Karmella Ann Haynes is a biomedical engineer and associate professor at the Wallace H. Coulter Department of Biomedical Engineering, Georgia Institute of Technology and Emory University. [1] [2] She researches how chromatin is used to control cell development in biological tissue.
Haynes was born and raised in St. Louis. [3] She received her B.S. in biology from Florida A&M University (where she had received a full scholarship) in 1999 . [4] [5] While at Florida A&M, she participated in a summer research program working with Mary-Lou Pardue at Massachusetts Institute of Technology as part of the MIT Summer Research Program. [6] [7] [8]
Haynes did her graduate work in the lab of Sarah Elgin at Washington University in St. Louis. [4] [6] She received her Ph.D. in molecular genetics in 2006 for her work studying chromatin dynamics and epigenetics in Drosophila. [9] [10] [11] [12]
As a Howard Hughes Medical Institute fellow, she completed her first postdoctoral fellowship in teaching at Davidson College under the guidance of Laurie Heyer and Malcolm Campbell. [4] [5] During her time as a fellow, Haynes redesigned the undergraduate bioinformatics teaching course and won publication of the year from the Journal of Biological Engineering for her article Engineering bacteria to solve the Burnt Pancake Problem. [13] [14] [15] [16] [17] She was introduced to synthetic biology and became a member of Davidson's 2006 iGEM team. [18]
Haynes went on to complete a second postdoctoral fellowship in Pamela Silver's lab at Harvard Medical School where she leveraged her experience with chromatin dynamics and synthetic biology to create artificial transcription factors which activated genes based on histone methylation. [6] [19] [12]
After her postdoctoral fellowships in 2011, Haynes started her lab in the School of Biological and Health Systems Engineering at Arizona State University (ASU). [20] [21] There, her lab focused on creating epigenetic machinery that can regulate DNA. [22] The proteins themselves are fusion transcription factors, which can target particular genes. [23] She hopes to increase the use of technology in therapeutics, working on tissue regeneration and customizable protein-based drugs. [24] In 2015 she was awarded a K01 grant to study the use of modular peptide motifs to build synthetic chromatin proteins that activate dormant therapeutic genes. [25] During her time at ASU, she was the faculty advisor for the ASU iGEM team. [26]
In 2018, Haynes moved to the W.H. Coulter Biomedical Engineering Department at Georgia Tech/Emory University. [27] [5] During her time here, she founded the AfroBiotech conference and the Cold Spring Harbor Summer Course on Synthetic Biology. [28] [29] She was on the responsible conduct committee for IGEM in 2018 and 2019. [30] [31]
Haynes has appeared on PBS, talking about biotechnology and disease. [32] Alongside research, Haynes is an accomplished artist. [33] [34] In 2011, she painted her poster presentation for the Fifth International Meeting of Synthetic Biology (SB5.0) conference. [35] Her artwork is still on the walls at Harvard University. [6] She is a member of the Building with Biology public engagement project. [36] She has been featured twice on Science Friday. [37]

Synthetic biology (SynBio) is a multidisciplinary field of science that focuses on living systems and organisms, and it applies engineering principles to develop new biological parts, devices, and systems or to redesign existing systems found in nature.
Pamela Ann Silver is an American cell and systems biologist and a bioengineer. She holds the Elliot T. and Onie H. Adams Professorship of Biochemistry and Systems Biology at Harvard Medical School in the Department of Systems Biology. Silver is one of the founding Core Faculty Members of the Wyss Institute for Biologically Inspired Engineering at Harvard University.
Position-effect variegation (PEV) is a variegation caused by the silencing of a gene in some cells through its abnormal juxtaposition with heterochromatin via rearrangement or transposition. It is also associated with changes in chromatin conformation.
Chromatin remodeling is the dynamic modification of chromatin architecture to allow access of condensed genomic DNA to the regulatory transcription machinery proteins, and thereby control gene expression. Such remodeling is principally carried out by 1) covalent histone modifications by specific enzymes, e.g., histone acetyltransferases (HATs), deacetylases, methyltransferases, and kinases, and 2) ATP-dependent chromatin remodeling complexes which either move, eject or restructure nucleosomes. Besides actively regulating gene expression, dynamic remodeling of chromatin imparts an epigenetic regulatory role in several key biological processes, egg cells DNA replication and repair; apoptosis; chromosome segregation as well as development and pluripotency. Aberrations in chromatin remodeling proteins are found to be associated with human diseases, including cancer. Targeting chromatin remodeling pathways is currently evolving as a major therapeutic strategy in the treatment of several cancers.
Dame Caroline Dean is a British plant scientist working at the John Innes Centre. She is focused on understanding the molecular controls used by plants to seasonally judge when to flower. She is specifically interested in vernalisation — the acceleration of flowering in plants by exposure to periods of prolonged cold. She has also been on the Life Sciences jury for the Infosys Prize from 2018.
Cellular memory modules are a form of epigenetic inheritance that allow cells to maintain their original identity after a series of cell divisions and developmental processes. Cellular memory modules implement these preserved characteristics into transferred environments through transcriptional memory. Cellular memory modules are primarily found in Drosophila.
Epigenome editing or epigenome engineering is a type of genetic engineering in which the epigenome is modified at specific sites using engineered molecules targeted to those sites. Whereas gene editing involves changing the actual DNA sequence itself, epigenetic editing involves modifying and presenting DNA sequences to proteins and other DNA binding factors that influence DNA function. By "editing” epigenomic features in this manner, researchers can determine the exact biological role of an epigenetic modification at the site in question.

Lubin is the Principal Investigator of the Lubin Lab which explores the epigenetic mechanisms underlying cognition and how these mechanisms are altered in disease states such as epilepsy and neurodegeneration. Lubin discovered the role of NF-κB in fear memory reconsolidation and also uncovered a novel role for epigenetic regulation of BDNF during long-term memory formation and in epilepsy leading to memory loss. Lubin is a champion for diversity at UAB as the Director of the Roadmap Scholar Program and as a faculty mentor for several institutional and national programs to increase retention of underrepresented minorities in STEM.
