Promega qPCR Grant Series #2: Molecular Biologist, Laura Leighton

Posted on by Anna Bennett

Our second installment of the Promega qPCR Grant Recipient blog series highlights Dr. Laura Leighton, a trained molecular biologist and postdoctoral researcher at the Australian Institute for Bioengineering and Nanotechnology. Leighton’s scientific journey features a passion for molecular biology and problem-solving. Her path has been illuminated by mentorship, relationships with fellow scientists and a commitment to creativity in overcoming challenges. Here, we explore her scientific journey, reflect on research lessons and foreshadow her plans for the Promega qPCR grant funds.

Dr. Laura Leighton grew up in a rural area in Far North Queensland, Australia, where she spent her early life exploring critters on the family farm. Her upbringing was infused with a deep connection to the environment, from raising tadpoles in wading pools to observing wildlife and witnessing food grow firsthand. Observing the biology around her ultimately piqued her interest in science from a young age. She then began her academic journey in 2011 at the University of Queensland, Australia. She studied biology while participating in a program for future researchers, which led her to undergraduate research work in several research labs.  She dabbled in many research avenues in order to narrow in on her scientific interests all while adding different research tools to her repertoire.

After serving as a research assistant in Dr. Timothy Bredy’s lab, she decided to continue work in this lab and pursue a PhD in molecular biology. During her PhD, Leighton worked on several projects from cephalopod mRNA interference to neurological wiring in mice. The common thread in these projects is Leighton’s passion for the puzzles of molecular biology:

“I also love molecular engineering and the modularity of molecular parts. There’s something really special about stringing together sequence in a DNA editor, then seeing it come to life in a cell,” she says.

Synthetic Biology: Minimal Cell, Maximal Opportunity

Posted on by Ken Doyle

According to the National Human Genome Research Institute, synthetic biology is “a field of science that involves redesigning organisms for useful purposes by engineering them to have new abilities”. Synthetic biology has a broad range of applications, from manufacturing pharmaceuticals and other biologically active chemicals and biofuels, to accelerating the adoption of plant-based burgers (1).

At the heart of the synthetic biology revolution is the rapid technological advancement—and accompanying drop in costs—of DNA oligonucleotide synthesis. Typically, synthetic biology researchers use oligonucleotides as building blocks to assemble genes of interest that are then introduced into, and expressed by, a different organism. For example, to create the plant-based Impossible Burger, the soy leghemoglobin gene (normally found in the root nodules of leguminous plants) was synthesized and expressed in yeast cells (1). This component gives the burger its meaty flavor and appearance of “bleeding” when cooked.

Announcing the 2019 Promega iGEM Grant Winners

Posted on by Jordan Villanueva

It’s FINALLY time to announce the winners of the 2019 Promega iGEM Grant! We received over 150 applications this year, so picking the top 10 was very tough. As always, we’re impressed by the amazing work iGEM teams are doing in the lab and in their communities. The 10 winners listed below will receive $2,000 in free Promega products.

Good luck to all teams competing in iGEM this year, and congratulations to our winners! Don’t forget that Promega has free technical support for all teams competing in iGEM. Our scientists are excited to help out. You can also check out our iGEM Sponsor page, which has tools and resources to help make your project a success.
