PhD Defense – Congratulations to Cassandra Barrett!

Posted on Updated on

Biological Design PhD student Cassandra Barrett just successfully defended her thesis “Engineering Open Chromatin with Synthetic Pioneer Factors: Enhancing Mammalian Transgene Expression and Improving Cas9-Mediated genome Editing in Closed Chromatin” today at 10:00 – 11:00 am in the Biodesign Institute building, room AL1-10/14. Thank you to all of the friends, family, and colleagues who came to show their support.

Cassandra joined the Haynes lab in 2015. Since then she has co-authored two research papers, and is lead author on one review article and one upcoming research article. She has been highly engaged with the broader community through science education and leadership. She served as president of the Engineering Biology Research Consortium (EBRC) president of the student and postdoc association (SPA), was an ASU iGEM mentor, was involved in an AZ State biotechnology policy project, and volunteered to teach bioengineering at a local prison. She aims to pursue a long term career in biotechnology.

Masters Defense – Congratulations to Fatima Hamna!

Biomedical Engineerng MS student Fatima Hamna just successfully defended her thesis “Opening Chromatin and Improving CRISPR/Cas9 Editing” today at 2:30 – 1:30 pm in Physical Education Building East, Room 157. Thank you to all of the friends, family, and colleagues who came to show their support.

Hamna joined the Haynes lab in 2017 after learning about synthetic biology and earning top marks in Dr. Haynes’ Molecular Synthetic Biology course. She was a Fullbright Scholar and a recipient of the ASU Fulton Schools of Engineering MORE award for independent research. She aims to pursue a long term career in research with a specific focus on CRISPR-based technologies.

Research – Frontiers – Engineered orthogonal quorum sensing systems for synthetic gene regulation

Engineered orthogonal quorum sensing systems for synthetic gene regulation
Tekel SJ, Smith CL, Lopez B, Mani A, Connot C, Livingstone X, Haynes KA. (2019) Front Bioeng Biotech. doi: 10.3389/fbioe.2019.00080 (just accepted)

For the past two years, the undergraduate ASU International Genetically Engineered Machines (iGEM) Competition teams have been investigating the use of quorum sensing to build bacteria (E. coli) that can carry out chemical signaling with each other, without signaling to a different group of bacteria. In a continuation of the quorum sensing project from the 2016 team, the 2017 ASU iGEM team built and tested six new quorum sensors (Receivers) in addition to the previous sensor, LuxR. After exposing a total of seven Receivers to HSLs from ten different synthases (Senders), the team identified two sets of signaling pathways that exhibited orthogonal behavior. These results expand the toolbox of characterized components for engineering microbial communities. The plasmid constructs featured in this paper were contributed to public collections for use by the scientific community.

Dr. Haynes receives membership in Emory Winship Cancer Genetics and Epigenetics program

Posted on

Dr. Haynes is one of the newest members of the Cancer Genetics and Epigenetics program at the Emory Winship Cancer Institute. The goal of this research program is to better understand the fundamental mechanisms underlying genetic and epigenetic instability, and how these factors contribute to the onset and progression of human tumors with the goal of exploiting these mechanisms to reduce cancer mortality.
