Sarah K. England

England was born in St. Paul, Minnesota.[1] Her family moved to the Highland Park neighbourhood in 1969 after the Fair Housing Act was passed so that England and her four brothers could obtain a better quality education.[1] England's father was a physician and her mother worked in real estate and they made sure that education was a priority in the family.[1] England had always loved science, and decided to pursue a career in academia instead of medicine.[1]

In 1984, England pursued her undergraduate degree at Carleton College, a small private liberal arts college in Northfield, Minnesota.[2] She majored in biology and conducted research under the mentorship of John W. Osborn at the University of Minnesota in St. Paul studying the sympathetic nervous system response after barodenervation.[3] This led to her first publication in the American Journal of Physiology in 1990.[3] England completed her Bachelor of Arts in 1988, and then in 1989, she pursued her graduate training in physiology at the Medical College of Wisconsin.[1] She studied under the mentorship of Nancy J. Rusch exploring the role of cation channels in hypertension.[4] She found that calcium dependent potassium channel function is aberrant in specific patches of arterial muscle in rats in rats with genetic hypertension.[4] The potassium channels had a higher probability of open-state leading to increased potassium permeability and overall dysregulation of membrane excitability and contraction.[4] England completed her graduate studies in 1993.[5]

Following her graduate work, England pursued her postdoctoral work at Vanderbilt University under the mentorship of Michael M. Tamkun in the Department of Molecular Physiology and Biophysics.[5] She continued to study voltage-gated potassium channel biophysics, exploring the role they play in smooth muscle tone in the vascular system and how their activity is implicated in blood pressure regulation.[5] She published a first author paper in the Proceedings of the National Academia of Sciences in 1995 characterizing the presence and functionality of beta subunits of voltage-gated potassium channels in human heart tissue.[6] Her findings highlighted the possibility that potassium current diversity in the heart is in part due to the function and expression of beta subunits for voltage-gated potassium channels.[6] She also discovered a novel potassium channel beta subunit, cloned from human heart tissue. She found that this beta-subunit she discovered is generated from alternative splicing of a beta-subunit gene which gives rise to two other previously discovered beta-subunits.[6] Her discovery of alternative splicing mechanisms suggests that potassium channel current diversity and heart tissue excitability diversity may be in part due to alternative splicing events.[6] England completed her postdoctoral training in 1997.[7]

In 1997, England was appointed to the faculty at the University of Iowa, becoming an Assistant Professor in the Carver College of Medicine in the Departments of Molecular Physiology and Biophysics.[7] While at U of I, England turned her research focus towards exploring ion channel function in the uterus during pregnancy.[7] England became a Full Professor of Obstetrics and Gynaecology, and well as a full professor in pediatrics.[8] She was also appointed special assistant to the Vice President of Medical Affairs at U of I.[9]

England lead many educational programs to enhance diversity and inclusion in the institute.[10] England became a Co-Director of the Iowa Biosciences Advantage Program, which is a National Institutes of Health funded program that aims to increase the participation and recruitment of minority students in biomedical graduate degrees.[11] In addition to being a student mentor in the program, England worked hard to improve the program and make it an established and mainstay program at U of I.[11]

From 2005–2006, England took a one-year leave from her roles at the University of Iowa to become a Robert Wood Johnson Foundation Health Policy Fellow in the Office of Senator Hillary Rodham Clinton on Capitol Hill.[12] During this time, she helped draft legislations on issues related to her research on preterm birth and pregnancy, efficiently linking her science to policy changes.[1] She also focused much of her fellowship work to policies more generally surrounding maternal child health, women's health, and health disparities.[7]

In 2011, England joined the faculty at the Washington University School of Medicine in St. Louis, Missouri.[1] She became a Professor of Obstetrics and Gynaecology, as well as the Vice Chair of Research for the Center for Reproductive Health Sciences and in 2015, was appointed the Alan A. and Edith L. Wolff Professor of Medicine.[13] Funded by the March of the Dimes, England serves as Associate Program Director and Theme 3 Leader of the Prematurity Research Center at Washington University, working with a team of researchers across the university[7] and across the world to end prematurity.[14]

England is also the Principal Investigator of the England Lab where she explores the physiology of ion channels in smooth muscle as a means to target these mechanisms in muscle diseases.[15] She focuses on both vascular and uterine smooth muscle, with a specific focus on the implications of uterine ion channels in preterm birth.[15] One of her projects explored the localization and activity of BK channels and how they alter myometrial excitability and uterine contractility.[16]
