷窥 and 偷拍偷窥 Biology’s Maximizing Opportunities for Scientific and Academic Independent Careers, or MOSAIC, program, which provides recipients of National Institutes of Health K99/R00 awards with mentorship, grant-writing workshops, peer networking and other professional support.

“The MOSAIC program has been instrumental in my career development, providing me with the tools and support needed to advance my research,” she said.

The program's emphasis on diversity and inclusion resonates with Faulkner. “I’m committed to helping other scientists find that balance between career and family, just as I have,” she said.

She encourages aspiring scientists to seek out mentors and collaborators who can provide guidance and support, emphasizing that diverse perspectives and experiences are crucial for scientific innovation.

“Don’t be afraid to take a different path,” she said. “With determination and the right support, you can achieve excellence in science while maintaining a fulfilling personal life.”
