Cell biology & Signal Transduction
Ever since beginning graduate work in the Bender lab at Harvard Medical School, Mark has been interested in how a fertilized egg self-assembles itself into an animal. As a postdoc with Eric Wieschaus at Princeton, he began work on ß-catenin, exploring its dual roles in cell adhesion and Wnt signaling. His lab at UNC began in 1992, and his team has continued and expanded this work, exploring cell adhesion, cytoskeletal regulation, and Wnt signaling in development and disease, using Drosophila and cultured mammalian cells. Outside the lab, he lives in the woods near Saxapahaw with his spouse and two daughters and is obsessed with native wildflowers and reducing global inequities in education and health care. Ask him about his trips to Haiti, or about the mystery flag which flies outside of his office.
Cell Division & Growth Control
Wu-Min Deng is a Professor at Florida State University. His lab is interested in how intercellular communications affect normal development and how disruption of such communications leads to abnormalities such as tumorigenesis in the Drosophila model system. Their current research has three major foci: (1) Characterization of “tumor hotspots” in Drosophila epithelial tissues; (2) Notch signaling in cell growth and tumorigenesis; and (3) the molecular mechanisms underlying postmitotic cell competition and compensatory cellular hypertrophy.
Cassandra Extavour is a Professor of Organismic and Evolutionary Biology and of Molecular and Cellular Biology at Harvard University. The Extavour laboratory is interested in understanding early embryonic development, the genes that control this development, the evolutionary origins of these genes, and how their functions have changed over evolutionary time. The lab is particularly interested in the development and evolution of reproductive systems, including both germ cells, which are cells that make eggs and sperm in sexually reproducing animals, and somatic gonad cells, which create the structures to house and protect the germ cells, and regulate egg and sperm production.
Chromatin & Epigenetics
Barbara Mellone is an Associate Professor of Molecular and Cell Biology at the University of Connecticut. Originally from Italy, she obtained her PhD in molecular genetics from the Medical Research Council in Edinburgh, Scotland, where she studied heterochromatin silencing mechanisms in S. pombe under the mentorship of Robin Allshire. For her postdoctoral training, Mellone moved to the US to join Gary Karpen’s group at LBNL and UC Berkeley to work on centromere assembly in Drosophila. She joined the faculty of the University of Connecticut in 2009, where she investigates centromere specification mechanisms. In 2016, she was the recipient of the American Society for Cell Biology Women in Cell Biology Junior Award for excellence in research.
Ting (C.-ting) Wu is a Professor of Genetics at Harvard Medical School. She is also Director of the Consortium for Space Genetics and Director of the Personal Genetics Education (pgEd.org) Project. Her group focuses on chromosome behavior and genome organization, and to that end, they also develop methods for imaging the genome in situ. Two such methods, OligoSTORM and OligoDNA-PAINT, enable ≤20 nm resolution. Her group also studies sequence ultraconservation in mammals and its potential role in maintaining genome integrity. Through pgEd, she works to enable equal access to awareness and dialogue about personal genetics and genetic technologies.
Evolution and Population Genetics
Maria Vibranovski received her PhD from the University of São Paulo in 2005 in Brazil. She won the prestigious award of a Pew Latin American Fellowship to pursue her scientific training in a postdoctoral research with Manyuan Long in the Department of Ecology and Evolution at the University of Chicago. She developed the first techniques for male germline cell dissection and generated the first large-scale gene expression database for the different phases of Drosophila melanogaster spermatogenesis. She and collaborators showed that Meiotic Sex Chromosome Inactivation drives the chromosomal evolution and distribution of male-biased expressed genes in Drosophila as well as showing that there is de novo RNA synthesis in male Drosophila post-meiosis, which was once thought to be transcriptionally inactive. Since 2012, Vibranovski is an Assistant Professor at the University of São Paulo investigating the impact of gametogenesis on the evolution of new genes.
Dmitri Petrov is a Michelle and Kevin Douglas Professor of Biology and Associate Chair of the Biology Department of Stanford University. He received his PhD in 1997 from Harvard University under the guidance of Daniel Hartl and Richard Lewontin. He was a Junior Fellow at the Harvard Society of Fellows and a Research Fellow in the Genetics Department at Harvard Medical School under the guidance of Chao-Ting Wu. Dmitri came to Stanford in 2000 as an Assistant Professor. The Petrov Lab does theoretical, computational and experimental work to address questions in molecular evolution and molecular population genomics. The primary focus at the moment is on (i) population genetics and molecular mechanisms of adaptation and (ii) genome evolution.
Ming Gao is a third-year tenure-track assistant professor in the Biology Department at Indiana University Northwest. In this primarily undergraduate institute, he engages mostly undergraduate students in germ cell genetics research. He is interested in how germ cells are specified during Drosophila oogenesis. He aims to find out how maternal proteins like maternal expression at 31B (Me31B) contribute to the assembly of germ plasm, a cytoplasmic determinant that leads to germ cell formation.
Katie Brennan is in her 5th year as an Assistant Professor at California State University, Fullerton, where her laboratory investigates the contributions of fly hemocytes to the immune response, as well as mechanisms that regulate phagocytic degradation of ingested microbes. Katie started this position after a 7-year hiatus from Drosophila research, which included 4 years of work on human HIV immunology. She earned her PhD with Kevin Moses studying fly eye development, followed by postdocs with Kathryn Anderson and David Schneider studying fly immunity.
Ylva Engström is a Professor of Molecular Biology and also Vice Dean of the Science Faculty at Stockholm University. She is known for discovering that Drosophila immune genes are regulated by NF-kB/Rel and GATA transcription factors, and more recently that POU transcription factors control immune gene expression in barrier epithelia. She currently studies a novel regulatory mechanism of host-microbe interactions and gut immune homeostasis, mediated by antagonistic transcription factor isoforms. This has also led into studies of gut microbial communities, as well as gut epithelium regeneration and intestinal stem cell regulation.
Amy Kiger is an Associate Professor at the University of California, San Diego. Her laboratory examines central roles for novel membrane trafficking processes, under control of spatiotemporal lipid regulation, that coordinate dynamic cell structure. Using a foundation in genetic and cell biology experiments to link specific lipid kinase and phosphatase activities to cell remodeling, they aim to identify conserved mechanisms of membrane regulation in immune and muscle cell function, to provide insights into related human diseases.
Blake Riggs uses his own story of prejudiced encounters, personal stumbles, and the eventual discovery of his own tenaciousness to help increase diversity in the sciences. He earned a PhD in molecular, cell and development biology, completed his postdoctoral work at UC Berkeley, and now works as an Assistant Professor of Cell and Molecular Biology at San Francisco State, where he runs a lab that is working to better understand the process of cell division and selection of cell fate. Last year, Riggs was awarded a prestigious National Science Foundation CAREER grant for excellence in teaching and research.

Kristi Wharton is a Professor of Biology at Brown University and affiliated with the Brown Institute for Brain Science (BIBS). Throughout her career, her research has focused on understanding the mechanistic underpinnings of intercellular signaling regulation during development, and the consequences of signaling dysfunction that results in developmental abnormalities and disease.
Neural Development & Physiology
Vanessa Auld is a Professor in the Department of Zoology at the University of British Columbia and was the Associate Dean of Equity and Diversity. Her research program investigates the roles that glia play in the development and function of the nervous system. Glia are essential to nervous system development and function, and a key role is the formation of the glial wrap that protects and insulates their associated axons and nerves and generates the blood-brain barrier. In particular in Drosophila, loss of glial sheath results in the disruption of the blood-brain barrier, resulting in paralysis and death. Critical to the formation of the glia sheath is adhesion between glia themselves and between glia and the extracellular matrix. Yet how glial cell adhesion and communication is regulated during the formation of the glial sheath is not well established. Junctions such as septate junctions, gap junctions, and adherens junctions are all key players in the establishment of the glia sheath, and mediate not only development but are also key to the stability of the sheath as the nervous system expands during larval development. How these functions mediate glial sheath development and stability is the main focus of the research in the Auld Lab.
Jennifer Jemc is an Assistant Professor of Biology at Loyola University Chicago. Her lab is interested in the molecular mechanisms that regulate the establishment of cell-cell interactions during development and the maintenance of organ homeostasis in the adult. Specifically, the lab focuses on the interaction of somatic gonadal cells and germ cells in the gonad, and neurons and glia in the nervous system. Recent work in the lab has demonstrated that altered JNK signaling can lead to developmental defects in both of these contexts.
Physiology, Metabolism, & Aging
Thomas Merritt combines the power of bioinformatics, functional genomics, and experimentation to explore metabolism and genetic networks. Merritt’s group studies the interactions between genes, genetic backgrounds, and the environment in a variety of stress response systems. In one project, they are using metabolomics and the SNOLAB particle physics laboratory, located 2 km underground in an active mine, to understand deep underground physiology. Other projects investigate oxidative stress and the NADP(H) enzymes. Merritt’s contributions also extend beyond the research setting and into the non-scientific community. As a committed science communicator and partner with Science North, Canada’s second largest science centre, Merritt has shared the importance of genetics research as a TEDx speaker, educator, and as a contributor to news sources. His article on trapping flies – and the science of model species – was the most read article of 2017 at TheConversation.ca, an online academic news source. In 2017, Merritt partnered with a local primary school to set a world record for most people isolating DNA at one time.
Nicole C. Riddle is an Assistant Professor in the Department of Biology at the University of Alabama at Birmingham.
