Brandon Davies, PhD

Principal Investigator

Regulation of lipid homeostasis has been the consistent theme of my scientific career. As an undergraduate at the University of Utah, I studied cholesterol trafficking. As a graduate student at Berkeley, I studied two transcription factors that regulated the synthesis of ergosterol (the yeast version of cholesterol), and then as a post-doc at UCLA I started my work on the role of endothelial cells in regulating triglyceride metabolism. I also like to eat lipids. Aside from lipids, I am a long time biker. Although moving to Iowa has reduced the amount of time I spend mountain biking, it has added additional climatic elements to my bike commute and allowed me to expand the temperature range in which I have successfully biked to lab (current range -24 degrees [-41 with windchill] to 110 degrees).

Research Assistant

I grew up and studied Bachelor of Engineering in Biotechnology from India, then did M.S. from Stephen F. Austin State University. Before coming to Iowa I worked as a Research Associate at UTHSCT, Tyler, Texas and IPSEN Pharmaceuticals, MA. My lab experience got me interested in gene expression and regulation. Fortunately, I got the chance to work under Dr. Davies and I am greatly enjoying working with him and now exploring ways to express GPIHBP1 in cell culture.

Kelli Davie 

Graduate Student

Before starting at the University of Iowa, I graduated from the College of Saint Scholastica in Duluth, MN with a bachelors in Biochemistry and Biology. My current research interest is understanding how Endothelial Lipase is regulated by ANGPTL proteins. Outside of lab, my interests include watching The Office on repeat, coffee, cats, spending time with my husband, and having board game nights with friends.

 


Ashley Segura

Undergraduate Student

I am currently a senior at Iowa, majoring and honoring in Biochemistry. In lab, I am working on experiments to quantify binding between lipases and their inhibitors. My other lab duties include keeping the graduate students up to date on current memes and dance moves. After graduation, I will be starting my graduate career at the University of California Berkeley.

I highly recommend the Morning muscle breakfast sandwich from Java house: 12/10

Emil
y Malcolm Cushing

Graduate Student (2013-2018)

Originally from Arkansas, Emily received her B.S. in Chemistry and Biology from the University of Central Arkansas in 2007 and her M.S. in Chemistry from Georgia Tech in 2010.  She joined the Biochemistry program at the University of Iowa in 2012, and became the first graduate student to join the Davies lab in 2014. Emily defended her thesis "Regulation of Plasma Triglycerides by ANGPTL4 and GPIHBP1" in 2018. After graduating, Dr. Cushing began her postdoc in the lab of Alan Attie at the University of Wisconsin-Madison.

Allison (Xun) Chi

Graduate Student (2013-2017)

Two months after finishing her undergraduate degree in China in 2012, Allison came to Iowa to begin her graduate studies in the department of Biochemistry. She joined the Davies lab in the spring of 2013. In 2017 Allison defended her thesis, "Extracellular Regulation of LPL Activity by Angiopoietin-like Proteins" and became the first student to get her PhD from the Davies Lab. Allison then joined the lab of Steve Bensinger at UCLA for her postdoc.

Hannah Shows

Undergraduate Student (2013-2015)

Hannah joined the Davies’ lab at the end of her freshman year, becoming the first undergraduate to join the lab. Although Hannah never fulfilled her dream of studying triglyceride metabolism in live grizzly bears she did finish her degree in Biochemistry in December 2015. In the fall of 2016 she started graduate school at Wright State University, eventually joining the lab of Kate Excoffon.

Alex Hjelmaas

Undergraduate Student (2013-2015)

Alex joined the Davies lab at the beginning of his Junior year. While in the lab Alex was awarded an ICRU Summer Research Award and the H.G Wittman Scholar Award. Alex also promised that he would continued to work in the lab until the Cub won the World Series. Despite this promise, Alex graduated in Spring 2015 and then attended medical school at the University of Michigan. The Cubs did not win the World Series until November 2016. Alex you still owe us a year and a half of lab work.
